A new study from the University of Colorado Boulder has raised concerns about the potential health risks associated with erythritol, a popular sugar substitute. Researchers found that even short-term exposure to high levels of erythritol can damage brain vessel cells, leading to an increased risk of stroke.
The study, led by Professor Christopher DeSouza, exposed human brain vessel cells to a typical drink-size dose of erythritol for just three hours. The results showed that the cells became stressed, producing more free radicals and decreasing nitric oxide production. This can lead to constricted blood vessels, which can increase the risk of stroke.
The researchers also found that erythritol increased the production of endothelin-1, a protein that signals blood vessels to tighten up. This combination of effects can have serious consequences for cardiovascular health.
While the study was not designed to track long-term effects, it raises concerns about the potential risks associated with consuming high amounts of erythritol regularly. The researchers are calling for people to monitor their consumption and consider reducing their intake.
The findings of this study add to growing evidence that non-nutritive sweeteners may have negative health consequences, despite being marketed as safe alternatives to sugar. As more research becomes available, it is essential to be aware of the potential risks associated with these substances.
