Study Links High Xylitol Levels to Increased Cardiovascular Risk

Researchers presented findings at the European Society of Cardiology Congress in Germany indicating that individuals with the highest blood levels of xylitol faced a significantly greater risk of major adverse cardiovascular events than those with the lowest levels. Over a six-year follow-up, the risk was 57% higher after adjusting for age, sex, smoking, lipid profile, diabetes and hypertension, while a 30-year analysis showed an 18% increase.

The analysis drew on data from 17,710 participants across two prospective observational cohorts. Because the study is observational and has not yet undergone peer review, it cannot establish a causal relationship.

"Our long-term findings in the general population highlight how little we know about the cardiovascular safety of xylitol and indicate that further studies are warranted, especially as the amount of xylitol in products continues to increase," said Dr. Marco Witkowski of Charité University Hospital in Berlin.

"Artificial sweeteners are widely embraced by modern society, and the safety ratings had been good and granted by regulatory authorities. In this observational work, however, it appears that xylitol has a negative long-term effect on cardiovascular events in the general population," noted Dan Atar, professor and member of the ESC Communication Committee.

Both experts emphasized the need for additional research to clarify the potential health implications of xylitol consumption.
