"No serious health risk exists in most humans for normal levels of consumption. The European Food Safety Authority has not set a limit on daily intake of xylitol. Due to the adverse laxative effect that all polyols have on the digestive system in high doses, xylitol is banned from soft drinks in the European Union. Similarly due to a 1985 report, by the E.U. Scientific Committee on Food, stating that "ingesting 50 g a day of xylitol can cause diarrhea", tabletop sweeteners, as well as other products containing xylitol are required to display the warning: "Excessive consumption may induce laxative effects"
Xylitol gum exists in the EU too. It would almost certainly be banned if consuming even a slightly high amount of gum was linked to health risks.

It's not a lack of regulation problem.
