Also, I have heard some people try to link paleo to evolutionary ideals, but you have to look at the big picture; it's a healthy way of eating, not a faith or religion. Adam may have been a farmer, but I'm going to guarantee that he wasn't using roundup or glyphosphates, which are two carcinogenic chemicals sprayed on our grains today. It's not a problem with grains in and of themselves, it's the quality of 90% of the grains in America.
