We have way less acidity in our stomach than carnivore animals, and we have teeth which don't have the right form and size and distance from one another, and our intestine is way too long, and there meat is bound to become putrescent. That we don't have enough acidity in the stomach is a problem on how to deal with the parasites also, of which meat is loaded. Carnivore animals mainly kill these parasites in their stomach, while we can't. If you count on going so much on raw meat, you'll be loaded with them. All and all, one can say that for sure our digestive system is not conformed for such a diet. Amen
