Although humans are capable of digesting meat, human anatomy clearly favors a diet of plant foods. Our digestive systems are similar to those of the other plant-eaters and totally unlike those of carnivores. The argument that humans are carnivores because we possess "canine" teeth ignores the fact that other plant-eaters have "canine" teeth, and that ONLY plant-eaters have molar teeth. Finally, if humans were designed to eat meat, we wouldn't suffer from heart disease, cancer, diabetes, and osteoporosis from doing so.

As for the argument about a certain age being right for being a vegetarian, this statement makes the assumption that protein from plants isn't as good as protein from meat. The truth is, protein is protein. It is all made from amino acids. Children need 10 essential amino acids to grow and develop properly. These amino acids are as readily available in plants as they are in meat.
