Microecology of the gastrointestinal tract is the physiologic basis for the effect of dietary fiber, prebiotics and probiotics on the host. The ecology consists of the gastrointestinal tract, primarily the intestines, the foods that are fed into the tract, and the flora living within. Within this ecology, normal flora and probiotics, ferment dietary fiber and prebiotics to produce short chain fatty acids and substances that are absorbed and effect the host at the intestinal level and systemically. In this review, we will discuss the effects of prebiotics, probiotics and dietary fiber in gastrointestinal disorders and diseases.
胃肠道微生态是膳食纤维、益生元及益生菌作用于宿主的生理基础。这种生态包括胃肠道，主要是肠道，摄入胃肠道的食物以及生活在其中的菌群。在这种生态环境中，正常菌群和益生菌可发酵膳食纤维和益生元，产生短链脂肪酸和可被吸收的物质，这些物质在肠道局部及全身发挥作用影响宿主。在本综述中，我们将讨论益生元、益生菌及膳食纤维在胃肠道疾病中的作用。
