Slowly digested carbohydrate foods elicit lower postprandial glucose and insulin responses than foods with more readily digestible dietary carbohydrate. Because of the health benefits of lower postprandial glycemic response, they are often desired by consumers.

New research from GI Labs sought to determine the postprandial glucose and insulin responses after consumption of a savory cluster snack containing nuts, whole grains and soluble fiber, produced using a novel process that controlled moisture and temperature in order to reduce the rate of carbohydrate digestion.

Using a randomized crossover design, 25 participants were studied on three occasions after consuming the test food, a control cluster, or a  portion of white bread matched for available carbohydrate content. The participants provided blood samples over a period of 4 hours. 

The test cluster elicited lower postprandial glucose and insulin responses than the control cluster, demonstrating that the cluster is digested and absorbed more slowly.

“When using novel ingredients or new production methods to create novel foods, it is crucial to conduct a clinical trial to demonstrate whether the food product does indeed behave as hypothesized. At GI Labs, we are proud to provide a complete spectrum of clinical research services to support our clients’ product development efforts,” says Dr. Thomas Wolever, President of GI Labs.
