Malabsorption of apple juice and pear nectar in infants and children: clinical implications.
Ingestion of fruit juices in which there is an imbalance between glucose and fructose (apple, pear nectar) and the presence of sorbitol is one of the major causes of the syndrome of chronic, nonspecific diarrhea of infancy and childhood. Stools in the condition at time of symptoms are acidic with a pH < 5.5, Clinitest positive, but free of blood and white cells. Lactose and sucrose breath hydrogen tests are normal but breath hydrogen is elevated if measured between 60-120 minutes after the offending juice is taken in sufficient quantity to elicit symptoms. Elimination of the offending juices immediately stopped the diarrhea in all of the cases. Three cases are presented documenting the variability of symptoms including one adolescent who became symptomatic while on a fruit and juice diet.
