Studies trying to convince people to consume their profitable industrial plant oils fats which are totally NON-Paleo.

Pufa sources attached!  Disgraceful sources!

Important to note that this does not disagree with the Paleo diet, in fact to a certain extent it lends it even more support as grass fed beef is actually quite low in saturated fat compared to grain fed.

Danaei, 2009-5% additional mortality risk for each 1% calories exchanging PUFA for SFA

This is also a metaanalysis, so the same issues apply.  Also, the statement, which appears to be a quote from wikipedia, doesn't seem to be entirely accurate; the additional risk varied from 5% to 1% depending on age category.  Perhaps most importantly, the authors don't seem to think replacement of saturated fatty acids has anything to do with it:  "The interventions [sic] studies replaced dietary SFA with PUFA, hence the RRs measure the effect of replacement.  Effects of replacing PUFA for other macronutrients have not been evaluated in randomized inverventions [sic] studies.  However, evidence from cohort studies suggests that replacement of PUFA for carbohydrates, but not carbohydrates for SFA, would produce similar benefits, indicating that the measured benefits are due to PUFA."

Do you know if any of these are direct reports of single intervention studies, rather than metaanalyses?

Two big paradoxes in the world of 'sat fat is bad'. The 'French Paradox' where high levels of sat fat are (were) eaten and cardiovascular health is good and the 'Israeli Paradox' where they eat large quantities of soybean oil and the results are crap. (Note: This is a high omega 6 and not high omega 3 diet)
