The six food elimination diet is one way to treat EoE. This is done by eliminating the six most common allergens for EoE: fish, nuts, eggs, soy, wheat and dairy. After six weeks, patients return for an upper endoscopy and biopsies are taken to test for eosinophil count. If the eosinophils are gone, then each food is re-introduced one at a time to identify which food is your trigger food. Listen to Dr. Jeff Alexander at Mayo Clinic Rochester to learn more about the diet.
