食药同源植物膳食纤维的化学成分和肠道菌群调节作用研究进展

Research Progress on the Chemical Composition and Intestinal Flora Regulation of Dietary Fiber from the Edible and Medicinal Plants

摘要: 膳食纤维作为一种新型营养素，可以通过调节肠道菌群结构在机体免疫、代谢等方面发挥重要作用。食药同源植物膳食纤维（Edible and medicinal dietary fiber，EMDF）同时兼具了中草药强身健体和膳食纤维促进肠道健康的双重作用，这使其具有不同于普通膳食纤维的性质特点。本文对EMDF研究进展进行总结，针对其化学组成、分布特点及肠道作用进行分析，重点就EMDF对肠道菌群结构的影响及其肠道作用机制进行综述，本研究为EMDF在功能性食品中的开发和利用提供了理论依据。

Abstract: As a new nutrient, dietary fiber can play an important role in immunity and metabolism by regulating the structure of intestinal microflora. Edible and medicinal dietary fiber (EMDF) has the dual functions of strengthening the body with Chinese herbal medicine and promoting intestinal health with dietary fiber, which makes it different from ordinary dietary fiber. This paper summarizes the research progress of EMDF, analyzes its chemical composition, distribution characteristics and intestinal function, and focuses on the effect of EMDF on intestinal microflora structure and its action mechanism. This study would provide a theoretical basis for the development and utilization of EMDF in functional foods.
