Nutrition 101: Dr Gregers annual nutrition summaries, How Not To Die

Dr Greger is an internationally recognized expert in the field of nutrition. He created the website and youtube channel Nutritionfacts.org and he wrote the New York Times bestseller 'How not to die'. Every year he gives a presentation summarizing the latest in nutrition research and current understanding of the effects of nutrition on medical diseases.
His talks are absolutely brilliant and eye-opening,  The common theme circles around the benefits of a plant-based diet and how it can reverse and be used in the prevention of many diseases. (heart disease and diabetes just to name a couple.)
I think physicians and future doctors everywhere should watch his videos.
Here are the videos for the annual talks below:
