Protein and Heart Disease

Protein and Heart Disease


“Protein and Heart Disease” We know that the quality and
quantity of fat is tightly correlated with the risk of our
#1 killer, heart disease. But what about protein? Out of Harvard recently: Dietary Protein and Risk of Ischemic
Heart Disease in Middle-aged Men. Independent of source,
and independent of fat, do you think total protein
intake was associated with more heart disease, less heart disease, or no difference? And the answer they found was: no difference. The quantity didn’t seem to matter. But what about the quality,
the source of the protein? They observed no association
between total dietary protein and risk of total heart
disease in this group of men; however, higher intake of animal
protein may be associated with increased rise of ischemic
heart disease in “healthy men” meaning those without hypertension,
high cholesterol, and diabetes. Healthy only in quotes, though, given their higher risk of heart disease due to their consumption
of animal protein. They’ve also observed a
significant inverse association between higher vegetable protein
intake and risk of fatal heart disease. So more plants, less heart disease, meaning the more plants
and fewer animals one eats would appear to be better for the heart, even independent of the fat issue. So the benefits of a plant-
based diet may extend beyond just avoiding saturated animal fat. But isn’t protein just protein, though? I mean, how does your body know if
it’s coming from a plant or an animal? Well, proteins are made up
of a string of amino acids, and there are some amino acids more
common in plants than in animals, particularly glutamic acid, which a study published in the Journal of
the American Heart Association was found, for example, to potentially have independent blood
pressure-lowering effects, which may contribute
to the inverse relation between vegetable protein
to blood pressure, meaning high plants – low pressure. Their data generally reinforced
current recommendations for high intake of vegetable products as a part of comprehensive
nutritional lifestyle approaches for preventing and controlling major
established cardiovascular risk factors and epidemic cardiovascular disease.

  1. @IResonateWithU I hope so too. The paleo crowd uses that argument to justify their habits and that myth needs to stop.

  2. Show me proof and not another epidemiological study and then we'll talk proof of anything

  3. Sorry, I didn't get what you were saying. I get what you were saying now. Those studies where showing soy fights cancer are likely using conventional soy. My guess is that these studies are actually using conventional pesticide-laden veg protein. Colin Campbell addresses this grass-fed organic meat idea in the extra clips on the Forkes Over Knives DVD and says that there is no difference.

  4. You know, I'm sorry to generalize here, but a lot of these paleo adopters are meatheads. I mean much like the brainless gym meatheads. They buy are always ready to buy into the latest fad craze. I've been in these circles for 20 years and I've seen quite a bit. Creatine, chromium, HGH, the fads come, and the fads go. This audience is ready to jump on any superficial quick fix. Of course, they are not all ignorant. I've met smart ones but by and large, the stereotype of meathead fits.

  5. leukocytosis occurs regardless of grass fed, raw milk, whatever excuse someone wants to use.
    animal protein is Unnatural to a human being.

    weren't the animals in asia in the 70's all grass fed, which were studied in the china study? t colin campbell has said that whatever the cow has eaten has nothing to do with how bad all animal protein is to a human being.

  6. for those who are vegans, I'm a vegan wanna-be, i don't want to take vegetable protein powders, I am not active nor do i want to be active, how can i get enough protein without eating too many calories?…any site you guys can link me to?….thanks

  7. Hey doc, just for the sake of completeness and since you're discussing animal protein in general, why don't you also post the 26 year prospective study "Dietary protein and risk of ischemic heart disease in women" which involved 84 thousand women? Let me quote this from that study for you "Higher intakes of poultry, fish, and nuts were significantly associated with lower risk (of CHD)… ". Animal protein not too bad now is it?

  8. Since Australians only eat grass-fed beef, and their heart disease matches that of the USA, that should put it to rest for reasonable people.

    Grass-fed beef—–It’s apparently $24.00 a pound at wholefoods. Most people live in cities, and they're too poor for grass-fed beef, and they’ll not likely drive 1 ½ hours, or more, to buy reasonably priced steak only to drive all the way back with part of a quickly rotting, stinking corpse.

  9. Oh, the hidden agenda game? You think it's one sided? You know Mr. Greger here is (or was) an animal rights activist? Nutrition facts, right… You're welcome!

  10. That's awesome man, but please feel free to provide the links yourself. Not very polite handing others the burden of proving your points, is it? And if you're implying that even large scale studies can be skewed or biased, I agree with you, they can. (very common in vegan studies in my experience) Interestingly, that should make you a skeptic, not a cult member…

  11. Yes, through my own research, I was able to find out several of his videos were based on bad, misjudged, or distorted science. Several flukes indeed! But if you find them helpful who am I to stop you! 🙂 It was a pleasure talking with you too… have fun reinforcing your fantasies!

  12. Dr. Greger
    I would love to see a video on grass-fed cattle, it seems to be all the rage. People are dogmatically holding that as thier final argument against going vegan (even though they eat and will continue to eat conventional flesh) and although i say many things about how certain compounds are inherent in the meat or dairy itself regardless of farming practice they refuse to accept it…..

    HELP!!! Make a solid video on it…or if you have already then what is it called?

  14. AKK!
    The auto play worked faster than my fingers on that last comment. Sorry. I reposted under the mushroom vid.

  15. This study is a cohort of 43,960 men, so idk how can you draw causality from that, but more importantly, how do you know its the protein since it's just a follow up? i mean high animal protein diets are also high cholesterol and high saturated fat diets, even "lean meat" has small amounts of cholesterol. Unless u conducted a RCT, and u feed participants Hydrolyzed isolate whey protein, (which is very high in protein and has virtually 0 fat) don't tell me it causes heart disease. And there was a 2000 cohort similar study from harvard too, that didn't find that it increases HD, in fact replacing carbs with protein has a beneficial effect, and no it wasn't funded by the industry, and btw i'm vegan.

  16. i do eat meat, but also like vegetables, fruits, etc,…so what should be ˝neutral ˝˝ ratio meat:vegetables to have healthy meal ?
