This Weird Diet Is Actually The Healthiest, According To One Of The Country's Top Functional Docs Introducing the pegan diet. Mark Hyman, M.D., is one of the country’s top functional medicine doctors and a member of the mbg Collective (if you didn’t catch his panel on mitochondria at 2017’s revitalize, it’s a can’t-miss!). ...Ultimately, he concludes that the healthiest way to eat is a play on paleo and vegan: the pegan diet. In this excerpt, he explains exactly what that means. ... The vegan diet, for example, ideally incorporates plenty of whole, plant-based foods. As a result, vegans get lots of vitamins, minerals, antioxidants, fiber, and healthy fats with none of the baggage that comes with feedlot meat. ... But even a perfect vegan diet won’t provide enough DHA and EPA, which are important omega-3 fatty acids. Neither will it provide enough iron, zinc, copper, or vitamin D. Vegans are also unlikely to be getting the amount of quality proteins and essential amino acids they require, especially as they age. It’s possible to find sufficient amounts in non-animal sources, but it is incredibly challenging. But they’re definitely not getting B12 because it only comes from animal foods. ----------- This is the diet I have been following for the last year before they defined it as a 'diet'. I used to be a die hard Meat'atarian however now my diet is almost entirely small amounts of meat or fish along with a ton of veg and nuts and seeds. Very little to no carbs, no sugars that are not natural. I have certainly noticed and feel a difference in my energy and health levels.
