    Thank you for this and the other videos! A Convergence of Evidence, yes. Like the index and all of it. Very nice.

    • Michael Greger M.D.

      Isn’t the index great? I couldn’t be happier with how the site turned out.

  • dilip

    Dr. Greger, thanks for launching such an invaluable resource! Yay! –Dilip

    • Michael Greger M.D.

      I’m glad you found it useful–please help me spread the word.

  • Eric Needs

    And what’s even more amazing is how no one know this… Spread the word!

  • Michael Greger M.D.

    The food and beverage industry spends billions of dollars every year marketing junk to us, to our children, contributing to the public’s confusion about basic, accepted nutrition principles. I’m glad to be one little voice trying to push out some science!

  • yummy

    Is Co-Q-10 necessary for heart health…if so, is ubiquinol so much better than ubiquinone? Or, is this just a lot of hype and another waste of money?

  • Dr Greger: I had artery bypass surgery in 1997 and have a prescription for 40 mg. of lipitor to lower my cholesterol. Three months ago I went to a vegan no oil diet, and even though I cut the lipitor dose in half, I was pleased to learn that my cholesterol measured a mere 97. My LDL reading was also only 50 but my concern is that my HDL level was only a very low 27. Should I be concerned?

    • DrDons

      Congratulations on improving your diet and reducing your medication. You have made great strides in minimizing the chance of recurrent problems. I would not worry about the low HDL. HDL goes down with the other cholesterols when you adopt an improved diet… partly due to the reduction in a transport molecule in your blood so free HDL is not as low as you might assume. The levels of LDL and total cholesterol you report should allow you to further reduce or eliminate your statin. You need to continue to work with your physician(s). I would suggest reading Dr. Caldwell Esselstyn’s book on Preventing and Reversing Heart Disease… he also has a new DVD out but I haven’t had a chance to view it yet. I would also suggest you read Dr. McDougalls newletter article on Statins, and keep tuned to nutrtionfacts as the science and recommendations keep changing. Good luck.

  • wickedchicken

    Incredible info. It’s such a shame that this info is NOT given attention from the media. One would think newspapers and media would be ALL OVER it. Ground-breaking news that is too practical to make the cut???

    The thing is, vegetarian diets for lipid lowering advice… It’s not first line advice, as of yet anyway, and to suggest it as a healthcare professional, one can be seen as promoting their own lifestyle without sufficient guidelines to back you up. So, when will this get enough regognition to be used as a first-line Rx????

    • Jackie Thomas

      Never, I’m afraid. There’s no $ in it. Can you imagine what a big decrease in bypasses, other heart surgery would do to the profession? There´s no lobby for kale or broccoli, sadly

    • HealthyStart2Day

      As this very article states, as much as $20 billion dollars could be saved with proper diet and nutrition. Prior to 2015 I had only been to see a doctor twice in 15 years; once for shingles and the other for a very stubborn boil. That equates to a great deal of money lost for the medical industry. In 2015 I did a complete series of doctors visits simply to have everything tested and see if I had any issues I should address. My results were just slightly elevated cholesterol and deficient in vitamin D. All my other tests came back clear as a bell including my mammogram and pap smear. I am 60 years old.

      During all those diagnosis visits, I would sit in the examining rooms adding up the thousands and thousands of dollars invested in the medical equipment alone. Those exuberant expenses aren’t paid for by healthy people. I call it the Big 3; big business, big pharma and big government thereby making it a ‘huge’ uphill battle. You could actually call it the Big 4 because the first three are pulling the strings of the 4th; the media.


    We too long for the day that healthcare providers will have the majority voice on the optimal diet, but until then, we can have that one voice crying in the wilderness! Even one soul won will put out the word exponentially through their circle of influence, and so on and so on! One patient at a time. People still put a lot of stock on the word of a trusted physician, especially one who practices what he or she preaches. Physicians ought to promote what they have actually experienced. Their message will be that much more impactful.
    Walk your talk, talk your walk,

  • John Duda

    Dr. Gregor, could you please let us know where to find the interesting figure with phytonutrient compounds from different vegetables? I would love to use that when I talk to my patients about the benefits of a vegan diet. 

    • Michael Greger M.D.

       I’ve added the source above and placed the graphic in supplementary materials. Too bad we can’t squeeze all 10,000-or-so in :)

  • Julia LaCava

    Excellent lecture you gave at the Nat’l Animal Rights Conference!!  Thank you for all you do.  It is very frustrating when I suggest the benefits of a plant-based diet to people, only to hear them reply that their physician tells them to keep eating lean meats and dairy…end of story.  They are done listening to anything I have to say.

  • Louise Berman

    I am a new vegan with diabetes Type 2. I am told I need to take B12 supplements but the pills seem to have hugely more than required. However my diabetes website pointed me to research that taking the drug metformin which I am on means you need much more B12 supplement. My pharmacist recommended 1mg a day which seems ridiculously more than than the 5mcg my Dr recommended or the 2.4mcg per day that other sites recommend. The pharmacist said that 1mg a day is fine as it is water soluble and one excretes what is not required. Very confused. Help

  • abeleehane

    B12 is not well absorbed, thus the larger pills. Since it is stored in the liver and there is no known detrimental effect for overdosing, you should be fine with the 1200mcg a few times a week .

  • Leah Stolar

    Dr. Greger, I had the pleasure of meeting you at Health Fest in Marshall, Tx and loved your presentation Uprooting the Leading Causes of Death and bought several CDs. I eat a low fat, whole food, plant-based diet but recently my total cholesterol and LDL shot up. A year ago I was at 183 and LDL of 101, not as good as I’d like, but as low as I think I can get. This week I retested and it was 225 and LDL 137, HDL 70. I exercise strenuously 30 minutes/day and my BMI is 21. I am 52 years old. So . . . I’m wondering what other factors are at play and whether stress is a factor. Have you reviewed literature on the relationship between cholesterol and stress?

    • I have the pleasure of taking care of patients at the McDougall Whole Foods program. One area you might look at is fruit and fructose consumption. Whereas “glucose” is our bodies fuel and burned by every cell in the body… “fructose” is only metabolized by the liver to uric acid, inflammatory aldehydes, triglycerides, cholesterol and glycogen. I have had several patients adjust their fruit consumption down or reduce consumption of recovery drinks or bars which might contain fructose. Even though your LDL is high your LDL/HDL ratio is good. As far as stress goes… it has been linked to a wide range of disorders… in my almost 40 years of practicing medicine I’ve been more impressed by the fact that when patients are under stress they eat and exercise differently. Keep up the good habits and stay tuned to As an athlete you might enjoy Scott Jurek’s book, Eat Run. He has recipes he uses for recovery.

    • Jackie Thomas

      What changed? Stress?

  • judithv

    As a newly diagnosed breast cancer patient, I was hoping to find specific information regarding treatment in this video. I did not.
    I have followed a vegetarian diet for over 15 years, and a mostly plant based diet for the last three. Additionally I take multiple vitamins everyday, go to exercise classes at the gym 4 days a week and do not smoke, drink alcohol, coffee, tea or soft drinks. I still developed breast cancer. Stop telling people that this will not happen if they will only make better choices.

    • GreenLight

      I’m a vegan going on 6 months now. What I’ve garnered from all I’ve read is that it improves your odds against diseases. There are no gaurantees in life. No one here or anywhere has stated illness will not happen. I can tell you since I’ve changed my diet to entirely WFPB I feel so much better on so many levels. For one, I was borderline diabetic with very high cholesterol. Not anymore. That alone makes it worth it to me.
      I wish you well!

  • Maureen

    I have been listening to many of your videos and I´m always impressed and schoked as to why we don´t know so much more. Thank you, thank you, thank you…. What about juicing, which seems to be a new fad?

  • A plant based diet contains over 100,000 different disease preventing nutrients! I love it!

  • Karoline Müller

    I switched to a plant based diet nearly 3 years ago, lost 70 lbs and feel a lot better. One thing is still bothering me: I easily get cold. Right now I’m sitting in 80 degree F in shirt&shorts and feel comfortable. But at work, I’m wearing winter clothes and am still freezing. 2 weeks ago it hit me and I actually got a cold and sick. Any thing I could do?

    • Karoline Müller

      Additional info: I came to healthy eating listening to Dr. McDougall and then many more through his Advanced Study Weekends. I’m eating mostly whole plant and lately really ramped up my green leaves consumption. I’m easily constipated even on a whole plant diet. I’m now thankful for this near instant feedback.

  • Paul

    Dear Doc, I suffer from fluctuating blood pressure. It’s high in the mornings and drops to low BP around noon and rises again bY night. What would be Your advice for this issue? – Paul

    • JacquieRN

      Hi Paul, as you can see I am not the “Doc”!

      Is this an ongoing issue of fluctuations? For how long? How high? How low? Do you have any other health problems? Caffeine use? Tobacco Use? Stressed? Do you work at night or sleep at night-so morning for you is? In other words need some more information.

      The BP does normally have fluctuations throughout the day usually in pattern of: normally lower at night while sleeping. BP starts to rise a few hrs. before you wake up. BP continues to rise during the day, usually peaking in the middle of the afternoon. Then in the late afternoon and evening, BP begins dropping again.

  • Alice

    Hi Guys,
    My Dr recently commented on my Orange Palms and said I most probably have carotenemia- I eat a lot of coloured vegetables because I eat salads and cooked veg every day and I like my food to be colorful.
    I was trying to find out which fruits and veg I should cut out to reduce the orangeness… I eat carrots, including the purple variety, pumpkin, beetroot, red and yellow capsicums, tomatoes and sun dried tomatoes, and I have strawberries/ other berries/ mandarines at least once a wk- do I need to cut out all of these or just carrots?
    One source I found even said that spinach and broccoli where high in Carotene! Can you shed some light?

    Does gmo soybean beneficial on human health?

    • Toxins

      Please stay tuned for Dr. Greger’s upcoming videos on soy and GMO.

  • Hippocrates Raw Guru

    What do you mean “sometimes”… The final note should read… “ALWAYS BETTER”!

  • One Single Act

    How perfect are berries (as well as most fruit) for the human design. Nutrient for nutrient, they match almost exactly the same as the nutrients in human breast milk. They draw you in with bright colors, wonderful smells, and beg to be eaten. And the tree or bush they come from keeps on living and giving to the next creature who passes by. Sounds like the perfect food for the human design.

  • Moran

    Hi Doctor,
    Does irradiation of spices and vegetables (like garlic, onions, potatos, etc.) before marketing to the public lowers the amount of antioxident in them?
    Thank you!

    • Joseph Gonzales R.D.

      Hi Moran. That’s a good question I think the antioxidant content remains. I am not sure if they are testing irradiated black pepper, but in this video it appears healthful. I couldn’t find any research perhaps others know? Feel free to post some research if you come across anything. Sorry I cannot provide more.

  • Craig

    dr. gregor is the best. ornish too. I’m paleo for three years now, but my ldl’s sky-rocketed. i’m going to change the proportion of my diet to even more plants, and less animal. thanks, Craig.

  • Nancy Hammett

    So pleased and grateful for all this important information! Thank you!

  • Απόστολος Στάβλος

    Hello Doctor and thank you so much for your time and effort on this. Here’s my question.

    Say that i am with a doctor or another health professional and they try to warn me about the dangers of a vegan diet. You see, these people won’t fall for a “studies have shown…” argument, because they are supposed to know studies better than me. So i need something that is convincing, legitimate and serious for them. Something short enough to be used in a spoken conversation. I tried to used the American College of Cardiology once, but i got the response “neah… those are just two or three ignorants who are dangerous” :/

    • Thea

      My 2 cents is: Someone who is committed to not learning about the nutritional science will not be swayed by anything you say. However, if I had to pick something to say, I would repeat one of Dr. Greger’s points:
      “There’s only one diet that’s ever been proven to reverse heart disease in the majority of patients—a diet centered around whole plant foods. So, anytime anyone tries to sell you on some new diet, do me a favor. Ask them one simple question: “Has it been proven to reverse heart disease—you know, the number one reason you, and all your loved ones, will die?” If the answer is “No,” why would you even consider it, right? Only one diet has ever been proven to do that. That’s not cherry-picking—there’s only one cherry.
      In fact, if that’s all a plant-based diet could do—reverse the number one killer of men and women, shouldn’t that be the default diet, until proven otherwise? And, the fact that it can also be effective in preventing, arresting, or reversing other leading killers—like type 2 diabetes, and hypertension—would seem to make the case for plant-based eating simply overwhelming.” from:

      • Απόστολος Στάβλος

        Well, that’s true. I did use this argument a few days ago, when i got my son his Poliomyelitis shot. He said that, of course a plant based diet would save lives and that is nutritionally “useful”, but this doesn’t mean we should abolish all other kinds of food (meaning, animal food). For once again he pointed to the “balance” thing: You should eat a moderate amount of all kinds of food because feeding exclusively on plants will sooner or later cause a deficiency of iron, vitamins and calcium and “your son will be in serious danger, weak and jealous of what other kids eat”. You see, this is frustrating…

        • Thea

          That type of reply demonstrates that a) this person did not actually absorb what you said and b) is extremely ignorant about nutrition. Such a shame as medical professionals should be the ones leading the way here…
          You may know this already, but just in case it will make you feel any better, here is a NuturitonFacts video showing that omnivores end up with more nutritional deficiencies than vegans:
          Also, I don’t know if this will be of interest to you, but there are two recommendations I often make when people ask nutrition questions about kids. You didn’t ask. Just ignore if this is presumptuous. One recommendation is to check out the site Vegetarian Resource Group, VRG, which Dr. Greger has spoken favorably of at one point. They have a whole section on kids, including a particular overview article I like. Here are the links: Overview: and Summary Nutrition Article: The other resource is a book that Dr. Greger recommends in his book. The book is called Becoming Vegan. The Express Edition has a chapter on kid nutrition needs. You might find that helpful too. Now that I think about it, PCRM, has some great kid nutrition info, but I don’t have any links handy at the moment.
          Good luck dealing with those doctors. I tend to prep myself ahead of time before I go in, reminding myself that doctors are great for some things and not for others and I need to draw the line on what the doctor is allowed to influence to only those areas doctors are trained in.
