3 Well known MD’s debate the 3 diets. Worth a watch. I tend to believe any diet based on whole natural foods is always the way to go. Vegetarianism is OK but the biggest issue with full Vegan is the brain changes due to a lack of certain Essential Fatty Acids. (This is why many full Vegans are a bit…. odd). Versions of a Paleo based diet are the healthiest for the majority of the American population.
