Why should healthy cholesterol levels that are already within normal limits be retained?
Cholesterol is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all cells. Cholesterol is essential for the formation of cell membranes. It is also plays a role in the synthesis of certain hormones, the formation of cholic acid in the liver (relating to the formation of bile salts), and is utilized by the skin in the support of skin integrity. However, a high level of cholesterol in the blood is a major risk factor for coronary heart disease, which can lead to a heart attack. High serum cholesterol levels are associated with coronary artery disease. Specifically, cholesterol deposits in the arteries develop into plaques that reduce or block blood flow. In addition, dense connective tissue deposits lead to arteries that become stiff and unyielding (sclerosis). Eventually, hard calcifications form. This is known as hardening of the arteries. Arteries that have lost flexibility are easily ruptured, and in the areas where plaques protrude into flowing blood, b
