It seems I recall 2kd episode where a guest discussed a comparison of traditional native diets around the world and the affects of modern western food on the health of their children as it became popular. Any links on this question?

I really enjoyed this video of Dr. Pradip Jamnadas. It may not be what you are thinking of, but very inspiring and he discusses the paleo diet vs current eating habits.
