摘　　要：肠道内的微生物在为肠粘膜细胞提供营养中扮演着重要角色。若肠道微生态系统的平衡被破坏 ,可导致肠道的屏障功能减弱 ,从而引起疾病。膳食纤维可分为不可溶性纤维和可溶性纤维。不可溶性纤维在增加粪便体积与预防便秘中起着重要作用。结肠与可溶性纤维酵解的副产品之间能相互作用 ,从而得到维持细胞生长与功能所需的营养物质。The microflora plays an important role in providing nutrients to the intestinal mucosal cells.The disruption of the intestinal microflora balance may modify the intestinal barrier function, and influence the health.Dietary fibre can be divided into solububle fibre and insoluable fibre.Insoluable fibre plays an important role in faecal bulking and prevention of constipation.The human body can obtain energy for growth and maintenance of cellular function from fermentation of solable fibre.
