Study on the effect of fibre enriched milk-drink on insulin and glucose levels

The glycaemic level is dependent on the the quality and content of carbohydrates. Carbohydrates that breaks down quickly during the digestion has a high glycaemic index, or GI; while the one that breaks down slowly has a low GI. People want to have a low GI, since greater extraction from the liver and periphery of the products of carbohydrate digestion. Usually, lower GI also means lower insulin. They are both correlated.
Dairy products have a relatively low carbohydrate content. The high portion from the dairy products is located in the form of lactose, which is responsible for the gastrointestinal symptoms in the population. Because of that, lactose-free dairy products are released. However, the effects of lactose-free products on insulin and glucose metabolism have not been studied. Whether they are healthy or not healthy for human body is an unknown.
A experiment was conducted to measure the insulin and glucose level from 1) a lactose-free milk drink, 2) a novel fibre-enriched, fat- and lactose-free milk drink and 3) normal fat-free milk through a number of people.
The result had shown that the insulin response was significantly lower for the fibre-enriched milk drink than it was for the other milk products. There were no differences in the response for glucose or in the AUC for the subjective satiety ratings between the studied milk products. In conclusion, this novel milk drink could have positive effects on insulin response.
