Rice with double mutation of starch synthase IIIa and branching enzyme IIb (ss3a/be2b) has much higher amounts of apparent amylose and resistant starch (RS) than usual varieties. In this study, we conducted two randomized, single-blind, crossover trials to investigate the effect of single ingestion of two processed foods composed of ss3a/be2b mutant rice on postprandial blood glucose and insulin response in healthy adults, compared to those of usual cultivar. In trial 1, of ingestion of rice crackers, the incremental area under the curves of glucose (IAUCglc) and insulin (IAUCins) in RS group was significantly lower than in the control group. In trial 2, of the ingestion of cooked rice, IAUCglc in the RS group was significantly lower than in the control group. These results showed that the ss3a/be2b-mutant rice cracker and cooked rice having high RS can attenuate postprandial blood glucose and insulin response.

一次摄入饼干和高抗性米饭对健康成年人的餐后葡萄糖和胰岛素反应的影响：两项随机，单盲，交叉试验。

淀粉合酶IIIa和支化酶IIb（ss3a / be2b）双重突变的水稻比常规品种具有更高的表观直链淀粉和抗性淀粉（RS）。在这项研究中，我们进行了两项随机，单盲，交叉试验，以研究与正常品种相比，一次摄入两种由ss3a / be2b突变稻组成的加工食品对健康成年人餐后血糖和胰岛素反应的影响。 。在试验1中，食用米果，RS组的葡萄糖（IAUCglc）和胰岛素（IAUCins）曲线下的增加面积显着低于对照组。在试验2中，在食用米饭中，RS组的IAUCglc显着低于对照组。
