Guest guest Posted May 17, 2006 Report Share Posted May 17, 2006 While I was raking Pubmed I found this eloquent little abstract. It need not be said that this is the sort of bio-chemical evidence that is very hard to controvert, but apparently easy to ignore. Dietary polyunsaturated fatty acids and composition of human aortic plaques. Felton CV, Crook D, Davies MJ, Oliver MF. Wynn Institute for Metabolic Research, London, UK. How long-term dietary intake of essential fatty acids affects the fatty-acid content of aortic plaques is not clear. We compared the fatty-acid composition of aortic plaques with that of post-mortem serum and adipose tissue, in which essential fatty-acid content reflects dietary intake. Positive associations were found between serum and plaque omega 6 (r = 0.75) and omega 3 (r = 0.93) polyunsaturated fatty acids, and monounsaturates (r = 0.70), and also between adipose tissue and plaque omega 6 polyunsaturated fatty acids (r = 0.89). No associations were found with saturated fatty acids. These findings imply a direct influence of dietary polyunsaturated fatty acids on aortic plaque formation and suggest that current trends favouring increased intake of polyunsaturated fatty acids should be reconsidered.

Guest guest Posted May 18, 2006 Report Share Posted May 18, 2006 Hi : That is quite interesting. My understanding is that the Framingham data show that it is the CONSUMPTION of trans and saturated fats that causes the deposition of guck in the arteries. The Nurses' Health Study seems to confirm this because it found, after studying ~100,000 nurses for 30 years, that whatever substance it is that gets deposited in the arteries, the women who consumed the most polyunsaturated fats had the least heart disease. Source: " Healthy Women, Healthy Lives " - Willett. I also personally knew a professional photographer whose task it was in one of his assignments to photograph the inside of a pigs arteries as it was fed various different foods. He said that within thirty seconds (yes, seconds) of swallowing some high fat foods you could see the artery-clogging plaque starting to thicken. Weird. It doesn't even need to be absorbed to have the effect, apparently. Unfortunately he was unable to see the relevance of this in his own life, and he died a couple of years ago following a number of heart attacks and strokes.
