Time courses of blood glucose responses (A), plasma insulin responses (B), and the gastric emptying rate (C) in experiment 2. The subjects consumed a 200-ml drink containing either 20 g of soy protein isolate (protein) or its peptide (peptide) 30 min before the 75-g oral glucose tolerance test, which lasted 120 min. The lines denote individual data in C (n = 9). Mean ± SE. protein vs. peptide, *p < 0.05 and *p = 0.08
