The effect of dietary intervention on serum lipid levels in type 2 diabetes mellitus

Abstract

Dietary therapy is the cornerstone of lipid management in patients with type 2 diabetes mellitus. The key strategies are the reduction of intake of saturated fat, trans unsaturated fat and cholesterol, and the reduction of energy intake to promote weight loss. This approach will produce significant improvements in the serum levels of low-density lipoprotein (LDL) cholesterol, triglycerides, and high-density lipoprotein (HDL) cholesterol. According to both the American Diabetes Association and the National Cholesterol Education Program (NCEP), the primary target of therapy is the serum LDL cholesterol level, with the secondary targets being non-HDL cholesterol, triglycerides, and HDL cholesterol. The recently updated guidelines of the NCEP place new emphasis on increasing soluble fiber intake to 10 to 25 g/d and adding foods fortified with plant stanols/sterols (2 g/d) as options to enhance the LDL cholesterol-lowering effect of diet.
