Vitamin B12 supplements What page of ' How Not To Die " early version , refers to the importance of taking Vitamin B12 supplements?

The best health advice I have ever… The best health advice I have ever experienced. It is evidence-based, easy to absorb and not profit driven

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.

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

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.
