What is commonly referred to as "good cholesterol"?

The term "good cholesterol" refers to HDL cholesterol, which stands for high-density lipoprotein. HDL plays a crucial role in cardiovascular health because it helps transport cholesterol away from the arteries and back to the liver, where it can be processed and eliminated from the body. This action reduces the risk of plaque buildup in the arteries, which can lead to heart disease and stroke.

High levels of HDL cholesterol are associated with a lower risk of cardiovascular events, making it beneficial for heart health. In contrast, the other options represent different types of lipids that do not have the same protective effects as HDL. For example, LDL cholesterol is often termed "bad cholesterol" because it can contribute to the buildup of plaques in arteries, increasing heart disease risk. Triglycerides represent another type of fat in the blood, and while they are necessary for energy, high levels can also contribute to heart issues if they exceed normal ranges. Total cholesterol simply reflects the overall cholesterol level in the blood, which includes both HDL and LDL values but does not provide specific information about the cardiovascular health implications associated with different types of cholesterol.
