Actually, our digestive systems are SET UP for eating meat, raw or otherwise. It is vegetable matter, plant material, that we cannot get the full nutrition from without cooking to break down the cell wall. Cows have ruminant stomachs which is how they do it. We have only one stomach of 1 chamber, not 5 like a cow, and don't chew our cud. BUT, we are "smart" (other than vegans, anyway) and figured out how to COOK vegetables as well as meat. It's how I can eat pork without getting parasites. I'll kill it, then grill it, myself.
Another thing, there are two amino acids (building blocks of proteins) that can only be had in meat and soy. This is why vegans love tofu...
Without those two amino acids, one will be mal-nurished in short order. Vegans often take supplements for the things they don't get in their diet for the lack of meat. Just how "natural" is THAT, eh?
I'd hang out with someone that has brains, other hunters for instance. You don't want to start absorbing too much stupidity, right?
Carnivores are ALWAYS smarter in nature than the prey animals, ya know. I have a T shirt somewhere that says, "Vegetarian ... Ve-ji-tear-y-an....A native American word for "bad hunter"" I don't know what I did with that T. It was getting holey I wore it so much, might have tossed it.
