Why are some cholesteroles good?

Cholesterol is essential for various bodily functions, and it comes in different forms, primarily low-density lipoprotein (LDL) and high-density lipoprotein (HDL). HDL cholesterol is often referred to as "good" cholesterol because it helps transport cholesterol away from the arteries and back to the liver, where it's processed and eliminated. This process reduces the risk of cardiovascular diseases by preventing plaque buildup in the arteries. Conversely, high levels of LDL cholesterol can lead to Heart disease and other health issues, making the balance between these types critical for overall health.
