Study links high blood xylitol levels to cardiovascular risks

A study presented at the ESC Congress 2026 found that individuals with the highest blood xylitol levels faced higher risks of major cardiovascular events over follow-up periods.

Cardiologist Dr Punya Pratap Kujur noted that the study was observational and blood xylitol levels do not directly measure individual consumption since the body produces xylitol naturally.

Experts cautioned against panic or altering dietary guidelines immediately, emphasizing that overall diet and proven heart health measures remain paramount.
