Im not gonna get into a debate over evolution or religion, but humans are omnivores. We eat everything. To go against it is a hardship upon the body, I personally believe that, jmho...It is proven that animal protiens are utilized more efficiently by the human body. Sure, plant matter can supply some, but it is not as bioavailable as meat. Being a vegan just makes it that much more challenging, then if you got bad genetics, you really shoot yourself in the foot. I believe plants are what food eats...
