In the last few years the concern about cholesterol dramatically increased. In fact, some cholesterol is necessary for life. Here's the reason why.
Cholesterol is a fatty, wax-like substance found in all body cells.
Our bodies use it to build cell membranes and to produce important hormones. Even if you are on a cholesterol-free diet, your liver manufactures cholesterol to keep your body supplied. If you have too much cholesterol and saturated fat in your diet it may cause elevated blood cholesterol. Excess cholesterol clogs your arteries. This is called arteriosclerosis, and it impairs blood flow.
