Interest in the fiber content of foods has decreased in recent years as concerns about fat intake have increased. Fiber, however, remains an important component of the diet. Soluble dietary fiber, including pectic substances and hydrocolloids, is found naturally in foods such as fruits, vegetables, legumes and oat bran. Insoluble fiber, including cellulose and hemicellulose, is found in foods such as whole grains. Fiber supplementation has been used to enhance the fiber content of a variety of foods ranging from cereal-based products to meats, imitation cheeses and sauces. Products used to enhance fiber content of foods have traditionally come from cereals such as wheat, corn and oats. There are a variety of other products, however, such as fruits, vegetables, legumes and less commonly used cereals such as barley, which are potential sources of dietary fiber supplements. This article reviews research on some of these underutilized sources of dietary fiber.
近年来，随着对脂肪摄入量的担忧增加，人们对食物纤维含量的关注度有所下降。然而，纤维仍然是饮食中的重要组成部分。可溶性膳食纤维，包括果胶物质和水胶体，天然存在于水果、蔬菜、豆类和燕麦麸等食物中。不溶性纤维，包括纤维素和半纤维素，存在于全谷物等食物中。纤维补充剂已被用于提高从谷物制品到肉类、仿奶酪和调味汁等各种食物的纤维含量。传统上，用于提高食物纤维含量的产品来自小麦、玉米和燕麦等谷物。然而，还有各种其他产品，如水果、蔬菜、豆类以及较少使用的谷物如大麦，它们都是膳食纤维补充剂的潜在来源。本文综述了对一些未充分利用的膳食纤维来源的研究。
