What is not given in fructose intolerance patient?

Defects in Fructose Metabolism Cause DiseaseA lack of hepatic fructokinase causes essential fructosuria, which is a benign and asymptomatic condition. The absence of aldolase B, which cleaves fructose-1-phosphate, leads to hereditary fructose intolerance, which is characterized by profound hypoglycemia and vomiting after consumption of fructose (or sucrose, which yields fructose on digestion). Diets low in fructose, sorbitol, and sucrose are beneficial for both conditions.
