Simplicity and naturalness are great aids in breaking away from food slavery. They are discussed more fully elsewhere. In the next chapter will be found hints on the solution of the normal amount of food to be eaten. CHAPTER V. DAILY FOOD INTAKE. It is generally believed that the more we eat the better. Physicians say that it is necessary to eat heartily when well to retain health and strength. When ill it is necessary to consume much food to regain lost health and strength. "Eat all you can of nourishing food," is a common free prescription, and it sounds very reasonable. The physicians of today are not to blame for this belief in overeating, for they were taught thus at college, and very few men in any line do original thinking. It has been a racial belief for centuries and no one now living is responsible. When a physician advocates what he honestly believes he is doing his best, "and angels can do no more." When a child loses its appetite, the parents worry, for they think that it is very harmful for young people to go without food for a few meals. A lost appetite is nature's signal to quit eating, and it should always be heeded. If it is, it will prevent much disease and suffering and will save many lives. The present-day mode of preparing food leads to overeating. The sense of taste is ruined by the stimulants put into the food. Dishes are so numerous and so temptingly made that more is eaten than can be digested and assimilated. Refined sugar, salt, the various spices, pickles, sauces and preserves all lead to overeating because of stimulation. The same is true of alcohol taken immediately before meals. If we only give nature a chance, and are perfectly frank and honest with ourselves, she will guard us against the overconsumption of food. Those who eat but few varieties of plain food at a meal are not sorely tempted to overeat. But when one savory dish is served after another it takes much will power to be moderate. People generally have had more than sufficient before the last course is served. However, the various dishes have different flavors and for this reason the palate is overwhelmed and accepts more food than is good for us. Men who like to call their work scientific, figure on the amount of food we need to furnish a certain number of heat units--calories. Heat, of course, is a form of energy. Basing the body's food requirements on heat units expended does not solve the problem. The more food that is ingested, the more heat units must be manufactured, and often so much food is taken that the body is compelled to go into the heating business. Then we have fevers.
