Can't argue with facts One of the best - if not THE best - nutrition sites on the internet. Evidence-based, they cite all of their findings. It is clear a LOT of work and research has gone into bringing this to us. Very impressed

The information presented stays current with the latest published studies The information presented is based on current science. While the primary conclusion is that a vegan promotes better overall health and can aid in preventing illness. As new studies arise, recommendations can and have changed, even if they contradict prior advice. This willingness to avoid a dogmatic approach is helpful in our quest for better health.

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.

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. I can only assume the negative reviews come from biased employees of certain industries, or they've never actually read a single thing he has written and are just turned off my having to face the reality that what they are eating is probably killing them.
