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 science communication This website is incredibly helpful for navigating the confusing world of nutrition science. Dr Gregor is a brilliant communicator as he explains scientific studies in a way that the general public can understand. He just lays out the evidence for us so we can make informed decisions. I do have a background in science and I read scientific papers for fun and I've checked on his sources to make sure he was communicating them accurately. He is one of the only nutrition doctors that I trust as most are just making content will sell for profit. The website is non-commercial and non-profit as well as his books (all proceeds are donated to charity!) and Daily Dozen app. I've been using this site for years now and it's been so helpful for making sound nutrition decisions. No more fad diets!

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.

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.
