Erythritol, a popular artificial sweetener found in many keto diet products, has recently come under scrutiny. A study conducted by the Cleveland Clinic has linked erythritol to an increased risk of heart attack and stroke. This research indicates that erythritol can cause blood platelets to become more active, which may lead to the formation of clots. Given its widespread usage, particularly among individuals with obesity, diabetes, or metabolic syndrome, these findings raise significant health concerns. Although the FDA classifies erythritol as “generally recognized as safe,” experts are urging caution and advocating for more comprehensive long-term studies to fully understand its potential health impacts.
