Re: Xylitol

"shown that SUBSTITUTING XYLITOL FOR SUCROSE in the diet of a human test group during 8 months significantly reduced the number of persons with salivary Candida growth, while there was a slight increase in the test groups receiving sucrose and fructose. At the base line practically every second person had Candida in the saliva." (quote from link, emphasis added)

All it appears to mean is that it is better than sugar. No indication that it's better than no Sugar or Sugar alcohols whatsoever.
