Great info. I've been eating similar to paleo for years by avoiding the inner aisles of the grocery store. I also have a great disgust for overly processed food. If it will keep for a month, it's not going in my body. My question is this - what is the drawback to grain and legumes? I know they all require modification form their original form (you cant gnaw on raw oats, they must be rolled first). That is my only question about Paleo, I am on board with everything else.
