More evidence that it isn't high cholesterol that kills your heart, it's high levels of bad LDL cholesterol that gets you.

Having a high level of HDL cholesterol – the good cholesterol – is more important than having a low level of LDL – the bad cholesterol – in protecting individuals from heart attack, according to a study published in the March issue of American Heart Journal by researchers from the Indiana University School of Medicine and pharmaceutical company GlaxoSmithKline, Inc.

The researchers looked at the history of heart disease, age, sex, race, weight and other heart disease risk factors in almost 7,000 patients. The patients were predominately inner city residents and included a large number of African Americans, women, smokers and overweight people. The researchers found the strongest predictor of future heart attack was previous heart disease; age was the second strongest predictor and the third strongest predictor was HDL level.

"Most of the drugs that lower LDL also tend to raise HDL so until our study, when a person's health improved, you couldn't tell if that was due to lowering of the LDL or raising the HDL level," says study senior author William Tierney, M.D., IU Chancellor's Professor of Medicine and a Regenstrief Institute, Inc. research scientist. "We now know that more good cholesterol is more important than less bad cholesterol.

This has been claimed for a long time but some folks are slow I guess. The ealier post Eat Wild discussed the use of HDL as a medication. This has long been a claim of pastured beef and dairy products as well. Such products have less total fat than grain fed animals but more importantly it has higher levels of HDL cholesterol - less fat total but more good fat.
