What does HDL stand for in relation to fats?

High-density lipoprotein (HDL) is a type of cholesterol that plays a crucial role in cardiovascular health. It is often referred to as "good cholesterol" because it helps transport cholesterol from the arteries and other tissues back to the liver, where it can be processed and removed from the body. This action helps reduce the risk of heart disease and stroke by preventing the buildup of cholesterol in the arteries.

The term "lipoprotein" indicates that HDL is composed of lipids (fats) and proteins. The "high-density" descriptor refers to its density compared to other types of lipoproteins, such as low-density lipoprotein (LDL), which is considered "bad cholesterol" due to its role in plaque formation within the arteries. Understanding HDL's function in cholesterol transport and its protective effects on cardiovascular health is essential for promoting heart health through diet and lifestyle choices.
