Question: “I have always thought that cholesterol was bad for you; but then I heard someone talk about “good” cholesterol. Is there such a thing as “good” cholesterol?”

Answer: Cholesterol in itself is not “bad” for you; in fact, your body needs a certain amount of cholesterol in order to function. Cholesterol is a waxy, fat-like substance necessary for the production of hormones, Vitamin D and other substances. Meats, dairy products and eggs contain cholesterol; but diet accounts for only 25% of your total cholesterol with the remainder being synthesized by the liver and other cells in your body.

Triglycerides are another form of fat shown to contribute to heart disease and require monitoring as well. There are two basic types of cholesterol; LDL, referred to as the “bad” cholesterol and HDL or “good” cholesterol:

LDL (Bad) Cholesterol

LDL is considered bad for you because high levels of LDL in the blood can combine with other substances to form a thick, hard deposit called plaque. Plaque builds up over time and causes a narrowing and hardening of the arteries. When the arteries become narrow, a small clot can form and lead to total blockage of the artery resulting in a stroke (brain) or a heart attack (heart).

HDL (Good) Cholesterol

HDL cholesterol is considered good for you because it has the ability to help the body “clean up” the plaque and remove it from the artery walls. High levels of HDL can decrease the risk of heart attack or stroke and low levels of HDL are a risk factor for heart attack and stroke.

Because cholesterol and triglycerides are a risk factor for heart attack and stroke, you should see your doctor and have a lipid panel checked. Below is a summary of desirable lipid values taken from the American Heart Association web site: http://www.heart.org

Total Cholesterol <200>240 High
LDL Cholesterol <100>160 High
HDL Cholesterol <>60 Protective
Triglycerides <150>200 High

So there you have it, “The Good (HDL), the Bad (LDL), and the Ugly (Triglycerides)” about cholesterol.
