Named a popular sugar substitute that can lead to stroke

Scientists from the University of Colorado have discovered a potential health threat associated with erythritol - a widespread sugar substitute that is actively used in products positioned as a "healthy alternative". The results of the study were published in the authoritative scientific journal Journal of Applied Physiology (JAP).

Laboratory tests revealed the alarming ability of this substance to disrupt the normal functioning of blood vessels in the brain and increase the likelihood of dangerous blood clots forming.

During the experiments, brain vessel cells were exposed to erythritol at a concentration equivalent to one sweetened beverage. The results were concerning: oxidative stress increased by 75%, production of nitric oxide, necessary for vessel dilation, decreased by 20%. Simultaneously, the production of substances that cause vessel constriction increased by 30%, and the mechanism of natural clot dissolution was disrupted.

"The combination of these changes creates the perfect environment for stroke development," warns Auburn Berry, the research team leader.

Erythritol is currently a key ingredient in many products designed for people with diabetes and followers of the keto diet. It can be found in chewing gums, soft drinks, and desserts labeled "sugar-free".

The researchers note that the experiments were conducted exclusively on cell cultures, not on living organisms. For a complete understanding of the risks, further research is needed to determine the effects of various doses on the body, the long-term consequences of regular consumption, and to identify potential high-risk groups.
