In these days of increased destruction and decreased production of human foods, it is of great importance to know how to secure a maximum amount of nutrition from a minimum expenditure of money. The world is facing a food shortage that in some places has assumed the proportion of the gaunt specter of famine. In view of this fact, it is well to remember that flesh is the most costly source of food. Sixty-two per cent of the best beefsteak is water. Flesh foods contain but twenty-five per cent nourishment, and seventy-five per cent waste matter. The grains contain seventy-five per cent nourishment, and but twenty-five per cent waste. Now it does not require a knowledge of higher mathematics to determine that since ten pounds of grain, when fed to an animal, make but one pound of flesh, the latter becomes a very costly source of our food supply. _9. The Testimony of Anatomy and Physiology_ Even a kindergarten study of the structure of the human body reveals the fact that man was not intended to be a carnivorous, a herbivorous, or an omnivorous animal, but rather a frugivorous creature. He does not possess the rough, raspy tongue of the cat family, the long, pointed canine teeth of the lion, the sharp claws of the tiger, or the talons and hooked beak of the eagle. In the carnivora, the alimentary canal is very short, being only three times the length of the body. In herbivora, as the sheep, it is thirty times the length of the body. In frugivora, such as apes, monkeys, and man, it is twelve times the body length. Baron Cuvier, a famous anatomist, writes, "The natural food of man, judging from his structure, appears to consist principally of the fruits, roots, and other succulent parts of vegetables." _10. Flesh and Morals_ The menu provided for man in the beginning did not include animal food. Not until one thousand six hundred fifty-six years of human history had passed was man permitted to eat flesh, and then only after every green thing had been destroyed by the Deluge. What we eat exercises a profound influence upon what we are, how we think, and how we feel. Let us divide the animal kingdom on the basis of diet and disposition. On the one hand, we have the lion, the tiger, the wolf, the bear, the leopard, the panther, etc.; all these are vicious, snarly, crabbed, ferocious beasts. What comprises their diet? We call them "beasts of prey." They feast upon the bloody, quivering flesh of their victims. On the other hand, we might mention the horse, the ox, the deer, the sheep, the elephant. Think of their dispositions, calm, quiet, pacific, easily domesticated. May it not be that their diet of cereals and herbs contributes to their peaceful temperament?
