Polyols are a group of organic compounds, primarily known for their role as low-calorie sweeteners in the food industry. These sugar alcohols are often used in products intended for people with diabetes or for those seeking alternatives to traditional sugar. 

They are present in a variety of products, from chewing gum to baked goods and beverages. In addition to their sweetening ability, polyols contribute to the texture and moisture of products, and may have beneficial properties for oral health, reducing the risk of dental cavities.
