Abstract

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.
