Maltitol is a natural sugar substitute made by hydrogenation of malt sugar obtained from starch. It has 90% of the sweetness of normal sugar but less calories and does not cause tooth decay. Maltitol is incompletely absorbed into the blood stream which results in a smaller change in blood sugar compared to regular sugar. This is the reason why it is suitable for people with diabetics and on low-carbohydrate diets. Please be aware that excessive consumption of maltitol can cause a laxative effect.

 

Lactitol, also a natural sugar substitute, is derived from the natural milk sugar, lactose, with 40% the sweetness of normal sugar. It is metabolised independently of insulin and therefore suitable for the diabetic diet. Lactitol has a low glycaemic index of 3 with only 2 calories per gram, making it popular for people on low-carbohydrate diets. It will not form dental caries because it is not fermented in the mouth. Lactitol can also be used as an active prebiotic, as studies have shown that it stimulates the growth of gut-friendly bacteria. Please be aware that excessive consumption of lactitol can cause a laxative effect.
