The Sydney Diet Heart Study was conducted in Australia from 1966-1973. It evaluated substituting "heart healthy" vegetable oils rich in PUFA Omega 6 fatty acids for that known evil ......Saturated fat!
The take home points:
"Advice to substitute polyunsaturated fats for saturated fats is a key component of worldwide dietary guidelines for coronary heart disease risk reduction. However, clinical benefits of the most abundant polyunsaturated fatty acid, omega 6 linoleic acid, have not been established. In this cohort, substituting dietary linoleic acid in place of saturated fats increased the rates of death from all causes, coronary heart disease, and cardiovascular disease. An updated meta-analysis of linoleic acid intervention trials showed no evidence of cardiovascular benefit. These findings could have important implications for worldwide dietary advice to substitute omega 6 linoleic acid, or polyunsaturated fats in general, for saturated fats."

This is a great video, taken from a lecture at the University of California, San Francisco by Dr. Lustig, Division of Endocrinology and Metabolism. It's very long, but does an excellent job of explaining how fat became the evil part of our diet and sugar was overlooked, how sugar (hfcs) consumption has closely followed the diabetes and obesity epidemic and the metabolic causes for this.

Is anyone surprised at this result? Well I guess those that still cling to the false belief that saturated fat in the diet is a risk for stroke and heart attack may be surprised. But for us in the Paleo/Primal movement the thought that sugary beverages + breaded food + deep frying with "heart healthy," lab created, PUFA's will increase your risk for stroke is an absolute no brainer!

Doesn't that make you think? World Health Organization data shows that as cholesterol increases, your risk of death goes DOWN!!!! These graphs are from the wonderful and insightful article by the British researcher Zoe Harcombe.
Remember, I was a national speaker for the most prescribed statin in the world. I have done a Fellowship in Advanced Lipid Analysis. There is no doubt in my mind that statins, while indicated for those with known coronary artery disease, are markedly over-prescribed for use in primary prevention.
