Recent studies suggest that erythritol, a widely used sugar substitute found in many "sugar-free" and keto-friendly products, may be linked to a higher risk of stroke, heart attack, and other cardiovascular events. Researchers found that people with elevated erythritol levels in their blood were more likely to experience serious heart-related issues, potentially due to its effect on blood clotting.
