A doctor explains that HDL is the "good" cholesterol.

Definition

Noun: A type of lipoprotein that carries cholesterol from the body's tissues back to the liver for processing or removal.

Elevated levels of this substance in the blood are considered beneficial and are associated with a lower risk of cardiovascular diseases.
