Life changing Hilarious that the negative reviews state that he doesn't site sources. His organization and book goes through literally tens of thousands of studies every year.

Brilliant evidence based nutrition! I have applied most of Dr Greger’s findings to my own life with great success. I have no heart disease, type 2 diabetes and am living an enjoyable life. His videos are brilliantly thought out.

Mediterranean or Icelandic diets give longevity. As a scientist myself, this "research" is biased. Arguing for a plant only diet as a cure all, is misunderstanding human metabolism and claiming something it cannot deliver. If you only eat plants you will have to supplement with Vit B12, iron and certain amino acids. Eating a mediterranean, Japanese or Icelandic diet has far more evidence of longevity.

Poor science Poor, unsupported scientific conclusions lacking causation. It appears somewhat ideological to me.
