Fiber-Milk Drink Lowers Insulin Response

STILLWATER Okla.A novel fiber-enriched, fat- and lactose-free milk drink may have positive effects on insulin response, according to a study published in Nutrition Journal (2009;8:43). Researchers investigated the effects of 1) a lactose-free milk drink, 2) a novel fiber-enriched, fat- and lactose-free milk drink and 3) a normal fat-free milk on serum glucose and insulin levels and satiety using a randomized block design. Following an overnight fast, 26 healthy volunteers ingested 200 ml of one of these drinks on three non-consecutive days.

The insulin response was significantly lower for the fiber-enriched milk drink than it was for the other milk products (AUC; P=0.007). There were no differences in the response for glucose or in the AUC for the subjective satiety ratings between the studied milk products.
