Artificial Sweetener Xylitol Associated with Higher Risk of Adverse Cardiovascular Events

Researchers found a dose-dependent link, with the highest xylitol blood levels tied to a 57% greater six-year risk of major cardiovascular events.

  • On Saturday in Munich, researchers presented a study at the European Society of Cardiology annual congress linking high blood xylitol levels to a 57% higher risk of major cardiovascular events over six years in 17,710 participants.
  • Charite University Hospital cardiologist Dr. Marco Witkowski led the analysis of two long-running cohorts, building on a 2024 study that associated xylitol with increased platelet reactivity and clotting potential.
  • Findings from the EPIC-Norfolk cohort revealed an 18% higher risk of major cardiovascular events over a 30-year span, with data suggesting a dose-dependent relationship where higher xylitol blood levels correlate with greater cardiovascular event rates.
  • Professor Dan Atar of the ESC Communication Committee cautioned that the observational study does not prove xylitol consumption directly causes heart attacks or strokes, warranting further investigation despite the apparent negative long-term effect.
  • Xylitol is commonly added to foods, beverages and chewing gum at levels over 1,000 times higher than naturally occurring amounts, yet experts emphasize that 'sugar-free' labels do not guarantee products are free of long-term cardiovascular consequences.
