Xylitol has less intensive impact on the insulin system and does not cause a glycaemic peak as strong as you experience it with sugar.
Xylitol is also proven to directly prevent Caries.
There are numerous studies on Xylitol and its benefits - Google is your friend.
How is it possible that in a thread on sugar even after 146 comments nobody mentions Xylitol?
BTW ... Xylitol is for me not a sugar-subtitute because it tastes better than sugar.
