Postprandial glycemic response is closely associated with gastric emptying rate. However, the effects of combining carbohydrates with liquid on gastric emptying and glycemic response are complicated. Here, we investigated the effect of co-ingesting rice and liquid in different ways on gastric emptying and glycemic response in healthy subjects. We performed a randomized crossover study in 12 healthy females. Three types of test meal were prepared: 150 g white rice (rice), 150 g white rice served alongside 200 mL of green tea (rice + tea), and 150 g white rice with 100 mL green tea poured over and served alongside 100 mL green tea (blend). After eating the test meal, measurements of postprandial glucose were performed, and breath samples for gastric emptying evaluation using (1-
