Dr. Michael Greger–What do we make of him?

Dr. GregerA while ago I came across videos by Dr. Michael Greger. I was impressed by his ability to produce these 3-4 minute features every day. The science was sound and the production values high. I started to watch every day and it soon became clear that there was an agenda here. Every video either spoke about the benefits of some plant component in the diet or the harm caused by some chemical in animal products. It turns out that Dr. Greger has swallowed the vegan philosophy hook, line and sinker; not that there’s anything wrong with that. He promotes veganism with religious fervour and has forged a career speaking on health issues, including guesting on the Dr. Oz Show. Surely that is the ultimate recognition of scientific expertise! He also was an expert witness in on Oprah’s behalf when she was sued by meat ranchers for defaming hamburger. Dr. Greger claims to donate all profits from books and speaking engagements to charity, certainly a noble commitment.

You will never see Dr. Greger refer to a study that shows anything positive about meat, but you will see plenty of studies that point out the pitfalls of consuming animal products. While there is some zealotry here, the studies that Dr. Greger enthusiastically talks about are from respected journals and merit our attention. I think his videos are worth watching, but keep in mind that there is some cherry picking of data. Of course that doesn’t mean the cherries he picks are rotten; they’re fine. Here is his latest; you can also sign up for a free subscription to his daily videos.

    It’s interesting how people go on about nutrients, especially this ‘huntress’ character (bias? surely not..).

    They are right. Pound for pound, animal products are high in nutrients, at least some of them. They’re pretty good at protein, iron, calcium. Problem is, pound for pound animal products also have the largest amount of harmful bacteria, carcinogens etc.

    Containing nutrients does NOT mean ‘healthy’.

    I’ve watched many of Dr Greger’s vlogs and agree he cites credible, respected sources. He also does show his bias on some and even regular readers and supporters have reluctantly called him on it at times and with all due respect at times it’s the good doctor’s rebuttal that’s weak. I follow his blog as part of many sources of information. I learned long ago to stay open to all sides of an argument or you might miss something valuable.

    I strongly believe everyone should educate themselves from different, credible sources and do what makes sense and works for them. I agree it’s not one size fits all. Let’s just respect others right to choose instead fighting to be right.

    Are you all serious? Balance is the key. You don’t throw the baby out with the bath water. My brothers and sisters all gave up eggs and cutting down on saturated fats and they are all sick, on medication, and over weight. The culprit is hydrogenated fats, sugar consumption and all the chemicals added to our foods and water either directly or through eating animals that have been injected or fed them. You don’t cut out all fat but the wrong kind of fats from unhealthy animals. And if everyone would just stop eating processed foods and drink filtered water they’d have a 75% improvement in their health. We also are individuals and have different requirements to be our healthiest. One size does not fit all.

    Sure, there might be some Studies that show that meat consumption might be helpful in some ways, pound for pound plant-based diet is not only sustainable has the highest concentration of nutrients and antioxidants. Food is a packaged deal. If you eat pounds of meat day after day versus eating pounds of vegetables day after day which do you think would cause more disease? Cause more harm to the environment?

    You can’t fault Dr. Greger for taking a strong side. However, From all the people I’ve seen or read bashing him, they seem to lack any rebuttal that legitimately disproves his findings.

    Unfortunately, it is the meat and dairy that is killing Americans with heart disease, cancer and diabetes. That is incontrovertible. So why would one proselytize on behalf of the root problem? Meat needs to be demonized. The animals cost us too much, they are poorly treated, they harm the environment, eat too much, consume too many drugs and hormones and are one unending disaster. IMO. Americans are going to have to jump on Greger’s band wagon, or die. And their sick habits and lifestyle is spreading around the world, like a great tsunami of animal fat.

      “Unfortunately, it is the meat and dairy that is killing Americans with heart disease, cancer and diabetes. That is incontrovertible.”

      Then, you ought to earn the Nobel Prize in Physiology and Medicine. Others investigators haven’t been so lucky and are still unsure of your statement.

      • Joe Mitchell says:

        People want to justify eating meat because heaven forbid they can’t have their steak and eggs with cheese and a side of bacon. Connect the dots people, it’s science but it’s not rocket science. What does every doctor on the planet ever recommend for good health? Eating more fruits and veggies. SMH

    • Huntress says:

      The Adventist and EPIC study data finds no difference in mortality between vegetarians and omnis. And animal food consumption is down 75lbs per person, per year in the US since 1950 (according to the USDA’s consumption report). What’s up is sugar, vegetable oil and grain consumption (and fruit and veggies too). So you do the math, can the animal food actually be responsible for the disease epidemic of the last half century?


      • Lou says:

        Vegetarians and omnivores BOTH consume animal products… However, there IS a difference in mortality between VEGANS and omnivores – which is why The American Dietetic Association, The American Medical Association, Harvard Med School, The National Academy of Sciences, the American Cancer Society, The American Heart Association and National Institutes of Health ALL now advocate a plant based diet – I guess they’re not as good as you at interpreting the meta analyses… BTW all of the studies Dr Greger cites are peer reviewed and published in well respected journals.

        • Huntress says:

          No, there isn’t a difference in mortality. And FWIW, the groups you cite don’t advocate a plant based diet- they say that a plant based diet CAN be healthy. They still advocate omni diets.
