摘要

富含碳水化合物的食物,如白糖或蔗糖,会增加餐后血糖水平,可能会增加患2型糖尿病的风险。有一类化合物越来越受欢迎,因为它在减少糖的释放以吸收到体内的潜在应用是多酚。在一项非随机研究中,研究了在蔗糖中加入不同剂量的富含多酚的甘蔗提取物(PRSE)对降低参与者餐后血糖的影响。四种测试样品的血糖指数(GI)值根据标准化推荐方法,通过比较测试样品的曲线下面积(AUC)与葡萄糖标准计算。四种试验食品的葡萄糖浓度曲线相似。葡萄糖反应曲线和GI值呈剂量依赖性降低。本研究结果表明,prse包被糖可以降低正常人的餐后血糖。此外,GI值随着多酚浓度的增加而降低,表明多酚水平与GI之间存在剂量依赖效应。

Dose-Dependency of the Glycemic Response to Polyphenol-Rich Sugarcane Extract (PRSE)
Foods high in available carbohydrates, such as plain white sugar or sucrose, increase the postprandial blood glucose levels that may aggravate the risk of developing Type 2 Diabetes. One class of compounds that is gaining popularity due to its potential application in reducing the release of sugars for absorption into the body is polyphenols. The study aimed to investigate the effect of adding different doses of polyphenol-rich sugarcane extract (PRSE) to sucrose to lower the postprandial glycemia of the participants in a non-randomized study. The four test samples’ Glycemic Index (GI) values were calculated based on the standardized recommended methodology by comparing the area under the curve (AUC) of the test samples against the glucose standard. The glucose concentration curves were similar for the four test foods. The glucose response curves, and GI values were decreased in a dose-dependent manner. The results of this study indicate that PRSE-coated sugar can lower postprandial glycemia in normal individuals. Additionally, decreasing GI values with an increasing concentration of polyphenols suggests a dose-dependent effect between polyphenol levels and GI.
