A high level of blood cholesterol is directly related to atherosclerosis and coronary artery heart disease. According to the National Institute of Health, coronary artery disease (atherosclerosis of the coronary arteries) is the leading cause of death in the United States.
The American Heart Association's Nutrition Committee strongly advises the following guidelines for fat intake in those over the age of 2:
Limit total fat intake to less than 25–35 percent of your total calories each day;
The remaining fat should come from sources of monounsaturated and polyunsaturated fats such as nuts, seeds, fish and vegetable oils; and
Limit cholesterol intake to less than 300 mg per day, for most people. If you have coronary heart disease or your LDL cholesterol level is 100 mg/dL or greater, limit your cholesterol intake to less than 200 milligrams a day.
Limit trans fat intake to less than 1 percent of total daily calories;
Limit saturated fat intake to less than 7 percent of total daily calories;
Cholesterol supplements support the health of arterial walls by preventing lipid peroxidation. Positively effect platelet function, which is an important factor in supporting healthy blood flow. They help to maintain healthy blood pressure levels already within normal range.
