Nutrition therapy for dyslipidemia.

National guidelines indicate patients with elevated low- density lipoprotein cholesterol should consume less than 7% of calories from saturated fat and less than 200 mg of cholesterol. Trans fatty acids should also be limited. Incorporation of functional foods, such as stanol-containing margarine, soy products, and soluble fiber-rich cereals and vegetables can provide further benefit. In addition to weight loss and physical activity, individuals with hypertriglyceridemia benefit from a diet moderate in fat and carbohydrate rather than a low-fat diet. Including monounsaturated or omega-3 fatty acids lowers serum triglycerides. Many of the dietary strategies to optimize serum lipids also contribute to glycemic control in patients with diabetes mellitus.
