Doctor's Note

Not that there aren’t randomized controlled studies showing the extraordinary power of plant-based diets to prevent, treat, and even reverse disease, not the least of which is Dr. Ornish’s landmark Lifestyle Heart Trial, which is what did it for me 25 years ago.  That’s the one I started my annual talk last year with: From Table to Able: Combating Disabling Diseases with Food.

If you liked this video, you’ll really like this one: Evidence-Based Medicine or Evidence-Biased?

Here’s the video in which I review the evidence surrounding treating multiple sclerosis with nutrition: Treating Multiple Sclerosis with the Swank MS Diet.

There are more parallels one can draw between the Big Tobacco and Big Food. See Big Food Using the Tobacco Industry Playbook and at least the final 20 minutes of Food as Medicine.

    it will be good put to the test the population that is following WFPB maybe you find a lot of us at NF :) even if not double blind fashion i wonder how many disease are in between us compare to average diets and deficient vegetarian and vegan diets, paleo,etc.. normally in the studies are compared super bad diets with quite bad diets haha. so it will be interesting to proof the effectiveness of it.

  • Noe Marcial

    I wonder why it is no more replicas of these amazing studies, or the reversing of a cardiovascular disease with diet, this one of sclerosis multiple, etc.. it is like in 30 years nobody did again?if somebody does that It will show with more strength the facts to some researchers..

    about MS do you know something about the TH1 TH2 balance, th17 and Tregs cells? seems an amazing area of research of the autoimmune diseases and are critical influence by what we eat. I don’t know but may be that saturated fats lead to leaky gut and a leaky gut create a Huge disorder in the T Helper cells being them the one that do the final attack. and some plants together with vitamin D and fatty acids seems to help. but depending in the type of disorder some substances momentaneously have a negative effect over stimulating th1 or th2. i will love to hear what do you think about that.
    thank you!!

    • Rebecca Cody

      Dr McDougall’s diet is very similar to Dr Swank’s and he has stories from many who successfully halted their MS. http://www.dr,,

    • Matthew Smith

      A large dose of Vitamin D3, 12,000 IU, taken daily, seems to really treat MS, even cure it. I personally believe, in my opinion only, that if you need to have your thyroid levels tested, then you need to take Iodine. The consequences of taking Iodine can be a weak pulse or even not being able to feel your heartbeat. Iodine treats pain. I am 34 year old non smoker who loves the pleasant side effects of Iodine supplementation.

    A little off topic. Dr. Greger has been doing interviews about the book. On iTunes, you can put in “Michael Greger” and find several podcast interviews, already. Of the ones that I have listened to, I thought the one on the Leonard Lopate show (which was also broadcast on WNYC radio) was GREAT – a lot of info in a reasonable amount of time. Here is the info:

    Leonard Lopate Show – 33min, and EXCELLENT!, Dec 18
    – iTunes Link
    or, find it this way:
    – WNYC link – to listen there or via some other Podcast mechanism, via the links on that webpage.

    In addition, Dr. Greger did a short video interview on the Faux Noise Channel – 3.5min, Dec 19, “Foods that Can Save Your Life” A good interview but short.
    – Link to the video

    C’mon Dr. G. I just read the entire parachute study and it’s hilarious. You could’ve cited more of it :)
    “A call to (broken) arms”

    “Contributors: GCSS had the original idea. JPP tried to talk him out of
    it. JPP did the first literature search but GCSS lost it. GCSS drafted
    the manuscript but JPP deleted all the best jokes. GCSS is the
    guarantor, and JPP says it serves him right.”

    We need more of this!

  • Micki Jacobs

    Actually, the data support nutrient repletion and vitamin K is a nutrient from which many suffer subclinical insufficiency.
    So Ornish and others used lots and lots of veggies, which happen to be high in vitamin K1, and which therefore overcome their patients’ subclincial insufficiency and thus make for health improvement. More K is better K!
    Other ways to be sufficient include more vitamin K2, which is what we should be investigating.
    Vitamin K2 can be made endogenously in tissues throughout the body from all forms of dietary vitamin K, it can be consumed, and a very small amount can be absorbed from the K2 made by gut bacteria.
    There is strong evidence that the cultures with the most autonomous longevity consume vitamin K2. It can be from fermented foods (both plant and animal), from offal, from organ meats, from mollusks or insects, or simply animal fats.
    We have asked the wrong things about dietary fats – what their bonds are, whether they are saturated/polyunsaturated/monosaturated – and we could more accurately ask what the fat does to vitamin K and vitamin K actions, instead, and get the same results. Namely, that soy and canola (if not hydrogenated) as well as olive oil are highly bioavailable K1 and therefore offer benefits; that so-called ‘high saturated fats foods’ (which is code for animal fats and is incredibly inaccurate because, for example, lard is extremely high in monosaturated fats); and that so-called ‘monosaturated fat foods’ are more about the K content.
    Trans fatty acids are really biomarkers of dihydrophylloquinone, an aberrant form of vitamin K that inhibits MK-4 biosynthesis and also activation of vitamin K-dependent proteins beyond the coagulation cascade; so trans fats DO lead to bad things, but not from the mechanisms you describe.
    The mechanisms of vitamin K2 are also impaired by some statins and some bisphosphonates, which inhibit MK-4 biosynthesis and increase risk of the many diseases now recognized to be associated (and some evidence of CAUSALITY) with poor vitamin K status such as diabetes, fractures, cardiovascular disease, AD, cancer, and more.
    A totally plant based diet MIGHT meet vitamin K needs if very high in K1 (BTW, we can only absorb in the single digit percentages from leafy greens and other veggies, but the oils are much more bioavailable), but if one FERMENTS some of the foods (e.g. natto, sauerkraut, etc), it is soooo much better because that offers some K2.
    This discussion is ignoring data that doesn’t support it, but I have no doubt that Ornish could dramatically improve the health of those who would listen. Only there are other ways that are equally effective and it comes down to (in many, many cases) vitamin K status. And animal foods are wonderful! And healthy. Just not as the USDA is allowing them to be raised. Sad. The USDA has allowed all sorts of bad things, but don’t throw out the baby with the bathwater…just know that the RIGHT way to raise animals makes for good foods.

    Go ahead…search: vitamin K2, menaquinones, UBIAD1, osteocalcin, matrix gla protein, Gprc6a, calcium homeostasis!!!

    • MrMcadamry .

      Is there more vitamin K if they are afraid or calm.

      What do you feed them for their last meal for the most vitamin K.

      If you skin them before slitting their throats does that take away any of the vitamin K?

      I hear slaughter can be bloody do you have to catch the blood in something or just let it get everywhere.

      Someone told me there is lots of vitamin K in the fresh blood and if you drink the blood fresh you get an uber super K boost straight to your cells.

      The blood has to be real fresh though like the cow or whatever has to still be alive, looking at you, when you cut it’s throat and drink it’s blood for the vitamin K boost.

      Oh but the animal has to be grass fed and specially treated before the day you decide it’s time for it to die for the sake of vitamin K.

      Cuz I hear if you raise them juuuuust right, all the hormones saturated fats and cholesterol aren’t included in the meat.

      And the animals just walk right up to you with big smiles, drop the knife at your feet and lay belly up with their throats out.

      And their friends and family just gather around peacefully to smile and watch.

      No screams and no fear at all.

      I bet that would be such a good K boost.

      • Marie Gilman

        You are a total sadist and should be ashamed of all your comments.

    • Matthew Smith

      Hello! I love the idea of Vitamin B12, Selenium, Potassium, Silicon and Vitamin K2 Supplementation for longevity. I have read the book “Vitamin K2 and the Calcium Paradox.” There is nothing these powerful vitamins won’t do. These are vitamins that are very rare in the Human diet, but are so essential their rarity has lead to much bewilderment among doctors. Just take braces. Misaligned teeth can be a sign of a vitamin K2 deficiency. There is some evidence that every disease, with a few exceptions, has a vitamin D3 deficiency at its roots.

    • Tom Goff

      Everything is a magic bullet at one time or other it seems. Whether it is vitamin C, vitamin B12, potassium, vitamin D vitamin E or, this year, vitamin K2. However, we don’t eat vitamins or minerals we eat food. And foods usually contain a mix of health promoting and health impairing elements. Claiming animal foods are “wonderful” is simply naive because they contain so many health-impairing elements which mean that there are no net health benefits from eating them, no matter how much B12 or K2 they may contain.
      This is best demonstrated by the results of the 7th Day Adventist studies which show clear mortality and other health benefits accruing to people on vegetarian and vegan diets compared to people eating meat, despite their presumably low B12 and vitamin K2 consumption.
      You could, I suppose, make a case for some fish consumption because in those 7th Day Adventist studies “pesco-vegetarians” had the lowest mortality risk. However, I prefer to get my B12 from supplements and my omega 3s and vitamin K2 from vegetarian sources where possible (although I own to taking a D3/K2 supplement in addition to supplemental B12).

      • Alan

        Right on. I am a 7th Day Adventist and have been for about 23 yrs. And always looking for the best diet. I have gotten more help from Dr McDougall and his starch based diet that anywhere.. No Animal !! And 95% WFPB. I use a very small amount of boxed cereal with no added sugar. Only a small amount at a time. At 60 i feel better that i have in my whole life. I work hard almost everyday except on the Seventh Day Sabbath. Most of the work is in the garden and cutting and hauling fire wood. The gardening is year round, as i have 2 unheated green houses and can grow certain foods in them all year round. And i use organic methods in my garden and eat a very large percentage of my food from our garden. Especially the veggies. Also the working out doors in nature and with natures God is very healing to the body, mind and soul !!!

        • Tom Goff

          Thanks Alan. I am an atheist and I love my tea but you seem to have a wonderfully healthy lifestyle. More power to your elbow.

      • Alan

        I would like to add that eating meat is only eating second hand vegetables that the animals ate. Let us be wise and eliminate the middle man or in this case middle animal !!!!

    • guest

      “And animal foods are wonderful! And healthy” –

      No they are not. That is not what the best available data show. Animal foods are terrible for your health. Not just the toxic heme iron and endotoxins but the natural Trans fat and saturated fat as well and the list goes on. The best available evidence shows that animal foods are toxic to the human body and should be avoid. You can get all the Vit K you need in plant foods and avoid the toxic affect and diseases directly caused by animal based products.

    • HemoDynamic, MD – NF Volunteer

      I will outright say that you are completely off base regarding your comment, “And animal foods are wonderful! And healthy.”

      Nothing could be further from the truth! Health of a human has nothing to do how animals are raised and eaten, health of a human has everything to do with our lifestyle!

      And that is:
      #1. Don’t smoke or do drugs including alcohol [I know the ETOH (ETOH=Ethyl alcohol) one hurts for a lot of us]
      #2. Eat a low fat, varied, whole food plant based diet. (Yes that means no animal foods of any kind)
      #3. Get daily exercise–at least one hour a day, and preferably 90 minutes per day.
      #4. Get 7-9 hours of sleep per day.
      #5. Drink plenty of water and/or tea daily.
      #6. Try to keep stress low in your life. This requires mindfulness, presence, being in The Now.

      And as to whether animals are healthy for us to eat or not, the sheer preponderance of evidence shows beyond any reasonable doubt that eating animals creates an overwhelming burden of inflammation and toxins (eg. heterocyclic amines–especially PhiP) and slams our bodies with cholesterol, saturated fat, both which have been shown to be the problem with our number one killer in the US and that is cardiovascular disease.

      In the words of a great teacher of mine:
      Identify what you know,
      What you don’t know,
      And what you believe,
      And don’t confuse the three!

      I would encourage you to review all the videos and blogs on this unbiased (as best as is possible) website and review all the sources cited and then revisit your comment. I would find it very hard to believe that with an open mind you would come to the same conclusion.

  • Lawrence

    In my sixty years of being alive, I have never known hunger. And, neither have I known anyone who has. Looking
    back on how much I have learned by following Dr. Greger’s unparalleled efforts to inform anyone and everyone
    who will listen as to what to eat to optimize health and longevity, I am amazed at my initial ignorance on this
    subject. Happily, among my many appetites is the hunger for knowledge and understanding, in particular the
    history of the twentieth century into which I was born. And on this subject, I continue to be amazed at my ignorance.

    On November 7, 2015 in Washington, D.C. a new monument was dedicated in remembrance of what is known as ‘The
    Holodomor,’ a Ukraine word meaning “Hunger Extermination.” This was a period in East European/Soviet history around 1929-
    33 when Joseph Stalin ravaged the population of the Ukraine through forced exile, enslavement and starvation to
    expropriate the agricultural bounty of this vast region to be sold on the world market for hard currency used
    to industrialize the nascent Soviet Union (USSR). What was this bounty you ask? Wheat. For the nearly ten
    million people who were systematically starved to death, what was denied to them and what would have kept them
    alive was whole grain wheat. In fact, the memorial that was dedicated in Washington, D.C. is a stone wall of
    wheat. Please, search on this and see it for yourselves. What amazes me is how ignorant I was about not
    only The Holodomor, but also of this event.

    Now, there are many people who post comments on this website professing the evils of whole grains,
    especially wheat. Entire books are now in circulation about the evils of wheat. But, for millions of people
    then and billions of people now, the difference between life and death from starvation is the abundance of
    wheat and other whole grains. So, the next time you hear someone disparaging whole grains in general
    and whole grain wheat in particular, remember The Holodomor and simply move on.

    • HaltheVegan

      Yes, the farming of wheat seems to have kept many hungry people from starving in the past couple of hundred years. And, I, too, have often wondered why this massacre by Stalin has never been publicized as have similar atrocities by other dictators of the same era. I never heard of this event in history classes in school, nor college, nor even the History channel when growing up. I only became aware of it when the Internet became available and articles started appearing on different history oriented websites. The Internet has become such a valuable resource to a free society, as readers of the website can all attest to.

    • Alan

      Right on – I eat plenty of whole grains and have lots of energy and i am very healthy at 60 !!!

    • Ray Tajoma

      I love WHEAT & GLUTEN. I think the reason Gluten (wheat protein) has got a bad reputation is because it is a vegan alternative to meat that has no saturated fat and no cholesterol and triple the “PROTEIN” – the #1 reason most people eat meat. This scientific fact is detrimental to meat industry and they spend billions disparaging gluten (a cheap superior alternative to meat).

  • Herb

    I’d like to see Dr Greger discuss the Wahls protocol. Dr Wahls reversed her MS by going on a modified Paleo diet with grass fed beef, organ meats and copious amounts (9 cups!) of sulfur rich and colorful vegetables and fruits. Wheat is prohibited as is dairy. See

    There is a trial of her diet ongoing now. It may well be that some MS patients thrive on an extreme low fat diet – others on a high fat meat and vegetable based diet.

    • Joseph Gonzales R.D.

      Cool thanks for sharing. Do you know if Dr. Wahls has published any of this data or is there only a book written about the doctor’s experience? I’d be curious to see if there is any literature.

    • Julie

      Even after going gluten and dairy free, Dr. Wahls did not see much improvement in her MS until she implemented large quantities of colorful vegetables into her diet. Although she recommends some organ meat, I don’t get the impression that the overall diet is very high in saturated fat.

    • Rebecca Cody

      Herb, I agree. I think it’s easy to overlook the fact that, while we have much in common, we are all biological individuals as well. I once visited a paleo website and the subject of MS was up. I commented about the Swank diet and the MS patients who have told their success stories on Dr McDougall’s site. A woman wrote back whose MS had progressed dramatically on that diet. It had put her into a wheelchair. Then she tried the Wahls diet and regained most of her bodily functioning, was out of the wheelchair and doing all normal activities.

      We all have genetic differences that affect us. Many people consume aspartame daily without obvious consequence, while putting it into coffee two mornings in a row caused me to have a seizure. This is likely the result of the MTHFR snp. Our genetic variables are endless!

  • Joel Kahn

          Hey, Welcome, Dr.Kahn, I read about your new restaurant in Detroit! Congratulations! A cardiologist opening a vegan restaurant, that’s very cool. Once at a fancy French restaurant, the chef came out to our table when we were served, and told us how each dish was prepared, it was very impressive. I can imagine you, as Maitre D, lab coat and stethoscope, recommending various dishes, explaning the health benefits of the meal.

    • MikeOnRaw


    • GEBrand

      Dr. Kahn – I just went to your Facebook page and joined your fight against the atrocious food that hospitals serve. I just spent 2 years in and out of my local hospital – Swedish Medical Center, Englewood CO – with my seriously ill Mother (lung cancer) and the only thing they offered health conscious eaters was the salad bar. You should have seen the atrocious slop that they peddled. I have coined a new term for this slop and I call it Nutricrap. I don’t think I need to explain it.
      I also decided to call out my own local hospital by name – Swedish Medical Center, Englewood, CO. Our taxes support our hospitals (via Medicare and other avenues) and the public should be outraged that hospitals serve Nutricrap while claiming to care about the health of the patients. This is, in fact, not a health care system but a disease care system and our medical care system is disfunctionally addicted to the money the taxpayers pay for this less than stellar service that is both inadequate and sometimes dangerous. Serving Nutricrap sabotages our health while they take our money. Does that not make anyone else as angry as it makes me?
      I would like to encourage readers here to join your Facebook fight and to publicly call out their own local hospital that sabotages everyone’s health that eats there.
      Hospitals should be a stanchion of good habits, set the standard, and exhibit excellence, not be a perpetrator of the pathetic status quo of disease causation.
      I applaud Dr. Kahn for standing up. I encourage everyone reading here to exhibit publicly their outrage and publicly call out their neighborhood hospital on Dr. Kahn’s facebook page. Enough is enough.

      • Joel Kahn MD

    • HemoDynamic, MD – NF Volunteer

      Yes and even though there weren’t any significant improvement on the MRI results, which we were hoping, the patients in the diet group all enjoyed significant improvement in their ADL’s (Activities of Daily Living) which I feel is the most important result! The patients got better! “Our Diet & Multiple Sclerosis Study showed immediate and permanent positive changes in feelings of “well being” of patients with MS. Benefits for fatigue measurements were observed within a month of beginning the intervention diet and were sustained at the same improved level throughout the year.”
      No other treatment for MS, other than plant based eating, has ever shown such amazing results!

      Plant based eating is the most powerful medicine known to man, and your body the most amazing healing machine!

  • robert

    Not related to todays discussion, but I see that another paper from the PREDIMED study,, is being touted in the press: “Diet heavy on olive oil cuts breast cancer risk by 62%, study says” – headline in the LATimes. Dr. Greger previously reviewed a paper from the PREDIMED: and it would be interesting to hear his analysis on this paper.

    • Joseph Gonzales R.D.

      Dr. Greger says that it’s important to account for all of the evidence, not just one paper. This video on olive oil mentions some of the research from the PREDIMED study, as well. Newspaper headlines sure like to make a splash for attention.

    • Matthew Smith

      The Bible itself, Revelations, says “and do not damage the oil and the wine!” Revelations 6.6 I am so surprised that Dr. Greger does not approve of those things. Salt and Pomegranates are also mentioned. These are presumably very healthy, but not recognized here. Culturally, they are very valuable.

      • Alan

        Hi Mathew – The book of Revelation is a book of symbols! Usually the oil meaning the Holy Spirit and wine speaking of Bible doctrines. If you want to know what the Lord thinks about wine i suggest you read Proverbs 20:1, 23:29-35, 31:4-7. Also keep in mind that a lot of times in the Bible when wine is mentioned it is speaking of unfermented grape juice. Proverbs 23:29-35 is plainly speaking about fermented grape juice or wine and it plainly tells the woes of using it.

        • Matthew Smith

          I disagree. I think the author of Revelations presents a stark version of life the way it is. It seems to clearly mean a victory, not a symbolic one. I am sure the Book says to spare olive oil and wine. Without these, there seems to be very little to eat. If I do not read Revelations literally, I lose the meaning of the Bible in my life.

  • Michael

    That parachute clip was a great find, love it!

  • johnas

    Randomized, controlled trials are the gold standard, but they’re not perfect, when the test subjects are humans not genetically identical mice living in cages eating identical diets. Randomized controlled trials involving humans and examining the same theory could lead to different results, which could result in cherry picking when the studies are reported to the general public. Meta analysis is an attempt to deal with this problem, but meta analysis is based on statistics and as we all know numbers can be manipulated to tell anything.

    • Tom Goff

      Even when the test subjects are genetically identical mice living cages eating identical diets, results can vary. For example:

      “C57BL/6J mice were fed with a HF diet (60% kcal/fat) or control diets (15% kcal/fat) for 27 months. One-half of the mice on the HF diet developed obesity (diet-induced obese (DIO) mice), whereas the remaining mice were diet resistant (DR). At 8 months of age, both DIO and DR groups had increased hyperglycemic response during a glucose tolerance test, which was normalized in 16-month-old mice. At this latter time point, all groups presented similar performance in cognitive tests (Morris water maze and inhibitory avoidance). The survival curves of the HF and control diet groups started to diverge at 15 months of age and, after 27 months, the survival rate of mice in the DIO and DR groups was 40%, whereas in the control diet group it was 75%.”
      Source:”High saturated fat and low carbohydrate diet decreases lifespan independent of body weight in mice”

      How much more (individual) variability is there likely to be among free-living humans? Perhaps some of those anecdotal reports of people on HFLC diets staying slim really are true ….. although many of the successful ones also appear to be ferocious exercisers. And note that while most of the high fat diet mice had died by 27 months of age, 40% were still alive. Survivorship bias

  • MikeOnRaw

    It can be so silly how people simply freak out when a dietary lifestyle change shows benefits, but because each lifestyle change isn’t broken down and tested separately. Such people will disregard all dietary lifestyle changes because no single change can be pointed out. It’s like they forget that our body is a system of functions “working together”.

    Why Is So Much Reported Science Wrong (

    An article from Berkeley’s California Magazine explains some of the reasons science reporting is often at odds with actual science. Quoting: “Where journalism favors neat story arcs, science progresses jerkily, with false starts and misdirections in a long, uneven path to the truth—or at least to scientific consensus. The types of stories that reporters choose to pursue can also be a problem, says Peter Aldhous, [lecturer and reporter]. ‘As journalists, we tend to gravitate to the counterintuitive, the surprising, the man-bites-dog story,’ he explains. ‘In science, that can lead us into highlighting stuff that’s less likely to be correct.’ If a finding is surprising or anomalous, in other words, there’s a good chance that it’s wrong.

    On the flip side, when good findings do get published, they’re often not as earth shattering as a writer might hope. … So journalists and their editors might spice up a study’s findings a bit, stick the caveats at the end, and write an eye-catching, snappy headline—not necessarily with the intent to mislead, but making it that much more likely for readers to misinterpret the results.” The article also makes suggestions for both journalists and the scientific community to keep science reporting interesting while being more accurate.

    • basehitz

      Follow the money. I find a high correlation between what gets reported and influence from monetary interests. For example, investigative journalists found evidence that drug companies were pushing vaccines onto the market with unacceptable risks which they knew about BEFORE it became publicly available. The journalists reported (through other venues) that top management of that news network spiked the story and wouldn’t give a credible answer why. I think it’s obvious. Think of all the advertising revenue giant drug companies pay. They only need to threaten pulling their ads and management folds. Unfortunately today it seems everyone has to be vetted before they can be trusted. But when they are identified, it is a very valuable source. Dr G is in that small camp IMO.

  • shirleycolee

    Ivy Larsen and her husband Andy Larsen a bariatric surgeon have written books, including Clean Cuisine. Ivy has put her MS in remission largely through her diet regime.

  • Matthew Smith

    Vitamin D3, which Dr. Greger recommends or has recommended highly, can treat MS very quickly. A large but necessary dose for MS would be 12,000 IU a day as recommend by the late Dr. Hoffer for at least two patents.

    Here’s a documentary on Cannabis research. Give it a few minutes even if you have no interest in treating yourself or others in your care. It’s the safest medicine out there.

    • Lawrence

      Yes, learn. And then VOTE! A vote for cannabis is a vote for true personal freedom, not the phony ‘personal freedom’ based on political ideologies that serve the interests of the few at the expense of the many. Momentum to end cannabis prohibition is building:

    It is so wonderful. After I eat I simply add to the food dairy index giving me an ongoing percentage of how I am doing for the day. When I am away from home I use the App as a resource of what to eat. The App automatically resets itself for the next day! Awesome!
    Dr. Greger you have made eating healthy soooooo much easier. Lol, I shared the App with a panel of people looking to improve their health today at a 2016 planning mtg. Now everyone in the group is using your App.
    Life is Good…

  • Hi, I have just started reading How Not to Die and I think it is a great book, HOWEVER when I looked into the China Study, I found some people debating its validity. The website below talks about a list of things that may even contradict Dr. Geger’s statements. Can someone please look into this article and get me to trust a plant food diet? Thanks

      Sebastyan: It’s a fair question. You can find a few other websites also claiming to have debunked the China Study and/or the whole idea of a plant based diet. Those articles are a mix of various fallacies and outright lies. It can be hard for someone who is not familiar with the science to figure it out.
      Others may be able to do more than I, but for myself, I feel that countering sites like Weston Price is not something that can be done well in post like this one. Instead, I will refer you to a website that has done a phenomenal job of explaining exactly what is wrong with the arguments on the Weston Price site a well as other similar sites. is a volunteer work by a man who got fed up with the lies. He has the skills to put together a really well done scholarly work, complete with references. (You have to pause the video and write down the information, but PlantPositive gives you enough information to find the study he is quoting or discussing if you want to.) He did this work in video fashion using language that I generally find quite fun. So, I would encourage you to spend some time reviewing some of the videos on PlantPostiive’s site. I did a search on the site for ‘Weston’ and got the following page. But you can look at the table of contents on the right of the screen and pick a series and start watching that way too.
      Hope this helps.

    I am just so confused. Every time I think I understand which diet is the best for overall health, another health expert shows an opposite point of view with research and science to back it up. Right now there is a fat summit going. Can Dr. Gregor please check this out, along with their research, and comment. It’s so hard to know what to do with everyone giving you different research to a different approach to health.
    Thank you.

      In this small study by Dr. Meyer Friedman half a century ago, blood sludging was found to occur in people with stressful occupations, 4 hours after eating a breakfast with approx. 140grams of fat.
      Dr. Swank’s hypothesis was that this sludging causes some kind of small infarcts that damage the blood-brain barrier and expose the nerve cells to toxins in the blood, causing MS.
      I find it incredibly hard to believe and understand why no further research is done on this blood sludging. These results seem to imply that practically anyone following a low carb diet (especially if they have a stressful job) could be walking around with tiny infarcts happening inside their brains and other tissues all of the time. More on this and a great video showing blood sludging in hamsters at 36min in the video can be found here:

    Great Britain’s Most Outspoken Cardiologist Sets the Record Straight on Saturated Fats
    June 05, 2016

    “For optimal health, seek to get 75 to 85 percent of your total calories as healthy fat, primarily monosaturated and saturated. Limit PUFAs to 10 percent and omega-6 fats to 5 percent”

    I wish there could be a friendly debate between Dr. Mercola and Dr. Greger where they could discuss the evidence and why it is that they end up taking the approaches they do.

    Garden of Eden…Genesis 1:30… initially plant-based! …Daniel, when he asked to not eat the king’s rich foods, instead asked to eat pulses…”The original word for pulse is zeroa, which according to the Enhanced Strongs Lexicon is literally translated, vegetables. Pulse in this context has typically been said to mean, lentils, chickpeas or some sort of legume or seed type food.” So…intelligently designed (my opinion)
    Went 99% “Plant-Strong” 6 months ago. (fresh rainbow trout maybe once a week -Jesus ate fish, but not the drug-laden, antibiotic riddled ones)
    As an airline pilot, I have to get a flight physical every 6 months. At age 50 on my last one, Blood Pressure 100/70, on my EKG the heart bump I’ve had all my flying life- GONE (Doc said that was from inflammation and asked if I had changed anything.) Cholesterol 130…visceral fat I’ve never been able to lose-GONE!
    Healthiest I’ve EVER BEEN,
    I know there is a 1 out of 1 chance of dying, but as a Christian, we are encouraged to seek wisdom. Once I read HNTD, I couldn’t “unknow” what I had learned, so I had to start making “informed” choices.
    Thanks Dr G. I borrowed your book from my local library on the iPad I use to fly because I thought, what a strange title, “How Not to Die.” Ended up buying it on Kindle and reread it often…
