Maltitol is a low-calorie sweetener: 2.1 calories/g

Maltitol does not stimulate insulin secretion: maltitol is difficult to digest and absorb, and the rise in blood glucose value is small, so it does not have a stimulating effect on the secretion of insulin, which is necessary for the metabolism of glucose, and thus reduces the secretion of insulin. Thus, maltitol can be used as a sweetener for diabetic patients.
