The roles of HDL and LDL are as follows:
HDL (High-Density Lipoprotein): HDL is often referred to as the “good” cholesterol because it helps remove excess cholesterol from the bloodstream and transport it to the liver for processing and elimination. High levels of HDL are associated with a lower risk of heart disease.
LDL (Low-Density Lipoprotein): LDL is often called the “bad” cholesterol because it carries cholesterol from the liver to the body’s cells, including the arteries. If there is an excess of LDL in the bloodstream, it can lead to the buildup of cholesterol in the arterial walls, increasing the risk of atherosclerosis and heart disease.
