Xylitol is a naturally occurring sugar alcohol found in many fruits and vegetables. It is commonly used as a sugar substitute because it has a similar sweetness level to sugar but contains fewer calories. Xylitol is often used in sugar-free chewing gums, mints, and oral care products due to its dental benefits. It helps reduce the risk of cavities by inhibiting the growth of bacteria that cause tooth decay. Unlike other sugar substitutes, xylitol does not have a bitter aftertaste, making it a popular choice for various food and beverage products. It is also used in some pharmaceuticals and cosmetics. However, it is important to note that xylitol can be toxic to dogs, so pet owners should be cautious about keeping products containing xylitol out of reach of their pets.
