The ox, as we know, is able to maintain vigorous strength and perfect on an average of 20% grain and 80% grass, without the use of flesh. The elephant on even less grain maintains good health, gains gigantic strength, and reaches great age. On the other hand, the dog, though carnivorous, cannot maintain good health on flesh alone. Merely by instinct he knows that he has to help himself to grain and to some grass, too. The herbivorous animal never even tastes flesh. These facts prove that a balanced vegetarian diet is complete in itself, but a flesh diet is never complete alone. The only animal that can get by fairly well on flesh, though not altogether, is the one which eats the whole, hide, hair, bones, hoofs, flesh, and all. Man’s intelligence concerning his body’s needs has degenerated lower than that of the dumb animals!” (Houteff 16)
