(Ivanhoe Newswire) -- If you’re not one of the 17 percent of Americans
who have high cholesterol, you may consider yourself healthy overall. New
research that shows some good cholesterol can negatively affect your health may
change your mind.
Conventional wisdom says having high levels of good cholesterol, or HDL, and low
levels of bad cholesterol, or LDL, plays a large role in keeping you healthy. A
recent study challenges that idea. After reviewing published data on the topic
of good versus bad cholesterol, researchers at the University of Chicago found
even when blood levels of HDL are comparable, HDL present in people with certain
chronic diseases differs from HDL in healthy people. They discovered this is
because normal HDL reduces inflammation while dysfunctional HDL doesn’t.
“For many years, HDL has been viewed as good cholesterol and has generated a
false perception that the more HDL in the blood, the better,” first study author
Angelo Scanu, M.D., of the University of Chicago in Chicago, Ill., was quoted as
saying. “It is now apparent that subjects with high HDL are not necessarily
protected from heart problems and should ask their doctor to find out whether
their HDL is good or bad.”
High levels of LDL or total cholesterol are already known to be indicators of
increased risk for heart disease.
