You may have heard the name Xylitol thrown about lately, mostly as an ingredient in natural toothpaste and chewing gum but are you still wondering what it actually is and what’s so great about it?

Allow me to explain..



In a nutshell, Xylitol is a natural sweetener extracted from the Birch tree.

Birch Tree

It surprised me to learn it is also used as a medicine to prevent middle ear infections in children as well as a dental aid to neutralise food acid after eating.



Xylitol is available in powder form, just like sugar (but has 40% less calories) as well as being an ingredient in gums, pastilles and lozenges. Many dentists recommend the use of Xylitol gum or mints. My sister who is visiting from Europe at the moment works in childcare/education and tells me in Scandinavia all the children take Xylitol ‘tablets’ after each meal to neutralise acid in Saliva in order to prevent tooth decay. It is common practice for all the children to have their own supply, and in instances that they don’t the child care centre provides it. This knowledge blew me away and prompted me to research as I had never heard of such a practice here in Australia!

Xylitol is also used as an excellent replacement for sugar with good reason! It’s glycemic index is 7 (sugar has a GI of 60-70, yes really!).

Xylitol also helps the digestive system absorb Calcium AND helps to fight the yeast Candida Albicans.




In my mind I think it’s only a good thing and something we absolutely should be doing here, mainly as a proactive measure against tooth decay and gum problems.
