The liver manufactures cholesterol from the breakdown products of carbohydrates and fats, particularly saturated fats. Cholesterol is also stored in the liver. Since all animals manufacture cholesterol and plants do not, dietary cholesterol is only found in foods from animal sources. This includes any type of meat, fish, eggs, or dairy products. Although cholesterol and fat are two different substances, generally the more fat that is removed from animal foods, the less cholesterol they contain.
Lean meats contain less cholesterol than fatty meats.
And nonfat or skim milk, which contains virtually no fat, contains virtually no cholesterol. As fruits, vegetables, grains, and nuts are plants, they initially contain no cholesterol. However, it may be added to prepared foods. Other kinds of foods also affect one s serum-cholesterol level. These are foods with saturated fats, unsaturated fats, and fiber.
