被看作是无营养价值的植物纤维,过去从未受到重视;近10年来的研究证明,植物纤维对于许多营养物质的消化、吸收和代谢起着重要作用。大部分植物纤维是植物细胞壁的组成部分,是不被人类消化酶所消化的多糖类,在小肠中不被消化,多数可在结肠消化或酵解。现已确定有几百种不同的纤维分子,它们通常含有各种己糖和戊糖。

It has been regarded as a non-nutritive plant fiber and has never been valued in the past. Studies in the past 10 years have proved that plant fiber plays an important role in the digestion, absorption and metabolism of many nutrients. Most plant fibers are part of plant cell walls and are not digested by human digestive enzymes. They are not digested in the small intestine and most can be digested or digested in the colon. Hundreds of different fiber molecules have now been identified, often containing various hexoses and pentoses.
