It’s quite common to find isomalt used as a sugar substitute, particularly in sugar free or dietetic foods. 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.
This does not mean that isomalt can’t create problems, especially when consumed in large quantities. Studies on people taking isomalt have linked the substance to a high rate of stomach upset, gas and diarrhea. Even in relatively low doses, isomalt can cause diarrhea in about 10% of women who take it and about 4% of men. Just as with sugar, it’s a good idea to keep consumption of isomalt to a minimal amount, more so for the stomach upset it may cause than because of any long-term negative effects.
