A growing child is usually hungry when it returns from school, and it is well to give a little easily digested food regularly at this time, but not sufficient to destroy the appetite for the evening meal. Irregular eating between meals, however, should be discouraged. An egg lemonade is easily digested and satisfying. If active and exercising freely, craving for sweets should be gratified to a limited extent. The growing boy or girl takes from six to eight glasses of water a day. Overeating, however, should be guarded against for many of the dietary habits of adult life are formed in this period, and the foundation of many dietetic difficulties and disturbances of the system are laid. If one is not hungry at meal time, the chances are that he is not exercising sufficiently in the fresh air. _Thorough mastication should be insisted on._ One should encourage the habit of eating hard crusts or hard crackers to exercise the teeth and to insure the swallowing of sufficient saliva. The schoolboy or schoolgirl, anxious to be out at play, is especially liable to bolt the food or to eat an insufficient amount. This should be especially guarded against and parents should insist on the proper time being spent at meals. The dislike for meat or for certain vegetables or articles of food, which develops in this period, should be guarded against. All wholesome food should be made a part of the diet and the child should not be indulged in its likes or dislikes, but should be instructed in overcoming these. Very few foods disagree at all times with a normal child and if they do the cause usually lies in a disordered digestion which needs to be restored by more careful attention to exercise, deep breathing, and to elimination of the waste of the system. * * * * * [Sidenote: The Athlete] The young man active in athletics needs practically the same food as given in Diet IV, yet more in quantity. He needs to drink water before his training and at rest periods during the game. If he is too fat, he should train off the superfluous amount by exercise and by judiciously abstaining from much sugars, starches, and fats. Diets for reduction, however, must be governed by the condition of the kidneys and the digestive organs. Deep breathing habits are imperative though he must be careful not to overtax lungs or heart by hard continuous straining, either at breathing or at exercise. * * * * * [Sidenote: The Laboring Man]
