The Scientific Committee for Food of the European Union conducted an assessment that determined maltitol is a safe food additive. Additionally, the U.S. Food and Drug Administration granted maltitol a “Generally Recognized As Safe” status. Maltitol is non-toxic and does not promote cancer, although consuming it can produce side effects.
There is no daily intake limit for maltitol as of 2015; however, consuming high levels of maltitol can cause intestinal gas, cramping and diarrhea. It can also cause an allergic reaction in sensitive individuals. Maltitol has a relatively high glycemic index value and is not as sweet as sugar, potentially causing a person to use more of it to receive the same effect as if using sugar.
