Xylitol What Is Xylitol? Xylitol is a chemical compound that’s classified as a sugar alcohol and is widely used as a food additive and sugar substitute. Indeed, while xylitol has a naturally sweet taste and looks and tastes just like regular table sugar, it is about 40% lower in calories than sugar (providing about 10 calories per teaspoon, versus 16 per teaspoon for sugar). In addition, unlike sugar, xylitol does not cause glycemia to spike and is considered a low glycemic index sweetener. https://www.nationalnutrition.ca/alternative-sweeteners/xylitol.html #Xylitol
