title: Interaction of dietary sucrose and fiber on serum lipids in healthy young men fed high carbohydrate diets.
abstract: High sucrose diets may cause increased serum triglycerides and decreased high density lipoprotein concentration. To determine whether dietary fiber protects against these effects, four groups of six healthy young men were assigned to one of four very high carbohydrate diets providing 0, 18, 36, or 52% of calories as sucrose. Each diet was fed in both low (less than 14 g) and high (greater than 34 g) levels of dietary fiber for 10 days each. Triglycerides increased during the 36 and 52% sucrose diets compared to 0 and 18% sucrose diets, and fiber protected partially against this rise. Serum cholesterol and LDL cholesterol were lower during the 0 and 18% sucrose diets than the 36 or 52% sucrose diets but fiber had no effect. HDL cholesterol decreased during all low fat diets, with a trend toward a greater decrease during the high sucrose diets. The results suggest that fiber protects against carbohydrate-induced lipemia but has no effect on cholesterol during very high carbohydrate diets.
