Dietary therapy for children with hypercholesterolemia.

Accumulating evidence clearly shows that atherosclerosis begins in youth. The National Cholesterol Education Program (NCEP) has recommended that children at high risk of developing coronary artery disease as adults be screened so that those with elevated low-density lipoprotein (LDL) cholesterol levels can be treated, primarily by modification of diet. The initial approach to these youthful patients is to use the NCEP step I diet. This diet provides calories and nutrients that support normal growth and development, but limits saturated fat and total fat intake to no more than 10 and 30 percent of total calories, respectively, and cholesterol intake to no more than 100 mg per 1,000 kcal per day, to a maximum of 300 mg. If the goal of reducing the LDL cholesterol level to below 130 mg per dL (3.35 mmol per L) is not achieved, the more restrictive step II diet should be initiated. However, the step II diet may not provide sufficient calories and nutrients to support normal growth and development; therefore, trained nutritionists may be required to effectively manage a child on this diet.
