中文摘要:

      膳食纤维是一种多糖, 它既不能被胃肠道消化吸收, 也不能产生能量, 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。本文从膳食纤维的定义与分类出发, 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, 以期为膳食纤维在胃肠道营养健康方面的研究及相关产品开发提供理论基础。

英文摘要:

      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.
