Acacia gum, also called gum arabic, is a dietary fiber, i.e. a substance that is not degraded in the stomach or small intestine. As it enters the colon undigested, in can exert beneficial prebiotic effects. One such effect is lowering of plasma glucose and insulin levels following a meal intake.
A double-blind, controlled, randomized, three-way cross-over study substantiating this effect was successfully conducted at a&r’s clinical trial center. 36 healthy but overweight men and women were enrolled. Results showed that ingestion of 20 g acacia gum with a meal could statistically significantly lower post-prandial glucose and insulin compared to control, showing that this dietary fiber is able to exert the effect in healthy, i.e. normoglycemic persons.
