Sugar alcohols, also known as polyols, are a type of carbohydrate that can be found naturally in small amounts in various fruits and vegetables. However, they are also commonly used as sweeteners in a wide range of products, including sugar-free gum, candy, and baked goods. Despite their popularity, there is still much to be learned about the effects of sugar alcohols on the human body. In this article, we will delve into the world of sugar alcohols and explore what they do to the body, including their potential benefits and drawbacks.
Introduction to Sugar Alcohols
Sugar alcohols are a type of sugar substitute that is derived from fruits and vegetables. They are called “sugar alcohols” because they have a chemical structure that is similar to both sugars and alcohols. Some common types of sugar alcohols include xylitol, sorbitol, mannitol, and erythritol. These substances are often used as low-calorie sweeteners because they contain virtually no calories and do not raise blood sugar levels.
Natural Occurrence of Sugar Alcohols
Sugar alcohols can be found naturally in small amounts in various fruits and vegetables, such as apples, pears, and plums. They are also present in some types of mushrooms and seaweed. However, the amounts of sugar alcohols found in these natural sources are typically very small, and it is unlikely that an individual would consume enough to have a significant impact on their health.
