Approaches to diet therapy for eosinophilic esophagitis

Purpose of review The aim of this review is to highlight recent advances in dietary therapy for eosinophilic esophagitis (EoE). Recent findings An empiric elimination diet step-up strategy is now well established as the initial approach for dietary treatment. The most common food triggers are by far cow's milk, followed by wheat and egg. Legumes seem to be important solely in Spain and other Mediterranean countries, where they are regularly consumed. Retrospective efficacy data on cow's milk elimination diet in children vary from 25 to 65%. The recently described esophageal prick test did not detect local reaction to the most common food triggers described for EoE. Summary Within the step-up approach, the specific food group or groups to be first eliminated and whether if it will depend on the geographical setting and food consumption habits remain unknown. Prospective studies on cow's milk elimination diet in children and adults are definitely warranted. Better food allergy testing, identifying specific antigens involved in each food group, should be developed for an individualized therapy. As for disease prevention, we undoubtedly need to understand why foods we have been consuming since the Neolithic age have caused EoE just over the past few decades.
