studies of this topic point out". Hal Finney said that "This looks to
have been well within "mainstream alternative" (if that means anything)

"Similar claims are made in the books by Dr. Neal Barnard".

"ct" <>'s pointed me to actual evidence:
I was somewhat shocked at the contrast there between the conclusion:

"There is overwhelming evidence that reductions in saturated fat, dietary
cholesterol, and weight offer the most effective dietary strategies for
reducing total cholesterol, LDL-C levels, and cardiovascular risk."
