Corn Allergy also known as maize allergy is not diagnosed easily especially across the United States of America which consumes numerous products containing corn in some form or the other. It is not a very common food allergy and is usually difficult to diagnose.  Take a look at the facts related to corn allergy in case you need to take precautions.




The symptoms of allergy are evident when the body retaliates against a corn protein which it identifies as an antigen or harmful substance. The chemicals secreted into the blood stream result in a number of irritating and painful symptoms which might also become life threatening in extreme cases.  Apart from eating food prepared with corn, exposure to the pollens in form of flour or during handling of adhesives and surgical gloves which contain corn based materials may also set off the allergic reactions.


Symptoms & Signs of Corn Allergy


  • Difficulty in inhalation.
  • Tightening around the throat.
  • Wheezing.
  • Skin rashes or formation of hives.
  • Swelling of the face and tongue
  • Abdominal cramps and diarrhea.
  • Nausea and vomiting.


Some of the more rare signs of corn allergy are manifested as:-


  • Loss of concentration
  • Hyperactivity
  • Joint pains
  • Fatigue
  • Eczema
  • Dark circles under the eyes




Diagnosing  corn allergy is not always easy as the symptoms are basically the same as other food allergies which occur commonly. The following tests are usually conducted for ascertaining the condition.


  • RAST blood test
  • Skin Prick Test
  • Food Challenge Test
  • Food Elimination Tests
  • Maintaining a Diet Diary




The best way to treat corn based allergies is to eliminate it from your diet altogether. The best way to do that includes:-


  • Reading food labels carefully. You must also be aware that baking powder, sucrose, fructose and confectioner’s sugar contain corn.
  • Avoid consuming fast food totally.
  • Avoid handling adhesives and envelopes.
  • Use gloves made of fabric even when doing delicate work.
  • Stop consuming fried food that has been coated with batter.


Drugs for corn allergies are available OTC or can even be prescribed by a medical practitioner. Anaphylaxis requires emergency treatment and people prone to severe attacks are required to carry an auto injector containing epinephrine.


Risk Factors


The only known risk factor for corn allergies is family history. Children have a 75% of developing the allergy if both the parents suffer from it.


The ideal precautionary measure would be to avoid all corn based food and non-food stuffs if you have been diagnosed with corn allergy.
