If we want to examine the diet of cavemen they were constantly active by participating in hunting and gathering or running away from the larger animals. It’s important to remember that you don’t have to outrun the bear, just the other person that’s running away from the bear as well =) because the slow fat one will probably pass out sooner and become lunch while you get away.

That said there are some benefits to the paleo diet or raw food diets but I think the idea behind it is more important. Specifically, cutting down on the foods that involve a lot of processing and preservatives.

Case and point, if the chicken nugget you’re eating doesn’t look like a chicken and still tastes great there’s reason to be concerned.
