This study was designed to test the laxative effects of two fibers a resistant starch made from corn and a glucose polymer fiber. The secondary aim of this study was to examine the satieting effects of these fibers. This trial was double-blind and placebo controlled. On the first day of the study subjects consumed the breakfast cereal and milk and were instructed to complete visual analog scales periodically to test acute satiety. Subjects also completed diet records and tolerance questionnaires on days 1,2, and 10. Additionally subjects completed another satiety survey on day 10 to test chronic satiety. Whole gut transit time, fecal weight, and fecal chemistry was tested by swallowing radioopaque pellets on day 6 and collecting every fecal sample for the 5 days thereafter.
