Resistant maltodextrin is a non-viscous dietary fiber that is fermentable in the colon by colonic bacteria. The objective of this review is to summarize the studies of resistant maltodextrin and its effect on metabolic profile, such as blood glucose, lipid profile, and body weight. Several studies support the idea that resistant maltodextrin may improve blood glucose, insulin sensitivity, lipid profile, and obesity. However, the use of resistant maltodextrin should be limited to minimize the adverse effect on the gastrointestinal system. This review provides information regarding the benefits of resistant maltodextrin on metabolic health as well as its proposed mechanism to enhance the knowledge of this novel fiber. Key teaching points Resistant maltodextrin is a novel non-viscous dietary fiber classified as resistant starch type V that is produced by debranching of the starch structure. Resistant maltodextrin is fermentable in the colon and thus produces short-chain fatty acid. Resistant maltodextrin helps to maintain blood and lipid profiles as well as promote satiety and reducing food intake. High intake of resistant maltodextrin may cause gastrointestinal discomfort due to the gas production and increased osmotic pressure.
抗性麦芽糊精是一种不可消化的膳食纤维,可被结肠中的细菌发酵。本综述的目的是总结抗性麦芽糊精及其对代谢谱(如血糖、血脂和体重)影响的研究。多项研究支持这样的观点,即抗性麦芽糊精可能改善血糖、胰岛素敏感性、血脂和肥胖。然而,应限制抗性麦芽糊精的使用,以最大程度地减少其对胃肠道系统的不良影响。本综述提供了有关抗性麦芽糊精对代谢健康的益处及其增强这种新型纤维知识的作用机制的信息。
主要教学要点
抗性麦芽糊精是一种新型不可消化的膳食纤维,属于抗性淀粉类型 V,由淀粉结构的分支降解产生。抗性麦芽糊精可在结肠中发酵,从而产生短链脂肪酸。抗性麦芽糊精有助于维持血液和血脂谱,促进饱腹感并减少食物摄入。由于产气和渗透压增加,大量摄入抗性麦芽糊精可能会引起胃肠道不适。
