Cleveland Clinic study adds to increasing evidence that sugar substitute erythritol raises cardiovascular risk

Aug. 8, 2024
Erythritol is a common artificial sweetener found in baked goods, beverages, gum and candy.

New Cleveland Clinic research shows that consuming foods with erythritol, a popular artificial sweetener, increases risk of cardiovascular events such as heart attack and stroke.

The findings, from a new intervention study in healthy volunteers, show erythritol made platelets (a type of blood cell) more active, which can raise the risk of blood clots. Sugar (glucose) did not have this effect.

Published in Arteriosclerosis, Thrombosis and Vascular Biology, the research adds to increasing evidence that erythritol may not be as safe as currently classified by food regulatory agencies and should be reevaluated as an ingredient. The study was conducted by a team of Cleveland Clinic researchers as part of a series of investigations on the physiological effects of common sugar substitutes.

The current research builds on the team’s previous study, published last year in Nature Medicine, which revealed that cardiac patients with high erythritol levels were twice as likely to experience a major cardiac event in the following three years compared to those with low levels. The study also discovered that adding erythritol to patients’ blood or platelets increased clot formation. These findings were confirmed by pre-clinical studies.

The new human intervention study was designed to more directly observe the effects on platelets following erythritol ingestion at a dose typically contained in a “sugarless” soda or muffin. In 20 healthy volunteers, researchers found that the average erythritol level after eating increased over 1,000 times in the group that consumed erythritol compared to their initial levels. Results also revealed participants showed a significant increase in blood clot formation after consuming erythritol, but no change was observed after consuming glucose.
