What is Sucrose?

Sucrose is a relatively large sugar made by combining two smaller sugars called glucose and fructose. Sucrose occurs naturally in many fruits and vegetables. Take the Sucrose Intolerance quiz to see if your gas, bloating, and/or diarrhea after eating may be due to Sucrose Intolerance caused by Congenital Sucrase-Isomaltase Deficiency (CSID).
