Corn Allergy Basics

Corn Allergy:

A corn allergy is an immune reaction to corn proteins.

Symptoms of corn allergy:

Symptoms of corn allergy can be divided into 3 categories:

  • Gastrointestinal – nausea, vomiting, stomach pain, diarrhea, gas, bloating
  • Respiratory – wheezing, asthma, nasal congestion, runny nose
  • Skin – hives, itching, swelling of tongue or face, rash, eczema

Anaphylaxis due to corn allergy is extremely rare.

The corn-free diet:

Following a corn-free diet requires the elimination of the following types of foods:

  • Corn
  • Cornmeal
  • Corn flour
  • Corn starch
  • Corn syrup
  • Popcorn

Corn oil may not contain any corn protein, and therefore may be tolerated by corn-allergic individuals. However, products can be contaminated with corn protein during processing, so a highly sensitive person should avoid corn oil.

Nutritional needs:

Corn is a good source of folate, vitamin C, niacin, thiamine and fiber. These nutrients can be found in beans, vegetables and fruits, fortified breakfast cereals, some meats, liver and whole grains.
