The good, the bad, and the oxy

Forget "good" cholesterol and "bad" cholesterol, according to research presented at the American Chemical Society's national meeting in August, it's the oxy form of cholesterol we should be concerned with when it comes to cardiovascular health. Total "bad" cholesterol, low-density lipoprotein cholesterol (LDL), and the heart-healthy high-density lipoprotein "good" cholesterol (HDL) are important health indicators explained Zhen-Yu Chen of the Chinese University of Hong Kong, but he says that medicine should recognize that the less well known oxycholesterol is also important and should not be ignored. "Our work demonstrated that oxycholesterol boosts total cholesterol levels and promotes atherosclerosis [hardening of the arteries] more than non-oxidized cholesterol," Chen says.
