Xylitol, a sugar alcohol commonly used as a sweetener in various food products, has gained popularity due to its low glycemic index and dental health benefits. However, despite its perceived safety, there are growing concerns about the potential harmful effects of xylitol on human health and its serious implications for pets. Jurisdictions like the European Union have imposed regulations concerning its use, and the FDA has not classified xylitol as a food additive, indicating a need for caution. Understanding the risks associated with xylitol is essential for making informed dietary choices and safeguarding both human and animal health.
