The baby step is very significant to me. Because if the study did not account for other factors known to correlate or actively contribute to strokes and death by heart attack then it would be pretty weak and easily dismissed as correlation is not causation. If the findings are true that, there is a correlation between xylitol ingestion and strokes and death by heart attack outside of any other known factors, then it immediately calls for action. Foremost for those who consume xylitol to consider cutting back or abstaining until further research can be done. In addition it provides focused motivation for some postmortem analysis for xylitol and testing on what mechanism might cause the increased risk.
But I do personally have skin in the game as I enjoy chewing xylitol gum. I find it to be an enjoyable treat that I considered guilt free in terms of no calories from sugar, and even better perhaps killing cavity causing bacteria that would be fed by sugar, all while giving my mouth a cool clean mint freshness. So it is a bummer to find that those benefits may have a very negative side effect in the long run.
I hope your skepticism is true, and some researches are trying to hide behind a weaselly association; but hopefully the scientific process will play out with another party or two conducting similar studies and research while others further the research and starting cutting people looking for xylitol in the veins!
