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

Truth about arsenic was precious. I am at Weimar University studying under Dr Neil Nedley and a collection of distinguished practitioners. I have been on a plant-based diet for 40 years and find my experience matches the science on this channel and the research presented in classes here. And the research on arsenic and turmeric is super. (Who that scientist is who said in a review that persons eating like like me need supplemental iron, b12, and aminos, I don't know. But his opinions are so outdated. And plant-based diet rich in vegetables has all the aminos needed.

Excellent resource for nutrition info Excellent resource for nutrition info. Meticulously presented with double-blind, placebo controlled research. Love sharing these bite-size video's. My only complaint is Dr. Greger's contrived speaking style and including his mug in every video - unnecessary.

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.
