Xylitol was not included in the study. Because xylitol is absorbed more slowly from the gut and gut microflora appear to be the mechanism of action found in this study, I'd personally be at least a little concerned.

Mice in this study were given sweeteners for 11 weeks, long enough that their use apparently led to changes in microflora which were associated with glucose intolerance. Existing studies of xylitol could well be for much shorter lengths of time and might not have been able to detect these kinds of changes.

I wonder then if its the absorption of the gut or if it is the conditioning. If the gut flora have to adapt to trying to break down an impenetrable compound they might become super strong at breaking down simpler molecules no?
