Erythritol is a widely used low-calorie sweetener in “sugar-free” or “keto” soft drinks, baked goods, and candies. In lab experiments, it promoted release of a blood vessel-constricting compound, and impaired release of a key clot-busting protein. These are all associated with higher risk of stroke.
