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
You should keep mannitol in mind if you eat large amounts of sugar-free products. Because it is poorly absorbed in the small intestine, excessive consumption can cause bloating, flatulence, and a strong laxative effect. It remains a bounded concern mainly for those consuming high quantities of diet candies and mints containing mannitol.
