Side effects of sucrose, which is common table sugar, include tooth decay and risk for obesity in children and adults, according to MedlinePlus. Sucrose adds calories to the diet without providing any other nutrients.
Containing about half glucose and half fructose, sucrose originates from beet juice or sugar cane, states MedlinePlus. Other names for sucrose include raw sugar, granulated sugar and brown sugar, as well as confectioner's sugar and turbinado sugar. While sucrose is on the Federal Drug Administration's safe foods list, and individuals can safely use it in moderation, the American Heart Association recommends that no more than 150 calories a day come from the sweetener.
