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

[oneuncoolmom]

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.

Thank you, Molecular Grokologist, for your analysis and explanation here and on your blogspot. It is so disheartening to know that researchers who should be high caliber (Harvard) and journal referrees defend studies like this. But, poor studies have been going on for decades as Gary Taubes discusses throughout Good Calories, Bad Calories. Onward with the Primal/Paleo diet.............
Thank you.

Oh, it's not my blog. I wish I could take credit for that, but I am not, alas, Stephan Guyenet.

We always have to take these "findings" with a grain of salt since:
(1. they are usually funded by pharma/agra companies (as admitted by the editor of the NEJM- his excuse being that they can't find any studies that aren't!) and studies are sometimes fraudulent. Example:

(2. The studies themselves are very often misrepresented in the media articles we read about them. Example:

I remember reading an article about the skewed world of scientific studies and how they're reported. The example was an incident involving a study by Vanderbilt University comparing St. John's Wort to Zoloft. The study read "St. John's Wort Ineffective for Depression". What they didn't bother to report was that Zoloft also tested completely ineffective for depression. They buried that bit!
