Xylitol, also known as “birch sugar”, is a sugar substitute that has become increasingly popular in recent years. And rightly so, as xylitol has a wide range of positive properties, especially in comparison to cane and beet sugar. It has an anti-cariogenic effect and is therefore particularly recommended for people who are prone to tooth decay. It promotes the incorporation of calcium into tooth enamel and increases calcium absorption in the intestine.
