Unlike regular sucrose, isomalt does not tend to raise blood glucose levels and is considered safe for consumption by diabetics. Animal studies with suggest the product is not carcinogenic or toxic.
Isomalt is not completely without calories. It contains roughly half the calories of sugar. That’s about eight calories per teaspoon. So though it will lower calorie intake, it can't be used in zero calorie sodas. On the plus side, it won’t degrade your teeth, as does regular sucrose.

den har GI på 2, og det er supert, men da den søter halvparten av det sukker gjør og inneholder halvparten av kaloriene vil det blir like mange kalorier og karbo som vanlig sukker i produktet. Så få som du spiser ville jeg fortsatt med det pga den lave GI.

står det noe litt annerledes--Isomalt is not efficiently absorbed by the body, and it is only partly metabolized. Its caloric value depends on several factors, as discussed in my essay "Polyols and Calories." In the USA, isomalt provides 2 calories per gram for labeling purposes. In the European Union, it is listed at 2.4 calories per gram. t iis about 40% as sweet as sucrose, on a weight basis.

står det mer :The human body uses about 50% of isomalt because it belongs to a fibre group known as "low digestible carbohydrates".
