Those articles seem to be advocating against the idea (popular in the paleo community) that carbs are unhealthy or wouldn't have been part of our ancestral diets. I agree that idea seems mistaken, and agree that fruit, tubers, and honey are all foods we've likely been eating since aproximately forever. But I don't think it's true we weren't also eating a lot of animals, and in many cases, getting most of our calories from animals. Separately, the existence of modern hunter-gatherer groups like the Hadza that eat a lot of meat and are healthy suggests eating meat is healthy. (Of course, you have to be careful, since there are potentially large differences between the Hadza's nose-to-tail fresh, wild kills, and what you might get at the supermarket. Meat is a broad category.)
