Cherry-picked information and misrepresented studies Dr Greger has an inherently religious or cult-like bias to a certain diet. He has a tendency to completely dismiss other diets (eg. FODMAP), despite there being a lot of sound scientific information behind them. While he has some good information and is very good at communicating it, he selectively ignores information which does not back up his viewpoint. His website should really be called ‘cherry-picked nutrition facts’. Greger's overall M.O. is that he uses lots of observational studies (which are considered low-tier evidence because of the correlation/causation problem) linking an animal food to a health problem, but if the same studies find a positive or neutral result for a different animal food, or a negative result for a plant food, he just ignores it. When diets low in animal foods produce health, he also uses these findings to shill for veganism (no animal foods at all), while using the nebulous weasel word "plant-based." Anyone following his diet must take daily B12 supplements to stay healthy - the reason being, he has removed every single natural source of B12. If you need to take nutritional supplements, then your diet is deficient in the nutrients it needs to survive and thrive - pretty simple. There are plenty of other safer diets out there that have been well researched that will improve your health. Talk with your dietician or nutritionist. His advice should be taken with a grain of salt and a good dose of caution.

Truly life-saving information Truly life-saving information, for free. He doesn't sell anything. I made a donation because he had a very obscure chart in a YouTube video that proved that my Western MD's were wrong. Thank you, Dr. Greger. You, and Abraham Hicks, and some true friends, saved my life. Dr. Greger's 20 researchers comb through the 100K English medical studies published annually to bring to gist of it, to lay people, in a way that we can easily understand. Brilliant. See Dr John MacDougal (sp?) or McDougal also for similar longevity info.

Half-truths at best Mostly unsubstantiated claims, intent on misleading people by stating half-truths and omissions of important information.

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.
