Erythritol and Stroke Risk: What the Latest Research Reveals
Recent research has raised concerns about a potential link between erythritol, a popular sugar substitute, and an increased risk of cardiovascular events, particularly stroke. While frequently enough marketed as a healthy alternative to sugar, studies suggest erythritol may negatively impact blood vessel function and contribute to clot formation.
What is erythritol?
Erythritol is a sugar alcohol used as a sweetener in a variety of foods and beverages,including diet sodas,sugar-free candies,and baked goods. It contains very few calories and doesn’t raise blood sugar levels like traditional sugar, making it attractive to people managing diabetes or trying to reduce their calorie intake. It’s about 80% as sweet as sugar. Mayo Clinic
The University of Colorado Study and Blood-Brain Barrier
Researchers at the University of Colorado Boulder conducted laboratory experiments exposing human cells to erythritol at concentrations found in some diet drinks. The study, published in 2023, revealed alarming changes in cells of the blood-brain barrier, the protective mechanism regulating substance passage to the brain. Specifically, the research showed a decrease in the secretion of proteins that dissolve blood clots and an increase in the ability of blood vessels to narrow. Columbia university Irving Medical Center Thes changes could potentially increase the risk of clots obstructing blood flow to the brain, potentially leading to ischemic stroke.
Ischemic Stroke and Rising Rates
Ischemic stroke occurs when a blood vessel supplying the brain is blocked, depriving brain tissue of oxygen and nutrients. This can cause cell damage and neurological deficits. the publication of the University of Colorado study coincided with reports of a significant increase in stroke rates among younger adults, with approximately a 15% rise since 2011. American Heart Association While many factors contribute to stroke risk, the potential role of artificial sweeteners like erythritol is now under scrutiny.
Earlier Research: Heart Event risk
The 2023 University of Colorado study builds upon previous research. A separate study involving over 1,000 patients found that individuals with higher levels of erythritol in their blood were approximately twice as likely to experience serious heart events, such as heart attack or stroke, compared to those with lower levels.

Comparison to Other Sweeteners
Unlike artificial sweeteners like aspartame and sucralose, which are manufactured, erythritol occurs naturally in small amounts in the human body. Aspartame and sucralose are substantially sweeter than sugar – approximately 600 times sweeter – while erythritol is about 80% as sweet. FDA
Ongoing Research and Considerations
It’s important to note that the university of Colorado study was conducted on cells in a laboratory setting,which is a limitation. Further research is needed to confirm these findings in human clinical trials. Researchers emphasize the need for more studies to understand the long-term effects of sugar substitutes on blood vessels and the gut microbiome.
Key Takeaways
- Erythritol, a common sugar substitute, may be linked to an increased risk of cardiovascular events, including stroke.
- Laboratory studies suggest erythritol can negatively impact blood vessel function and promote clot formation.
- Recent research indicates a rise in stroke rates among younger adults.
- More research is needed to fully understand the long-term effects of erythritol and other artificial sweeteners.
Frequently Asked Questions (FAQ)
Q: Should I stop using products containing erythritol?
A: The research is still emerging. if you have concerns, discuss them with your doctor. It’s generally advisable to consume sugar substitutes in moderation.
Q: Are all sugar substitutes harmful?
A: Not necessarily. Different sugar substitutes have different chemical structures and may have varying effects on the body. More research is needed to assess the safety of each one.
Q: What are some alternatives to erythritol?
A: Options include stevia, monk fruit, and allulose. Though, even these alternatives should be consumed in moderation.
as research continues, staying informed about the potential health effects of sugar substitutes is crucial for making informed dietary choices.
