Cholesterol, essential ingredient for life, health and sex
Although cholesterol has a bad reputation for clogging the arteries, it’s not the enemy. Cholesterol is essential for life and health. It provides energy to cells, helps make cell membranes, and assists in the formation of sheaths around nerves. Plus, it plays a vital role in the production of the sex hormones testosterone, estrogen and progesterone, and other adrenal hormones like DHEA and cortisol.
While cholesterol is in some foods we eat, the liver manufactures most of it. In fact, each day our bodies churn out about 1000 milligrams of cholesterol, compared to the average dietary intake of about 325 milligrams for men or 220 milligrams for women.
No matter whether it comes from the liver or our diet, cholesterol and other dietary fats must move from the digestive system and into the cells to perform these terrific tasks. Fat must be packed into protein-covered particles that allow the fat to mix with the blood. These tiny particles are lipoproteins (lipid-or fat-plus protein).[The Doctor's Heart Cure, Al Sears, M.D.]
