Insoluble Fiber in Young Barley Leaf Suppresses the Increment of Postprandial Blood Glucose Level by Increasing the Digesta Viscosity

Figure 3

Oral sucrose tolerance test with the water-EtOH soluble and insoluble fractions of BLP. The delta blood glucose levels in rats at 0–120 minutes after oral administration of 2,000 mg/kg of sucrose with no BLP (control), 1,500 mg/kg of BLP, 384 mg/kg of the soluble fraction, and 1,100 mg/kg of the insoluble fraction were measured. Each data point represents mean ± SEM, for 𝑛=14 (control, BLP, and soluble fraction) and 𝑛=13 (insoluble fraction). A significant interaction was found between the effects of the different fractions and the time after administration (𝑃<0.001, 2-way ANOVA). Delta blood glucose levels without a common letter differ (𝑃<0.05, multiple comparisons).
