Summary:
- The study found that the artificial sweetener erythritol can cross the blood-brain barrier, which is the protective layer that regulates what substances can enter the brain.
- Erythritol was detected in the brains of participants who consumed the sweetener, suggesting it can accumulate in the brain over time.
- The researchers caution that more research is needed to understand the potential long-term effects of erythritol on brain health, as the impacts of its presence in the brain are still unknown.
