Got an hour? This is well worth the watch if you do. Loren Cordain makes the case for an ancestral (aka paleo or primal) diet in a very accessible way.
Me, I’m with Kurt Harris (and the WAPF folks) that there are good neolithic foods, including dairy. But that’s quibbling around the margins. It’s far more likely that the industrial foods of the last 100 or so years are a bigger problem than those that have been around for 10,000.
Give it a watch and see if you don’t see the usefulness of eating more real, whole foods and less processed, industrial foods.
