In the past 50 years, dietary fiber has become an increasingly significant area of nutritional focus, debate, and research. Advances in food production practices have resulted in more refined foods being available and consumed across the world and particularly in developed nations such as the US. While refined foods are typically more palatable to consumers, the content of dietary fiber is greatly reduced. Currently, many diseases are believed to be associated with a lack of dietary fiber intake and, furthermore, significant health benefits are thought possible via increased consumption of many dietary fibers. There is no well accepted definition for dietary fiber, but most of the references mention the inability of humans to fully digest fibers; most others say about fibers being made of various monomer units of variable length and some mention plant origin. There are many raw materials/ingredients that can increase the fiber content in foods, each with its own set of functional and sensory characteristics, including acacia gum, beta-glucan, cellulose, chitin/chitosan, corn bran, corn fiber, inulin, oat bran/oat fiber, pea fiber, pectin, polydextrose, psyllium, resistant starch, rice bran, soy fibers, wheat bran, and wheat fiber. All these fibers are unique in their functional capability for treatment of number of diseases.
在过去50年里,膳食纤维已成为营养领域中一个日益重要的关注、争论和研究焦点。食品生产方式的进步导致世界各地,尤其是在美国等发达国家,有更多精制食品可供获取和消费。虽然精制食品通常更受消费者欢迎,但膳食纤维的含量却大幅降低。目前,许多疾病被认为与膳食纤维摄入不足有关,此外,人们认为增加多种膳食纤维的摄入量可能会带来显著的健康益处。对于膳食纤维,目前尚无被广泛接受的定义,但大多数参考文献都提到人类无法完全消化纤维;其他大多数文献则称纤维由各种长度可变的单体单元组成,还有一些提到纤维来源于植物。有许多原料/成分可以增加食品中的纤维含量,每种原料/成分都有其自身的一系列功能和感官特性,包括阿拉伯胶、β-葡聚糖、纤维素、几丁质/壳聚糖、玉米麸皮、玉米纤维、菊粉、燕麦麸/燕麦纤维、豌豆纤维、果胶、聚葡萄糖、车前子壳、抗性淀粉、米糠、大豆纤维、小麦麸皮和小麦纤维。所有这些纤维在治疗多种疾病的功能方面都独具特色。
