cells. Despite its reputation, cholesterol is essential for good health. But
misconceptions are common. Learning cholesterol facts helps you understand its
function and effects on health.
Cholesterol Types
There are two main types of cholesterol:
·
LDL Cholesterol: "Bad"
cholesterol that can build up on artery walls.
·
HDL Cholesterol: "Good"
cholesterol that removes LDL buildup.
