Study Raises Questions About Zero-Calorie Sweetener Erythritol

A recently released peer-reviewed study from the University of Colorado Boulder has raised questions about the vascular safety of erythritol, a zero-calorie sweetener found in many diet beverages and low-carb foods.

The research, published in the Journal of Applied Physiology, tested erythritol's effects on human brain microvascular endothelial cells — key regulators of cerebral blood flow and the blood-brain barrier.
