Abstract:

Purpose: To explore the effect of superfine dietary fiber from soybean bran on glucose tolerance in diabetic mice. Methods: Glucose tolerance was determined in common and alloxan-induced diabetic mice fed different granular sizes of superfine dietary fiber (140－200 mesh and more than 200 mesh) at a dosage of 5 g/kg bw each day. Results: Compared with the model group, the areas under the blood sugar curve in common mice treated with superfine dietary fiber at two dosages decreased by 14.94% and 15.48% (P < 0.05), and blood sugar peaks in common mice after meal at two dosages decreased by 12.38% and 12.51%. Similarly, compared with the model group, the areas under the blood sugar curve in diabetic mice treated with superfine dietary fiber at two dosages decreased by 24.05% and 29.68% (P < 0.01), and blood sugar peaks in diabetic mice after meal at two dosages decreased by 38.71% and 39.26%. Conclusion: The blood sugar tolerance in common and diabetic mice treated with superfine dietary fiber has an obvious improvement, and blood sugar peaks and blood sugar levels in common and diabetic mice after meal are significantly decreased. However, the granular size of superfine dietary fiber does not exhibit obvious improving effect on blood sugar tolerance and decrease in blood sugar level.
