Wheat Allergy

Wheat – along with soy, it’s arguably one of the most challenging of the top eight food allergens to manage because it’s found in so many products.  Approximately 75 percent of all grain products in the U.S. are made from wheat flour, according to the National Wheat Growers Association.

Large-scale studies of wheat allergy in the U.S. have not been conducted, but it’s estimated that approximately 0.4 percent of children and 0.5 percent of adults are allergic to wheat.

Wheat allergy is typically outgrown by adulthood -- approximately 65 percent of children with wheat allergy will outgrow it by the time they are 12.

As with reactions to other foods, the symptoms of a wheat allergy may include:

  • Hives or skin rash
  • Nausea, stomach cramps, indigestion, vomiting, diarrhea
  • Stuffy/runny nose
  • Sneezing
  • Headaches
  • Asthma

Symptoms may range from mild to severe.  A severe allergic reaction is known as anaphylaxis, which starts rapidly and may cause death.

Treatment for wheat allergy includes strict avoidance of wheat ingredients.

Your allergist may prescribe epinephrine (adrenaline), available in an auto-injector, and antihistamine, to treat your symptoms. It is important to note that while antihistamines may help relieve some symptoms, it is not a substitute for epinephrine, which is the first-line treatment for life-threatening anaphylaxis.

Families managing wheat allergy often find wheat is contained in a myriad of foods – cereals, pastas, crackers, and even some hot dogs, sauces, and ice cream. Wheat is also found in non-food items such as play-dough, and cosmetic and bath products. As with any food allergy, ingredient label reading is a must.  Options for wheat-free grocery shopping include foods made from other grains such as corn, rice, quinoa, oats, rye, and barley.

One of the challenging aspects of managing wheat allergy is baking. While there’s no simple substitution for wheat as an ingredient, baked goods such as breads, muffins, and cakes may be successfully made using a combination of non-wheat flours, such as those made from rice, corn, sorghum, soy, tapioca, or potato starch.

Celiac Disease and Gluten Intolerance

Wheat allergy is different from celiac disease (also known as celiac sprue) or gluten intolerance. Individuals with celiac disease or gluten intolerance are sensitive to gluten, a protein found in cereal grains such as wheat, rye, barley and oats.  People allergic to wheat must only avoid wheat protein while those with celiac disease must avoid all the above grains. 

A reaction to gluten includes symptoms such as:

  • Abdominal pain
  • Constipation
  • Diarrhea
  • Weight loss
  • Occasionally a very distinct skin rash

Celiac disease is both a food intolerance and autoimmune disorder.  Researchers estimate that approximately 1 percent of the U.S. population has celiac disease.

Frequently Asked Questions

What grains are good for someone allergic to wheat?

Individuals with wheat allergy can generally tolerate grains such as aramanth, barley, buckwheat, corn, oats, millet, rice, rye, sorghum, and quinoa. Your allergist can provide you with guidance on which grains are safe for you.

Are gluten-free products safe for those with a wheat allergy?

A gluten-free product may be safe for those who are allergic to wheat because the product should not contain wheat ingredients. However, because a product that is marketed as “gluten-free” must be free of rye and barley in addition to wheat, those who must avoid only wheat may be limiting themselves. More importantly, people managing food allergies should never rely on a “free-from” label as a substitute for thoroughly reading a complete ingredient label.
