Erythritol: Sweetness at What Cost? New Study Links Sugar Substitute to Stroke and Brain Damage

Why does this matter? These findings suggest that regular consumption of erythritol, especially in multiple servings per day, could increase the risk of stroke and other cardiovascular issues. Consumers, particularly those with obesity or diabetes who often use erythritol, should be aware of these potential risks.

Erythritol, a sugar alcohol produced by fermenting corn, has become a popular ingredient in sugar-free products due to its low-calorie content and minimal impact on insulin levels. It has been approved by the FDA since 2001.

The new study treated human brain blood vessel cells with erythritol amounts equivalent to a typical sugar-free beverage. The results indicated several adverse changes, including reduced nitric oxide production and increased endothelin-1, leading to constricted blood vessels. The cells' ability to break down clots was also impaired.

While the study was conducted on cells in a lab, the researchers advise caution. Christopher DeSouza, a senior author of the study, encourages consumers to read labels and monitor their intake of non-nutritive sweeteners like erythritol. This research underscores the importance of further studies to fully understand the long-term effects of erythritol consumption on human health.

What is erythritol?

Erythritol is a sugar alcohol used as a sugar substitute in many low-carb and sugar-free products.

What are the potential health risks of erythritol?

Recent studies suggest erythritol may be linked to brain cell damage, increased stroke risk, and other cardiovascular issues.

How much erythritol is considered harmful?

Even small amounts of erythritol, equivalent to a typical sugar-free beverage, have shown adverse effects on brain blood vessel cells in laboratory studies.
