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.
When on Earth did that become major?
It’s mixed with other artificial sweeteners (I know of at least the monk fruit in my pantry) to get better weight to sweetness ratios. Most of the most popular artificial sweeteners are far stronger, sometimes hundreds of times stronger, than sugar. So they mix them with erythritol, which is less sweet than sugar, so you can replace 5g of sugar with 5g of the artificial sweetener in recipes and get the right sweetness.
It’s a common sweetener in keto foods.
