Dietary elimination therapy has long been an option for patients with eosinophilic esophagitis (EoE) and remains the only therapy targeting the cause of the disease. Different dietary approaches have been described along the last 3 decades, and cumulative evidence has defined the effectiveness and usefulness of each approach. Elemental diets are highly effective to induce EoE remission, but unpractical in the vast majority of patients. Allergy testing-directed food restrictions resulted inefficient to induce remission in a significant proportion of patients (specially adults) and show a low concordance with the dietary causes of EoE. Empiric elimination diets are currently considered the most effective drug-free treatment for patients of all ages with EoE, after providing widely reproducible results. Highly restrictive empiric six-food elimination diets have paved the way to most efficient and less restrictive step-up approaches, which now include four-food and two-food elimination diets. The potential role of milk-elimination, especially in children, should be also considered. Multiple factors including demographics, nutritional status, patient and family lifestyles, social and financial support, and acceptance of repeated endoscopies influence the results of dietary therapy. Dietary therapy in EoE should be patient centered, and the patients and/or their families together with the medical provider should participate in the decision to set up this treatment. This article updates recent knowledge on dietary therapy for EoE and provides guideline to choose the most suitable alternative for patients with EoE, as well as practical tips to achieve the best results in clinical practice.
