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

Excellent source for a clear overview of the current science. Logical, plain language reviews of published science. Asks the right questions. Critically evaluates the studies on each topic.You can see the original studies for yourself. When conclusions can’t be drawn, he says so. Practical and useful. Unbiased.

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.

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.

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
