Polyols are a type of carbohydrate that are often used as sugar substitutes. They are also known as sugar alcohols and include compounds like sorbitol, mannitol, and xylitol. Polyols are found naturally in some fruits and vegetables, and they can also be manufactured for use in food products. They provide sweetness with fewer calories than regular sugar and have a lower impact on blood sugar levels. In addition to their use in food, polyols are commonly found in sugar-free candies, chewing gum, and baked goods. They can also serve as humectants, helping to retain moisture in products. While polyols are generally safe for consumption, excessive intake may lead to digestive discomfort for some individuals.
