This is due to the long held belief that HDL cholesterol reduces heart disease risk by “picking up” artery clogging cholesterol from circulation.

A new study utilizing modern genetic testing is challenging this theory, finding that there may not be a direct cause-and-effect relationship between reduced heart disease risk and high HDL cholesterol levels. Study findings indicate the high HDL levels themselves may not be protective on their own. These high HDL levels may be an indicator of something else reducing heart disease risk.
