Xylitol is a sugar alcohol derived from plants such as birch trees and corn husks, notable for its sweetening properties and beneficial dental effects. Approximately as sweet as sucrose (table sugar), xylitol has about two-thirds the calories and a low glycemic index, making it a popular sugar substitute for individuals managing their weight or blood sugar levels. Unlike sugar, xylitol does not promote tooth decay; in fact, it inhibits the growth of bacteria that cause dental cavities, making it a key ingredient in oral care products like chewing gum and toothpaste. Furthermore, xylitol is well-tolerated by most people, although excessive consumption may cause digestive discomfort due to its laxative effect in some individuals. Its versatility extends beyond oral hygiene to include applications in baking and confectionery, where it contributes a mild cooling sensation and helps maintain moisture in foods. As a natural sweetener with dental benefits and broader culinary uses, xylitol continues to gain popularity as a healthier alternative to traditional sugars.
