Sugar is a type of simple carbohydrate found naturally in a variety of foods, such as fruits, vegetables and milk. Sugar can also be produced industrially from sources such as sugar cane, sugar beet, or corn. Sugar generally has a sweet taste and is often used as a sweetener in food and beverages.
Sugar consists of two simple sugar molecules called monosaccharides, namely glucose and fructose. Glucose is the main source of energy for the human body and is an important blood sugar. Fructose, on the other hand, provides a more intense sweet taste and is often found in fruits.
