A Randomized, Controlled, Crossover Study to Assess the Glucose and Insulin Excursions of a Test Fiber

The objective of this trial is to evaluate the postprandial glucose and insulin responses to replacing digestible carbohydrates with resistant starch type 4 (RS4) in a baked product in healthy men and women. A randomized, double-blinded cross-over study will be conducted comparing two foods (a reference food and a test food). The primary outcome variable will be the incremental area under the curve (iAUC) for capillary glucose from pre-product consumption (average of t = -15 and -5 min) to 120 min (iAUC0-120 min). This study will provide substantiation for a beneficial reduction in glycemic response followed by the consumption of the active product containing an efficacious dose of resistant starch type 4 (RS4).
