Erythritol may impair cellular functions essential to maintaining brain blood vessel health, according to researchers at the University of Colorado Boulder. Findings suggest that erythritol increases oxidative stress, disrupts nitric oxide signaling, raises vasoconstrictive peptide production, and diminishes clot-dissolving capacity in human brain microvascular endothelial cells.
The sweetener in question is erythritol. Coke Zero uses aspartame and acesulfame potassium.
Aspartame has shown evidence that it can potentially damage your liver, though.
