How might erythritol increase stroke risk?

A lab study indicated that erythritol may impair clot-busting proteins and cause blood vessels to constrict, potentially contributing to ischemic strokes.

Is there evidence of rising stroke rates?

Yes, the CDC reports a nearly 15 percent increase in strokes among younger adults since 2011, a trend that has heightened concerns about sweeteners.

Sugar-Free Sweetener Linked to Stroke Risk

Recent research indicates that erythritol, a common sugar substitute found in sugar-free energy drinks, ice creams, and protein bars, may elevate the risk of life-threatening strokes. A study conducted at the University of Colorado exposed human cells to erythritol, mimicking levels found in diet sodas.

Analysis revealed significant adverse effects on cells from the blood-brain barrier and blood vessels within three hours. The sweetener appeared to reduce the release of crucial clot-busting proteins and caused dangerous constriction of blood vessels. These findings suggest a potential contribution to ischemic strokes, which occur when blood clots block brain arteries.

These concerns are amplified by a nearly 15 percent surge in strokes among younger adults since 2011, according to the CDC. While the study had limitations, being conducted on isolated cells, it adds to a growing body of evidence raising questions about the long-term impact of sweeteners on vascular health. Consumers are advised to be mindful of their daily erythritol intake.
