Nowadays, some so-called doctors are still very inclined to the old theory that people need meat to survive. But you can find plenty of books using research from other scientific work, and many other doctors who say that meat protein is harmful, toxic and bad for the body. And they have proven a thousand and one percent of it. So don't listen to one theory alone and be convinced about it. We don't need a meat diet, not at all. No one needs it. Actually, many people are cured of sickness after beginning a vegetarian diet. Is that courageous enough instead of listening to the other theory? We can be hypnotized into believing in one type of theory and convince ourselves of that theory, and then believe that meat is essential to us. But it's not true.
