膳食纤维（来源于植物的难消化碳水化合物）一词包括一系列不同的化合物，它们对许多重要的胃肠道和全身性身体过程产生不同的影响。肠道的主要作用是在消化后吸收营养。复杂的神经体液通路控制肠道分泌和运动。抑制肠道消化过程的膳食纤维会导致上消化道通过时间减少，这可能会影响饱腹感和饱足感。膳食纤维是这些细菌的主要能量来源，因此显著影响微生物多样性/毒性。膳食纤维还可以直接和间接影响肠道粘膜的先天免疫反应。膳食纤维影响肠道的所有过程，从而可能影响心血管/全身健康。由于许多常用的水胶体是粘性的，可口的膳食纤维，它们有可能用于可接受的食品中，提供广泛的额外健康益处。皇冠版权所有（C）2009由爱思唯尔有限公司出版。保留所有权利。
The term dietary fibre (indigestible carbohydrates of plant origin) encompasses a range of divergent compounds that differentially affect numerous important gastrointestinal and systemic bodily processes.The main role of the gut is to absorb nutrients following digestion. Complex neurohumoral pathways control gut secretion and motility. Dietary fibres that inhibit intestinal digestive processes result in decreased upper GI transit times, which may affect satiety and satiation.The large intestine houses a varied microflora. Dietary fibre is a major energy source for these bacteria, and therefore markedly affects microfloral diversity/toxicity. Dietary fibres can also affect innate immune responses of the gut mucosa both directly and indirectly.Dietary fibre impacts all processes of the gut, which as a result may impact on cardiovascular/systemic health. As many commonly-used hydrocolloids are viscous, palatable dietary fibres, they have the potential to be used in acceptable foodstuffs that offer a wide range of added health benefits.
