Cholesterol is one of the many substances created and used by our bodies to keep us healthy. Some of the cholesterol we need is produced naturally (and can be affected by hereditary factors), and some of it comes from the food we eat. There are two types of cholesterol — “good” and “bad.” It’s important to understand the difference, and to know the levels of good and bad cholesterol in your blood. Too much of one type or not enough of the other can put you at risk for coronary heart disease, heart attack or stroke.
