Popular Sugar Substitute Linked to Higher Risk of Heart Attack and Stroke

Summary

Category: health A study found that higher blood levels of xylitol, a common artificial sweetener used in sugar-free foods and dental products, are linked to a greater risk of heart attack and stroke. Researchers analyzed health data from over 17,000 people and found that those with the highest xylitol levels had a significantly higher chance of serious heart problems over time compared to those with lower levels.

Key Facts

  • Xylitol is a sugar substitute often added to food, drinks, and oral care products.
  • The study analyzed data from two large groups: the Canadian Longitudinal Study on Aging and the EPIC-Norfolk study.
  • Participants with the highest blood xylitol levels had up to 57% greater risk of major cardiovascular events in one study and 18% greater risk over a longer term in the other.
  • The risk increased as xylitol levels rose, showing a dose-dependent relationship.
  • These findings were independent of common risk factors like age, sex, smoking, diabetes, and high blood pressure.
  • Researchers caution that more studies are needed to confirm the safety of xylitol for heart health.
  • Nutrition experts recommend not changing diets based on this study alone and consulting healthcare providers about artificial sweetener use.
  • The study adds to ongoing research about the effects of artificial sweeteners on health beyond calorie reduction.
