New research suggests the widely used sweetener erythritol may damage the blood-brain barrier, increasing the risk of stroke and heart attack. A study found erythritol caused oxidative stress and disrupted blood vessel function, hindering the body's ability to regulate blood flow and prevent blood clots. These lab findings align with observational studies linking erythritol consumption to higher cardiovascular disease rates. While erythritol is considered safe by regulatory agencies, the study raises concerns about its long-term effects and the potential trade-offs of using sugar substitutes.
