  The human body is so wonderfully made that as yet we have only a poor understanding of it, but we are learning a little each decade, and perhaps in time we shall have a fair knowledge both of the body and of the mind. Body and mind can not be considered as two separate entities, for neither one is of any use without the other. The body is not a machine. Those who look upon it as such make the mistake of feeding it as they would an engine, thinking that it takes so much fuel to keep going. The human organism is perhaps never quite alike on any two consecutive days, for the body changes with our thoughts, actions and environment, and the conditions never quite repeat themselves and therefore we have to readjust ourselves. The most important single item for gaining and retaining physical health is proper feeding, yet the medical men of this country pay so little attention to this subject that in some of our best equipped medical colleges dietetics are not taught. A total of from sixteen to thirty hours is considered sufficient to fit the future physicians to guide their patients in the selection, combination and preparation of food. Dietetics should be the principal subject of study. It should be approached both from the scientific and from the empirical side. It is not a rigid subject, but one which can be treated in a very elastic way. The scientific part is important, but the practical part, which is the art, is vastly more important. A part of the art of feeding and fasting is scientific, for we get the same results every time, under given conditions. When we consider the fact that the body is made up of various tissues, such as connective tissue, blood, nerves and muscles; that these in turn are made up of billions of cells, as are the various glandular organs and membranes; that these cells are constantly bathed in blood and lymph, from which they select the food they need and throw the refuse away, we must marvel that an organism so complex is so resistant, stable and strong. All articles of good quality are made by first-class workmen from fine materials. However, many people fail to realize that in order to have quality bodies they must take quality food, properly cooked or prepared, in the right proportions and combinations. If we feed the body properly, nature is kind enough to do good constructive work without any thought on our part. You will find no rigid rules in these talks on diet, but you will find information that will enable you to select foods that will agree with you. People may well disagree on what to eat, for there are so many foods that a person could do without nine-tenths of them and still be well nourished. In fact, we consume too great a variety of food for our physical well-being. Great variety leads to overeating. A healthy human body is composed of the following compounds, in about the proportions given: Water, 60 to 65 per cent. These substances are very complex and well distributed throughout the body. They are composed of about sixteen or seventeen elements, but a pure element is very rarely found in the body, unless it be a foreign substance, such as mercury or lead. About 70 per cent of the body is oxygen, which is also the most abundant element of the earth. Then in order of their weight come carbon, hydrogen, nitrogen, calcium, phosphorus, sulphur, sodium, chlorine, fluorine, potassium, iron, magnesium and silicon. Because it will be helpful in giving a better idea of the necessity for proper feeding, I shall devote a few words to each of these elements. Oxygen is a colorless, tasteless, odorless gas, forming a large part of the atmospheric air, of water, of the earth's crust and of our foods. It is absolutely essential to life, for without oxygen there can be no combustion in the animal tissues, and without combustion there can be no life. The union of oxygen with fats, carbohydrates and proteins in the body results in slow combustion, which produces heat and energy. Our chief supply of oxygen comes directly from the air, but this is supplemented by the intake in food and water. Carbon is the chief producer of energy within the body, being the principal constituent of starches, sugars and fats. It is what we rely on for internal heat, as well as for heating our dwellings, for the essential part of coal is carbon. The carbonaceous substances are needed in greater quantity than any other, but if they are taken pure, they cause starvation more quickly than if no food were eaten. This has been proved through experiments in feeding nothing but refined sugar, which is practically pure carbon. Salts and nitrogenous foods are essential to life. Hydrogen is a very light gas, without odor, taste or color. It is a necessary constituent of all growing, living things. It is plentifully supplied in water. All acids contain hydrogen and so does the protoplasm of the body. Nitrogen is also a colorless, tasteless, odorless gas. It is an essential constituent of the body, being present in all compounds of protein. It is abundant in the atmospheric air, from which it is taken by plants. We get our supply either directly from vegetable foods or from animal products, such as milk, eggs and meat. Calcium is needed principally for the bones and for the teeth, but it is also necessary in the blood, where it assists in coagulation. We get sufficient calcium salts in fruits, grains and vegetables, provided they are properly prepared. The conventional preparation of the food often results in the loss of the various salts, which causes tissue degeneration. If the supply of calcium in the food is too small, the bones and the teeth suffer, for the blood removes the calcium from these structures. Growing children need more calcium proportionately than do adults. This is without doubt the reason pregnant women suffer so much from softening of the teeth. They are fed on foods robbed of their calcium, such as white bread and vegetables that have been drained. Phosphorus in some forms is a poison whether taken in solid compounds or inhaled in fumes, producing phossy jaw. In other forms it is indispensable for bodily development. The compounds of phosphorus are present in fats, bones and protein. In natural foods they are abundantly present, but when these foods are unduly refined, or are soaked in water which is thrown away, much of the phosphorus is lost. We get phosphorus from milk, eggs, cereals, legumes and other foods. Of course, there is phosphorus in fish, but those who eat sea food to make themselves brainy will probably be disappointed. Phosphates are necessary for brain development, but those who eat natural foods never need to go to the trouble of taking special foods for the brain. If the rest of the body is well nourished, the brain will have sufficient food, and if the body is poorly nourished the brain will suffer. Sulphur is present in protein and we get a sufficient supply from milk, meat and legumes. The element sulphur is quite inert and harmless, but some of its acids and salts are very poisonous. Sulphur dioxide is freely used in the process of drying fruits, as a bleacher. In this form it is poisonous, and for that reason it would be well to avoid bleached dried fruits. We need some sulphur, but not in the form of sulphur dioxide or concentrated sulphurous acid, both of which are used in the manufacture of food. Sodium, in its elementary state, which is not found in nature, is a white, silvery metal. It is found in great abundance in the succulent vegetables, and is present in practically all foods. As sodium chloride, or common table salt, it is taken in great quantities by most people. Those who have no salt get along well without it, which shows that it is not needed in large amounts. If but a little is added to the food, it does no perceptible harm, but when sprinkled on everything that is eaten, from watermelons to meat, it is without doubt harmful. By soaking foods, they are deprived of much of their soda: The two sodium salts that are very abundant are sodium chloride, or common salt, and sodium carbonate, generally called soda. Chlorine is ordinarily combined in our foods with sodium or potash, forming the chlorides. It is essential to life. He who gets enough sodium also gets enough chlorine. In its elementary form it is an irritating gas, used for bleaching purposes. Fluorine is present in small quantities in the body, appearing as fluorides in the bones and teeth. It is supplied by the various foods. In its elementary form it is a poisonous gas. Potassium is found in the body in very small quantities, but it is very important. It is mostly in the form of potassium phosphate in the muscles and in the blood. It is necessary for muscular activity. It is found in most foods in greater abundance than is sodium, which indicates that it plays an important part in development. Like sodium, it is easily dissolved out of foods which are soaked in water, and this is one of the reasons that vegetables should not be soaked and the water thrown away. It is very peculiar in its metallic state, being a silvery metal, very light in weight, which burns when thrown upon water. That is, it decomposes both itself and the water with the liberation of so much heat that it fires the escaping hydrogen, which burns with a violet flame. Pure potassium is not found in nature. Iron is found in very small quantities in the human body, but it is absolutely essential to life. Animals deprived of iron die in a few weeks, and people will do the same under similar circumstances. Iron is obtained principally from fruits and vegetables, but it is also present in other foods. Man can not make use of inorganic iron. He has to get his supply from the vegetable and animal kingdoms. The giving of inorganic iron is folly and helps to ruin the teeth and the stomach of the one who takes it. In the form of hemoglobin this element is the chief agent in carrying oxygen from the lungs to the tissues of the body. In the manufacture of foods, much of the iron is lost. For instance, whole wheat flour contains about ten times as much iron as does the white flour. Too little iron causes, among other ills, anemia, and if the iron is very low, chlorosis or the green sickness may ensue. Magnesium is found principally as phosphate in the bones. It is present both in animal and vegetable foods. Its function in the body is not well understood, but it appears to assist the phosphorus. Silicon is found in traces in the human body. It is supplied in small quantities in nearly all of our foods, and therefore we must take it for granted that it is necessary, although we are in the dark as to its uses. It is very abundant in various rocks. The cereals are especially rich in silicon. In wheat it is found in the bran and is removed from the white flour. The elements mentioned are the most important in the body, though others are found in traces. We do not find the elements present as elements, but in the form of very complex compounds. Under our present conditions of living, we generally partake of too much carbonaceous and nitrogenous food, and get too little of the salts, except sodium chloride, which is taken in too great quantity. Salt, to most people, means but one thing, sodium chloride or table salt. However, there are thousands of salts, and when salts are mentioned in this book, all those necessary for the processes of life are meant, whether they be compounds of fluorine, sulphur, phosphorus, calcium, iron or magnesium or other metals and minerals. Salts are not usually classified as foods, but they are essential to life. Supply the body with all the protein, sugar, starch and fat that it requires, but withhold the salts, and it is but a question of a few weeks before life ceases. This is why it is so important to improve our methods of cooking. A potato that is peeled, soaked in cold water and boiled, may lose as much as one-half of its salts, according to one of the bulletins sent out by the U. S. Department of Agriculture. Other vegetables not only lose their salts by such treatment, but as high as 30 per cent of their nutritive value. The lesson we should learn from this is that ordinarily if it is necessary to soak foods, such as beans, they should be cooked in the water in which they have been soaked. Furthermore, where possible, as it is with nearly all succulent vegetables, we should take the fluid in which the vegetables have been cooked as a part of the meal. If the vegetables are properly cooked, there will not be much fluid to take. To pour away the water in which vegetables have been cooked means that perhaps one-third of the food value and one-third to one-half of the valuable salts are lost. Why continue impoverishing foods in this way? Dr. Charles Page deserves much credit for calling our attention to this fact when most healers neither thought nor talked about it. Now all up-to-date healers with a knowledge of dietetics realize how important it is to give good food. For those who wish more detailed information on the composition of the salts, I insert a table which was compiled by Otto Carque and published in "Brain and Brawn," February, 1913. Those who wish still more detailed knowledge can find it in volumes on food analysis and in some government reports. MINERAL MATTER IN 1000 PARTS OF WATER-FREE FOOD PRODUCTS. Please remember that most of the salts must be worked into organic form for us by vegetation, and that we are able to take but few elements that have not been thus elaborated. We need a moderate amount of food to maintain the body in health, but we should be careful not to overindulge. Perhaps the most injurious errors are made by people who eat because they wish to gain in weight. They consider themselves below weight and they try to force a gain by overeating. This is a serious mistake and leads to much suffering. There is no weight that can be called ideal for all people. To get a basis, I copy a table from the literature of an insurance company. This is for people twenty years old: Height Weight If the weight is much above this, it is a sure sign that the individual is building disease. It may be Bright's disease, fatty heart, arteriosclerosis, cancer or any other ill. The muscles can not be increased in size very much by eating and there is a limit to the amount of fluid that can be stored away. Stout people generally carry about a great amount of fat. Excess of fat is a burden. It replaces other tissues and weakens the muscles. It overcrowds the abdominal and thoracic cavities, thus making the breath short and the working of the heart more difficult, also producing a tendency to prolapsus of the various abdominal organs. People make the mistake of thinking that stoutness indicates health. It indicates disease. Going into weight is going into degeneration. Women like to be plump for various reasons, some of which are not the most creditable to either men or women. Fat people are not good looking. There is not a statue in the world sculptured on corpulent lines that is considered beautiful. It is natural for some people to be slender and for others to be rather plump, but fatness is abnormal. Rolling double chins and protruding abdomens are signs of self-abuse in eating and drinking. As a rule women are at their right weight at twenty and men at twenty-two or twenty-three. This weight they should retain. If twenty or thirty pounds are added to it life will be materially shortened. Perfect health is impossible for obese people, but it is within the reach of lean ones. In getting well, it is often necessary to become quite slender, but after the system has cleansed itself, it gains in weight again. It may take from several months to several years to obtain a normal weight after the ravages of disease. A healthy body is self-regulating and will be as heavy as it ought to be. Those who eat too much in order to gain weight sometimes wreck their digestive and assimilative powers to such an extent that they lose a great deal of weight, and the more they eat the more they lose. Then it is necessary to reduce the food intake until digestion and assimilation catch up with supply. Then if the eating is right the individual goes to the proper weight and retains it. The slender people are in the safest physical condition. The vast amount of statistics gathered by the life insurance companies bears this out. Remember that fat is a low grade tissue, which sometimes crowds out high grade tissue, that an excess indicates degeneration and that obesity is a disease. All fat people eat too much, even though they consider themselves small eaters. They should regulate their eating and drinking so that they will return to a normal weight. This is the only safe way to reduce. Pay no attention to underweight. Eat what the body requires and is able to digest and assimilate, without causing any inconvenience. The organism will take care of the rest. To attempt to force weight onto a body at the expense of discomfort, disease, reduced efficiency and premature death shows poor judgment. Losing weight does not matter at all if there is no discomfort or disease. It is all right to be a little lighter during summer than in winter. In discussing food and its use, two words are frequently employed, digestion and fermentation. Strictly speaking, digestion is largely a process of fermentation, consisting of the breaking down of complex substances into simple ones, by means of ferments. However, in the popular mind digestion and fermentation are not synonymous, and will not be so considered in this book. To make my meaning clear, in this book the words will have the following meaning: Digestion—the normal breaking down of food and formation into substances that can be used by the blood for building, repairing and producing heat and energy. Fermentation—the abnormal breaking down of food in the digestive tract, producing discomfort and health impaired. This process manifests in various ways, such as the production of much gas in the digestive tract or hyperacidity of the body. We will consider digestion as a process conducive to health, but fermentation, as one that leads to disease, being an early stage of digestive derangement. |
