Cost and accessibility of empiric food elimination diets for treatment of eosinophilic oesophagitis.

A step-up approach, commencing with a two-food elimination diet, instead of starting with a six-food elimination diet, may alleviate affordability barriers for most family types, which may enhance compliance. Clinicians should consider family type, financial situation, as well as accessibility of allergen-free foods in the patient's residential area when deciding on the most appropriate dietary or therapeutic treatment approach for eosinophilic oesophagitis.
