Worth knowing
Xylitol (E967) creates a noticeable "cooling" sensation on the tongue as it dissolves, making it the perfect sweetener for mint chewing gums.
Conclusion

While it provides a low-calorie sweetness that does not cause tooth decay, excessive consumption of sugar-free products containing it can cause mild bloating or a laxative effect. It remains very safe for a standard diet.
