测量膳食纤维的原因有很多。我们实验室有三个目标。首先，对美国食品供应中膳食纤维主要来源的分析将提供一个数据库，可用于临床和流行病学评估个人和人群消耗的膳食纤维的种类和数量。第二，膳食纤维来源的含量和组成与其生理作用有关。例如，近年来迅速积累的证据表明，许多可溶性膳食纤维来源主要在胃肠道的上部具有生理作用，而不溶性来源则影响下肠道的生理学（1）。最终，研究人员希望了解膳食纤维具有特定生理作用的机制;膳食纤维来源的组成及其理化性质将为理解膳食纤维的这些作用机制提供见解。
There are many reasons for measuring dietary fiber. We have three overall aims in our laboratory. First, analysis of the major sources of dietary fiber in the USA food supply would provide a data base of values that could be used clinically and epidemiologically to assess the kinds and amounts of dietary fiber consumed by individuals and populations. Second, the content and composition of dietary fiber sources can be related to their physiological effects. For example, evidence has accumulated rapidly in recent years to suggest many soluble dietary fiber sources have physiological effects primarily in the upper part of the gastrointestinal tract, whereas insoluble sources influence the physiology of the lower gut (1). Ultimately, researchers want to understand the mechanisms by which dietary fiber has a particular physiological effect; the composition of dietary fiber sources, as well as their physiochemical properties, will provide insight into understanding these mechanisms of action for dietary fiber.
