Xylitol is a type of naturally-occurring alcohol that is used as a sweetener.

What are the health benefits of xyitol?

Xylitol granules are a popular sugar replacement used in beverages and baking. It’s also used in chewing gums, toothpaste and medicines.

While xylitol has a sweetness that is equivalent to sugar, it only has two-thirds of the kilojoules. Besides being lower in kilojoules than sugar, making it attractive to those on a weight-loss regime, xylitol also has the following health benefits:

  • Dental benefits, such as preventing tooth decay and lowering the formation of cavities.
  • Assisting in the management of blood sugar levels in those affected by diabetes, as it is absorbed slower than sugar.
  • In some cases, xylitol may assist in preventing the occurence of acute middle ear infections in pre-school children.
