sugÂ·ar. n. 1. A sweet crystalline or powdered substance, white when pure, consisting of sucrose obtained mainly from sugarcane and sugar beets and used in many foods, drinks, and medicines to improve their taste. Also called table sugar.
Sugar is an important source of food energy. During digestion, all food carbohydrates (starches and sugars) break down into single molecule sugars. These sugars are absorbed from the intestine into the blood stream and travel to the cells, where they are used to provide energy for cellular functions. In parts of the world where people suffer from energy malnutrition and are undernourished, sugar is valued as an inexpensive source of energy to support human activities.
