A new study found that consuming a drink with erythritol, an artificial sweetener used in stevia and monk fruit products, doubled the risk of blood clotting in 10 healthy people.
Blood clots can lead to heart attacks or strokes. Previous research has also linked erythritol to a higher risk of stroke, heart attack, and death.
Lead author Dr. Stanley Hazen from the Cleveland Clinic said that after drinking erythritol, every person experienced an increase in platelet responsiveness, which can cause clotting.
In a separate group, consuming the same amount of sugar did not affect platelet activity. This study is the first to compare the effects of glucose and erythritol on platelet function.
Dr. Andrew Freeman from National Jewish Health called the study intriguing and raised concerns about the safety of sugar alcohols. The Calorie Control Council defended erythritol’s safety but noted the excessive amount used in the study.
Erythritol is a sugar alcohol found in fruits and vegetables, and it is commonly used in low-carb and keto products. It has no aftertaste, does not spike blood sugar, and is considered zero calorie.
The study published in the journal Arteriosclerosis, Thrombosis, and Vascular Biology involved 20 participants who drank either erythritol or sugar. Erythritol caused a significant increase in platelet activity, potentially increasing the risk of clotting, heart attack, or stroke.
Hazen’s previous study also found a link between erythritol and heart attack or stroke risk. He emphasized the importance of considering the impact of sugar alcohols on heart health, especially for those at high risk of cardiovascular disease.
