Cholesterol is a soft waxy like material that is made in the liver of animals. Animal foods such as egg yolks, milk fat, organ meats, and shellfish, contain cholesterol too.
In many people, an elevated blood cholesterol level (hypercholesterolemia) is caused by excessive intake of foods high in saturated fats, cholesterol, and calories. Reducing intake of these products can reduce cholesterol levels. Limit intake to 300 milligrams of cholesterol per day.
