Corn Allergy Info

Corn allergies and being corn allergy free

Corn is a cereal grain with proteins that are similar to those in other cereal grains, such as wheat. Unlike wheat, which is a common food allergen, there are relatively few reports of allergic reactions to corn. However, the reports that do exist show reactions can be severe. These reports include anaphylaxis as a result of eating corn and corn-related foods, as well as severe reactions after exposure to cornstarch in surgical gloves.

Allergic reactions can occur as a result of eating both raw and cooked corn. Those with corn allergy may also react to corn pollen (typically with allergic rhinitis and/or asthma), grass pollen and cornstarch.

People with an allergy to one cereal grain, such as corn, often show positive allergy tests to other cereal grains.
