Study Limitations Important When Evaluating Xylitol Findings
A 2025 study on xylitol is limited in its ability to establish causality or reflect real-world consumption patterns. Decades of scientific evidence and global regulatory reviews continue to support the safety and benefits of xylitol, including its long-established role in oral health.
CCC statement
“The results of this study are contrary to decades of scientific evidence substantiating the safety and efficacy of low-calorie sweeteners such as xylitol by global health and regulatory agencies. While the authors used multiple methods, it should be noted that the findings are limited in their ability to establish association only. Further, one phase of the study included individuals who were already at increased risk for adverse cardiovascular events. These findings are a disservice to those who rely on alternative sweeteners as a tool to improve their health,” said Carla Saunders, President, Calorie Control Council. “Xylitol has been trusted as a great tasting low-calorie sweetener for over 60 years. It has proven dental benefits, including preventing plaque build-up and tooth decay is naturally occurring in foods such as strawberries, lettuce, and oats.”
Some additional factors to consider
- The findings are limited in their ability to establish causality, their application to real-world consumption, and extrapolation to the general public.
- Due to the observational design, both the untargeted and targeted metabolomic analyses included individuals who were already at increased risk for adverse cardiovascular events.
- Though convenient, in-vitro studies cannot mimic the complex physiological environment of the human body.
- The xylitol dose used in the study (30 g of xylitol dissolved in 300 ml water within 2 minutes) does not reflect a typical real-world serving.
