xylitol
A polyol with a real (if low-certainty) dental niche and the same emerging, single-lab cardiovascular-thrombosis question as erythritol.
2 well-supported · 0 disputed. This shows how settled each sub-question is, not whether xylitol is "good." Direction lives in each claim below.
The 5 claims about xylitol
Each keeps its own verdict — we never average them away.
Does xylitol raise your risk of heart attack and stroke?
Strong support An early signal resting on very little evidence — a handful of observational studies from a small number of research groups, closely related to the erythritol work. Nobody has run a trial. Worth watching, far too thin to act on.
xylitol does not raise blood glucose
Strong support
Does xylitol prevent ear infections in children?
Insufficient Modest evidence that it reduces recurrent ear infections in children — but the effect depends on frequent dosing through the day, which is hard to keep up in real life, and the studies come from only a couple of research groups. Promising, not proven.
xylitol causes gastrointestinal symptoms
Insufficient
xylitol prevents dental caries
