How is Xylitol different from other sweeteners?

Xylitol has a very low GI of 7 unlike other natural sweeteners like sugar which has a GI of 64, and honey which has a GI of 62.  Also, unlike artificial and chemically-derived sweeteners such as aspartame and sucralose, Xylitol is 100% natural and is found in some fruits, vegetables and hardwood trees.

Xylitol also differs from other sweeteners such as sorbitol, fructose and glucose because its molecule has five, instead of six, carbon atoms meaning that most bacteria and yeast in the mouth are unable to make use of xylitol, and therefore it is renowned to be beneficial in fighting tooth decay, as opposed to promoting it, like some other sweeteners.  It is also sweeter than some other sweeteners, like sorbitol for example, meaning that it is far more economical as you use much less to achieve a sweet, refreshing taste.
