People think this is healthy, but it was just linked to increased risk of heart attack, stroke, and death

Xylitol, a popular sugar substitute and naturally occurring alcohol, has gained popularity as a health-conscious alternative to conventional artificial sweeteners. Frequently found in sugar-free sodas, foods, and oral hygiene products, xylitol is marketed for its zero sugar, low-calorie properties and minimal impact on blood sugar. However, a recent study from the European Society of Cardiology has revealed a potential link between xylitol consumption and increased cardiovascular risk.

Researchers in Germany analyzed data from two large, long-term population studies, comprising 17,710 participants. After tracking these individuals for six years, the study found that those with the highest levels of xylitol in their blood experienced a 57% higher risk of adverse cardiovascular events, such as myocardial infarction, stroke, or death, compared to those with lower levels.

The lead author of the study, Dr. Marco Witkowski, a cardiologist at Charité University Hospital in Berlin, explained that prior research has shown that xylitol can enhance platelet clot formation. In a previous three-year study, high blood levels of xylitol were linked to cardiovascular events in high-risk individuals. This new six-year study aimed to determine if xylitol increases cardiovascular events in a broader general population over an extended period.

Despite its increasing use in a wide range of products, the study concludes that the long-term impact of xylitol on heart health remains unclear.
