Several effects of dietary fibre on colonic function have been documented by experiment or deduced from epidemiologic observation. The magnitude of these changes depends on the source and the physical and chemical composition of the fibre used, and on the individual response of the subjects. Three theories of the mode of action of fibre are discussed; they relate to the water-holding capacity of fibre, the production of short-chain fatty acids from fibre in the colon and the alteration by fibre of the colonic microflora.
膳食纤维对结肠功能的多种影响已通过实验得到证实，或从流行病学观察中推导得出。这些变化的程度取决于所用纤维的来源、物理和化学组成，以及受试者的个体反应。文中讨论了纤维作用模式的三种理论；它们分别与纤维的持水能力、结肠中纤维产生短链脂肪酸以及纤维对结肠微生物群的改变有关。
