Effect of Tapioca-based FiberSMART® Compared to a Glucose Challenge or Water Control on Postprandial Glycemia in Healthy Subjects: An Acute Randomized Controlled Trial

The goal of this clinical trial is to learn whether a novel tapioca-based soluble fiber, FiberSMART®, affects blood glucose levels after consumption in healthy adult volunteers. The main questions it aims to answer are: Does FiberSMART® raise postprandial (after-meal) blood glucose levels? Is the blood glucose response to FiberSMART® different from that of dextrose or water? Researchers will compare participants' blood glucose responses after consuming 20g of FiberSMART® to their responses after consuming 20g of dextrose or a water control to see if FiberSMART® results in a lower postprandial glucose rise than the dextrose challenge and is no different from the water challenge. Demonstrating the FiberSMART acts like a dietary fiber. Participants will: Visit the clinic on three separate mornings after an overnight fast Consume either 20g of FiberSMART® or 20g of dextrose or a water control Undergo 8 finger-prick blood tests over 2 hours to measure blood glucose levels
