Cholesterol

Despite what some people believe, not all cholesterol is bad and you are not always what you eat, particularly if you are a vegetarian. In fact, cholesterol is essential to life, being a primary component of the membrane that surrounds every cell. It is also the precursor biochemical from which the body synthesizes bile acids, steroid hormones, and vitamin D. Cholesterol circulates in the bloodstream and is manufactured by the liver and several other organs.
