Those who accustom themselves to a rich, stimulating diet, find after a time that the stomach is not satisfied with simple food. It demands that which is more and more highly seasoned, pungent, and stimulating. As the nerves become disordered and the system weakened, the will seems powerless to resist the unnatural craving. The delicate coating of the stomach becomes irritated and inflamed until the most stimulating food fails of giving relief. A thirst is created that nothing but strong drink will quench.
Self-Control the Safeguard
It is the beginnings of evil that should be guarded against. In the instruction of the youth the effect of apparently small deviations from the right should be made very plain. Let the student be taught the value of a simple, healthful diet in preventing the desire for unnatural stimulants. Let the habit of self-control be early established. Let the youth be impressed with the thought that they are to be masters, and not slaves. Of the kingdom within them God has made them rulers, and they are to exercise their Heaven-appointed kingship. When such instruction is faithfully given, the results will extend far beyond the youth themselves. Influences will reach out that will save thousands of men and women who are on the very brink of ruin.
Diet and Mental Development
The relation of diet to intellectual development should be given far more attention than it has received. Mental confusion and dulness are often the result of errors in diet.
It is frequently urged that, in the selection of food, appetite is a safe guide. If the laws of health had always been obeyed, this would be true. But through wrong habits, continued from generation to generation, appetite has become so perverted that it is constantly craving some hurtful gratification. As a guide it can not now be trusted.
Nutrient Value of Foods
In the study of hygiene, students should be taught the nutrient value of different foods. The effect of a concentrated and stimulating diet, also of foods deficient in the elements of nutrition, should be made plain. Tea and coffee, fine-flour bread, pickles, coarse vegetables, candies, condiments, and pastries fail of supplying proper nutriment. Many a student has broken down as the result of using such foods. Many a puny child, incapable of vigorous effort of mind or body, is the victim of an impoverished diet. Grains, fruits, nuts, and vegetables, in proper combination, contain all the elements of nutrition; and when properly prepared, they constitute the diet that best promotes both physical and mental strength.
