Researchers find 95 genes affecting cholesterol

A scan of all the human DNA has turned up 95 genes that affect blood cholesterol, including a few affected by drugs on the market and others that might be the basis of new drugs, researchers said on Wednesday.

The consumer magazine published a report on Tuesday highlighting the U.S. Food and Drug Administration's lack of power to regulate such supplements, and said the agency rarely uses what little power it does have.
