What an animal naturally eats is decided by instinct, and instinct here is preference, and the ability to obtain what it needs. A cat is not able to eat chestnuts, nor does it care at all for the taste or flavor of chestnuts; a squirrel, on the other hand, has the claws and teeth with which to open and eat chestnuts, and it finds them quite delicious as well. But how about human beings? Extremely clever and arrogant as they are, human beings ignored the laws that governed what they should eat. Learning how to use utensils, fire, and various seasonings, they were able to eat things which, originally, they could not eat, or should not eat. The things human beings desire and can obtain and eat without the use of tools or fire are, for example, nuts and fruit, plants, seeds, potatoes, small fish, and eggs (if you give a monkey an egg it will skillfully break the shell and suck out the contents -- monkeys and human beings naturally eat the same things). So it is that, no matter how much of a brave and strong Tarzan one is, it is probably quite impossible to catch and butcher bovine animals and whales with one's bare hands. The Human Diet: Crime and Punishment By the use of utensils, fire, and seasonings human beings changed their natural diets, thereby increasing almost limitlessly the things they can eat, and by transforming themselves into hunting, eating animals, have increased their numbers dramatically. On the other hand, however, they weakened themselves physically. Not only that, they also process their natural foods with heat and seasonings, thus killing the life within their food, destroying the cells, and substantially decreasing the beneficial effects of the food. Thus if we do not stuff our bodies full we cannot get enough nutrition, and this has brought about the transformation of the human being into the greatest eating animal on Earth. Note first of all that human beings suffer serious tooth decay, something we don't see much in wild animals. We catch colds all the time. We are troubled by chronic digestive disorders (only humans use bathroom tissue; if an animal is healthy its excrement will not stick to its body). We perspire profusely (since perspiration is a means of getting rid of wastes, sweating a lot is proof that one's body is full of sewage; no matter how hot it is, one should perspire only moderately). And in recent years we have come to live in fear of chronic illness brought on by the compound effects of many chemical substances that are foreign to our bodies. Though the net of Heaven is course, it has not overlooked the human rebellion against our natural diet. The fact that human beings have barely managed to survive in spite of this is due to the fact that we have continued, as we should, to consume some fruit and vegetables raw. Raw vegetables with meat, pickled vegetables with white rice, and fruit for dessert. Our Modern Diet has Brought about Sickness and the Weakening of Our Bodies
