Cholesterol is a substance, found in the tissue and bloodstream of the body, which is critical for maintaining healthy cell function. Our bodies manufacture about 80 percent of our cholesterol supply, and we get the rest by eating certain foods, especially saturated fats. Within the body, cholesterol is transported through the bloodstream by being attached to protein packages called lipoproteins. The action of HDLs helps prevent the development of atherosclerosis, the major culprit in clogged arteries, which leads to coronary artery disease and stroke.
Cholesterol is measured through blood analysis.
First, a sample of blood is taken, either through a simple finger prick or by drawing blood from a vein. The sample is analyzed for total cholesterol and, if the need exists and the equipment is available, for LDLs and HDLs. Limit such foods as butter, hard cheeses, meat fat, and coconut, palm, and hydrogenated vegetable oils. Replace saturated fats with monounsaturated fats such as olive and canola oils. Read food labels carefully.
