Plant fibers are the portions of plant foods that are not digested in the human small intestine. During this century, remarkable advances have been made in defining the characteristics and importance of most nutrients such as carbohydrate, proteins, fats, vitamins, and minerals. Plant fibers have largely been neglected because they considered to have no nutritive values. In the last decade, however, considerable attention has been focused on the various plant fibers because of their influence on gastrointestinal physiology. Evidence is emerging that plant fibers have profound influences on human nutrition because they alter the absorption and metabolism of many nutrients. We will review the evidence that plant fibers greatly influence the absorption and subsequent metabolism of carbohydrates and fats.
植物纤维是植物性食物中在人体小肠内无法被消化的部分。在本世纪，在明确大多数营养素（如碳水化合物、蛋白质、脂肪、维生素和矿物质）的特性及重要性方面已取得了显著进展。植物纤维在很大程度上一直被忽视，因为它们被认为没有营养价值。然而，在过去十年中，由于其对胃肠生理学的影响，各种植物纤维受到了相当多的关注。越来越多的证据表明，植物纤维对人类营养有深远影响，因为它们会改变许多营养素的吸收和代谢。我们将综述植物纤维对碳水化合物和脂肪的吸收及后续代谢有重大影响的证据。
