膳食纤维调控胃肠道营养健康研究进展

膳食纤维包括不易消化的碳水化合物和复杂的聚合物木质素,增加膳食纤维的摄入量可以减少胃肠道慢性发病率,该营养物质在食品加工领域和临床研究领域都被广泛应用。本文介绍了膳食纤维的定义及分类,并综述了膳食纤维对人体胃肠道的影响,膳食纤维对肠道微生物的作用及膳食纤维对肠道疾病的影响机制,以为之后膳食纤维在胃肠道营养健康方面的研究及开发提供理论基础。

Research progress of dietary fiber regulating gastrointestinal nutrition and health

Dietary fiber is a kinds of polysaccharide, and it can neither be digested and absorbed by the gastrointestinal tract, nor produce energy. This nutrient is widely used in the field of food processing and clinical research. This paper introduced the definition and classification of dietary fiber, and reviewed the effect of dietary fiber on the human gastrointestinal tract, the effect of dietary fiber on intestinal microbes and the mechanism of dietary fiber on intestinal diseases. It was expected to provide a theoretical basis for the research and development of dietary fiber in the nutrition and health of the gastrointestinal tract.
