Corn allergy

Corn allergy, also called maize allergy, is a very rare food allergy.[1] People with a true IgE-mediated allergy to corn develop symptoms such as swelling or hives when they eat corn or foods that contain corn.

Corn allergy can be a difficult allergy to manage, due to many food and non-food products that contain various forms of corn, such as corn starch, modified food starch, vinegar, and vanilla extract, among many others.

It is an allergy that often goes unrecognized.

Symptoms

Symptoms appear after exposure, and range from mild to severe.[1] As with other food allergies, most people who are allergic to corn have mild symptoms.[2]

As a result of a possible immunoglobulin E (IgE) allergy to corn, symptoms can resemble that of any other recognized allergy, including anaphylaxis. Reactions to corn derivatives, such as corn syrup, are also possible.[3]

Management

As with other food allergies, there is no cure.[2]

Most people who are allergic to corn cannot eat corn or anything containing proteins from corn.[1] Many people who are allergic to corn can still eat sugars purified from corn, such as corn syrup.[1]
