All man is, all he ever has been, has had its original motif in his need for food, and in the means he has evolved in order to secure it. History itself, in the main, is merely a series of accounts of how certain peoples pushed cer- tain other peoples out of the way, in order to avail themselves of the others' food supply, or of their potential sources of food. Ethnologists and students of anthropology also tell us that by far the most important de- termining factor in racial development is the character of food upon which any people has lived. It has governed their stature, their in- telligence, or lack of intelligence, their disposi- tion. Upon whether a race is well or poorly nour- ished depends its status as conquerors, quest- ing, energetic, civilization-making; or as docile serfs, blood-brothers to the cabbages, manioc, or rice they cultivate. Upon the difficulty of securing an adequate 9 10 Preface — Continued supply of balanced nutriment depends also their cultural development ; for, if the aim and end of existence revolves around a grubbing of arid acres, it is obvious that not much en- ergy can remain for speculative and creative endeavor. However, it is with the physiological aspects of food, as they concern the individual, that our attention is now engaged. In this con- nection, one might rather expect that in the half million or more years in which human beings have been inhabiting this planet, they would have developed an ample and adequate understanding of the uses of food, or an in- stinctive if not an acquired knowledge of proper food selection. Such is not the case. Even the greatest scholars have shown, and still show, a lamen- table ignorance of food and its functions. The sour and crabbed Carlyle is a horrible example of this ignorance. Living for years, as he did, upon oatmeal — one of the poorest sources of nutriment a human could ever put into his stomach — Carlyle exhibited, all his life, the results of chronic intestinal auto-in- toxication, plus a distressing unappreciation of food value; while Herbert Spencer, with all his vast wealth of information, did not Preface — Continued 11 know enough to select a regimen that would have lifted him out of the slough of chronic dyspepsia. The great Napoleon, for all his genius, proved himself the victim of his own gastronomic sins; for if he had taken time properly to masticate and insalivate his food, instead of making good his brag that he never spent more than ten minutes at a meal, he might have segregated England, instead of be- ing segregated at St. Helena. What is even more surprising, hc)wever, is that many medical men, among them men who have won an enviable reputation as physiolo- gists and clinicians, are almost equally at sea respecting the uses and the proper selection of food. So conflicting has been their experi- ences, so confusing their findings, that hardly any two modern authorities agree upon even the fundamentals of the science of nutrition. The result has been that the laity, who look to medical men for authoritative advice on the subject of diet, have been, and more than ever now are, the prey of charlatans and sophisti- cated commercial adventurers, A^ho force upon them, willy nilly, whatever fads or fancies of diet yield the fattest sources of profit. As a consequence, the vitality of the race has suflfered. Millions have been robbed of 12 Preface — Continued red blood and the mineral salts so necessary to the building of better brains and bodies. The white spectre of tuberculosis has stalked among them unabashed. Devastating epi- demics have flamed through them like a holo- caust. Diseases having their indubitable ori- gin in malnutrition and poor metabolism ar6 crippling them with rheumatism, arterio-scle- rosis and kidney degeneration. Food, which should nourish and sustain them, has become either a mess of devitalized, innutritions husks, or else an actual source of poison ; and all because Ave have been ill- advised, because we have developed false ap- petites for faulty combinations of food, and because we have been led into a jungle of misconception respecting dietary needs. So, I say, the question of proper nutrition is the most important problem that confronts the race today. Upon its solution depends the health, well-being, and physical and mental efficiency of men and women. If it is true, as I confidently believe, that ninety per cent of all human ailments, apart from disorders incident to old age, or acute infections, are due to wrong combinations and foolish selection of food, then it must neces- sarily follow that the health, longevity and Preface — Continued 13 happiness of the race would be incalculably enhanced if we were rightly to understand and consistently to follow a regimen calcu- lated to prevent further poisoning. It is my purpose in this book to indicate this regimen, and to suggest the means whereby present poisoning may be overcome and future poisoning prevented. In connection with the preparation of this manuscript I have especially to thank Dr. Edwin F. Bowers, who has made the produc- tion of this book possible. He has gone through all that I have written during the past forty years, culled out and brought into align- ment all the material necessary to perfect these chapters. Thanks are extended, also, to my friends and co-workers, Doctors Samuel Lloyd and Henry T. Brooks, for reading over the man- uscript, making corrections, suggestions and additions which have greatly enhanced the value of the work. Furthermore, sincere thanks and apprecia- tion are extended to Doctors Robert T. Morris, Henry O. Marcy, Thomas E. Satter- thwaite, Frank Billings, Reynold Webb Wilcox, Samuel Lloyd, Henry T. Brooks, William A. Dayton, Claude I, Steensen and 14 Preface — Continued Benjamin T, Whitmore for the highly com- mendatory forewords they have written for the book in advance of its pubHcation. They have expressed far more than I ever ex- pected could be said regarding the work. To my publishers, Reilly & Lee, also I ex- tend my sincere thanks for the handsome edition they have produced. I am sure this sentiment will be fully endorsed by every one who reads these pages. The size of the type, and the full interspacing, make perusal excep- tionally easy for tired, over-worked eyes of busy humans these rushing days. William Henry Porter, M. D. INTRODUCTION Nearly seventeen years ago a member of my family developed what several of the most eminent specialists in the East call .interstitial nephritis — a form of Bright's disease. She was anemic and emaciated. The sec- ond sound of the heart was accentuated. For months she had passed large quantities of a low specific gravity urine — 1005 to 1015 — with albumin, hyaline casts, and other kidney debris. There was also a slight tubercular involvement at the apex of the right lung. In spite of, or perhaps because of, a milk, fruit, and " low-protein " diet, and what we fondly and foolishly believed was the best available treatment, she grew weaker, the prognosis became more and more unfavor- able. Then le Bon Dieu, or else the long arm of coincidence, brought me into contact with Professor Porter, at that time Professor of Medicine and Pathology at the Post Graduate Medical School and Hospital of New York. Dr. Porter was, and is, a radical, hewiijg 15 16 INTRODUCTION out for himself, and for the world, innova- tions in medical treatment and in dietetics. One of these innovations had to do with the significance of the presence of indican in the urine. Dr. Porter contends, and this is now gen- erally accepted by really advanced medical men, that when a person has an excessive amount of indican in the urine, the thing from which this person is primarily suffering is autointoxication from the absorption of putrefying intestinal products. Also, that it does not matter particularly just how this self-poisoning expresses itelf, whether in "neurasthenia," rheumatism, ne- phritis, tuberculosis, anemia, or in a predis- position to infectious diseases ; the thing to do, and without delay, is to correct the depraved digestive and metabolic processes responsible for the pathological condition, whatever this may be. This was done in the twenty year ago case of "interstitial nephritis," for the urine, on examination, was found to be loaded with indican, and the ratio of urea and uric acid was decidedly unbalanced. Dr. Porter pro- nounced this a case of intestinal indigestion primarily, complicated with all the hundred INTRODUCTION 17 and one troubles that accompany this most common of all modern disorders. The albumin and casts were present in the urine merely because of mechanical irritation of the kidney cells, due to the action of these putrefactive poisons and their toxic products. All that Dr. Porter did was to correct the intestinal indigestion, by means that will be fully explained in these pages, clear up the putrefactive fermentation in the bowels, and prevent the formation of more indican. In a short time the albumin and casts disap- peared, the general nutrition improved, and the patient got well of everything, and has remained so all these years. The means Dr. Porter adopted for bring- ing about these results were so contradictory to all accepted teachings that they seemed ab- surd. In fact, they are so revolutionary that it is doubtful if even today, except among those physicians who have had the privilege of studying under Dr. Porter, there are five hundred medical men in the United States who would endorse them. ' The idea of keeping fruit away from sick people, and, for the matter of that, from well people also ! And cutting the mild-eyed potato out of the dietary! And putting candy and 18 INTRODUCTION sweets in the Index Expurgatorius ! And of giving red meats in kidney diseases! It does seem absurd. But it "works." Scores of times I have seen the thing proved out, sometimes in very desperate conditions. So I know there can be no question of doubt as to the logic and the efficacy of Dr. Porter's methods. Bright's disease, even in well-advanced stages, clears up. Rheumatism and all the thousand and one symptoms of "neurasthe- nia " are relieved. Tuberculosis, and all sorts and conditions of chronic disease, due to the improper conversion and oxidation of food, fold their dog tents and hie them to more fa- vorable breeding grounds. Only a few years ago, ■ I, myself, had an experience with Dr. Porter's diet and treat- ment that served 'to make me even more enthusiastic about it than I ever had been before. I pass the information along to a few million more middle-aged men who are work- ing at top speed, as I was, and am. When Dr. Porter put the brakes on me I was running a blood pressure of 180, with a fair amount of albumin and numerous hya- line casts in the urine. I followed the diet and the medication here INTRODUCTION 19 outlined, and in three months my blood pres- sure was reduced to 125 — where it has since remained — and for forty-eight years old that's pretty good, and the casts and albumin have entirely cleared up. This treatment any in- telligent person can follow for himself. So I believe, honestly and conscientiously, that Dr. William H. Porter is one of the foremost medical men in all the world — a thinker, a deep student, and a physician whom thousands of grateful patients revere. I be- lieve that the value of his scientific discov- eries, and the incalculable benefits of these discoveries, will accomplish more for the physical regeneration of humanity than any similar work of modern times. I believe that every intelligent man and woman who will consistently follow the sug- gestions Dr. Porter has here outlined, will have ample cause to congratulate themselves three hundred and sixty-five days in every year for the remainder of their lives. Edwin F. Bowers, M. D. Eating to Live Long CHAPTER I THE WHY AND THE HOW OF FOOD Shakespeare once said: " We are such stufif as dreams are made on; and our little life is rounded with a sleep." This is splendid poetry, but like a lot of other poetry it has in it considerable license and mighty little com- mon sense. The real fact is that we are made up en- tirely of the " stufif " we eat and the water we drink, plus the oxidizing or reducing action of the air we ^^^^ q^* ^^ breathe, and the God-given force — whatever that may be — that starts the life processes into motion and keeps them going. So definite is this relation between food and the organism that feeds upon it that, among those whose opinion carries weight, it has be- come an accepted axiom that the organism itself is a very excellent index of the qualit)^ and quantity of material that has entered into the nourishment of that organism. 21 22 EATING TO LIVE LONG One need not be a professional farmer to know that if a plant is supplied with plenty of 'n II n/r Tiri. .. Hianure, from which it can ex- Tell Me What ' You Eat and tract the nitrogen necessary for I'll Tell You its growth, this plant will grow to twice the height and develop twice the food value of that of a plant deprived of fertilizer. This is especially true if phos- phorus also is added as a fertilizing agent. The same nutritional need is observed also in all animals raised for food purposes, or any other purpose. Man, who is merely a rather refined — in some cases, not very refined — type of animal, is subject to identically the same law of growth. When the nourishment is poor and scanty, man is stunted, mentally and physically. His resisting powers are lowered; he falls more readily victim to devastating diseases; and he indubitably has a shorter and a more unhappy existence — provided he has sense enough to appreciate the grim joke Nature is playing on him. So we eat to build tissue, to acquire and retain the ability to withstand the ceaseless attacks of microorganisms, to develop better brains, and to absorb nutritive salts — prin- THE WHY AND HOW OF FOOD 23 cipally phosphorus and lime — lacking which, life cannot be adequately sustained. In addition to these nutritive salts our food also furnishes us with medicine — iodine, iron, and various salts and acids — indispensable to correct function- q°^ Medicine ing of our bodies. So that one who nourishes himself with properly selected foods can maintain such a state of health as to make himself relatively independent of doctors or the drug store. Not infrequently even the services of the undertaker may be deferred until a much later period. Racial as well as individual physical and mental characteristics are also developed by diet. For instance, nations nour- „ _, , ' . How Food ished on a diet rich in nitrogenous Affects Our elements — those elements that ^'^^ ^"<* build tissue — as well as a suffi- cient quantity of the other food-stuffs neces- sary to round out a balanced ration, are characteristically well developed. And they look it. When, however, an exclusive meat diet is depended upon for nutriment, as with the Eskimos, for example, the result usually man- ifests itself in a stunted, squatty growth. 24 EATING TO LIVE LONG This hindered growth is not due to the influ- ence of cold, as many claim. For even in tropical Africa there are several tribes of dwarfs, including the Batwa and the Wam- buti, who, like the Eskimos, feed almost en- tirely upon meat. And they are quite as stunted as the Eskimos, or even more so. The explanation of this lies probably in the fact that in persons living largely upon a meat diet, a definite influence is exerted upon the thyroid and sexual glands, as well as on the pituitary body in the base of the brain — those organs that definitely regulate bodily growth. Certain of these organs influence the metabolism of phosphorus and lime, the chief elements that go to make up the bony structure; for we know that where the de- velopment of those organs is abnormally hin- dered, growth is restricted. The influence of food upon physical develop- ment is cumulative, which also would account for the increased growth in nations that have conquered or bartered their way to a better food supply than others. It accounts also for •the stunting and malnutrition apparent among the children of the poor, who have been chron- ically under-fed from their grandfathers' time down. THE WHY AND HOW OF FOOD 25 If we would thrive, our food must be "bal- anced." It must contain albumin, as well as starch, sugar and fat. If we get too little animal albumin — that in- °°°^ ^'^^ ^ad dispensable "building stone" of what They Do body cells — the result is a lean and hungry aspect that does not accord well with a physician's idea of pulchritude, how- ever well it may fit the commonly accepted notion of beauty. This explains why the Hindoos, who live chiefly upon rice and mil- let, are animated demonstrations of the human frame divine. And also why the Japanese, Malays and Chinese — with the exception of the Manchus, who live upon a somewhat richer diet — are usually spare as to flesh and overly prominent as to bone. Vegetarians as a class are almost inva- riably lean, and almost invariably ailing in some respect. This may not arouse volleys of ringing cheers The r i. • r • J Vegetarian from our vegetarian friends. Grouch Nevertheless, I have yet to see a strict vegetarian — not a vegetarian who lives upon milk, eggs, butter, but a real Simon- pure, herbivorous vegetarian — who did not have something the matter with him, even if it was only a chronic grouch. 26 EATING TO LIVE LONG This inevitably is produced by the inabiHty of the system to oxidize the kind of stuff the vegetarian mistakenly takes as food. Every animal tamer knows that in bringing up young animals not entirely carnivorous in nature, the less meat they get, Too Much^* ^^^ more docile they become. To Meat a certain extent, this is also true of the human. Yet there is a happy medium between the bovinely placid Chinaman or Hindoo kind of person and the Spartan or Martian disposition brought about in the war-like races by a diet of bloody soups, meat and milk. However, a proper amount of albumin, which is the most certain of all energizers, is absolutely necessary, either for a conquer- ing race or a conquering man. Nor is the effect of a liberal diet more marked upon the body than it is upon the mind. No intelligent person who Seine for ^^^ "^^ed the results of experi- the Memory ments made upon thousands of under-nourished school children in various schools throughout the country, can have failed to be struck by the marvelous progress made by these .little brains after the THE WHY AND HOW OF FOOD 27 bodies and blood that feed them were prop- erly fed. "Backward" children were found to be merely brain-starved children. The dunce was only a bright boy who hadn't had any breakfast; the incorrigible, a poor little chap who is a victim of the society, or the cir- cumstances, or the neglect that prevents him from getting proper nourishment. We now know, and we have proved it on a tremendous scale, that it pays, in actual dollars and cents, for the municipality to shorten the school period by anywhere from one to three years, merely by increasing the food supply of its school-children. Food feeds brains as certainly as books, or in some instances, even more certainly. It is to be hoped that the muddle-minded school boards^ who comprehend the utility of a thing about seventy-five years after everybody else on earth re- ^'P Van .. .^ -^ :. ,. .„ ^ , Winkle School alizes Its application, will take Boards this invaluable object lesson to heart; and that they will make it possible, no matter how, for every school child in this land to put something hot in his stomach before any attempt is made to put something cold in his brain. For a functioning memory 28 EA TING TO LIVE LONG and an empty stomach are incompatibles. Much sentimental balderdash has been per- petrated concerning the marvelous intellectual and artistic achievements of the The Hungry garret-grown geniuses, the nat- ural inference being that the more empty the stomach, the more brilliant the evidence of his genius. The truth of the matter is* that the Chat- tertons and the Ole Bulls achieved their measure of success in spite of and not be- cause of their poverty and parsimony of fare. Perhaps Carlyle, who was forced almost all his life to live in a chronic condition of semistarvation, might have been another Plato if he had not been perpetually under- nourished by oatmeal, and poisoned by the fermentation products of this worst of all so-called "foods." The great advances of science and inven- tion have been, in the main, achieved by those XT ^1. . races or peoples who have con- No Chance to , . . Be Scientific sumed a fair amount of albumin, on a Diet of The vegetarian races may have developed wonderfully in con- templative and philosophical pursuits, but the great discoveries in all those fields that ad- vance science, and engineering, and the things THE WHY AND HOW OF FOOD 29 that make modern life worth while, originate among the albumin-consuming — particularly the meat-albumin eating — races. For what is generally ignored or else not understood, even by specialists in dietetics, is the fact that vegetable proteids, owing to their more com- plex molecular structure, are less easily pep- tonized in the stomach than the simple mole- cule of the meat structure. Consequently, the vegetable diet imposes more- work on the intestinal ferments. And the more work the digestive organs have to do, the less energy remains for any other kind of work. Wit- ness the cow, for example. With vegetable foods from fifteen to eighty per cent of the proteid is lost as it passes through the alimentary canal in an undigested state, because of the fact that the proteid molecule, as it is found in the vegetable king- dom, is very difficult to reduce to its simple form, the only form in which the system is capable of utilizing it. On the other hand the animal proteid has already been redjiced from its complex to a simple construction. Therefore, The Animal according to the law of isom- Proteid is 1-c ^- r ^-u Already a ensm, or simphncation oi the simple food unit, it is easily transformed Molecule 30 EATING TO LIVE LONG by the digestive ferments into a readily as- similable form. Nor is the superiority of the meat-eating races a question of favorable climatic condi- tions, .as many contend. For the It's the Food, climate of Japan and China is Climate approximately the same as the climate of Europe and the United States. Yet, the really ingenious things, such as the gr^at medical discoveries that have enriched the world and lengthened human life, as well as the great discoveries of wholesale killing that impoverish the world and shorten human lives, are evolved by the races whose diet is rich in easily assimilated nitrogen. The chief elements of nourishment for nerve and brain — phosphorus and lecithin, or nerve- fat — come largely from Si'sSr meats, fish, eggs and milk. These by Eating elements are indispensable for building and maintaining the cen- tral nervous system. With a rice and vegetable diet, however, very little of these elements is absorbed, as even the rice, the coating of which contains a fair amount of phosphorus, is usually eaten by rtiost of the Oriental races with the husk removed. THE, WHY AND HOW OF FOOD 31 The lack of these essential elements in the diet not o'nly starves the brain and nerve sub- stance, but it also induces grave disorders in the thyroid and other glands which have a profound effect upon the metabolism of lime and phosphorus compounds. These, in turn, cause beri-beri, Basedow's disease, and other grave disorders of the nervous system. So if we are to supply our body and nerve- cells with foods capable of sustaining a com- petent functioning condition, we are obliged to provide them with nuclein — rich meat, fish and eggs — so as properly to stimulate the organ which regulates the use of phosphorus in our bodies and brains. It is also a matter of common knowledge that if we want to keep an individual in a cheerful frame of mind, we must feed him food. He may possibly ^^^^"^"^ be kept alive for a while on Knows "health foods" and other fodder; but he will not be nearly so gentle and com- placent ; and a hungry man is an irritable man. Wise women discovered this fact back in the Neanderthal days, and their female de- scendants today practice the adroit art quite universally. For exactly the same adequate feeding methods that cause a cat to purr will 32 EATING TO LIVE LONG cause a man to purr. Thus the sum total of human happiness is increased by proper food, and correspondingly decreased by improper food. CHAPTER II TURNING FOOD INTO FUEL AND REPAIR STUFF Every move we make, every thought we think, every infinitesimal sparkle in our glad eyes, uses up a definite amount of energy and destroys a definite, even though microscopic, amount of cell structure. There is only one way in which this loss in energy and sub- stance can be replaced, and that is by con- verting food into more energy and more cell structure. At first glance this would seem to be simplicity itself, especially in view of the fact that the human race has been prac- ticing feeding for half a million years. Yet nothing, so far as most experience goes, seems to be more difficult. The trouble, thus far, lies in a basic miscon- _, .. ' ^ The Merry ception as to food values as re- Art of Eating lated to digestive processes, to- Wisely and gether with a ridiculous worship of the Great God Calorie and all his functions and attributes. 33 34 EATING TO LIVE LONG Were it not for these misconceptions we probably would have to subsidize old Malthus to lie quiet in his grave while we developed sense enough to cope with the supply and demand problems of human beings and their food. On the foundation of this general igno- rance of food and food values we have built a Colossus to Ill-Health, into the ^"\^i"S 111- Moloch maws of which we yearly Health Out of -^ -^ Wrong Food feed millions of valuable lives, and countless millions of hours of inefficiency. For upon the kind of food we eat and the combination of these kinds of food, and upon how thoroughly we get rid of what is not utilized, depends about ninety per cent of our physical well-being. The fact that we do not know these things accounts for why so many of us are crawling, half dead, between the legs of the Colossus — r crippled with "rheumatism," with degenera- tive diseases of the heart and blood-vessels, or with grave disorders of the digestive ap- paratus, or of the organs of elimination. Yet the problem is simple enough. It consists merely of giving a completely balanced diet in proper amounts, and of getting rid of the debris. TURNING FOOD INTO FUEL 35 As to just what constitutes a "balanced diet" there is need of some httle figuring, although not as much as one would suppose; at least, not for „g f^ ^^ humans living in this climate and Diet"? under the forms of civilization with which we happen to be familiar. The problem is, to combine the three great classes of food — water and the inorganic salts ; starch, sugar and fat ; and the proteid group — so that the salts and proteids, together with the vitamines and enzymes, may properly build and effectively replace waste tissues; while the starch, sugar and fat furnish heat and force without burning out the lining of the physiological boilers or rusting the flues, which is what many of us very effectively now do every time we eat. All varieties of food are important; but the proteids are the most important, not only for the work they accomplish, but also for the potentialities for harm that are wrapped up in The Value them if their debris — their or- ^ Proteids ganic ashes and clinkers — are not removed from the alimentary firebox after their parent forms have done their bit. For the proteids are the undisputed 36 EATING TO LIVE LONG champions of the body's poison squad. This does not mean that they should be eHminated or even curtailed, but only that they should be thoroughly digested; and the most certain way to insure their proper digestion is to take them in their most digestible form — ^meat (preferably beef), eggs and milk. Only 2.8% of beef is lost in its passage through the alimentary canal; 2.9% of eggs, and 5.7% of milk; as against 80% of the protein of oats, for instance, which passes undigested through the alimentary tube of the sturdy Scot, filling him full of the gases of fermentation the while. The same ease of digestion holds true for all the animal foods, but the three here mentioned are the best for practical utility. Starches and sugars are also important food elements, although not needed in any- thing like the amounts we have Starches fatuously thought necessary. In 3S AClu Generators fact, the excessive use of these items is the head and front of all food offenses against the citadel of Good Health, either because of the excessive quan- tity of pathological acids they may generate, or because of their tendency to rob the pro- teid foods of the oxygen necessary for the TURNING FOOD INTO FUEL 37 complete conversion and reduction of the proteid "end-products." Lastly, fats are essential up to the limit of the ability of the secretions of the liver and intestinal glands to transform them into a fine emulsion for absorption into the lacteals. This is applicable especially to animal fats, Mobile the vegetable fats are converted by the secretions of the liver and pancreatic glands into glycerine and soap before they are util- ized for body needs. These, in conjunction with the bile acids, constitute Nature's natural laxative, without which there is constipation. The processes by which these various groups of foods are transformed into the material finally used for building and running the body are among ^°^^ l°fp^^i the most intricate and complex the Body known to science. The manifold secretions act and react upon one another and upon the food substances that are under- going the changes necessary to fit them for assimilation and final metabolism. Reasonably thorough mastication is neces- sary to enable the saliva to act upon the starches ; for the ferment of the Do Not Forget saliva, ptyalin, plays a highly ^^^^^^^ ^^^ important part in the digestion No Teeth 38 EATING TO LIVE LONG of starches, converting them into sugar, or maltose, which later is converted into glucose, the form in which it passes through the intes- tinal wall, and the only form in which starch can be utilized in the body. Of course, the saliva acts also as a lubricant, facilitating swal- lowing of the food boluses. Saliva has also another important function ; for when it reaches the stomach its alkalinity excites the flow of the gastric How Alkaline gecretion. This action is pro- Saliva Excites ^ the Secretion duced accordmg to the common of Acid law that alkalies, brought into contact with acid-secreting mem- branes (such as are the stomach membranes), tend to stimulate the flow of acid secretions; while acids brought into contact with acid- secreting membranes tend to decrease the flow of the acid secretion. The reverse of this law is true of the alkaline-secreting membranes. So if we wish to maintain a reverent care for our digestions, our food should be thor- oughly masticated, and in as dry ''° ^?^*"f . a state as is compatible with com- andNoWash- .... ing-Down fort and the discrimmatmg sense of taste; for only by this means is the largest amount of alkaline saliva se- TURNING FOOD INTO FUEL 39 creted, and this, as we already have seen, is an important factor in exciting the gastric flow. The next step in the digestive process is produced by the action of the hydrochloric acid in the stomach — that big water-bottle of muscle, the chief J?°T' *^^, . . ' . Hydrochloric function of which is to mix and Acid Works churn the food into forms which facilitate the digestive processes. The hydro- chloric acid, which is the true acid secretion of the gastric juice, attacks all forms of al- buminous and nitrogenous compounds, whether derived from vegetable or animal sources, and changes them from their native state into an acid albumin, commonly called syntonin. The reason for this change is that the pepsin can operate best only on an acid albumin. For its perfect action it requires an acid medium. The pepsin produces a gradual and peculiar gelatinization, in which the semisolid syntonin is transformed, first, into what is known as a "pro-peptone," then into albumoses, and finally into a liquid and readily diffused peptone, which is the only form in which albumin is taken up into the body. It is estimated that twenty-five to thirty-five per cent of the substances pep- 40 EATING TO LIVE LONG tonized in the stomach may be absorbed by the stomach. It is important to remember, however, that the peptonizing action of the stomach is a slow and comparatively weak But the J ^ i/ 1 Stomach Acid process, and as a result only a Does Only small portion of the albumin is Work' * * completely transformed in the stomach into a diffusible peptone. The starches, sugars and fats, practically speaking, are but little affected by the di- gestive juices of the stomach, although the nitrogenous envelope surrounding the starch granule or the fat globule may be digested away, thus setting free the granulose and the oil. This process has been called "the starch-hydrating and fat-freeing action of the stomach." After the food has been churned around by the muscular contractions of the walls of the stomach for a sufficient When the length of time, varying with the Stomach Gets , ^ . ^ , , i , , Through character of food taken and the physical character of the in- dividual digesting the food, it is passed through the lower opening of the stomach — the pylorus — into the small intestine, where the really important work of digestion is car- TURNING FOOD INTO FUEL 41 ried forward. Then, through a most com- pHcated process of action and interaction of the secretions and ferments, such as prose- creti*^, secretin, prokinase, trypsin, erepsin, and a number of other digestive agents, the digestion of the albumin is carried on to the production of its end-products, the "amino acids." Meanwhile, the pancreatic ferment, amy- lopsin, and the secretion of the liver — the bile — are busy with the sugars and starches. They change them into maltose, and get them ready for their final conversion by the in- testinal fluids into grape-sugar (dextrose), m which form alone they are capable of being taken up by the system. Here, it is currently taught, they are stored in the liver in the form of glycogen, and subsequently burned in the muscles as fuel. This, however, is contrary to the facts and well-known laws of chemistry. This theory I believe to be untenable, for the simple reason that, in removing the liver for examination, unless that or- gan is extracted from the body Glycogen is with lightning-like rapidity, all ^Y^^ lj^^j, the glycogen has vanished. It is much more likely that the glucose is con- 42 EATING TO LIVE LONG verted into various isomeric antecedent prod- ucts, varying in kind and quality, but ulti- mately being oxidized directly into carbonic acid and water. Because glycogen occasionally has been found in the liver, it has been looked upon as a "stored-up" product. Much if not all of the glycogen produced in the system, however, is derived from oxidation reduction of the nitrog- enous products — from the albumin. When oxidation is incomplete it passes as glycogen, or some other form of antecedent product, to the kidneys, where it is seized by the kidney cells and discharged in the urine, giving rise to the condition known as glycosuria or diabetes. The fats are acted upon by the pancreatic juice, the bile and certain secretions of the intestinal glands; first, to be Turning Fat changed into a fluid, in which the Food Soap steapsin of the pancreas can be more readily separated into fatty acid and glycerine. This glycerine is soluble. The fatty acid is acted upon by the bile salts and various alkaline compounds in the intes- tines, which give off a certain amount of soda, and changed into soap, by the well-known action of alkalies on fats. So fat merely un.- TURNING FOOD INTO FUEL 43 dergoes a process of subdivision, the fat globules being split into such fineness that the little villi — the fleshy pumps on the in- side of the intestinal walls — can pump the emulsified fluid out of the lymph spaces and finally carry it into the general circulation. The animal fats are most easily emulsified, hence more easily utilized as heat and energy producers. On the other hand the vegetable fats are more easily split into a fatty acid and glycerine. Hence they are more apt to be laxative in their action. This, in very sketchy form, is the method by which food-stuff is converted into nutri- ment and fuel. If the process were a perfect one, and if the debris and the utilized products could be completely burned up, or eliminated through the avenues of excretion, the phy- sician's occupation would be as defunct as was Othello's; but the functions fail of theo- retical perfection. Hence the mutability of human existence. CHAPTER III GETTING RID OF THE ASH AND CLINKER It is a matter of common knowledge that if a fire is to burn freely the furnace must be kept reasonably clear of ashes and clinkers; otherwise the draught is impaired and com- plete combustion is prevented. It is just the same, or more so, with the human firebox, the alimentary canal. For if this is clogged it not only impedes the functions of digestion and assimilation, but the material that im- pedes these functions decomposes and forms products that still further hamper, not only the digestive apparatus, but also the nervous system, and every organ and structure in the body. Accumulation of these waste products in the system is one of the most certain of all means of lowering vitality and How Food ^jjg normal resistance to disease ; Toxins Lower .

Perhaps the head and front of all offenses against the body's vulnerability are chronic constipation and the putrefactive Constipation fermentation that accompanies it ; Much Trouble ^^^' the toxic putrefactive prod- ucts generated by decornposition of food substances in the intestines are ab- sorbed through the intestinal walls into the blood stream, there to depress every function of the body and still further to continue the causes that first developed them. Bowel surfaces that should be clear for the absorption of food products become caked over with a thick tenacious mucus in which the putrefaction bacteria produce toxic mate- rial, from which deadly organic poisons — indol, skatol, indoxyl, and other ptomaines — ahe derived. Kidney troubles, characterized by the void- ing of large amounts of low specific-gravity urine, containing albumin and Kidney Dis- , ,• , ■, ease a Lineal hyaline, granular and waxy casts, Descendant of also have their origin in intestinal Bowd"^^""^ fermentation; for the sluggard bowel, by shifting a considerable portion of its work of elimination upon the 46 EATING TO LIVE LONG kidneys, overworks these organs. The nephri- tis that develops is merely an expression of resentment on the part of the kidney against this overwork. Diabetes, also, is a frequent result of this same grave fundamental cause — the absorp- tion of toxins that paralyze the normal func- tioning of the gland. These arise, in large measure, from overeating, eating the wrong kinds of food, and from failing to rid the system of the accumulated debris. The successful treatment of these conditions does not depend so much upon stimulating the action of the liver, kidneys or the pancreas, or in whipping them to do their duty, as it de- pends upon seeing that the bowels do their full share in sifting out the slag and refuse. Many diseases that affect the liver develop because that overworked organ has to shoul- der the extra burden of neutral- STbused"'' i^^"g ^"d filtering out of the blood poisons which never should have been permitted to enter it. Rheumatism, biliousness, an overworked liver — commonly called torpid — congestion and enlargement of the gland, and even grave degenerations of the organ, are a frequent result of this overwork. GETTING RID OF THE ASH 47 Of all the agents tending to rid the system of organic debris, the liver, through the bile, is perhaps the most important, Liflslver although the laxative effect of fats also has a prominent action. Yet the laxative effect of the fats is dependent upon the quantity and quality of the bile salts and the steapsin; so *^hat, in the final analysis, it is the function of the liver which is of first importance in regulating intestinal peristalsis. For this reason, when bile is defectively produced by the system the addition of new bile is in keeping with the demands of Nature and the principles of strict common sense. This bile can best be supplied by administering dried ox-gall, from two to five grains in cap- sules, preferably in combination with a few grains of pancreatic extract, three to four times a day, just before eating. In addition it might also be well to stimulate the bile-secreting activity of the liver by ad- „ , ... ministering from ten to fifteen Hydrochloric ° Acid the drops of dilute hydrochloric acid Natural Livfer after each meal. Hydrochloric acid, which is the normal stomach acid, is one of the best of all agents for toning up the normal activity of the liver, to say 48 EATING TO LIVE LONG nothing of its splendid effects on almost all forms of chronic digestive troubles, especially •if these troubles have their origin in a lack of secreting power on. the part of the stomach glands, or in a sluggish condition of the liver. There is hardly anything quite so definite and uniform — unless it be increasing prices and income tax — as the beneficial results of this simple treatment, in combination with the rational regulation of the diet, which wi]l be described in a later chapter. It should also be remembered that the biliary fluid, once in the alimentary canal, pre- vents putrefactive decomposition of the intestinal contents and aids ?''* ^f ^" . . Intestinal m perfectmg digestive metabo- Antiseptic lism. The bile may therefore be looked upon as Nature's chief internal anti- septic, as well as an indispensable digestant. This assertion is sustained by the rapidity with which decomposition in the intestine occurs whenever the secretion of bile is impaired, arrested, or changed in quality. So when the old bile, or bile of poor quality, is expelled from the system and its place taken by new bile of better quality, digestion, as- similation and elimination are immediately improved and nutrition progresses normally. GETTING RID OF THE ASH 49 This is conclusively proved by the fact that the products of nitrogenous oxidation found in the urine are rapidly changed from an ex- cess of uric acid, oxalates, lactates, and urates — even sugar and albumin — into products of normal digestion and oxidation, in normal percentage and quantity. Nor must w^e forget the solvent action of copious w^ater drinking between meals as a povi^erful aid to removing ac- Water Also cumulated ash and clinker from Helps to Solve the Problem the System. Water, passing as it does almost immediately into the intestinal canal, helps to facilitate removal of the debris from the bowels ; first, by rendering their contents more fluid; and second, by the stimulating action it exercises on the peris- taltic muscles themselves. It is quite certain that ten or a dozen glasses of cool — not iced — 'Water, drunk daily, would do more to re- move digestive troubles, as they affect the American public, than perhaps any other one measure that could be recommended.

Yet it is a fact We Do Not that men and women, many of See the Obvi- , , , . i i- ,• ,• ous Things whom have achieved distmction in business, intellectual or social life, do consistently and persistently ignore them. Which is the chief reason why under- taking remains one of the most profitable pro- fessions that wide-awake men can possibly engage in. CHAPTER IV STARVING ON A ONE-SIDED DIET On April 11th, 1915, the converted cruiser Kronprinz Wilhelm, after one of the most sensational privateering expeditions in marine warfare, slipped into the James River, off Newport News. Her crew was stricken with a disease which the doctors pronounced beri- beri, although they might just as well have called it scurvy, or pellagra, or jail edema, or neuritis, or "trench fever" — all of which manifest similar symptoms. One hundred and ten of these privateers were incapacitated. All the others were on the verge of a physical breakdown. This was why the commander of the Kronprins Wil- helm took the desperate chance of running into port. The officers and marines aboard the war- vessel had been living on a diet of fresh meat, white bread, soda crackers and fancy cakes, sugar, cheese, eggs, ham, bacon, condensed milk, oatmeal, degerminated corn, oled, boiled 52 ONE-SIDED DIET 53 potatoes and cofifee — food that millions of Americans fatuously believe contains all the nutrient material necessary to sustain health and life, and which any number of them, no doubt, will continue to believe contains all the nutrient material necessary to sustain life. The Kronprins doctors and crew did not know, any more than do these millions of Americans know, that they had been living upon a diet deficient in a balance of acid and base-forming elements in the "ash" content of their food. They were not aware that they had been subsisting upon food the base-forming ele- ments of which had all been Living on "processed" out; and that, as a FoodleSS - rr • Foods consequence, they were suffermg from acidosis, which caused the extraction of lime salts from the muscles, fibrous tissues, nerve-cells, cartilages and bones. They failed to realize that the deficiency of lime salts in their diet leads to weakness and irritability of the muscles, with neuralgic pain, as well as eflfusion into the joints, and the consequent painful swelling of these joints, which finally resulted in thinning and eroding their cartilages. 54 EATING TO LIVE LONG They little recked that the failure to sup- ply lime salts in adequate amounts is a pro- lific cause of the tuberculosis which many of them were beginning to develop. These Kronpriuz victims were consuming huge quantities of "refined" foods, deficient in life-giving lime and potassium salts and iron. They were getting no fresh vegetables, whole wheat, or any other food that would supply them with these necessary salts. Even the water they drank was deficient in lime or other salts. For it was produced by a process of distillation from sea _ ^^ . water, the effect of which was Drinking still further to abstract from the Water Was tissues themselves more, and ever ^'"*"*'' ^^ more, of the precious calcium salts that should go to nourish cell structures.

Got Their Any active "food expert" could "Calories" have estimated that they were ^" ^'^'*' getting all they required, and more than they required, in calories of food value to keep them in the very pink of physical condition. Yet this crew developed typical symptoms of ONE-SIDED DIET 55 paralysis, atrophy of the muscles, inflamma- tion of the nerves, dilated hearts, edema, and anemia. The ship doctors, and the consultants they engaged as soon as the vessel came to port, agreed that the cause of the trouble was pol- ished rice; notwithstanding the fact that the Kronprinz crew ate rice only once a week, or one meal out of twenty-one. Finally Professor Alfred McCann, who has been one of the most valiant contenders for rationalism in diet, suggested to How the Dr. E. Perrenon, the ship's chief- "Beri-Beri" , , ^ ^ Was Banished surgeon, that the men were suf- fering from mineral salt and vitamine starvation, and that the rational treatment for their condition was to feed them mineral salts and vitamines in their diet. It was so ordered. Wheat bran, whole wheat bread, carrots, parsnips, turnips, onions, spinach, beets, cauliflower, string beans, aspar- agus, lettuce and other forms of salad, fresh vegetable soup, the yolks of eggs, unskimmed milk, orange and lemon juice and limes, were given with a liberal hand. Alkaline waters were freely administered, to increase body alkalinity and help neutralize the acid end-products of the meat and white 56 EATING TO LIVE LONG flour diet. Best of all is liquor calcis et sodii phosphatis compositus. It has the following composition per hundred parts of water: So- dium carbonate (Na2C03), 00.404; sodium phosphate (NaaHPOO, 00.023; sodium chloride (NaCl), 00.080; calcium carbonate (CaCOs), 00.057; magnesium carbonate (MgCOs), 00.004; potassium chloride (KCl), 00.004. The result was that in ten days forty-seven sick men were returned to duty, and in a few brief weeks every single member of the crew had recovered. Even those who were paralyzed regained considerable of normal function. The moral of the story is that wrong food is the cause of grave pathological changes in the structure and functions of the body; and that the ravages of 1^^^°^^^^ tuberculosis, 'nervous disease, malnutrition, and the lowered vitality that in- evitably leads to grave disorders, can be over- come — by proper feeding. It is as simple as A B C. But will the American public, and the public of the world, be allowed by the altruistic manufacturers of demineralized food to learn the lesson? A deterioration in the physical state may be brought about by feeding a diet consisting ONE-SIDED DIET 57 Proper Nutri- exclusively of meat, or entirely tion Demands of vegetables, or a regimen lack- More Than jng in fats, sugars or starches. This is frequently noticed as a result, for instance, of the starch and fat-free diet sometimes injudiciously resorted to in the treatment of obesity. On a diet consisting almost exclusively of meat a patient w^ill become much thinner. But while he is doing so he not infrequently will develop various unpleasant symptoms, such as faintness, fatigue, a tendency to perspire on the slightest exertion, nervous excitability, con- stipation and various functional conditions. A one-sided diet of this nature will invari- ably bring about a diminution in the amount Ptoteid Alone "^ albumin in t-he body. This Will Not loss of bodily albumin may often Replace ^g fraught with grave conse- ^Ibumin Loss r i quences, for when excessive quan- tities of meat are taken without the addition of starches and fats it is not possible to main- tain the nitrogen balance. In a diabetic patient there will frequently be an aggravation of the condition, as well as the formation of acetone bodies, so that very fre- quently such patients die in coma, owing to acid poisoning. 58 EATING TO LIVE LONG On the other hand, when an occasional baked potato, or some other carbohydrate is added to the diet, immediate improvement will be manifested. An exclusive starchy diet may give rise to equally bad results. For when starches and suears are taken in excessive . . • 1 r • An Exclusive quantities, acid fermentation vegetarian takes place in the intestine, and Diet Just as bowel peristalsis is greatly in- J^^-'^i^'*'' creased. As a consequence, food is eliminated from the body too soon for the intestinal canal to absorb the nutritional elements, and emacia- tion will result. Those who are required to depend largely upon carbohydrates — on rice, for example, as do the poor Chinamen and Hindoos — are usually, for this reason, very thin. With vegetarian faddists, who attempt to live upon a purely vegetable diet, the same emaciation, and the anemia that almost always accompanies it, is observed. When albumin is deficient, which it always is in a vegetarian diet, much more fat is re- quired. This fact, however, is generally ig- nored by vegetarians. Anyone who lives upon plant food exclu- ONE-SIDED DIET 59 sively eliminates unused a much higher per- What At centage of his nutrient material Found Out than one who combines his vege- About Vege- tables with a little meat. table Foods a , . Atwater, expenmentmg upon himself, found that on a purely vegetarian diet 28.26% of the nitrogen substance of the food was passed in the feces. When, however, a moderate amount of ani- mal food "was added, the assimilation of food substances was markedly improved, only 11.59% being lost. With an adequate amount of animal food added to his dietary only 8.88% was lost. No competent physiologist now doubts that it is impossible to retain the nitrogen balance of the body with an exclusive vegetable diet. These are conclusions that might well give the hardiest and most determined vegetarian pause — if he be not blinded to scientific values by what amounts almost to a frenzy of fanaticism. So between those who deliberately starve us for profit, and those who foolishly starve themselves, because they are convinced they are benefited, the physical status of our peo- ple is suffering greatly. Nothing short of drastic legislation on the one hand, and copi- 60 EATING TO LIVE LONG ous doses of education on the other, will ever work the revolution that is necessary if we are not to go from a decided bad to an in- finitely more obvious worse. CHAPTER V MINERAL SALTS AND VITAMINES It was in 1911 that Dr. Max Moszkowski, a German physician, succeeded in giving himself an unmistakable case of beri-beri by living for one hundred and thirty-eight days upon a diet which consisted almost exclusively of hulled rice. After indulging in this rice debauch a few weeks the nervous symptoms accompanying beri-beri — practically identical with those that later affected the ?''^^^" J*^"^* to Order by crew of the Kronprins Wilhelm Wrong Food — manifested themselves. The characteristic dropsical affection of the skin, followed by soreness of certain groups of muscles, stomachic disturbances, loss of functioning power in the muscles of the legs, and finally, the typical and dangerous irregu- larities of the heart action, left no doubt as to the nature of the disease. It was identical in its character with the condition that had been experimentally pro- duced in fowls and pigeons by feeding them 6^ 62 EATING TO LIVE LONG polished rice; which condition terminated in- variably in the paralysis and death of the birds when the feeding of the demineralized rice was persisted in. However, exactly as in the case of the fowls and pigeons that were cured with rice hulls, Dr. Moszkowski eliminated from „. * , * , his system all evidences of beri- Kidiculously . •' Easy beri by injections of an extract prepared from rice hulls. His recovery was rapid and complete, and he sub- sequently remained absolutely well. The medical officers in the Japanese navy also found by experiment that the polished rice which composed a consider- The Japs Also ^y^ ^ ^j ^^^ ^j^^ ^f ^j^ j^. jj_ Know How to ^ Cure Beri-Beri ors, caused the polyneuritis, or beri-beri, from which their crews suffered. This was checked at once, merely by feeding whole brown rice, instead of nice, shiny, polished rice. This discovery was applied to the epidemics of the disease which were ravaging our Philip- pine possessions, with the result that beri-beri is now another of the long list of diseases that have been finally conquered by the ingenuity of man. These experiments proved conclusively that, MINERAL SALTS, VITAMINES 63 in addition to their phosphorous content, there is in the hull and husks of grains a substance that exercises a profound eflfect upon the well- being of the organism. But "prison edema" still remains; tea and toast and tuberculosis still make up a trio whose power for evil is tremen- ^ ^ dously potent; rickets, malnutri- Haven't tion, chalky teeth, and extra sus- Learned Our ceptibility to disease, are still evident among a vast number of our popula- tion. Even among our country people, who send the best food they raise to the city, and eat the remainder, evidences of malnutrition are common. Why ? It's because they ignore the fact that in the bran, or outer covering of our grain foods, and in the skins and the germ of j^^ . , cereals, there exist substances — Mineral Salts for there are probably many ^^^ Vitamines varieties of them — the adminis- tration of which influences in some mysterious way the digestion and metabolism of food, and the lack of which predisposes to grave organic disorders. Casimir Funk, who first brought the hypoth- esis into general recognition among scientific 64 EATING TO LIVE LONG men, called these substances " vitamines," from " amin," a chemical compound, and "vita," life. Funk considered the cause of beri-beri, pellagra, scurvy and rickets to be the lack of substances, each of which manifested specific results, determining by its absence the nature of the disease. Ordinary brew^ers' yeast is loaded with this material, which has been isolated, and dried in a solution of clay, in which hJ°Yea^I:'"*"'^ form it is conveniently kept for any reasonable length of time and quite readily administered. Fowls that are moribund with polyneuritis almost invariably respond at once to the administration of this material, and recover within a very short time. But equally good effects, although perhaps not so rapid in action, can be obtained by eat- ing wheat bran, or the germ of corn or other grains; or by drinking milk, or partaking of other material, such as spinach, collards, tur- nips, cabbage, butter fat, or egg yolk rich in mineral salts and in these life-giving principles. In this connection the experiments of Dr. E. N. McCollum, of the School of Hygiene MINERAL SALTS, VITAMINES 65 and Public Health at Johns Hop- kins University, have a peculiar How Dr. . r McCollum Significance. Killed Rats Dr. McCollum proved, in a series of experiments with fifteen thousand rats, that the rodents will starve — and it may be inferred that men, treated the same way, would also starve — if fed on a diet of Indian corn alone. On corn and olive oil the rats did a little better. But with the addition of greens of some kind they thrived, waxed fat, and multiplied. We now know that this is because the greens, as well as the outer layers of cereals, contain a substance — probably some form of vitamine, although McCollum objected to the term " vitamine," because it was, chem- ically speaking, misleading and inaccurate — which furnishes some indispensable stimulus by which the system is enabled to transform certain food substances into tissue. This substance Dr. McCollum called " water soluble B." The " fat soluble A " — also iso- lated by Dr. McCollum — which is found in butter fat, cream, and other animal fats, but which, curiously enough, is not present in vegetable oils, is also a vitalizing agent of inestimable worth, although the experiments 66 EATING TO LIVE LONG proved that the lack of animal fats and their vitamine content could largely be made up by the administration of green vegetables. Dr. McCollum brought one batch of rats to the actual verge of starvation by giving them all they could eat of bolted Treating Rats wheat flour, degerminated corn Like Human 1^,1 1 • 1 1 Beings meal (the kmd we ourselves always get), rice, corn grits, starch, molasses, sugar, pork fat, cabbage, sweet potatoes and salt. There was, however, too little of the leaf of the cabbage to " protect " the animals, as ninety-five per cent of the diet was derived from the endosperm, the inner part, of the cereals, together with pork fat and saccharine substances. This is the type of diet that prevails in the regions where pellagra is widely diffused; a diet very similar in its nature to Starving to ^i^^^ ^ ^^^^^ millions of our Death on ^. Food population try to nourish them- selves, fatuously believing they are being well fed while they are doing so. It is a form of diet on which the average person who rarely eats green vegetables, or who seldom drinks fresh, whole milk, would MINERAL SALTS, VITAMINES 6.7 be thoroughly satisfied to starve to death ; and the only reason he doesn't is that occasionally he gets a remission in the shape of a pint of ice cream, or some other food that supplies for a time his vitamine deficiency. These revolutionary discoveries have opened up an entirely new vista into the etiology, or causes, of disease. For there are doubtless many nutritional dis- .j°'^Lack ''f orders which may fall far short Vitamincs of being pellagra, beri-beri, or scurvy, and yet which may present definite disease pictures, in a nervous or constitutional way, that can be readily attributed to a com- plete or partial deficiency of the " water solu- ble B." Within the past few years we have found that a deficiency of vitamines in certain grains will inevitably produce beri-beri, unless the deficiency is made up by a mixed diet, which will .increase the sources of the " water solu- ble B." This was admirably illustrated in a recent outbreak of beri-beri in Newfoundland. The cause of the trouble was found to be a beautiful white "patent ^°^ ^^^ r, „ -r , r , ■ Fishermen Hour. In the process of beauti- Got Neuritis fying this flour all the germ was 68 EATING TO LIVE LONG milled out of the grain, because this was the part of the grain that caused the dark hue of the loaf, so repugnant to the aesthetic tastes of the Newfoundlanders. Just as soon as these people were put upon a diet of whole wheat bread, and as soon as they went back to the use of butter, instead of oleo, they recovered. It has been shown, by the very reliable phosphoric acid test, that corn meal, owing to the fact that it is almost invariably deger- minated, is very low in its vitamine content, and that the germ itself contains six times more of the vitamine substance than does the prod- uct in daily use on our tables. Corn deteriorates very soon because of the large amount of oil it contains. Hence, " de- germinating " methods are introduced into modern milling. The germ, which is removed with the bran, is sold generally to dairies or to hog-raisers, with whom it has a great reputation as a " milk-maker " and pork producer. Thus the very substance which man needs for his development and growth is discarded, and is fed to the cattle or the hogs. In the very interesting and highly instruc- tive experiments with the pigeons it was MINERAL SALTS, VITAMINES 69 proved that the polyneuritis — jj^,^ jj,g which is the analogue of beri-beri Pigeons in man — could be produced quite "^^°''^^ ^p" uniformly by feeding an exclusive diet of de- germinated corn meal. Yet even though the paralysis was complete, the disease was invariably cured within a few hours by the administration of an alcoholic extract of the corn germ. In many instances the extract had to be given in a tube, and massaged out of the paralyzed crop, yet the curative effect of the extract was startling in its thoroughness and rapidity. This, of course, was only a duplication of the work done with polished rice and " rice polish"; but it shows clearly the universality of the law. One of the most vital and revolutionary things in this study of vitamine deficiency is the part played by baking soda and other strong alkalies in the Z^^?° *^^^ 1 r 1 Baking Soda cookmg 01 cereal lood. It has already been proved in the Philippines that cooking soda increased the deficiency of polished rice. In a series of recent experi- ments, however, on fowls and pigeons, it was demonstrated that corn meal cooked with 70 EATING TO LIVE LONG baking soda produced polyneuritis much sooner and much more certainly than when plain corn meal mush was administered to the martyr birds. Baking soda, as everyone knows, is decom- posed into sodium carbonate, a very harmful substance, when it's in food, and into carbon- dioxide, a waste product of which we already have too much in the system. It is the carbon-dioxide that causes the bis- cuits to " rise." Sometimes an attempt is made to neutralize the deleterious effect of the soda upon the organism by adding a certain quantity of sour milk, to overcome the injuri- ousness of the alkali; but there is only an em- pirical guess as to whether or not there is enough. Until we know just how much alkali is suf- ficient to produce serious changes in the efifi- Better Go ciency of the " fat soluble A " Back to the vitamine, it might be very sensi- oid-Fashioned ble for US to go back to the old- gain fashioned method of " rising bread " with yeast, and leave the use of the bicarbonate of soda to those who are not so particular about their health and as to what eventually becomes of them. In fact, we could go back with profit to the MINERAL SALTS, VITAMINES 71 old hoe-cake and corn-pone which our ances- tors baked in the ashes, and upon which they thrived mightily. If we could add to this a kitchen milling- apparatus, grind our own corn and wheat, and use the entire ground product — instead of feeding the essential nutritive salts to the cat- tle — it is quite possible that the practice of neurology might become increasingly less prof- itable, and the health of our populace increas- ingly less interesting to undertakers. All of which leads to the conviction that the ignorance of the average man or woman on the subject of food is almost ^^, „ . ^ ■" It s Hard to unbelievable. Were it not so they Teach an Old would not continue to throw to the ^°s New Tricks pigs the valuable mineral salts in the bran and husks of the grain, and then eat the denatured endosperm themselves. They would not consume billions of pale bis- cuits and thousands of bales of food-free hay. They would not vehemently demand their de- mineralized white sugar, instead of the natural brown sugar that contains vital mineral salts. They would not consistently refuse to eat de- hydrated vegetables — with all the cell sub- stances and mineral salts of the vegetables pre- served indefinitely in a dried state — which. 72 EATING TO LIVE LONG They Would when properly prepared, are al- Have Fresh most as appetizing as are the fresh ?rvf^^ vegetables.

It could be done, merely by the diffusion of correct information, and the universal adop- tion of rational principles. Sometime, prob- ably within the lifetime of men and women still living, all this will be done. Until then, we shall have to keep hammering away in the sturdy hope that sooner or later these things, that should be so obvious, will be universally recognized and uniformly followed. CHAPTER VI FOOD FADS AND FOOLISHNESS There are probably more crazy ideas o: the subject of diet than on any other subjec connected with health. All sorts of fads foibles, and fancies have been perpetrate^ upon the gullible public, who by the score of thousands have been led to seek the elusiv Fountain of Youth through the mediums o starvation, raw food, hay, vegetarianism fruit, nuts, and all other forms of man monkey and squirrel fodder. For some inscrutable reason many of thesi devotees survive, a little anemic and the wors^ for wear possibly, but still able to get about Perhaps the most radical of all diet crank is the individual who for days, or even weeks absolutely dispenses with food. If there is anything the matter with p^aj^^®*'"^ him physically (he is chronically under suspicion mentally) he " starves i out"; not by cutting out the particular item of food that may be responsible for his condi tion, and then building up his system with th( 73 74 EATING TO LIVE LONG proper food, but by eliminating everything except water, and possibly cigarettes. That fasting for a limited time is a splendid thing for one who for years has habitually abused himself by overfeeding, is not to be denied. The system gets a chance to utilize the excess pabulum stored up in the tissues, while at the same time it is given an oppor- tunity to get rid of the accumulated waste. But for the weak, anemic woman, or the pale-faced pie eater, suffering from jaundice, intestinal atony, or malnutrition, to attempt to cure these disorders by abstinence is as ridicu- lous as would be the attempt to cure an auto- mobile of an accumulation of carbon, or a " knock " in the cylinder, by trying to run the machine with water instead of gasoline. It is true that the human machine is fear- fully and wonderfully made, and that it can, under certain conditions, stand a tremendous amount of abuse; but this doesn't prove that the abuse is beneficial. Because Signor Sacco could and did starve himself for forty-six days and four hours, and because the French murderer, Granie, existed without food for sixty-three days before he finally succeeded, in cheating the guillotine, doesn't prove that the process is beneficial. FOOD FADS AND FOOLISHNESS 75 Any good that can possibly come to any invalid from abstaining entirely from food can be multiplied ten-fold by so regulating the diet that the proper food elements in the proper amounts can be utilized to correct the invalidism. It is admitted that the first step in diges- tion is thorough mastication of the food. But this does not necessarily mean that we must adopt the Fletch- The Delusions erian style of "fluidizing" the pietcheriie bolus of nutriment into a pap, until it slips down almost without conscious effort. For good honest chewing, chewing that re- duces the material to such shape that the saliva and the gastric juices can act upon it, is sufficient. There is a happy medium between the jaw- wearing and utterly useless practice of chew- ing food, and " tasting and tasting " it — especially meat or albuminous food, which is not acted upon at all by the salivary secretion — and the quick-lunch style of bolting, which depends upon breaking off a piece that can be swallowed without choking and then washing it down with a swallow of fluid. Remember also that we have more than 76 EATING TO LIVE LONG thirty feet of intestines, the function of which Give the ^^ *° digest and appropriate Alimentary through the lacteal s — the small Tract Some- ducts that convey the digested mg o o jjiaterial into the circulation — converted food products, and then get rid of the unused portions. These intestines require bulk to function- ate upon, just as the kidneys require water. On a concentrated diet, or on one so Fletcher- ized as to leave but a minimum amount of work for the intestines, the alimentary tract " goes stale." A certain amount of work is needed by any organ in order to keep the organ active. If there is no bulk to combine with the end- products of metabolism thrown into the intes- tine the bowels become inert and sluggish. This permits the reabsorption of these poisons into the circulation and starts the vicious cycle of poison-producing that results in the development of more and ever more poison. " Everything in moderation " is quite as good a rule in chewing as in anything else that has to do with physiological func- tioning. The subject of drinking with meals is one which has aroused considerable contention in FOOD FADS AND FOOLISHNESS 77 recent years. Lately the convic- tion is srainins: ground that drink- Should We £ 1 v^ 1 • r J Drink When nig treely with meals is of de- -^^ ^at? cided benefit to digestion. To this contention I must take exception. For I am firmly convinced that the less fluid we take with our meals the less digestive trouble we are likely to develop. This in spite of the recent experiments which have been interpreted to " prove " the contrary. First, because if the food is taken as dry as possible we must necessarily chew this food more thoroughly in order to swallow it with- out strangling. This excites a larger flow of saliva, and consequently a greater quantity of this alkaline fluid is taken into the stomach with each meal, thereby stimulating an in- creased flow of hydrochloric acid in the stomach. With this method of eating, however, the food in the stomach is necessarily in too solid a state for the most perfect gastric digestion. To obviate this, fluids should be taken be- fore or after the meal. This causes the par- ticles of food to be widely sep- arated, and thus to present the or After Meals largest possible surface to be at- —But Not tacked by the gastric digestive ^'^^^ ^*^'^ 78 EATING TO LIVE LONG fluids, without, at the same time, reducing the total of its alkalinity. The best fluid to be taken after the meal is coffee, made rather weak and drunk without Bia k C ff sugar or cream, both of which an Excellent tend to excite fermentation and Aid to ultimate decomposition of the food in the intestines. The active principle of the coffee, caffeine, is a safe stimulant to use in moderation, as it tends to increase the activity of all the diges- tive processes. Tea, which contains tannin, tends to " tan " the food, especially meat substances, and makes it much more difficult to digest. Many people cannot drink tea, in even the smallest amount, without exciting fermentation, which, of course, means imperfect digestion and utilization of the food. If tea is used at all it should be freshly steeped and rather weak; sugar and cream both increase its liability to cause fermenta- tion. Alcohol taken in conjunction with meals also has, in most individuals, a tendency to retard the secretion of the digestive fluids and to increase fermentative changes in the food. Milk is an ideal food — for infants. Also FOOD FADS AND FOOLISHNESS 79 for adults — for a limited time, and under conditions which demand no great amount of physical exertion. As l^ ^* ^^^L*,? , .^ •' Live on Milk? a Steady diet for a hard-working grown person, however, milk must be consid- ered essentially a one-sided food; for milk lacks iron, phosphorus, and the nucleo-albu- mins — which lack inevitably predisposes to anemia and malnutrition, even in children who are permitted to nurse for too protracted a period. Indeed, this protracted use of milk to the exclusion of all other foods tends finally to make children susceptible to infections, and in later life, even to develop tuberculosis. Another disadvantage of milk is that one would require a stomach like a milk can in order to carry around a sufficient supply of food and fuel adequately to " run " the body machinery ; and then he wouldn't have enough oxygen in his system to properly convert the proteid elements. Enthusiastic adults can get along fairly well on an exclusive milk diet for a limited time, say four to six weeks. When ■'.,., .,1 • The Nutrient persisted m, however, milk is gaits in Milk quite as injurious as is any other Not one-sided food; for when taken Assimilated 80 EATING TO LIVE LONG alone, milk is not completely assimilated, fully 18% of it being lost through faulty assimila- tion. At least eight quarts would have to be taken daily to adequately sustain the body in health. When bread and butter or cheese are added the assimilation is much better, for the diet is no longer one-sided. This is proved by the experiments of Rubner, who found that 8.3% of the nitrogen, 6.4% of the fat, and 41.1% of the nutrient salts contained in the milk re- mained unassimilated ; while when cheese was taken with the milk only 3.8% of nitrogen, 7.1% of fat, and 37.5% of the salts were lost. From which it will appear that while milk fills a most important plate in the dietary, it must be taken as a food, not as a fad. I never knew but one Simon-pure, dyed-in- the-wool vegetarian. He never even slaugh- tered a chick in its shell by eating Can We Live jje ate no butter. He Healthily on , f& .„ . , ,. Vegetables? drank no milk. And he was the most cantankerous, trigger-tem- pered cuss it has ever been my ill-fortune to meet. He was a misery to himself and to everyone who ever had anything to do with him, all due to nothing more or less than to FOOD FADS AND FOOLISHNESS Si his dangerous and very unhealthful mode of nourishment. This man was a printer who used to get out a medical journal of which I was editor. Finally, after he had printed a couple of do?en of my Post Graduate Medical School lectures, we noticed a remarkable change in his dis- position and in his appearance. He became really sociable, and almost human. His anemic, cadaverous look was replaced by a rugged wholesomeness. None of us could understand what had hap- pened to the old fellow, until one day one of my students happened into a res- taurant near the school where sat ^^^sj"^ ^'^^^ T/r T-. • • • • *"' Steak Mr. Prmter vis-a-vis with a big, thick, juicy steak. The problem was solved. Our touchy tor- ment was feeding himself real food. He had reformed, and was treating his starved nerve- cells and his anemic blood to regular nutri- ment. The result was so very satisfactory to him, and to his long harassed family, that he never afterwards relapsed. The human system can tolerate a lot of abuse; but this does not prove that abuse is commendable. Forcing one's self to live for a protracted period upon an exclusive vege- 82 EATING TO LIVE LONG table diet is an abuse that falls only a few degrees short of suicide — or slow murder. It is admitted that it can be done, and has been done ; but rarely with profit to one's state of health; for it inevitably produces anemia and under-nutrition, as well as being a fre- quent cause of tuberculosis. Both the vegetable and the animal foods, of course, contain all the elements essential for maintaining life. They both con- ^Z'*^',^^^*^ tain mineral salts, saccharine of Food a ' Perfect One compounds, fats, proteids, and the phosphorus-bearing substance known as nucleo-albumin. Neither one, however, contains these five groups of compounds in just the proper pro- portion for the highest type of nutritive activity. Milk, perhaps, comes nearest to the perfect requirements. But milk is deficient in nucleo- albumin, and it also contains an excess of the saccharine and fat constituents as compared with its proteid elements. In the vegetable class there is an excess of starch and sugar, as well as cellulose — or hay Vegetables — and a decided deficiency in fat. Sugar and ^^* ^^^^ ^^^^^ o^ ^00^ may con- Hay tain a liberal percentage of pro- FOOD FADS AND FOOLISHNESS 83 tein, and in many instances a high percentage of nucleo-albumin. This is especially true of green vegetables and legumes, such as peas and beans. In some of the vegetable foods, such as rice, the proteid constituent is so large, in relation to the starch, that by adding a certain amount of oil, as the Chinaman does, very good results in maintaining health and developing a robust constitution can be secured. But to secure them one must be born a Chinaman — with an ancestry whose alimen- tary apparatus has been trained for hundreds of years in the task of extracting nutriment from rice. For the real test of a food is not its chemical formula, or its so-called calorie value, but its digestibility, its adaptability to the body re- quirements. Of recent years olives have been highly ex- tolled as a food fulfilling all the requirements of meat in the dietary. The truth of the matter is that olives are ,, *f,**^ ^ Meat largely ornamental and condi- mental. Their food value consists chiefly of their oil content, which furnishes heat and energy, together with their minerals — not- ably iron, potash and lime — which increase 84 EATING TO LIVE LONG theii- wholesomeness. But to compare them to protein foods — like lean meat, which builds tissue and nourishes the body — is perfectly absurd, no matter how wholesome they may be in a general sense. One ounce of olives contains about the same amount of fat as does meat (7.8 grams) ; but the meat, in the form of beef, would contain also 6.7 grams of protein, whereas olives con- tain only 0.3 per cent — or about one twenty- second of the constructive food value of meat. As to digestibility, it has been proved be- yond a question of doubt that the animal foods, taken as a class, are much Either Animal ., ,. , , , , or Vegetable ^ore easily digested, absorbed. Diet Will and assimilated than the vege- Sw"^- table foods. This is easily explained by the fact that the molecular structure as found in the animal kingdom is much more simple than that found in the vegetable class. For it is monomeric in construction — that is, its com- ponent atoms are similar; while the vegetable class, on the other hand, is multiple, or polymeric in construction, and has to be changed into an isomeric form before it can be acted upon. This explains the great ease FOOD PADS AND FOOLISHNESS 85 with which animal food can be digested, and is a point that but few vegetarians ever take into consideration, if, indeed, they ever take any of the scientific details of food values into consideration. On the other hand, this ease of digestibility renders the animal class much more likely to sub-oxidation than the vegetable class, unless the quantity taken ^o^re^Meaf^* is continually kept well within the Than You Can limit of the oxygenating capacity Fum'sh r ,, , Oxygen to of the system. Convert When this is done, the digestive powers are conserved, the highest possible grade of nutrition established, and all danger of sub-oxidation avoided. And when under a vegetarian diet, various forms of sub-oxidation disorders are found, as well as nervous defects, from chronic nerve starvation, these rapidly clear up under an animal diet. Vegetable foods by reason of their indiges- tibility are much more prone to excite putre- factive fermentation in the intes- tinal canal; manifesting them- y/^**^J'.l*^ . , f' More Likely selves m wmd-storms of a more to Ferment or less emotional nature, and in the undue irritation they may cause the 86 EATING TO LIVE LONG mucous membrane in their passage through the ahmentary tract. Vegetable foods, on account of their com- plex construction, are much more difificult to digest, to absorb and to assimilate ; hence they are not so economical. Yet there is not so much danger of exceeding the oxygenating capacity of the system when on a vegetable diet, because such a large proportion passes through the alimentary tract undigested and unabsorbed. This is the explanation for the good results that sometimes follow the change from a liberal animal to a liberal vegetable diet. The oxygenating capacity of the system is not ex- ceeded, and Nature does what could have been accomplished in a much saner manner, merely by regulating the quantity of the food taken. If we had four stomachs, and nothing to do, we might get along on vegetable food almost w Ca 't ^^ ^^^^ ^^ ^ cow; but lacking a Afford to hundred feet or more of intes- Emuiate the tines, a large cecal pouch, a cud- chewing technic, and a few spe- cial ferments for the digestion of cellulose, we fare badly on a strictly vegetable diet. Remember that even bread requires five times as much pepsin as meat, and that the FOOD FADS AND FOOLISHNESS 87 chief repair of body structure comes from the albumin, so difficult to extract from vegetable foods. The indigestibility of vegetable foods, and the large amount of fecal matter they produce, while they may have a tendency to loosen the bowels, are always J^*„^*^'fr ' / mg Vegetable a source of danger. First, be- cause they carry quantities of incompletely digested food out of the system, thereby rob- bing the individual of a large part of his nutri- ment; and second, because of their likelihood to produce irritation, resulting in intestinal catarrh. If this occurs, the excessive production of mucus forms a favorable nidus for the growth of abnormal microorganisms, danger- ous to health, because of their activities in exciting putrefactive fermentation. The excessive amount of sugar in the vege- tarian diet is prone to undergo fermentative changes, causing more irritation, and still fur- ther favoring the development of putrefactive fermentation. Furthermore, all the cane sugar of vege- tables has to be converted into glucose before it can be absorbed, which conversion is an ex- cessive tax upon the digestive energy. 88 EATING TO LIVE LONG Of course, provided one does not die from the experiment in the interim, the system can ultimately become accustomed to utilize vege- table foods ; but those who care anything about their health will secure the largest amount of it by using both animal and vegetable foods in combination ; in other words, by a well-regu- lated mixed diet, but one in which the animal food always predominates. While it must be admitted that certain swashbuckling death defiers have subsisted for a time in apparent good Peanuts, health on a diet of peanuts, or Squirrel Food . r ji r j and Hay pecans, or the loodless foods so graphically represented by altru- istic merchants as manna in the wilderness for hungry humans, it must be insisted that these feats in dietetic legerdemain cannot be taken seriously. The foods are so " one-sided," so far from being a balanced ration, so absolutely unfitted for protracted human use, that they do not even warrant serious consideration. Squirrels and other rodents, well provided with the ferment, cytase, which enables them to digest the cellulose in such foods, can thrive upon them; but the average human, lacking cytase or a gizzard, or a half dozen stomachs, FOOD FADS AND FOOLISHNESS 89 cannot. And the shorter a time he tries, the longer a time he'll live. At some of the famous " grape cure " re- sorts in Germany and Austria great quantities of grapes are taken daily for the relief of various organic disor- ^ ^^^^^ * ders, chiefly induced by drinking beer and eating six or eight meals a day. It goes without saying that the grand house- cleaning these patients get from the action of the fermenting grapes and their seeds and skins is undeniably of immense benefit. But any other laxative, less likely to irritate the intestinal canal, would probably do quite as much good, and not nearly so much harm; for the excess of acids in the grapes tends to reduce blood alkalinity, and to throw the chemical balance of the secretions out of their normal proportions. This excess of acid is tolerable for a little while, but may excite grave disorders if persisted in. Of course fruit contains mineral salts and alkaline bases that give it a unique food value — when properly used ; but it is so seldom properly used that it has become one of the chiefest sources of all danger. When Metchnikoff expounded his theories regarding the cause of senility, asserting that 90 E ATING TO LIVE LONG Does Sour the daily use of sour milk would Milk Prolong conduce to longevity, he naturally ^'^^^ had an interested audience; for, " everything a man hath will he give for his Hfe." While, unquestionably, putrefactive fermen- tation in the large intestine is a cause of many degenerative conditions — conditions which undoubtedly contribute to senility — and while the use of the Bulgarian bacillus or the lactic acid ferments will lessen the number of bac- terial flora in the upper intestine, it is doubtful whether nearly so much importance can be at- tached to the bacteriacidal action of these bac- teria as has been claimed for them. They simply haven't lived up to their reputation. Milk is of benefit in certain conditions. Sour milk is even more of a benefit, for it has already undergone lactification, one important process of digestion. The ease with which soured milk is assimilated, and the small amount of residue it leaves, makes it a valu- able food form. But as a panacea for old age, and as a cure for most of the diseases which mankind ac- quires or inherits, it leaves much to be desired, because the lactic, acid bacillus does not become the dominant organism in the intestine, even FOOD FADS AND FOOLISHNESS 91 though it may be present in mod- . o i hm erate numbers ; and when the Food— But No lacto-bacilHne, or the artificially Panacea for soured milk, is stopped, the B. ^* Bulgaricus dies in a few days, showing that he hasn't established any permanent domi- ciliary interest in the intestinal tract. Matzoon, Kefr, Kumyss, and artificially soured milks, are splendid foods. But, cost and food value considered, it is doubtful if they are any better Home-Brewed than home-brewed sour milk, or Sour Milk J. i_ ,. Ml Also a Good even ordinary buttermilk. Ljfg_ Any bacteriacidal efifect that Lengthener can be secured with any of these prepared milks can be secured, with almost equal facility, with the home-prepared varie- ties, and at a very greatly reduced cost. Of course, these are only a few of the most common delusions of diet. To treat them all would require an encyclopaedia and might bring on an acute attack of gastrophobia. CHAPTER VII THE FALLACY OF THE CALORIE A calorie is the length, breadth and thick- ness. — as well as the fourth dimension — and the shortest distance between two points, of the limit of credulity. For no more colossal humbug has ever been perpetrated by the medical profession than the humbug of at- tempting to measure food requirements as one would measure fuel needs. Yet scientific men, who should know better, are lending their sanction to the belief that nutritional requirements can be translated into terms of heat units; medical colleges are teaching the " science " of calorie measure- ment; hospitals and sanitaria formulate diet lists for helpless invalids and convalescents, based upon the patient's supposed calorie necessities; while nurses are taught to regard the calorie almost as a fetich — to be wor- shipped with bated breath and whispering humbleness. Even restaurants have adopted the absurd- 92 FALLACY OF THE CALORIE 93 ity, and are printing before each item on their bills of fare the calorie value of «nts ArTcet- *^^* particular item — probably ting Scientific in a heroic attempt to divert the eater's mind from the inflated price on the other end of the printed line. The restaurants justify their patriotic and self-sacrificing course by stating that the calorie figures are computed by experts in nutrition, and that the study of the energy value of the food, multiplied by the price list of the various items, " will permit customers to conserve food by ordering scientifically." Now, when medical colleges, hospitals, die- titians, nurses and restaurant keepers unite to propagate a delusion, what earthly hope has the poor layman of escaping the infection? And so the belief is widespread, and gener- ally gaining ground, that one's food require- ments can be accurately measured in calories — notwithstanding the fact that a person can be fed upon the most formidable calories on the bill of fare, and yet promptly and effect- ively starve to death. First, just what is a calorie? The calorie is a unit for measuring either heat or energy, which, of course, are trans- 94 EATING TO LIVE LONG mutable properties of matter. It represents the amount of heat required to raise the temperature of a kilo- ^l^^^ * gram of water (35 ounces) one Unit degree Centigrade, To raise the temperature of the kilogram of water ten degrees would require ten calories, and so on. In terms of energy this means that- one calorie of heat generated in a steam engine will produce enough energy to lift a load of three pounds one foot in the air. Therefore, the number of calories necessary to do this amount of work is the mechanical equivalent of three foot-pounds. To determine the value of any food in terms of its energy and heat producing capacity an instrument called the " calorim- eter " is employed. This instru- ^°7' *li' , '^ •' Thing Works ment is constructed on the plan of a vacuum bottle or a fireless cooker. It is equipped with a surrounding of ice or ice water so that the interior of the apparatus remains unaffected by the exterior heat. In the centre of this contrivance is the " bomb." This contains a measured amount of the food or material to be tested for calorie units. This material is surrounded by a defi- FALLACY OF THE* CALORIE 95 nite quantity of water, the temperature of which in this compartment would naturally be raised by the burning of the food or similar substances in the bomb. • This material is now ignited and consumed by electricity. The raising of the tempera- ture of the surrounding water is noted by means of a very sensitive thermometer ex- tending into the water. In this way it can accurately be computed that meat, bread, but- ter, cheese, candy, or 'any other combustible substance, has a heat-producing value of just so many calories. So far, so good. But what does it prove? It proves merely that food that can send the mercury to the boiling point may yet be totally devoid of all that is needed in Calorie Values ^^^^^. ^^ maintain the body in a a Myth ■' State of health. For food that is oxidized or consumed in the human body is burned by chemical action — which is an en- tirely different thing from combustion, the combustion that takes place in a furnace, or in a calorimeter bomb. On the basis of these measurements fat, for instance, yields approximately twice as much heat as do the sugars or starches, or even the proteins. In fact, weight for weight, fats 96 EATING TO LIVE LONG have a much higher calorie value than any other type of food. Yet who would be obtuse enough to believe that a fine, calorie-filled diet of fat would be best adapted to supply all the requirements of growth and nutrition? Calorie scientists lose sight of the fact that a considerable part, of the heat which resvilts from the oxidation of food in the calories Can't body, goes to maintain normal B"Ud Tissue, ^ ^. A ^.u *. u \u Make Blood. temperature, and that where the ^^ strengthen oxidation processes are impaired Bone by disease or faulty nutrition, no amount of calorie value can be depended upon for this purpose. Nor can calories, no matter how numerous, put iron into an anemic blood corpuscle, or in- crease the amount of manganese in the color- ing matter of the blood. Foods which have the very highest percent- age of calories are absolutely worthless for building fluorides around the tooth structure, or for feeding calcium and phosphorus intc the bones. Calories have nothing to do with main- taining the normal alkalinity of the blood, and preventing acidosis; or supplying the bod) with magnesia, sodium, sulphur, potassium, oi other mineral salts and colloids, which are in- FALLACY OF THE CALORIE 97 dispensable in the control of the various in- tricate metabolic processes of the body. In short; the scientists and dietitians who have become devotees in the worship of the Great God Calorie have entirely lost sight of the fact that the food requirements of the body, as expressed in the actual chemical needs of the organism, and the fuel, or energy re- quirements, as expressed in terms of calories, have no more to do with one another than have ships, soup-tureens and Mad Hatters. Notwithstanding all the weight of scien- tific authority, of Government Reports, of hospital, sanitarium and dietetic ^tieJTf" formulas, I contend that the Diet Tables calorie is valueless, misleading, and absolutely to be condemned. It ignores the function of nutrition, and the thousa.nd and one equations that enter into this function. It takes not the slightest thought of the colloids, salts, ferments, en- zymes and vitamines — which substances, in many diseased conditions, may be the most essential of all food elements favoring the restoration of health. Calorie enthusiasts ignore the fact that food- stuffs can be refined, as indeed they are being refined every day, until not a trace of the col- 98 EATING TO LIVE LONG loids, salts, ferments, enzymes and vitamines remains in the food ; and yet the high-sounding calorie value of the food remains unchanged. The " science " of calorie values fails to recognize the growth-promoting value in foods which, though valueless from the standpoint of the calorie tables, nevertheless are abso- lutely indispensable in maintaining normal blood fluidity; in regulating the secreting activity of the ductless glands; in preserving to the organism its marvelous ability to func- tion. Alfred McCann, in his book " Starving America," and in his popular articles on dietetic chemistry, has persistently maintained this position. While Henry T. Brooks, M. D., Professor of Pathology in the Post Graduate Medical School and Hospital, states emphatic- ally that " For some time past I have felt that the feeding of humans on the calorie basis is defective — in fact, a ' delusion and a snare.' It has been conclusively revealed as an error, and the sooner the medical profession recog- nizes the falsity of the theory, the more profit- able will it be for those who depend upon physicians for direction and advice." In a recent article in the Journal of the American Medical Association, Dr. Henry D. FALLACY OF THE CALORIE 99 Chapin expresses similar views, and makes a strong plea for a reform of this folly. Dr. Thomas B. Osborne and Dr. L. B. Mendell, of Yale, in a most interesting series , of experiments, demonstrated Starving to ^^^^ animals fed with mixtures Death on Rich Food 01 refined protein, refined sugar, fat and starch — the richest pos- sible foods, so far as calorie value is con- cerned — rapidly sickened and declined under this diet. This, even when the food was mixed with inorganic matter. When, however, milk whey, which has abso- lutely no caloric value worth measuring, was added to the feeding, the tissue starvation in the animals was checked. Whey contains none of the fats or proteid of the milk. It is merely the clear watery fluid in which the milk corpuscles float, as do the blood corpuscles in the blood serum. But it contains iron, calcium, potassium, phos- phorus, and other minerals, and probably some of the growth-promoting vitamines present in the milk; and, in spite of its insignificant calorie value, it proved to be a regular elixir vitae to animals condemned to die of starva- tion on high calorie foods. Foods such as salt pork (which contains 100 EATING TO LIVE LONG 3555 calories), oleomargarine (3410 calories), refined sugar (1750 calories), white bread (1200 calories), and corn meal (1630 calo- ries), when fed to animals, to the exclusion of other foods, inevitably produce degenerative diseases and ultimately the death of the animal. Corn starch, corn grits and corn syrup, cream of wheat, polished rice, macaroni, tapi- oca, white flour, and puflfed rice, are peculiarly fatal, owing to their deficiency of mineral salts. Yet foods which are insignificant in the calorie scale, as, for instance, buttermilk (160 calories), skimmed milk (165 calories), pota- toes (160 calories), string beans (170 calo- ries), cabbage (115 calories), lettuce (65 calo- ries), celery (65 calories), spinach (95 calo- ries), are veritable life-savers. When added to the diet of animals being systematically starved on high calorie foods, they speedily arrest tissue decline; but the animals do not fully recover, nor do they re- gain their weight and their procreative power until they are once more fed entire grain sub- stances, containing the mineral salts which they vitally need, and the vitamine-containing foods — the " fat soluble A," and the " water FALLACY OF THE CALORIE 101 soluble B," discovered by Dr. McCollum, as described in Chapter V. When these substances, in the form of let- tuce, spinach, cabbage leaves, butter and but- ter fat, together with the germ of corn, rye, or wheat, and the bran of cereals, is added to the diet, the animals recover a perfect state of nutrition. Organic beings live on food. The calorie is no part of food — either protein, starch, or ,„ „ , , . sugar. It contributes nothing to We Don't Live *= . . =" on the Thing the nutrition of organic bemgs. That Measures f ^g calorie has no connection with lecithin, phosphorus, mineral salts, or the vitamines — biochemic substances that are vitally necessary to health and growth and the maintenance of immunity from dis- ease. The calorie is merely a tape-measure, in- tended to determine accurately the needs of vital processes. But vital processes are un- measurable and unweighable by any system that ignores the activities of life itself — of nutrition, of metabolism, or assimilation, of physiological or pathological functions. The calorie deals with dead things — car- bon, nitrogen, and the elements which un- dergo changes in their physical form. 102 EATING TO LIVE LONG Food is reconstructive and vitalizing ma- terial, profoundly complex in itself, and in- finitely more complex in its processes and in its functions. Food is intended to per- petuate the organic residence of a marvelous activating entity — an entity that lives for a time in this residence. So merely to measure the oxidation re- quirements of this complex organism isn't enough; if it were, the calorie would de- serve the devotion of even its most enthusi- astic worshippers. As it is, however, the calorie theory is really a tale told by a grandam; a thing of sound and fury, signifying nothing — ex- cept that credulity is the most highly devel- oped attribute of man. CHAPTER VIII FOODS THAT POISON Most proverbs are platitudinous drivel, foisted upon the gullible by reformed sin- ners too old or too anemic to longer enjoy doing the things from which they would have everyone else abstain. There are a few exceptions to this gen- eral rule, however. One relates to the indi- vidual capacity for " handling food." It says: "One man's meat is another man's poison." On the face of it this looks ab- surd, particularly as there is not the slight- est particle of scientific evidence to explain why this should be so. But " experiencia docit," as we used to say in our old school days. Experience teaches that the idiosyncrasies of certain people against certain kinds of food are not to be explained on physiological grounds. Neither are they due to suggestion or to imagination. For the first principle of suggestion de- 103 104 EATING TO LIVE LONG mands that the mind consciously cooperate to influence the functions of the body. How can the mind act, if it doesn't know that there is anything to act about? It is a matter of common knowledge that hundreds of people are made deathly sick by eating a piece of cake, or some ettmg other article of food that may Poisoned on _ _ ■' Milk and Eggs Contain what nine out of ten of us would consider harmless neces- sary eggs or milk. Without the slightest knowledge on their part that they are poison- ing themselves with these delectable food- stuffs, they are made deathly sick — with vomiting, retching, colic, diarrhea, and a gen- erous sprinkling of other symptoms of acute arsenical poisoning. Of course we understand that the yolk of the tgg is an exceedingly complex body, with a capacity for breaking up into a number of active poisons when undergoing the process of decay. But why should a perfectly fresh ^^g act with some people as though it were a very bad ^g%l Why should pure milk, the most vital and indispensable of all food forms, produce in certain individuals the symptoms of ptomaine poisoning? FOODS THAT POISON 105 This idiosyncrasy is not confined entirely to adults, as might naturally be expected. There are instances in which even infants, when fed cow's milk, develop these same symptoms, and finally have to depend entirely upon albitmin water or a wet-nurse for their chance of life. Cheese is another food that acts as an irri- tant poison to many individuals, and that even the strongest and hardiest, unless toughened and inured to its rav- 3^'^° Weak"^* ages, can eat only in limited Bodies amounts. This is unfortunate, in one way. For, theo- retically, cheese is an excellent article of diet, giving almost twice as much proteid as beef, for the same price, and four times the amount found in eggs. Cheese has a pleasing taste, and in small amounts is relished and well di- gested by most people. Yet the ferments and the extracts developed in even the mildest of cheeses during their process of ripening have an extremely irritat- ing effect when taken into the stomach of the majority of people, in anything except mini- mum quantities. This is especially true of the strong Stilton, the sturdy Roquefort, the valiant Brie, the militant Camembert, and the potent Limburger. 106 EATING TO LIVE LONG The constipating effect of cheese is quite universal, although I have known patients in whom cheese produced exactly the opposite results, and who derived great satisfaction from its use as a laxative. Weight for weight the bean — with its brother-in-law, the pea, and its sister, the len- til — is probably the cheapest w L 1. • and most nutritious food on Misbehavior of Beans earth. As a proteid producer it is almost in a class by itself, price for price, being only about one-eighth as expensive as a regular egg. Based upon its nitrogenous content, and its really commendable nutrient qualities, the bean may well occupy the commanding position it maintains as the vegetarian's hope and joy. But, as with every other fad-food, which can only be eaten about every so often, and in extremely moderate quantities, by the average man, beans are objectionable. They disap- point the enthusiasts' expectatioiis. For careful experiments show that, not- withstanding their high nutritive value, peas, beans, lentils, and other legumes, if taken in excess of one-fifth the protein requirements of the system, produce distressing flatulence, a loss of appetite, bowel irritation, and if per- FOODS THAT POISON 107 sisted in, a failure of nutrition. Stock breed- ers have demonstrated the same thing in the feeding of cattle. The reason is that inextricably bound up in the bean, is an aromatic oil and a bitter alka- loid, both poisonous to. the sensitive stomach in small amounts, and to- most stomachs in larger quantities. This explains why even the Bostonian indul- ges in beans only Saturday and Sunday, and eats codfish cakes and food the remainder of the week ; and why boarding-house keepers, and lumber camps, and the army mess can't have beans any of tener than they do — without ex- citing a riot. In fact, it explains why no one, except a Mexican, a Trappist monk, or some individuals immune to any ordinary poison, can live on them as a staple article of diet. In consideration of their high dietetic value, and the comparatively limited use the human race, as a whole, can make of legumes, there is a vast fortune awaiting the man who can discover a means for extracting the teeth of the bean and making it behave itself. Nuts constitute another prize food which is, according to the analysis and the statements of those who have more enthusi- why Nuts Are asm than information, specifical- Not Food 108 EATING TO LIVE LONG ly adapted to replace meat and animal proteid. It is contended that to solve the present prob- lems as to our chief source of nitrogen supply, and at the same time prevent further crimes against the cow and her dumb associates, all that is necessary is to. plant great groves of walnuts, brazil nuts, hickory nuts, and pecans ; and go in, at the same time, for peanut raising on a lavish scale. For analysis shows that nuts contain proteid and fats in a readily digestible form. But this does not do human beings has not a squirrel-like capacity for resisting the irritating action of the poisonous principle found in the kernels and skins of nuts can live on them. Theoretically nuts are fine. Practically they are impossible. Except in very minimum quantities, taken at rare intervals, they are highly inadmissible as articles of food, as any excessive amount is likely to produce indiges- tion, diarrhea, and perhaps even appendicitis. Those who extol so vivaciously the virtues of the banana as a food for humans are The Baneful- ^^^^% mistaken; for while the ness of banana is rich in starch and Bananas sugar, and while it has undoubted FOODS THAT POISON 109 food value, it can never become a staple article of diet for the average individual. If taken raw, in a slightly under-ripe state, as mostly it is the custom to eat bananas, the uncooked starch is very difficult to digest. If over-ripe the fermentative processes already set up are likely to continue in the digestive tract, in which there is already an excessive amount of fermentation. ^ Baking the banana kills fermentation, helps to break up the starch granules, and increases the digestibility of the fruit; but not many people care for the banana in the pasty condi- tion which baking usually produces. There are any number of individuals to whgm strawberries, no matter how ripe they may be, or how carefully washed, are a source of rank poison, pro- The Mark ducing rashes and irritation of strawberry the skin, swelling of the lips and tongue, or even pain in the joints. This phenomenon is observed even when the berry is disguised in confectionery, pas- tries or jams; so that the objectionable fea- tures of the berries are not due, as many claim, to molds, bacteria, or the presence of insect parasites. 110 EATING TO LIVE LONG With some this idiosyncrasy extends even to melons, prunes, grapefruit and oranges, apricots, peaches and plums ; and many are im- mediate victims of a gas attack following the eating of even the smallest particle of raw apple. There is hardly a person who is not him-, self affected, or who does not know of some- one who is affected, by various Picking the of the vegetables — particularly Veyelabie onions, beets, radishes, aspara- gus, spinach, corn, cucumbers, sage, parsley, string beans, turnips, cauli- flower or cabbage. Some of these vegetables, of course, are objectionable by reason of the tough, indiges- tible cellulose of which they are largely com- posed. Others, as for instance, the onion, are taboo by reason of the volatile oils they con- tain. Indeed, it is not at all unusual to see cases of gastritis, or even acute colitis, excited by eating two or three boiled onions, or by in- dulging in a chop suey banquet. Upon general principles of common sense and dietary rationality, it is an excellent prac- tice to avoid the use of any food which makes its exit from the body chiefly as wind, and FOODS THAT POISON 111 contributes little or nothing to the nutrition while so doing. Then there are people to whom fish or fish roe, lobsters, clams, oysters, crabs, and cockles, even in their freshest state, are on the index expurgatorius ; for pish koodoo their use is followed almost in- variably by symptoms of ptomaine poisoning, or by a most distressing nettle-rash. One reason, probably, why the mussel, found in such profusion all along our shores, is not more generally employed as an article of food, is because of the frequency with .which it excites digestive disturbances in susceptible individuals. The poisonous element is supposed to reside most profusely in the byssus, the " beard," of the mollusc, but to many individuals any part of the animal, even the essence taken in the form of broth, is equally objectionable. These are facts, discreetly to be reckoned with in the important matter of dealing with the diet. Diet reformers and others, attracted more strongly by theories than by facts, may ignore them, if they choose; but if they do, their crime be on their own heads ; for if there is any virtue at all in common sense, the ra- 112 EATING TO LIVE LONG tionality of abstaining from the hurtful would appear to be an indication of a goodly amount of it. CHAPTER IX HOW UNDER-NUTRITION INVITES DISEASE. There is no one fact in medicine more clearly demonstrated and more definitely proved than that our imnfiunity against dis- ease of every kind depends upon the forma- tion and the composition of the blood, and that chronically under-fed individuals are peculiarly susceptible to contagious diseases. The great epidemics of history, as a rule, have followed almost invariably a period of famine. Or they have gained their foothold after a course of diet in which — as with the severe epidemics of influenza and pneumonia, which swept the world during the latter years of the Great War — the populations were forced to sustain themselves on food abso- lutely lacking in some of the vital elements necessary for proper nutrition. We know, beyond the question of a doubt, that the poor, in whom the matter of adequate nourishment is a serious if not an insurmount- 113 114 EATING TO LIVE LONG able problem, are much more liable to a dis- ease like tuberculosis, for instance, than are those who are able to buy immunity through a more liberal and nutritious diet. Tuberculosis, the most serious of all the wasting diseases, is, in the light of these find- ings, no longer regarded as an Tuberculosis inherited disease; for it is now Not Inherited generally admitted that it must be acquired after birth. The child may be born with a low chemico- nutritive quality or capacity, and its power to resist germ infection will, as a consequence, be very slight. This, however, does not neces- sarily mean that the child will ultimately be- come tuberculous. It simply indicates that such a subject has a strong predisposition to be- come easily infected by the germs of tuber- culosis. The nutritive activity of such a sub- ject is in an abnormal condition, so that a suit- able soil for the growth of the germs is readily produced by errors of diet, or by a diet defi- cient in protein — the true building material, and the only material of which tissue can be reconstructed. Slight causes may then produce a break in the continuity of the integument, or mucous membrane, thus enabling the germs to gain UNDER-NUTRITION Hi access to the system at a time when it lacks the nutritive activity to resist their damaging effects. When this has been accompHshed, the individual may be truly said to have tuber- culosis. But not before. This same thing is true of every other infectious disease, no mat- ter what its nature. As the lowering of the chemico-physiolog- ical forces plays such a large part in inviting disease, and as errors in diet, or deficient diet, is so largely respon- Maintain ^ sible for the deteriorated condi- ^n^e by Food tion of the system, we are justi- fied in assuming that the predisposition toward tuberculosis, or other wasting disease, can be bred and fed into a family. On the other hand, the same predisposition to tuberculosis and other diseases can be bred or fed out of a family. If the parents are of reasonably sound habit, if they are so placed in life that they can live under proper hygienic conditions, and if they confine The Responsi- their diet to food that is plain parJn°s and easily digested, yet highly nutritious in quality, other things being equal, their offspring will be possessed of a higher chemico-nutritive vitality than when these 116 EATING TO LIVE LONG conditions are reversed. The child will have a high resistance, not only against tuber- culosis, but against all forms of infection. Therefore, it devolves upon physicians, as guardians of the public health, to try in every possible way to educate human beings to be more careful in the selection of their life- partners. Theoretically, both parents should be ex- amined by a competent physician before being able to close the final contract. If such rules — which are carefully followed in the mat- ing of pigs and cows — were applied to the mating of human beings, one great factor in the predisposition to disease would be at once removed. When man is more universally mated in accordance with these ideal standards, the problem will be partly solved. Yet it would still be necessary to exercise the greatest care in the selection of a proper diet, and in the establishing of perfect sanitary surroundings. This is especially true as regards the mother during the child-bearing period of her life, if strong and healthy children are to be pro- duced. Yet little thought is given to this im- portant question. Consequently too many chil- dren are brought into the world with en- UNDER-NUTRITION 117 feebled constitutions, when they might, with Httle care on the part of the parents, have been born strong and robust. The practical condition, however, with which physicians have to contend is the management of children or young adults that have been born of un- "^^^ Practical wisely mated parents, or else with Matter children of women, primarily healthy, who have been poorly fed, or over- worked, or compelled to live in unsanitary sur- roundings during the child-bearing period. In either case the offspring is likely to be brought into the world in a low state of chemico-physiologic activity. Yet if we study nature closely, it becomes apparent that the nutritive vitality of the infant before birth is, as a rule, likely to be conserved at the ex- pense of the mother's nutrition. Thus it not infrequently happens, as was •demonstrated in the prize baby contests held in this city a few years ago, that a fairly healthy child is produced by a weak, enfeebled mother. In such instances the mother cer- tainly is not a fit subject to nurse her off- spring. If allowed to do so at all, she should suckle her child for only a brief space of time. During the child-bearing period the mother 118 EATING TO LIVE LONG should be kept upon a well-regulated mixed diet — one in which the animal PleiSrof ^^^"^ proteins predominate, as this class Animal Food of proteid always yields the larg- est nutritive returns with the smallest expenditure of digestive and assim- ilative energy. This provided for, the mother and child, assuming that the hygienic conditions are good, will develop and maintain the highest possible nutritive standards. There will be produced, also, the greatest power on the part of the system to resist infection of all kinds, including the tubercular. The mother will, under such conditions, probably have a good supply of milk, of a rich quality. Under these circumstances, and no other, the mother is fit to nurse her child. The nurs- B t D 't *"^ period, however, should never Nurse the be too long extended. For it is Baby Too now well established that milk °"^ contains too low a percentage of nucleo-albumin to enable it to produce the best quality of blood. Therefore, a protracted nursing period has a tendency to develop an anemic child. This is one of the strongest of all arguments UNDER-NUTRITION 119 against the long-continued use of milk to the exclusion of other food-stuff. When the mother is not physiologically ca- pable of properly nursing her baby, or when the time has arrived when the child should be weaned, cow's milk should be substituted for the mother's milk, rather than some one or other of the innumerable artificial foods — for all of which the claim is made that they are far superior to those that are produced in and by the laboratory of nature. A child that cannot be made to thrive upon a good quality of cow's milk, properly pasteur- ized and diluted, or to which a suitable quan- tity of albumin water or barley water has also been added, stands a very good chance of sometime becoming a subject for tubercular infection. As the child advances in age, the diet must be enlarged by the addition of soups and beef- broths; then by the more solid food-stuffs, such as eggs, meats. Children Also bread and butter, and a moderate p^^^ quantity of vegetable food, judi- ciously selected. It should always be borne in mind, in this connection, that the * animal proteid is the most economical to the system, and that when 120 EATING TO LIVE LONG the quantity is properly adjusted, it will, if combined with the limited use of the vegetable class of food-stuffs, invariably yield the high- est nutritive value attainable. The same rigid rules regulating the diet, both as regards quantity and quality, should be maintained throughout life. Especially should they be maintained during those periods of most rapid growth, when the largest amounts of nourishing substances are required by the system. Irideed, a vegetable diet, or a diet in which the albvimin is reduced to a minimum, may, particularly during the years of puberty, have an absolutely murderous effect. Remember always that food is essential to growth, and that to properly maintain body heat, rebuild the worn-out cells, prevent under- nutrition, and conserve the body from the at- tacks of the myriads of microbes that day and night await only a favorable opportunity to attack the tissues, food is required. When, as has been disclosed by the investi- gations of the American Open Air School Journal and by other authorities, children are under-nourished because of the straitened financial condition of tfieir parents, the prob- lem becomes even more complicated. UNDER-NUTRITION 121 But this is a subject for the sociologist and the economist, rather than the dietitian. The physician can only point out what is required to be done, not the means for doing it. If only it were possible, however, even to set upon the right track those who are finan- cially able to stay on this track, much might be accomplished ; for tuberculosis and wasting diseases, together with the present high pre- disposition to contract infectious diseases, might be largely bred and fed out of the human species. This would be something well worth accom- plishing. CHAPTER X THE CRIMES OF COOKS The traditional idea about what constitutes good cooking is about on a par with the answer of a pupil in the biology class, who said a lobster " was a red animal that walked backwards." The genial professor agreed that this statement was correct — with the trifling exceptions that a lobster was not an animal, but a shell-fish; that it wasn't red until it was boiled; and that it did not walk backwards, but sideways. This measures up pretty well with cooking in general, especially Mother's cooking. We used to like Mother's cooking. With our omnivorous appetites, and our tremendous oxidizing capacity, we might, as children, have liked anybody's cooking. As a matter of fact the mothers of the present generation, and of the generation im- mediately preceding the present Mother Really generation, were really novices in Only an the art of cooking, and also in Amateur 122 THE CRIMES OF COOKS 123 their knowledge as to what constituted food values and a balanced diet. This explains why only three out of eight hundred and forty-six school children, exam- ined in a representative Cleveland school, were free from dental disease of one kind or an- other; and why, of ninety thousand children examined in Chicago, 95% were in need of dental treatment. The reason is obvious. For one thing the average mother insists upon having, and feed- ing to her family, only 1;he whitest of white flour, from which every particle of tooth and bone building mineral has been removed. She feeds her family on batter cakes, grid- dle cakes, pies, and other delectable foods fried and baked in grease, which substance per- meates the starch granules and coats them over with a layer of indigestible fat. She frequently mixes sugar into the mess, and over this she and her family pour an ad- ditional amount of the sap of the sugar cane, which has been boiled down and refined, mak- ing a highly concentrated and dangerous gastric and intestinal irritant. On state occasions she will make up a batch of stuff which is fried in a deep kettle full of 124 EATING TO LIVE LONG boiling hog's grease, thoroughly insuring the indigestibility of the starch granule. When sufficiently cooled these doughnuts will be treated to another dose of powdered sugar, still further to increase their trouble-making proclivities. '^^^ Sinker of These "sinkers," as they are called gtory by the elite, are a favorite diver- sion in the American Home, and at the Ameri- can Quick Lunch Counter. Incidentally, they served valiantly, during the late trouble in Europe, to make our soldiers forget for a time the horrors of war. Notwithstanding their wide popularity, they are among the most pernicious and unwhole- some foods that have ever been inflicted upon a trusting populace. They have caused, and are causing, more digestive disturbances than any other one article of food eaten in America — with the possible exception of the so-called " batter cakes " — which are lumps of raw dough, heated through for a few moments, and browned or burned on the outside. These semi-raw lumps of indigestible starch are in a class by themselves as specimens of what a food should not be. They may be a joy while eating, and for about a half an hour or so afterwards. Nevertheless, it is highly THE CRIMES OF COOKS 125 probable tha,t they, together with a lot of other maltreated food, have, in the past, driven more men to drink than all other forms of trouble combined. ' Then there is the frying-pan, or skillet, elevated to a post of honor in most American homes. This institution is also a Toughened ^^-^^^ trouble-breeder, from the fact that the majority of women fail to use a fire under it sufficiently hot to sear over the meat during the process of fry- ing, and so retain the savory juices. This is partly due to the fact that lard, but- ter and other animal fats are used in cook- ing. These animal fats have a low burning point. Hence, if used at a temperature that would adequately cook the meat, fish, or other food, they have a faculty of proclaiming to the entire neighborhood just what the family is going to have for dinner, to say nothing of the fact that the meat being prepared is toughened and rendered almost indigestible by its protracted seance in the frying-pan. If broiling is not practicable, it is possible, through the use of corn oil, olive oil, or some other vegetable oil — capable of being heated to 600° or more before the burning point is reached — to greatly help in taking the teeth 126 EATING TO LIVE LONG out of the frying pan," and at the same time serve to make the food more palatable and digestible. It would also be infinitdy better if we in America would learn to steam vegetables, in- stead of boiling them in water and then throwing the water y^^"^^^^^ away; for this practice causes the loss of many of the nutrient salts, which are dissolved out of the vegetables in the process of cooking. It would be much better to let the vegetables simmer in a little water, then steam in their own juices, and serve them with all these juices. Or they could be cooked in closed ves- sels, as with the admirable method utilized in the principle of the " fireless cooker," now in general use. Or they could be cooked in closed vessels on the " double-boiler " plan. The aroma is thus retained, the food has a better taste, and the nutrient salts are kept, instead of being poured down the kitchen sink. In this slower form of cooking vegetables, the starch granules are given an opportunity, to burst open naturally by the heat; whereas, if the heat is too great, as in intensive boiling, the starch granules may shrivel up, while the THE CRIMES OF COOKS 127 outer covering of cellulose may remain intact, thereby increasing the indigestibility of the cereal or vegetable. It is just as easy to cook scientifically as it is to spoil food unscientifically ; but in order to do so, the fundamentals of cooking must be comprehended, and judiciously followed. CHAPTER XI THE EVIL. OF FRUIT If there is any one fact of which I am thor- oughly convinced it is that the eating of fruit, especially in conjunction with the meals, as is commonly practiced In this country, is one of the most pernicious and reprehensible of all dietetic follies. First, because the taking of fruit acid with other foods has a tendency to inhibit the nor- mal secretion of hydrochloric acid — indis- pensable to the proper peptonizing of the albuminous foods. Secondly, because when fruit acid is used at the same time that starch and sugar are taken into the stomach, it excites fermentation of the starches and sugars, thereby causing the production of an excessive amount of lactic acid. The result is that the stomach contents, after an interval in which, normally, peptic digestion should be well on to- Too Much wards completion, consists of a A"l i I i!ltii!|||||!i!!il'H'fit!
