"An examination of the structure of the human body leads to the conclusion that man is intended by Nature to live on a vegetable diet. There is the closest affinity between the organs of the human body and those of the fruit-eating animals. The monkey, for instance, is so similar to man in shape and structure, and it is a fruit-eating animal. Its teeth and stomach are just like the teeth and stomach of man. From this we may infer that man is intended to live on roots and fruits, and not on meat. (Chapter V, Food)"
