Mythbuster: Is it a myth to think that someone can have both IgE- and non-IgE-mediated food allergy? 

November 3, 2023

FACT: Some people have both categories of food allergy: Immunoglobulin E (IgE)- and non-IgE-mediated food allergy.  

With an IgE-mediated food allergy, symptoms result from the body’s immune system making IgE antibodies when a specific food is eaten.  

In contrast, a non-IgE-mediated food allergy involves other components of the immune system causing symptoms, rather than IgE antibodies.  

Examples of allergic conditions which include non-IgE-mediated food allergy are eosinophilic esophagitis (EoE) and food protein-induced enterocolitis syndrome (FPIES).
