Figure 2. Postprandial change in blood parameters after consumption of test beverages. Blood (A) glucose, (B) peak blood glucose clearance, (C) insulin, and (D) active GLP-1 after consumption of the placebo (closed circles), control (CPE with HHQ, closed squares), and active (CPE without HHQ, open squares) beverages. Data are expressed as means ± SEM; n = 10 in each group. Two-way repeated ANOVA was used to compare changes over time and between the groups. Asterisks indicate the probability level of random differences between groups: **, P < 0.01 significantly different from the placebo group (ANOVA with Bonferroni post hoc test); ##, P < 0.01 significantly different from the control group. (A, C, D inset) Incremental area under the curve (iAUC) or decremental AUC (dAUC) of each blood variable for 2 hours after the meal plus test beverage ingestion. N.S., not significant (P > 0.05) among the groups (Bonferroni post hoc test). (B), Peak blood glucose clearance was calculated as Δglucose (30-60 min)
