Volume 30

Dr. Greger’s new Google Talk

I was recently honored to be invited to Google to present on How Not to Die, and they made it into an official Talk@Google! View the presentation I’ve been giving around the country on my book tour for free at bit.ly/googlegreger. It’s basically a 2016 updated version of my Uprooting the Leading Causes of Death talk.

It’s been such a pleasure and privilege to meet so many people whose lives my work has touched over the last few months touring around the country. With my speaking tour winding down (only about 50 cities left—phew!), I’m eager to catch up on all the research I’ve missed. I just completed the next nine weeks of NutritionFacts.org videos, available now in sneak preview form as part of my new DVD, in which I do a deep dive into the subject of vinegar.

Vinegar has been used as a weight-loss aid and folk remedy for diabetes for centuries, but does it actually work? Find out in my new 5-video series:

  • Does Apple Cider Vinegar Help with Weight Loss?
  • Vinegar and Artery Function
  • Can Vinegar Help with Blood Sugar Control?  
  • Optimal Vinegar Dose
  • Vinegar Mechanisms and Side Effects

*Spoiler alert*: Let’s just say I now try to sneak vinegar into all my family’s meals.

I also have new videos queued up over the next few months on wheatgrass juice, Paleo diet bone broth, and protein combining. If you don’t want to wait, all of these videos are available now as a digital download as part of my new Latest in Clinical Nutrition volume 30 (all proceeds go to charity). It can also be ordered as a physical DVD.

The current batch of videos from volume 29 are about to run out on NutritionFacts.org. So, starting next month and running until June, I’ll roll out the videos from this new DVD, volume 30. The DVDs give folks the opportunity to sneak-preview videos months ahead of time, watch them all straight through, and share them as gifts, but there is nothing on the DVDs that won’t eventually end up free online here at NutritionFacts.org. If you’d like the works—50+ hours of video—you can get the complete DVD collection.

Here’s the list of chapters from the new volume 30 DVD—a preview of what’s to come over the next few months on NutritionFacts.org:

  1. Specific Receptors for Specific Fruits and Vegetables
  2. Should Pregnant and Breastfeeding Women Take DHA?
  3. Should Vegan Women Supplement with DHA During Pregnancy?

  1. Dr. G, I assume you fly on plane a lot. Worried about exposing B12 supplements to airborne radiation, and or passing through airport scanners and detectors? Damaged, made harmful, altered? Airborne radiation accumulation of food/supplements?

      1. Thea did you by chance read Brux’s replies to me? (He mistakenly replied to me) they were beyond inappropriate. Does someone like that get blocked for good?

        1. WFPBRunner: Agreed, they were beyond inappropriate, and I’m very sorry that happened to you. I noted and appreciated that you took the grown up road in your responses. I tried to delete those messages as soon as I saw them, but another moderator had beat me to it. Brux’s replies had already been deleted by the time that I saw them. (Our new moderators rock!)

          re: “blocked for good?” There is a way to permanently blacklist someone, but we are very careful about using that option. The volunteer moderators never make that decision ourselves, but we can work with the NutritionFacts staff if we feel that someone should be blacklisted. This is not the first time that Brux has had to have posts deleted, so he knows better. I will forward this situation onto the NF staff for blacklist consideration.

          You and I both know that that outburst/breakdown had nothing to do with you in any way (even to the point of mistaking you for another poster), but again, I’m sorry that happened.

          1. They were deleted so quickly that I don’t believe anyone else in the comment section was able to read them. Either way I would suggest ignoring him in the future. I can’t even repeat what he said they were so vile. And simply because someone said meat can cause cancer?
            Thanks, Gale (AKA- Veganrunner)

            1. I’m sorry if I pushed Brux’s button and made him become nasty toward you WRPBRunner. I will try not to engage him in the future. I had to go to work and when I looked at the comments last night I saw that a bunch of his had been deleted and I hoped I had not been the cause of his tantrum but I think I was.

              1. Oh no worries. Trust me I am not sensitive to that but a nutrition forum! Yikes. A few F bombs and A bombs Etc. I guess you pushed his buttons. Too funny!

    1. Google the BBC Atkins documentary movie and discover the real scientific truth behind it. It is easy to create good sounding ‘scientific’ narratives about anything.

    2. I think he is a dangerous charlatan who needs to sell books and garner some limelight and popularity. The best science has disproven his claims time and again, and my own health experience has verified it as bogus! (There is nothing like testing a theory on yourself to really open your eyes!) People love to hear good news about their bad habits, and seems everyone I know loves their fat and fatty meats, so they believe he’s right. Sad!

    3. I am a Dr. Greger fanatic, but not vegan, so my opinion may be unusual. As such, I have been attacked on this site and disagreed with respectfully. I bet you can guess which one I prefer!
      I think that Dr. Hyman is thoughtful and open minded. I just read his book, “Eat Fat, Get Thin”. He hosted a fat summit recently and had Drs. Neal Barnard, Joel Fuhrman, and Dean Ornish on as well as several well known paleos. He was respectful to all and always started with areas of agreement. He got the best guests so he didn’t really have anybody like Atkins or the Wheat Belly doctor telling people to eat whipped cream or meat fat. He agrees with Dr. Greger that the majority of someone’s dinner plate should be vegetables. He is one of the top leaders in functional medicine, wherein lifestyle changes like Dr. Greger talks about are highlighted. He is not a patsy of BIg Pharma. He does believe that you can eat some meat and fat and be healthy. He is very specific about what kinds of meat and what kinds of fat. Like many doctors who follow nutrition, he is more focused on diabetes, inflammation and Alzheimer’s disease than heart disease, so he comes to different conclusions than Dr. Greger, but most of the conclusions, in my opinion, are in areas where there is little consensus among leading scientists and they are trying to connect the dots. Although this is my favorite nutrition site, I watch others and try to develop an overall burgeoning picture of how to apply the latest results of studies to my life.

  2. Here is an Ask the Doctor question related to the Cornell “vegetarian gene alleles” article in today’s news. The article implies that you should “eat for your type.” Isn’t it more likely (similar to how the gut adjusts iron absorption and the liver adjusts cholesterol synthesis/destruction depending on the need) that the body would adjust for the relative amounts of dietary ALA and LA vs. pre-formed EPA/DHA and AA regardless of the allele? Doesn’t the body make these things (and prostaglandins) on demand, rather than just processing what comes down the pike? Or does bio-individuality really matter in designing one’s diet?

    1. There is variability in the population so not everybody thrives on the same foods. However our bodies have been adjusting to seasonal changes and shortages of food for a long time. I advise my patients to start with a whole food plant diet with adequate Vitamin B-12 intake. Thea mentioned Dr. Greger’s February 2012 series. The Vitamin B-12 recommendations are explained in … http://nutritionfacts.org/video/cheapest-source-of-vitamin-b12/. As always if you aren’t doing well or have symptoms you should check with a qualified health care professional. You point about ALA and LA are good ones. There are some vegans who by consumption of processed products such as corn oil have an unhealthy omega-6/omega-3 ratio. However if you consume a variety of foods with minimal or no processed foods (e.g. oils are processed) you shouldn’t have to worry… trust your system to adjust as you outlined for iron. If you and your doctor decide that you should take an omega 3 supplement in form of EPA/DHA I would recommend golden algae capsules over fish oil… see http://nutritionfacts.org/video/should-we-take-epa-and-dha-omega-3-for-our-heart/. Processing does effect the levels in the body. Generally bio-individuality doesn’t matter but the proof is what works for you.

    Dear Dr. Greger,
    We are big fans, just bought your book, and have been on a plant-based diet for maybe 4 years. The story at the link just broke re a study by some Cornell folks published in Molecular Biology and Evolution, that generational plant-eaters can actually hurt their [descendents’] bodies with a fatty acid overload, particularly if their [descendents’] diet is heavy in things like meat [ok, not a problem] and sunflower oil [vegetable oil concerns me].
    The result is an increased risk of heart disease, colon cancer, and chronically high inflammation.
    So is this the first bad news about plant-based diets? Should we be worried about future generations? Thanks! (We love your daily messages btw.)

    1. Hi Rick,

      Great questions! If you haven’t had a chance to look at the study itself, you can find it here:

      Molecular Biology and Evolution Article

      It’s heavy on scientific jargon, but very interesting!!

      This has been getting a lot of press lately, so I think it’s worth a bit of a deep dive to see what is really going on!

      The study focuses on genes that allow the body to make long chain polyunsaturated fatty acids (LCPUFAs). As background, LCPUFAs can be divided into n-6 and n-3 fatty acids (also referred to as omega-6 and omega-3 fatty acids, respectively) which you’ve probably heard of.

      Arachidonic acid (AA) is an omega-6 fatty acid and docosahexaenoic acid (DHA) is an omega-3 fatty acid. Arachidonic Acid (AA) comes from the essential fatty acid, linoleic acid and DHA is made from the essential fatty acid alpha-linolenic acid . Both linoleic acid and alpha-linolenic acid come from our diet.

      In addition to our body making AA and DHA though we can get these fatty acids from our diet directly with AA coming mostly from meat sources and DHA mostly from oily fish such as herring, tuna, and salmon. In general, as you probably know, arachidonic acid (omega-6) is very pro-inflammatory and NOT very good for you while DHA is anti-inflammatory and important for your health in several ways. Omega 3 and Omega 6

      But what about the study?? Well, most of the conclusions of the study are below, and here is how I would interpret them. They found that diet, over many, many generations, MAY have resulted in a higher frequency of a mutation called rs66698963. I should be clear that the study does not prove this in any way, it just shows a higher rate of this gene variant in populations known to have different diets. This mutation is an insertion or deletion of a sequence of DNA that regulates the expression of two genes, FADS1 and FADS2. These genes are key to making long chain polyunsaturated fats, both AA and DHA.

      The insertion mutation (I) is possibly increased in populations who have primarily vegetarian diets. Interestingly, the deletion mutation of the same sequence (D) may be found more in populations which have more access to fatty fish, such as the Greenlandic Inuit.

      In people with the I/I genotype (an insertion gene from both parents), they have more expression of the enzyme FDAS-1 and have an increased ability to make long chain fatty acids (both omega-3 and omega-6). People with the D/D genotype (a deletion from both parents) have less expression of this enzyme and a decreased ability to produce long chain fatty acids (but not NO ability, just LESS ability to do so). So far so good?

      OK, so what does this really mean? They conclude that in I/I people who are vegan or vegetarian “LCPUFA would depend on the relative proportions of linoleic acid and alpha-linoleic acid”. In other words, if you have the I/I genotype, and you don’t eat meat, you will end up with more AA if you eat more linoleic acid and you will end up with more DEA if you eat more alpha-linoleic acid.

      The key though, in my opinion is this “in a food system dominated by linoleic acid”. That is OUR food system on the standard American diet. We gobble linoleic acid from corn sunflower, soybean, cottonseed and other common vegetable oils, all things that Dr. Gregor already recommends that you avoid. It’s probably not a shock that eating a lot of oil is not good for you! The study concludes with what I think is a very reasonable recommendation for “balanced consumption of precursors” meaning don’t spend your time gobbling corn oil! ☺

      They go on to state that if you know you are an I/I genotype AND you decide to eat a lot of linoleic acid (vegetable oil) then you should probably eat some EPA and DHA directly to balance it out, “I/I carriers consuming excess 18:2n-6 may particularly benefit from consumption of EPA and DHA.” Again, totally reasonable and just what the good Dr. Gregor recommends anyway! Nutrition Recommendations>

      Study Conclusions

      Collectively our data suggest that FADS2 indel genotypes contribute to individual variability in response to PUFA consumption. In the vegan or vegetarian scenario in which only, or primarily, precursors would be consumed, tissue LCPUFA would depend on the relative proportions of 18:2n-6 (linoleic acid) and 18:3n-3 (alpha –linoleic acid). In a food system dominated by linoleic acid, I/I genotype carriers would maintain higher basal arachidonic acid and presumably greater inflammatory potential and attendant higher rates of chronic disease related to inflammation. Balanced consumption of precursors would be particularly important for I/I genotype carriers. I/I carriers consuming excess 18:2n-6 may particularly benefit from consumption of EPA and DHA which bypass the desaturation steps, as a direct balance to ARA.

      1. Hi, this is a great response. Although I am not in the medical field, I have followed developments in the field of nutrition generally for years and (naturally :) I am big fan of Dr. G and this site. My husband sent me the link when he noticed the article and after reading through, I determined that really the bottom line here is (as we have been adivised by Dr. G and others) to steer clear of “linoleic acid from corn, sunflower, soybean, cottonseed and other common vegetable oils.” Although we do use some small amount of oil in our diet, we avoid these. Also, I found it interesting that various news reporting sources selected different aspects of the report as their main focus.

        1. Hi Pam,

          I couldn’t agree more! I think the article is fascinating in terms of offering us potential mechanisms as to why some folks may be extra vulnerable to a Western diet. It’s interesting to me though that this article is getting so much press and, as you mentioned, so much focus on different aspects of their findings. It really just re-iterates what we have known for a long time: vegetable oil is no good for you!

          Also, even in their US population sample 57% of the population carried at least one “I” gene, the one that increases expression of the enzyme responsible for synthesis of long chain fatty acids and the one that may make people vulnerable to a diet high in omega-6 fatty acids.

          I obviously don’t know my own genetics but based on their data there’s a decent chance I carry at least one copy of the “I” gene, so no corn oil for me!! ☺

  4. Dr. Greger I’m recommending you file a complaint with Wikipedia for your biography it contains contentious material about you that is poorly sourced and the editors keep putting it back in when I try to remove it from the article. It is potentially libellous Also see the section Harriet A. Hall in the talk pages. Thank you, Tim Picerilo.

  5. Hi, I was just wondering about the health concerns of self-induced vomiting (I am bulimic), I am trying to recover from it, and I think knowing exactly how this disease harms the body would be of good help going into therapy

  6. Dr. Greger, I am reading HOW NOT TO DIE. I love it. I found this in “2016 Yellowstone Spring.,” published by the Natnal Park Service: “Do not feed any wild animals, including birds. Consuming human food is unhealthy and encourages aggressive behaviour that may require management action…” At least someone gets it!

  7. Dr Gregor, question for you ! A while ago you made a video about vitamin e tocopherol but recent studies show that vitamin e tocotrienols have been used to prevent and cure major degenerative diseases yet it seems like nobody knows about this special type of vitamin that could save a lot of peoples lives. can you make a video on this ?

  8. Just watched the talk Dr Greger gave at Google and thought it was fantastic. Especially the comparsion between smoking. In the comparsion with smoking, Dr Greger said there was approx 7,000 studies about the harms of smoking before the medical community really started to take it seriously. I wondered approx how many studies there currently are showing the harm in eating animal products?

  9. 16 years after colon cancer surgery i suffer with bowel issues. what can i add to my plant based diet to help normalize my bowel issues?

    1. Elise North: When all is said and done, Hyman is citing studies, but he is misleading people in various ways when he does it. VegCoach found the following 4 minute video about one of Mark Hyman’s claims that demonstrates my point. https://www.youtube.com/watch?v=RovJRlTbsgw&feature=youtu.be
      Also, the following post from Tom Goff looks into some of the other of Hyman’s claims. http://nutritionfacts.org/2016/03/22/the-effects-of-dietary-cholesterol-on-blood-cholesterol/#comment-2584872026
      I agree that it *is* terribly confusing for most people. It really frustrates me that a lack of integrity and basic human decency is affecting the very lives of so many people.
