Key Findings:
Increased Platelet Activity: The study showed that erythritol promotes platelet aggregation, making it easier for blood clots to form. While clotting is a normal bodily process crucial for stopping bleeding, excessive clotting can obstruct blood flow in critical areas, like the heart and brain, leading to potentially life-threatening conditions.
Elevated Cardiovascular Risk: Participants with high blood erythritol levels were at significantly higher risk of experiencing heart attacks or strokes, especially if they already had underlying cardiovascular conditions. The risk was particularly pronounced among those with preexisting conditions like diabetes, hypertension, and obesity, all of whom are more likely to consume sugar substitutes in efforts to manage their health.
Rapid and Sustained Blood Levels of Erythritol: When volunteers were given beverages containing erythritol, their blood levels of the sweetener increased dramatically and remained elevated for several hours, suggesting that regular consumption could lead to a prolonged state of heightened cardiovascular risk.
Implications for Consumers
These findings raise critical questions about the safety of erythritol, especially for people who are already at risk for cardiovascular disease. The study authors emphasized that while erythritol has long been considered safe due to its low-calorie profile and minimal impact on blood sugar, its effects on cardiovascular health have not been sufficiently examined until now.
For consumers, especially those with a history of heart disease or other cardiovascular risk factors, this study calls for a reevaluation of erythritol’s role in their diet. As it is commonly found in products marketed as “healthier” alternatives to sugar, many individuals may be unknowingly increasing their risk of clotting-related complications.
The Broader Context: Sweeteners and Health
Artificial sweeteners have long been promoted as healthier alternatives to sugar, particularly for individuals with diabetes or those seeking weight loss. Erythritol, in particular, has been favored due to its minimal caloric content and low glycemic index, which means it does not spike blood sugar levels as dramatically as sugar does. However, the assumption that “zero-calorie” automatically means “safe” is now being challenged.
This new research on erythritol adds to a growing body of evidence that certain sugar substitutes may have unintended health consequences. Other studies have linked some artificial sweeteners to alterations in gut microbiota, metabolic dysfunction, and even an increased risk of certain types of cancer. While erythritol is not metabolized in the same way as other sweeteners, its newly discovered effect on blood clotting marks a significant departure from previous safety assumptions.
