Cholesterol is a natural sterol that is produced in the liver; it is a vital part of a healthy body as it acts as a structural component of the cell membranes and helps the body to absorb various vitamins. Cholesterol becomes a problem when there is too much in the body.
Sometimes this is due to some hereditary condition but in most cases it is caused by what the person eats. Animals products, especially fat and dairy products have cholesterol in them. Eating too much of these types of foods or not exercising enough can lead to high cholesterol.
