Food elimination diets in eosinophilic esophagitis: Practical tips in current management and future directions.

???displayArticle.abstract???
Eosinophilic esophagitis (EoE) is a chronic, antigen-mediated disease of the esophagus characterized by symptoms of esophageal dysfunction and an eosinophil-predominant inflammation. Seminal reports identified the role of food allergens in the pathogenesis of the disease by demonstrating that food avoidance could lead to the resolution of esophageal eosinophilia in EoE patients. Although pharmacological treatments for EoE are increasingly being investigated, the exclusion of trigger foods from the diet still represents a valuable option for patients to achieve and maintain disease remission without drugs. Food elimination diets are variegated, and one size does not fit all. Accordingly, before starting any elimination diet, patients' characteristics should be thoroughly evaluated, and a rigorous management plan should be defined. This review provides practical tips and considerations to succeed in the management of EoE patients undergoing food elimination diets, as well as recent advances and future perspectives on food avoidance strategies.
