    Increasing polyunsaturated fats lowers risk of heart disease?? (New study)

    Shop Now
    Has anyone seen &/or analyzed a new study (meta-analysis) just published by Harvard School of Public Health in which they claim that when people consumed more polyunsaturated fats and fewer saturated fats, their risk of heart disease decreased? Just when I have finally been convinced that Primal/Paleo eating is the healthiest, this study comes out. PLEASE read the article in the link below and COMMENT!!

    They cherry-picked their studies, their studies weren't really comparable, and many of the studies were poorly controlled to boot. What's more, the effect they managed to produce with all their data manipulation was still pretty small.

    Also, this is a double post, here and in Primal Research. It probably belongs there rather than here, so a mod might want to delete this version.
    Give me liberty. Exploration of other options will be vigorously discouraged.

    "RCTs were identified by systematic searches of multiple online databases through June 2009, grey literature sources, hand-searching related articles and citations, and direct contacts with experts to identify potentially unpublished trials. "

    Agreed with MG. Holy cherry-pick, batman! Even if they had actually tried to maintain some measure of objectivity and honesty, all this would prove is that omega 3 deficient people are more prone to heart disease than omega 3 sufficient people with some extra omega 6. It's not the saturated fat's fault and it's not the extra omega 6 that is the hero. Judging by the little reduction they got and the proven effect of omega 3 sufficiency it looks like the omega 6 is actually doing some harm. The "saturated fat" group wouldn't even be able to produce anti-inflammatory eicosanoids properly. You have to control for TYPE of PUFA and you can't just mash two (plus subsets of significance) distinct fatty acids together as if they are one and the same. We know that a delicate ratio needs to be maintained and the complete lack of acknowledgment of the fact is one more example of junk science.

    But considering the variance of studies and the lack of objectivity pointed out in whole health source we can discard this entirely. That's just not how you go about conducting a study. Especially one which you then go on to give advice to people based on.
