Whats the difference in “good” versus “bad” cholesterol?
About one-fourth to one-third of blood cholesterol is carried by high density lipoprotien (HDL). Often called the “good” cholesterol, high levels of HDL seem to protect against heart attack because it carries cholesterol away from the arteries and back to the liver where it is passed from the body. Optimal HDL levels are 40 mg/dL and higher.
