中文摘要: 膳食纤维不能被人体的胃肠道消化酶吸收，直接到达大肠，通过发酵作为专性厌氧微生物主要的能量来源。膳食纤维在大肠被发酵产生短链脂肪酸（short chain fatty acids，SCFAs），例如乙酸、丙酸和丁酸等。膳食纤维促进人体健康每日的推荐剂量分别为：成年女人25 g和成年男人38 g。该文系统的介绍膳食纤维的定义和分类，膳食纤维对肠道微生物的作用和膳食纤维对疾病的影响。并且对近几年关于膳食纤维，肠道微生物和相关疾病研究的互作关系进行系统的阐述，同时也对未来膳食纤维-肠道微生物-疾病的研究提出合理化展望，旨在为膳食纤维对肠道菌群和健康的研究提供科学理论参考。
Abstract:Dietary fiber can not be digested by human gastrointestinal digestive enzymes，and can eventually reach large intestine，where it will serve as the main energy source of obligate anaerobic microbiota through fermentation.Dietary fiber in the large intestine will mainly be fermented to produce short chain fatty acids（SCFAs），such as acetate，propionate and butyrate etc.The daily intake amount of dietary fiber is recommended as 25 g and 38 g per day for adult females and males respectively for health promotion.The review systematically represented the definition and classification of dietary fiber，effect of dietary fiber on gut microbiota，and the mechanism of dietary fiber on disease.Overall，the review demonstrated the recent studies on relationships of dietary fiber，gut microbiota，and related disease，and also presented the prospective in the future for dietary fiber-gut microbiota-disease research for providing scientific theoretical reference.
