“…Potter et al [20] assessed the effect of dietary fiber on the glucose response to 3 different diets of varying fiber content (18, 16.2 and 2.8 g) but identical protein, fat and carbohydrate content fed to 8 healthy men aged 22 to 45 years. They found that the lowest glucose response occurred in the group with a dietary fiber intake of 18 g per day and the highest occurred in the group with 2.8 g of dietary fiber per day.…”

Background/Aim: While it has been demonstrated that rice bran might lower the cholesterol level in hypercholesterolemic individuals, its effects on the levels of adiponectin and glycated hemoglobin (HbA1c) in patients with type 2 diabetes mellitus remain unknown. Methods: Twenty-eight volunteers with type 2 diabetes were randomly divided into 2 groups, one of which received a dietary supplement of 20 g of stabilized rice bran and the other placebo once daily for 12 weeks. Parameters such as the level of HbA1c, glucose, insulin, homeostasis model assessment for estimation of relative insulin resistance, high-density and low-density lipoprotein (LDL) cholesterol and adiponectin were evaluated. Results: At the end of the study period, postprandial glucose and the area under the glucose curve of the rice bran group were significantly lower than baseline levels by 14.4 and 15.7%, respectively. Compared to baseline, the HbA1c values in the rice bran group were also significantly lower. Serum total cholesterol and LDL cholesterol concentrations in the rice bran group were 9.2 and 13.7% lower, respectively, than in the placebo group. The plasma free fatty acid and adiponectin concentrations were 20% lower and 40% higher in the rice bran group compared to the placebo group. Conclusions: This study demonstrated that stabilized rice bran can lower the level of HbA1c and blood lipids and increase blood adiponectin concentrations in type 2 diabetic subjects. In light of this, we conclude that stabilized rice bran may represent an important functional nutrient to ameliorate lipid and glycemic anomalies in type 2 diabetic subjects.

“…A large number of clinical investigations after the mid-1970 s reported the effects of dietary fibre on metabolic responses in normal and diabetic subjects [39,[40][41][42][43][44][45][46][47]. Among randomized crossover studies of high and low fibre intake in natural food form and administered under isocaloric conditions, the most consistent finding has been an inverse association between fibre intake and postprandial insulin concentrations.…”

Background: Fiber regulates the rate and site of lipid and carbohydrate digestion and absorption and thus can modify the alimentary responses to a meal. When fiber sources containing viscous polysaccharides are included in a meal, a slower rate of carbohydrate and lipid absorption will modify the alimentary hormone and lipid responses. Objective: We investigated in 11 healthy men the response of insulin, glucose, cholecystokinin, and lipid to 2 test meals containing ␤-glucan. Design: One of the meals was high in fiber (15.7 g) and the other meal was low in fiber (5.0 g). The low-fiber meal contained pasta made with wheat flour. The high-fiber meals contained pasta prepared by replacing 40% of the wheat with 2 types of barley flour: barley naturally high in ␤-glucan and the other a flour enriched in ␤-glucan during processing. Results: Plasma glucose and insulin concentrations increased significantly after all meals but the insulin response was more blunted after the barley-containing meals. The test meals were low in fat (25% of energy) but elicited an increase in plasma triacylglycerol and cholecystokinin. Cholecystokinin remained elevated for a longer time after the barley-containing meals. After the low-fiber meal, plasma cholesterol concentrations did not change significantly; however, 4 h after the barley-containing meals, the cholesterol concentration dropped below the fasting concentration and was significantly lower than that after the lowfiber meal. Conclusions: Carbohydrate was more slowly absorbed from the 2 high-fiber meals. Consumption of the barley-containing meals appeared to stimulate reverse cholesterol transport, which may contribute to the cholesterol-lowering ability of barley.Am J Clin Nutr 1999;69:55-63.
