Glycemic, insulinemic, and breath hydrogen responses to pullulan in healthy humans

Abstract The objective of this study was to evaluate the glycemic, insulinemic, and breath hydrogen responses of healthy adult humans to low–molecular weight pullulan (molecular weight = 6300). Subjects (n = 34) consumed 50 g of maltodextrin or low–molecular weight pullulan in a randomized, double-masked, crossover design. Plasma glucose and serum insulin responses were determined over 180 minutes, and breath hydrogen response was determined for 8 hours. Low–molecular weight pullulan did not improve glucose response, but a reduction ( P P P
