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

Key Points:

• A study presented at the European Society of Cardiology Congress 2026 found that higher blood levels of xylitol, a common artificial sweetener, are linked to an increased risk of major cardiovascular events such as stroke and heart attack.
• Researchers analyzed data from over 17,000 participants in two large observational studies, finding that those with the highest xylitol levels had a 57% greater risk of cardiovascular events over six years and an 18% higher risk over 30 years compared to those with the lowest levels.
• The increased cardiovascular risk was dose-dependent and independent of factors like age, sex, body mass index, diabetes, and blood pressure, suggesting a consistent association across different populations.
• Experts caution that while the findings are significant, they are observational and further research is needed; individuals, especially those with diabetes or cardiovascular risk, should consult healthcare providers before making dietary changes.
• The study highlights the need for more investigation into the long-term cardiovascular safety of artificial sweeteners like xylitol as their use in food and dental products continues to grow.
