Effect of variations in dietary fat and carbohydrate intake on postprandial lipemia in patients with noninsulin dependent diabetes mellitus.

The effect of dietary composition on concentrations of postprandial lipoproteins was studied in eight sulfonylurea-treated patients with noninsulin dependent diabetes mellitus. Two diets were consumed by each patient for 2 weeks in random order, one contained (as percent of total calories) 15% protein, 40% fat, and 45% carbohydrate (CHO), whereas the other consisted of 15% protein, 25% fat, and 60% CHO. At the end of each dietary period, patients were given Vitamin A (60,000 U/m2) with their noon meal, and the concentration of triglyceride (TG) and retinyl esters in plasma and two lipoprotein fractions (Sf > 400 and Sf 20-400) determined over the next 12 h. The results indicated that both postprandial TG and retinyl ester concentrations were higher in plasma (Sf > 400, and Sf 20-400 lipoproteins), when patients ate the 25% fat/60% CHO diet. Thus, replacing saturated fat with CHO accentuates the magnitude of postprandial lipemia. Since TG-rich lipoproteins may be atherogenic, appropriate dietary advice for patients with type 2 diabetes may deserve reappraisal.
