The consumption of 25 g of available carbohydrates from black bean attenuates serum glucose and postprandial insulin peaks. After consumption of 25 g of glucose or 25 g of available carbohydrates from black bean, blood samples were taken at different times over 2 h. (A) Serum glucose, (B) serum insulin, (C) total plasma GIP and (D) total serum GLP-1 in eight healthy subjects. For each graph, the area under the curve (AUC) was calculated and showed as an inset in each panel. Data are shown as mean ± SEM. Significant differences were considered with p < 0.005.
