What is sucralose?
Sucralose is a no-calorie sweetener that contributes sweetness to foods and beverages without adding calories or carbohydrates. It is made from a process that begins with regular table sugar (sucrose); however, sucralose is not sugar. Three select hydrogenoxygen groups on a sucrose molecule are replaced with three chlorine atoms, resulting in a no-calorie sweetener that is about 600 times sweeter than sugar. Although sucralose provides sweetness, its structure prevents enzymes in the digestive tract from breaking it down. Most consumed sucralose (about 85 percent) is not absorbed. Of the small amount absorbed (about 15 percent), none is broken down for energy, so sucralose does not provide any calories. All absorbed sucralose is excreted quickly in the urine (Roberts 2000, Magnuson 2016).
