title: Current practices and improved recommendations for treating hereditary fructose intolerance.
abstract: A study of treatment practices of pediatric centers managing hereditary fructose intolerance and a review of recent literature on this subject were undertaken in an attempt to establish the degree of dietary liberalization allowable with age and the acceptability of foods containing trace amounts of fructose. The information was needed to plan optimal therapy and thus avoid the consequences of the disorder, namely intestinal dysfunction, metabolic imbalance, and hepatic and renal damage. Fifty responses to 113 letters to centers in Canada and the United States, as well as data from The Hospital for Sick Children, Toronto, Ontario, identified only 29 affected children and provided information on their care, including food lists and literature references. Major principles of treatment were similar, but the approach to allowing and quantifying dietary fructose differed. In response to the apparent need for standardization of treatment, the authors formulated improved recommendations for the control of dietary fructose (less than 1.5 gm/day). Only a few foods of vegetable origin are allowed, including a limited selection of vegetables and cereal products from grain endosperm. Repeated dietary counseling is advocated with regard to allowed foods, sweeteners, and medications to ensure long-term dietary compliance.
