Harvard’s Meat and Mortality Studies

Subscribe for free to Dr. Greger’s videos at bit.ly Donate at bit.ly DESCRIPTION: Monday, March 12, 2012, the Harvard Health Professionals Follow-up Study and the Harvard Nurses’ Health Study concluded that red meat consumption was associated with living a significantly shorter life—increased cancer mortality, increased heart disease mortality, and increased overall mortality. Have a question about this video? Leave it in the comment section at nutritionfacts.org and I’ll try to answer it! Those familiar with the science will not be surprised by the findings of the two new Harvard studies. Remember the NIH-AARP study I profiled in Meat & Mortality (nutritionfacts.org ? Half a million people studied—the largest forward-looking study on diet and health in history—and they found the exact the same thing. If the science is so strong why isn’t it reflected in our dietary guidelines? See Dietary Guidelines: Science vs. Corporate Interests (nutritionfacts.org Nor should it surprise that nuts are so healthy. See Halving Heart Attack Risk (nutritionfacts.org and Is Peanut Butter Good for You? (nutritionfacts.org And speaking of nuts, have you seen the NutritionFacts.org tag cloud? (nutritionfacts.org I have videos on more than a thousand nutrition subjects (nutritionfacts.org For my thoughts on the American Meat Institute’s reaction to the study, see my Care2 post here (www.care2.com Also, please check out my associated blog post: nutritionfacts.org

  1. Thanks for posting this video. The conclusions of the Nurses’ Health Study certainly have the power of a huge number of study members, correction for confounding variables and consistency with known physiology. The fat in meat is clearly the culprit, though, which deserves some mention, since people can remove more of the fat with preparation methods, and they should. Blotting the fat out of a freshly cooked burger removes the bulk of the fat, e.g., and allows substitution of some savory sauce.

  2. Fuck yeah vegetarianism!

  3. GO VEGAN !!!

  4. go vegan!

  5. Bloggers who sells tons of supplements, books, dvd’s, conferences and making money from the views they get on their blog. Selling a diet that no study support, so instead of making studies (which they can’t because they’re not scientist) they tell you to not trust modern science! And then you’ll call the scientist from Harvard dogmatic and propagandist?

    What are they selling? How are they making money from people not eating red meat? They’re not they’re just doing science unlike you bloggers.

  6. I’ve been the last few years trying to find something credible that is in opposition to the enormous amount of scientific litterature showing plant-based eating as the best option and the best I found is associations basing their claims on a book writen by a dentist in the 30′s, or another guy’s study on cats also from the 30′s. And bloggers with no proper training suposely debunking studies done by real scientists, some of the top scientists actually.

  7. Actually, it should be obvious that I do… I’ve read BOTH Campbell’s book AND the actual study data. Have you done the same?

    I’ve also spent nearly 2,000 hours researching this subject to come to my own conclusions, rather than believing whatever anti-meat dogma and propaganda you’ve adopted…

    If you have ANY research disproving anything I’ve said, post it. Otherwise, keep your propaganda to yourself.

  8. Chemical engineering standpoint? How are we ”chemically” forced to eat dead animals? Please explain in details.

  9. Vegans are the group closest to the recommended intake of most nutrients.

  10. You obvisouly don’t know what is the china study…

  11. “The China Study” is a book, not a study. Only a small portion of it is devoted to the actual study, and the portion that is EXCLUDES entire counties worth of data that DISPROVE Campbell’s theories.

    Also most everything Campbell does includes ALL animal proteins/fats as bad, when his actual research was only on Casein.

    Nice try though. His research is incredibly biased and not conclusive. Not even remotely.

    And the book is less-conclusive and more biased than his other research. Propaganda.

  12. Then read the China Study. That researcher grew up on an Iowa farm eating dairy and meat his entire life up until he proved to his own skeptical self that animal protein, in particular casein the milk protein, is a cancer accelerator. He came up with the same results as this study over and over again through 40 years of long term studies on nutrition.

  13. This isn’t even the first such study, not by a long shot. For some people, there will never be enough studies, they will never go long enough for them or have enough people involved. Just like the tobacco industry and lung cancer. I recommend everyone read The China Study. No one can come after that scientist no matter how hard they try. He did too many studies for too long and the same results keep coming up – and this Harvard study came to all the same conclusions.

  14. Protein content of some plants

    Soy : 35-40%
    Hemp (seeds) : 30-35%
    Spirulina : 55-70%
    Chlorella – 55-65%

    Meat : not more than 30% usually 20% per weight

  15. Still we’re omnivorous and don’t understand all the chemicals that make us up and how they’re all used, but it’s possible to be ALIVE while also being highly nutritionally defficient as we can see from so many americans. I’m sure there are things we don’t get from just eating only plants, but it’s plausible to live nutritionally off exclusively plant. Healthy grown meat is still the densest source of protein compared to any plant, and is important if you’re a weightlifter or something like that

  16. Nothing we need is not found in plants, except B12 which comes from bacteria. Would you take a supplement, fed it to an animal and then kill it, dismember it and eat it? Or would you rather take the supplement itself?

    This study doesn’t suggest that people become vegans. It suggests that people substitute red meat and processed meats for other meats. If you do eat red meats, restrict your intake to around 300g per week. Currently average meat consumption in most Western countries (certainly in mine) is much greater than this.

    Have you even read the report? The study followed a cohort of >120,000 people over 24+ years. Yes, those who eat the most meat were also the heaviest smokers, consumed more alcohol etc. and all of these covariates were measured and controlled for.

    Of course meat can’t be the sole cause of higher mortality, neither can cigarettes. What’s your point?

  19. The fat humans store on their bodies is saturated fat.. Amazing that we would store a toxic substance like that to for potential fuel…

  20. … From a chemical engineering standpoint we’re omnivorous and you can’t change how we chemically react, so we can’t expect our bodies to just make molecules we simply need to function properly out of others. So I also strongly agree a balanced, organic diet (which includes meat) is best, but a vegan diet with HEAVY SUPPLEMENTATION is hella better than what is the norm today. The emerging problem is that we’re depleting the soil which makes our food and therefore US deficient

  21. Thanks for the antiprop. truth! Every study is flawed and we should look at it for the better correlated results such as exercise, processed food consumption, etc. We also have to observe the huge nutritional difference between something “natural” (grass fed beef) and “unnatural” (GM chickens), either way I’m sure we can agree GMO/processed should be avoided/boycotted as this is he only way to STOP IT!

  22. Stop being brainwashed by the paleo-diet gurus who sell you grass-fed beef.

  23. Source please? And doesn’t eating more fresh veggies and fruit and reducing processed foods the same as going more plant-based? You don’t sound much educated on plant-based nutrition from that comment. Veganism and plant-based eating are two different things.

  24. Dean Ornish isn’t even vegetarian, he recommend fish oil… last time I checked fish were not vegetables.
