Wheat Allergy

Wheat allergy is an allergic reaction to wheat proteins. It is not the same as celiac disease, and a “gluten-free” label does not guarantee a food is free of wheat-derived ingredients.

  • Food safety
  • Allergens & labeling

Wheat allergy is an IgE-mediated reaction to wheat proteins that can affect the skin, gut and airways, and in some people causes anaphylaxis. It differs from celiac disease, an autoimmune condition in which gluten damages the lining of the small intestine. For allergen labeling, FDA defines wheat as any species in the genus Triticum and names common wheat, durum, club, spelt, semolina, einkorn, emmer, Khorasan and triticale. Wheat must be declared by name on FDA-regulated packaged foods. Wheat allergy affects up to 1% of U.S. children, and about two-thirds outgrow it by age 12.

Wheat flour is the base of most baking, so keeping it out of a wheat-free product takes real effort. People with wheat allergy rarely react to other common grains, though barley is an occasional exception, according to FARE. Gluten-free is not the same as wheat-free: FDA’s gluten-free rule requires less than 20 ppm gluten but allows wheat-derived ingredients that were processed to remove gluten. Bakers serving wheat-allergic customers must read full ingredient lists, not just front-of-pack claims.

Key facts

U.S. children affected
Up to 1%
Outgrow it by age 12
About two-thirds of children
FDA gluten-free limit
Less than 20 ppm gluten
What FDA counts as wheat
Any species in the genus Triticum

In a bakery or commercial kitchen

  • Declare wheat for spelt, durum, semolina, einkorn, emmer, Khorasan and triticale, since FDA counts all of them as wheat
  • Don’t use “gluten-free” as shorthand for “wheat-free”; confirm no wheat-derived ingredients are in the product
  • Keep separate, labeled sifters, scoops and bins for wheat-free flours, and mix wheat-free batches before wheat batches
  • Check glucose syrup, modified starch, soy sauce and seasonings on supplier specs, since FARE says these sometimes contain wheat
  • Back any gluten-free claim with testing or supplier data showing less than 20 ppm gluten

For home and cottage bakers

  • Blend several wheat-free flours to get a better texture, a tip FARE offers for wheat-free baking
  • Ask whether a guest has wheat allergy or celiac disease; the needs overlap but are not identical
  • Remember that play dough, salt-dough crafts and decorative wheat wreaths can contain wheat
