High dietary fiber(DF) diets lower blood glucose and insulin requirements in diabetics. In this study we evaluated the effects of high dietary fiber(DF) food supplements on glucose metabolism in thirty four subjects with non-insulin-dependent diabetes mellitus(NIDDM). The subjects were divided into three test groups. Each group’s prescribed hospital diets were augmented by one of the three following DF supplements for two weeks: Soybean biscuits containing 5g of total DF-the control group(n=15); Biji biscuits containing 20g of total DF-the high insoluble DF group(n=9); and sea tangle biscuits containing 25g of total DF-the high soluble DF group(n=10). The mean daily DF intake of the subjects during the period were: 19.1±4.3g for the soybean control group; 32.5±4.1g for the Biji group; and 38.1±5.5g for the sea tangle group. The supplementation of the Biji or sea tangle biscuits singnificantly lowered fasting serum glucose levels(p＜0.05) and resulted in the improvement of glucose tolerance. However, the secretions of insulin, C-peptide, and glucagon and HbA_(1c) concentration were not affected by the high fiber supplementary feeding for two weeks. The urinary excretion of glucose decreased remarkably after the addition of the DF supplements in all three groups(p＜0.05). The results indicate that the supplementation of Biji or sea tangle bascuits possesses a beneficial effect on the improvement of glucose metabolism in subjects with NIDDM.
