Critical Review of Michael Greger’s “How Not to Die”


In an alarming and unforeseen plot twist, I have written two blog posts in one month.

This one’s a review of plant-based-diet advocate Michael Greger’s book, “How Not to Die.”  Enjoy!

“How Not to Die” by Dr. Michael Greger: A Critical Review



  1. Congrats to you Denise, the most courageous investigator out there. Thanks for including me on your emailing list. I always tell people about your book (Death By Food Pyramid) which is such an important cog in the nutritional science machine. I say courageous because you are so intrepid going up against so many researchers who develop vested interests in maintaining their sometimes inflexible claims. So glad to see you are still out there doing it. You wouldn’t believe the arguments I have gotten into at the local “Plant Based” restaurant in Santa Rosa CA ( the only one around) where a group of “How Not To Die” fans hold regular “meetings” with book in hand. ha ha. I try to tell them about your book and the sensible flexibility beyond their horizons. Such dogma is always out there with “true believers” in just about anything…..

    1. Myron: sorry to hear about your bad experience with some vegans, i do hope you won’t paint all of us with the same brush. I actually subscribed to Denise’s blog after hearing of her review of ‘The China Study’, because I like to see opposing critiques of vegan information sources, and judging for myself based on the strength of the evidence.

      To your point about ‘sensible flexibility’, Dr. Greger himself even says that there’s no evidence of harm for very little meat consumption, on his book and on his website, he’s very clear about that. He does make a good point though, that food is a package deal, and since there aren’t any animal-product-only essential nutrients, you can generally find the nutrients you need in a healthier source, or at least one with fewer drawbacks.

  2. Good review, Denise. I was curious about phytates, so did a bit of research. Dr. Weil says bad only for wheat-bran junkies, good in anti-inflammatory effects and lowering glycemic load. Dr. Harland says they may result in marginal mineral deficiencies, but that there is evidence that they may have beneficial effects. Heal Yourself At Home has a lot of information about phytates. When I was a WAPF member I pretty much bought everything. I no longer buy much of what passes for dietary advice unless I’ve thoroughly researched it. I no longer eat grains, and I no longer soak nuts (except pumpkin seeds, which I really like the Aztec way, with chile). So phytates occur in all plants; it is how they store some minerals. What’s not to like about that? In a reasonably wholesome diet they’re unlikely to be unhealthful for most people, and the contrary may be true. That’s my take, anyway.

  3. Sounds like “cherry picking” is pretty kind for some of these examples, which look more like flat out lies to me.

    Good information about viral and bacterial diseases from undercooked pork, though – I’d been starting to cook my pork less given lower trichina concerns, but it sounds like there are other reasons not to eat pork rare.

  4. Hi Denise. I had wondered where you had gone.If this is indeed you I am glad you are still on the scene. RCY

  5. Great review! I love your balanced and holistic approach, your reviews are definitely fodder for thought. And I might just have to retrain myself a bit: only use the grill for veggies, and slow cook any meat on low temperatures. Or eat it raw (unless it’s pork or chicken, naturally).

  6. Have you spotted any cherry-picking in chapters about heart decease and high blood pressure? For me they sound very convincing​ to restrict animal products to very few times per month.

  8. Interesting report from Kansas State that black pepper, like herbs from the mint and myrtle family, can reduce HCA production in grilled meats to very low levels.

  9. So far I’ve purchased four copies of “How Not to Die” for myself and my relatives. Unfortunately, they seem to be too set in their habits to benefit very much from the information. At any rate, it makes me feel better that I tried to share the knowledge. In defense of low fat part two, please. Cheers!

  10. Ah, thank you! I’ve been looking forward to another post. I’m curious if you dare adventure into the Saturated Fat controversy surfacing again? I’d love some clarity around these claims.

  11. Please tell me, you’re going to write something about the new American Heart Association Guideline to dietary fats…they’re outright claiming that saturated fat causes heart disease (even coconut oil!) and we should consume polyunsaturated fats only. And supposedly they are basing this claim on the newest science and studies…but if it’s not true….how can highly qualified people like that not see the flaws in studies you see? They are not just some quacks with a youtube channel, after all. And I just can’t believe they would knowingly spread false information. My head is going to implode any day now 😦

  12. Hey Denise, I’m eagerly awaiting your follow up to your low-fat-high-carb blog post you did almost two years ago(?). I’m guessing you’re now writing a book with a similar theme instead of a blog post? I can’t think of why you’d delay writing/posting the second part seeing how sound and popular the ideas spread around the blogosphere. Looking forward to it either way!

  13. Like every other food-centric approach this book is a waste of time.

    The way not to die is to have high HDL, muscular thighs, a reasonable waist line and low systolic blood pressure. All those markers are improved most by exercise. Unless you stuff your face with too much food and get fat, ANY macro will do.

    Think Jack Lalanne and Ancel Keys as the standard. It’s a HUMAN condition. A pot of collards is not a human.
