Aged persons bear want better than do young ones. Indeed, after middle life abstemious eating should be practised in order to maintain health. During old age less work is done; tissues cease to grow, and repair takes place slowly. The need for food is therefore greatly lessened. It is a common dietetic error at this time to eat too much. Food should be varied, but taken in small portions. When old people are feeble, they should eat four or five times daily. Often because of few and poor teeth old people must live chiefly upon liquid and soft foods. Whenever it is possible their teeth should be repaired or false ones provided that food of all kinds may be eaten. As tissue repair and tissue growth is stopped or reversed, a gradual wasting being the rule in old age, protein foods are not so necessary as in early life. Moreover, they are not so desirable, for often elimination of nitrogenous waste by the kidneys is less perfect. Bland, easily digested foods should be preferred. Foods which are not easily digested will ferment in the gastrointestinal canal and will form toxic substances which increase arterial tension and thereby the work which the heart has to do. The latter organ under these conditions grows weak and is unable to maintain a perfect circulation, a condition which deranges the functions of various organs. This produces ill health and is often the cause of fatal illness. Such stimulating beverages as tea, coffee, and cocoa are well borne and particularly grateful.

In middle life, or, to be more exact, after the thirtieth year, it should be remembered that it is no longer necessary to eat to make more tissues or to promote growth, but only to maintain an equilibrium of weight and strength. At this time the habit acquired in childhood of eating largely is strongly established and the pleasure of eating is most appreciated. Therefore, most men and women are inclined to eat too much and to eat food that is too rich or that, although most palatable, is indigestible. It is at this time that indiscretions of diet are with especial frequency a cause of disease. The quantity of food eaten should vary with the amount and character of one's physical work. When a sedentary life is led, only the most digestible foods should be eaten, and these in moderate amounts.

At this time the habit of eating only what is needed should be acquired and earlier habits should be broken. The average man should limit himself to small portions and should make it his rule not to take more than one portion of any kind of food at a meal. This general rule is subject to modification for many who are doing hard physical work need a somewhat more generous supply than this general rule implies but they should endeavor to vary their eating as their work varies. It is a common observation of physicians that farmers who eat very heartily during the summer when their hard work enables them to digest and utilize it continue the same habit during the winter when work is comparatively light. This results at first in mild forms of indigestion, but ultimately in a chronic gastric disorder.

In infancy and childhood food must be eaten to maintain heat, which is radiated with relatively great rapidity, to supply muscular energy, which in childhood is generously expended; and to supply the great demands that rapid growth of tissues makes during the earliest years of life. The most rapid growth takes place in infancy, when there is the smallest expenditure of muscular energy. The composition of mother's milk, which is nature's especial aliment for this period, gives us a key to the kinds of food needed and to the relative quantity of each required to promote a rapid growth of tissues. It contains from 1 to 2 per cent, of protein, approximately 4 per cent, of fat, 5 or 6 per cent, of digestible carbohydrates, and about'90 per cent, of water. Food of this composition does not make hard, firm flesh or create power to resist disease. These conditions are developed later when the diet is richer in proteins and solids.

From the following table compiled from the more extensive one made by E. A. Locke,1 it will be easy to estimate the protein and caloric value of a meal made up of common foods for the values are given for portions ordinarily served.
