膳食纤维与肠道微生物及相关疾病的研究进展

肠道微生物与人体长期共生,且与人体健康和疾病密切相关,膳食纤维通过改变肠道微生物的种类与数量,间接影响其在肠道中的代谢产物,进而影响人体的健康与疾病。肠道微生物与膳食纤维密切合作,对人体健康的影响意义重大。本文介绍了膳食纤维的定义、膳食纤维的生理功能、膳食纤维的最适摄入量、肠道微生物及其生理功能、膳食纤维对肠道微生物的影响、膳食纤维及肠道微生物对肥胖、炎症、结直肠癌、妊娠合并症及心脑血管疾病的影响,为通过调整膳食纤维治疗疾病的实践提供参考。

Research progress of dietary fiber and intestinal microorganism and related diseases

Intestinal microorganisms coexist with human body for a long time and are closely related to human health and disease. Dietary fiber affects its metabolites in the intestinal tract by changing the type and quantity of intestinal microorganisms, and then affects human health and disease. The close cooperation between intestinal microorganisms and dietary fiber is of great significance to human health. This paper introduced the definition of dietary fiber, the physiological function of dietary fiber, the optimal intake of dietary fiber, intestinal microorganisms and their physiological functions, the effect of dietary fiber on intestinal microorganisms, reviewed the effects of dietary fiber and intestinal microorganisms on obesity, inflammation, colorectal cancer, pregnancy complications and CCVD, so as to provide reference for the practice of disease treatment by adjusting dietary fiber.
