The video you post is an odd mix of No-True-Scotsmen with a smattering of strawman, and some outright, “Did you even watch the video you’re criticizing,” level misstatements of her positions. He goes on an on about teeth. She didn’t say humans don’t eat meat. She said we were omnivorous and didn’t spend our distant past eating tons of meat. He practically accuses her of saying we’re herbivores. I hate to break it to you, but it’s not my job to police what Paleo dieting is. If you want to distance yourself from the popular books on the subject that sell very well- you better find another name.
Meanwhile. I hate to put it this way, but we tend to live past forty now. I don’t think gluten has exactly destroyed civilization.
