Resistant Wheat Starch Lowers Glycemic and Insulin Response


Jan 12, 2010

Fibersym RW, a resistant wheat starch belonging to the RS4 classification and produced by MGP Ingredients, Inc., is effective in developing food products with a lower glycemic and insulin response based on a study published on-line in the Journal of Nutrition and Metabolism.

Using the standard glycemic index protocol and performed by Kansas State University (KSU), Manhattan, the study involved 13 healthy adults who were fed two nutritional bars, as well as a control glucose drink, after a 12-hour overnight fast. Puffed wheat was formulated in a bar and Fibersym® RW was incorporated in a second nutritional bar by totally replacing puffed wheat in the formula while all the other ingredients were kept identical. The two bar samples and the glucose drink each delivered 50 grams of available carbohydrates. Blood glucose and insulin levels were monitored over a two-hour period after the samples were consumed.
