HDL cholesterol is often referred to as what type of cholesterol?

1. Bad cholesterol

2. Good cholesterol

3. Low-density cholesterol

4. High-density triglycerides

The correct answer is: Good cholesterol

HDL cholesterol is often referred to as "good cholesterol." The reason for this designation lies in its role in the body’s lipid profile and cardiovascular health. High-Density Lipoprotein (HDL) cholesterol helps transport cholesterol from the arteries and tissues back to the liver, where it can be processed and excreted. This process is beneficial because it lowers the levels of cholesterol that can accumulate in the arteries, which reduces the risk of atherosclerosis and cardiovascular diseases. In contrast, other forms of cholesterol, such as LDL (Low-Density Lipoprotein), are termed "bad cholesterol" because they are associated with transporting cholesterol to the tissues, which can lead to plaque buildup in the arteries. The distinction between HDL as "good" and LDL as "bad" is critical for understanding cholesterol management in health and fitness contexts.
