Postprandial glucose, insulin, and incretin responses to grain products in healthy subjects.

Background: Various botanical and structural characteristics of starchy food modify the postprandial glucose and insulin responses in humans.

Objective: We investigated what factors in grain products affect human glucose and insulin responses and elucidated the mediating mechanisms.

Design: Ten men and 10 women [mean age: 28 +/- 1 y; mean body mass index (in kg/m(2)): 22.
