Artificial sweeteners and sugar substitutes have been widely promoted as a way to enjoy sweetness without the calories. However, emerging research suggests that some of these substitutes—especially sugar alcohols like erythritol and xylitol—could pose serious health risks, including an increased likelihood of heart attacks and strokes.
Hidden Dangers of Sugar Substitutes
While many turn to sugar alternatives to manage weight or blood sugar levels, a Cleveland Clinic study raises major red flags about their impact on cardiovascular health. Researchers found that erythritol, a common sugar alcohol in “sugar-free” products, may trigger blood clot formation, increasing the risk of life-threatening cardiac events.
“This research suggests that even a standard serving of an erythritol-sweetened product may promote clot formation,” warns Dr. W. H. Wilson Tang, a leading cardiology expert. Given that blood clots are a major cause of strokes and heart attacks, these findings are alarming—especially for individuals already at risk.
Other Red Flags to Consider
- Xylitol may be just as dangerous. The same study found that higher xylitol levels correlated with increased heart-related incidents.
- Regulatory agencies once deemed these sweeteners safe, but new evidence suggests their long-term effects were underestimated.
- People with diabetes, heart disease, or metabolic syndrome may face the greatest risks.
- Frequent consumption raises concerns. Many unknowingly consume excessive amounts through diet sodas, protein bars, and “keto-friendly” snacks.
What Should You Do?
Experts urge caution. “For those at risk of heart disease, it may be safer to consume small amounts of natural sugar rather than relying on sugar alcohols,” advises Dr. Stanley Hazen of the Cleveland Clinic.
Read labels. Limit sugar substitutes. Talk to your doctor. Your heart health may depend on it.
