Story summary

Researchers at the University of Colorado warn that erythritol may damage the blood-brain barrier and raise the risk of heart attacks and strokes.
The study finds erythritol disrupts blood vessel regulation by reducing nitric oxide and increasing endothelin-1, potentially causing ischaemic strokes.
Observational studies link high erythritol levels to cardiovascular risk, while regulators deem the sweetener safe despite this new evidence.
