    As it stands, I am not finding the presented argument on heart attacks and cholesterol to be persuasive since heart disease is multi-factorial. Therefore, there is always a non-zero probability that someone with a very low cholesterol could get a heart attack.

    So what does it prove if a study reports that some who have low cholesterol get heart attacks. It could even be that blood cholesterol level matters to a point, but then fails to matter below a certain threshold.

    Average blood cholesterol level is a useful metric to make predictions about populations, but of limited value in interpreting an individuals health. I feel we should keep this point in mind when interpreting these studies.

    This is extremely interesting stuff. You can read the whole agribusiness article here:

    The author, who seems to conclude that since were not really sure of anything, it’s best just to merrily continue stuffing ourselves with animal flesh (and for good measure he throws in a pic of a big slab of red meat for the slow-witted among us). He does though quote the bit that the current guidelines might not be low enough.

    A lot of pro-meat/anti-veg websites use information like this study (or “accepted” cholesterol guidelines) to propose that cholesterol is not really a risk factor for heart disease after all. Or, as even our agribusiness friend quoted in his article, maybe it could be that the current guidelines might not be low enough.

  • Great video!
    So what’s the (almost) dead-proof cholesterol level then?
    150 for total?
    or even lower…?

  • Mike Quinoa


    I’m not sure of the optimum LDL level, but from what I’ve read, no-one in the long-running Framingham Heart Study with a total cholesterol level of 150 or below has ever had a heart attack.

  • yeah, I have heard that too but from the chart that shows at about 30 sec in the video one can see that the average total cholesterol of hospitalized patients was 170,1 +/-48,2
    which should mean that at least some of them had it below 150…
    (one should read the actual study to be sure but at least so it looks from the chart)

    My mom has been eating vegan/plant-based for sox months. She has lost 15 pounds,but her cholesterol has not dropped. Any thoughts? We are confused.

      everyone is, nutrition science has no clue. even if blogs like this choosing the studies that fits in their agenda would like you to believe. i’ve searched the whole video archive, zero videos on kefir, yogurt, whey.. why? because there are no negative studies on those, and the positives dont fit into their agenda.

      • Toxins

        All of these foods are not health promoting, there are not studies showing these foods prevent chronic disease. The opposite is true.

        daniel: re: “because there are no negative studies on those” This is not correct. All of the foods you listed are dairy foods. This site covers the problems of dairy in particular and animal protein in general – in great depth – showing just some of the many studies which show how harmful those foods are.

        as for “positives” of dairy: As Toxins points out – It’s awfully hard to find any positive. Dairy does not prevent chronic diseases – in fact the opposite is true.

    What do you think about the estrogen generation effects of an overly soy diet?
