Have not been able to find any and have read researchers state that such studies don't exist. Can you list them please, if they exist. Here's what I've come across: Numerous trials have been conducted since the early sixties, when the AHA began pushing the idea that saturated fat was involved in the pathogenesis of CHD. Only three of these trials were of the double-blind variety - the National Diet-Heart Study , the Los Angeles Veterans Administration Study and the Minnesota Survey (19-21). All of these trials involved the substitution of highly saturated animal fats with polyunsaturated vegetable fats (well-known for their ability to lower blood cholesterol levels) and all completely failed to show any benefit from the reduction in saturated fats. This was despite the fact that saturated fat restriction consistently lowered cholesterol levels among the treatment groups of these studies. The Veterans Administration Study did show a noteworthy decrease in CHD fatalities among the treatment group, but the results were biased by a significantly higher proportion of heavy smokers in the control group. Despite this advantage to the treatment group, they still suffered a significantly higher frequency of cancer deaths which neutralized the mortality reduction from CHD. Total mortality between the two groups after 8 years was virtually identical. One has to wonder what the result would have been had there been a similar proportion of heavy smokers in both treatment and control groups. 19 National Diet Heart Study. Final report.
