The smell of sweet and savory baked goods is often difficult to resist. However, those with a wheat allergy may experience adverse symptoms when eating certain baked goods. 

A wheat allergy is an immune response to proteins in wheat. A wheat allergy may trigger an immunoglobulin E (IgE) response from the immune system. IgE is an antibody naturally found in the body that alerts the immune system when the body comes into contact with allergens.

Who is Most at Risk for a Wheat Allergy?

Wheat allergies are more common in children, though many outgrow them as they get older. While wheat is not one of the most prevalent allergens in the U.S., certain people are at higher risk.

People with celiac disease — an autoimmune condition that causes an allergy to gluten (a protein found in wheat, rye, and barley). Celiac disease is a hereditary condition often passed on from one or both parents. Not everyone shows signs of celiac disease right away. Symptoms can increase over time with age.

What are the Symptoms of a Wheat Allergy?

Those with a wheat allergy may experience different symptoms depending on the severity of their allergy. Symptoms may begin within a few minutes of eating wheat.

Wheat allergy symptoms a person with a wheat allergy may experience after consuming wheat proteins include:

• Fatigue

• Constipation

• Abdominal pain

• Headache

• Shortness of breath

• Nausea

• Hives

• Congestion

In severe cases, a person may experience anaphylaxis — a life-threatening allergic reaction. Be sure to seek emergency help if you have breathing issues, severe chest pain, or trouble swallowing. 

What Foods Should You Avoid?

The Food Allergen Labeling and Consumer Protection Act (FALCPA) requires distributors to clearly label foods containing wheat. This is typically listed right below the main ingredient list on the label of a product. 

Sources of wheat you may not be aware of include:

• Soy sauce

• Natural flavoring

• Gelatinized starch

• Vegetable starch

• Salad dressing

• Taco seasonings

• Beef jerky 

• Veggie burgers

• Frozen vegetables

Some cosmetic items also contain wheat. In case of emergency, a healthcare provider may recommend carrying around an EpiPen (epinephrine injection). An EpiPen is used during emergencies to manage symptoms until emergency help arrives.

Recommended Wheat Alternatives

While rice and other grains are staples of many meals, there are substitutions you can eat instead. 

Those with a wheat allergy may consider consuming the following alternatives:

• Arrowroot starch

• Millet

• Quinoa

• Sorghum

• Buckwheat

• Amaranth

Many people with a wheat allergy follow a gluten-free diet. This consists of predominantly purchasing products labeled gluten-free. You can also speak with a nutritionist or a licensed healthcare provider about ways to change your diet. 

Tips for Avoiding Cross-Contamination with Wheat

Even if a person doesn’t eat foods that contain wheat, cross-contamination can occur in facilities. Be sure to thoroughly clean cooking surfaces before eating. The risk of cross-contamination is higher at restaurants and buffets as well.
