Study Links Popular Artificial Sweetener to Increased Health Risks

New Research Raises Concerns About Erythritol

A recent study conducted by the Cleveland Clinic has raised concerns about the popular artificial sweetener erythritol, commonly found in low-calorie and keto-friendly products. The research, published in the medical journal Arteriosclerosis, Thrombosis and Vascular Biology, suggests that consumption of erythritol may increase the risk of blood clots, potentially leading to heart attacks and strokes.

Study Findings and Implications

The small-scale study, involving 20 participants, found that consuming water sweetened with erythritol led to increased blood platelet activity, a factor associated with blood clot formation. Dr. Stanley Hazen, lead researcher and cardiologist at Cleveland Clinic’s Lerner Research Institute, stated:

“After drinking an erythritol-sweetened drink, you’re at heightened risk for clotting, and your platelet function changes – and this was seen in every subject who was tested.”

This recent study builds upon previous research from 2023, which linked erythritol to cardiovascular problems in a larger cohort of patients.

Expert Opinions and Caution

While the findings are concerning, experts not involved in the study urge caution in interpreting the results. Professor Alice H. Lichtenstein from Tufts University emphasised the need for context:

“We do not know enough about the overall effect of non-nutritive sweeteners vs. sugar to accurately assess their relative effects on health outcomes.”

Similarly, Professor Joanne Slavin from the University of Minnesota-Twin Cities advised:

“This study adds another piece to the puzzle, but should not alarm consumers that they are risking their health.”

Industry Response

The food industry, represented by the Calorie Control Council, has criticised the study’s methodology, citing the limited number of participants and the high dosage of erythritol used. Carla Saunders, president of the Calorie Control Council, stated:

“Consumers need to rely on science, and for 30 years, science has shown that erythritol is a proven safe and effective choice for sugar and calorie reduction.”

Recommendations and Future Research

Despite the conflicting views, researchers and experts agree on the need for further investigation. Dr. Hazen emphasised:

“I’m hoping this will be a call to arms for more research on this topic, especially given how prevalent and ubiquitous erythritol is as an artificial sweetener.”

In the meantime, experts suggest moderation in consuming foods and beverages containing artificial sweeteners. Professor Lichtenstein recommends:

“As much as possible, choose whole foods in their natural state and use common sense.”

As the debate continues, consumers are advised to stay informed about the potential risks and benefits of artificial sweeteners and to consult with healthcare professionals for personalised dietary advice.
