What is a wheat allergy?

A wheat allergy is a reaction by your child's immune system to wheat. Our immune systems normally respond to bacteria or viruses that attack the body. A food allergy occurs when the body's immune system mistakenly believes that a harmless food substance (such as proteins found in wheat) is harmful. In order to protect the body, the immune system creates substances called antibodies to that food. The next time you eat that particular food, your immune system releases huge amounts of chemicals, such as histamines, to protect the body. This is what causes the symptoms.

Wheat is among the 8 foods that are responsible for most food allergies in children. The other foods include milk, soy, peanuts, tree nuts (such as walnuts and cashews), eggs, fish, and shellfish.

There are 4 types of protein found in wheat, (albumin, globulin, gliadin, and gluten). Your child may be allergic to any one of these proteins.

Wheat allergy is often confused with celiac disease. Celiac disease is a digestive problem that causes the body to react to all types of gluten, which is found in wheat, barley, and rye grains. Children with wheat allergy may or may not react to oats, rye, and barley. Ask your healthcare provider if your child needs to avoid these grains as well.

What are the symptoms of an allergic reaction to wheat?

If you think your child is allergic to wheat or any other food, it is important to get a diagnosis from your healthcare provider or allergist.

Symptoms may include:

  • skin reactions such as eczema, hives, swelling (typically eyelids and mouth)
  • stomach cramps, nausea, and vomiting
  • wheezing or trouble breathing
  • itching eyes
  • runny or stuffy nose, or sneezing.

Although rare, it is possible to have an allergic reaction called anaphylactic shock. This is a serious reaction that is sudden, severe, and can involve the whole body. It can cause swelling of the mouth and throat, dangerously lower blood pressure, and trouble breathing. This type of reaction is a medical emergency. It is treated with epinephrine (a medicine that is given by injection). Usually parents or caregivers of children who have severe allergic reactions carry their own shot kits, just in case of emergency.

An allergic reaction to a food usually starts within minutes but may be delayed 2 to 4 hours. It usually lasts less than 1 day. The more severe the allergy, the smaller the amount of food it takes to cause a reaction.

How will this affect my child's diet?

Your child will need to avoid all sources of wheat. Wheat is found in hundreds of foods such as most bread products, pastas, and items made with flour. Many processed foods contain flour-based thickeners. You will need to change the way you order, shop and prepare foods.

If you are breast-feeding, eliminate the food your child is allergic to from your diet. Food allergens can be absorbed from your diet and enter into your breast milk

The first step is to learn to read labels and become familiar with ingredients that contain wheat or wheat products. Always ask about ingredients if you are not sure. Study the lists below to learn more about foods and ingredients to watch out for.

Foods that contain wheat

  • Most breads, cakes, cookies, and pastries
  • Bread crumbs
  • Pasta
  • Couscous
  • Many breakfast cereals
  • Kamut (cereal grain)
  • Crackers
  • Enriched flour
  • Whole wheat flour
  • Graham flour
  • Wheat (bran, germ, malt, starch, gluten)
  • Semolina
  • Spelt
  • Farina
  • Durum
  • Bulgur
  • Cracker meal
  • Gluten (one of the wheat proteins)
  • High-gluten flour; high-protein flour
  • Vital gluten.

Foods/ingredients that often contain wheat (check the label or ask)

  • Modified food starch
  • Gelatinized starch
  • Hydrolyzed vegetables protein
  • Natural flavorings
  • Soy sauce
  • Vegetable gum or vegetable starch.

You will need to prepare more meals from scratch using whole natural foods. Wheat-free food products, such as bread and pancake mixes, noodles, and substitute flours such as potato, rice, soy, and corn are often available in health food markets and the natural foods section of grocery stores. There are also Web sites where you can buy specialty foods online (such as http://www.allergygrocery.com). To be on the safe side, buy products that have an 800 number for you to call and ask about ingredients.

How do I avoid cross contamination?

Cross contamination can be problem when trying to avoid wheat. Wheat can come in contact with other foods during processing and in preparation, even if not included in the recipe. At home, use separate cutting boards, bowls, and utensils and label all food containers.

Restaurant Meals

  • When dining out, the waiter or waitress about the allergy. Order simple dishes without sauces unless you're sure there is no wheat in them.
  • Make sure the food preparation equipment, such as food processors, cutting boards, pans, and utensils are not used for recipes containing wheat or wheat flours as well as for other recipes.
  • Avoid deep fried foods, such as French fries. They are often cooked in the same oil as "breaded" items.
  • Avoid Chinese, vegetarian dishes, and seafood salads. Meat substitutes or imitation crab products may contain wheat.

Reading labels to avoid allergens has become a lot easier. Foods that contain milk, eggs, fish, shellfish, peanuts, tree nuts, wheat, or soy products must list the food in plain language on the ingredient list. For example, hydrolyzed vegetable protein (wheat). These possible allergens must be listed even if they are part of a flavoring, coloring, or spice blend. There are still some things to watch out for when reading food labels:

  • Read the label every time. The manufacturer may change ingredients.
  • Watch out for the words “may contain”. Milk, peanuts, or other allergens may not be ingredients, but the food may be made in a factory that also produces these foods. If you see the words “may contain”, there may be very little of the allergen, or there may be a large amount.
  • Words on the package such as “peanut free” or “milk free” do NOT mean that the food is completely without these allergens. You still need to read the label carefully to make sure that it does not contain ingredients derived from allergens.

It is very important for you to know less common names and scientific names for food ingredients.

How can I provide my child with a healthy diet that tastes good?

Your child can still have a healthy diet. The main nutrients found in wheat are carbohydrate, protein, fiber, folic acid, niacin, zinc, magnesium, and iron. Your child can get all these nutrients from other foods, but there is a risk for not getting enough B vitamins. Other sources of B vitamins include dark leafy vegetables, bananas, asparagus, oranges, peanuts, and other fortified grains such as corn meal and rice flours. Ask your healthcare provider or dietitian if your child should take vitamin supplements.

How do I modify recipes?

Most recipes can be modified to fit a wheat-free diet. There are several good wheat-free or gluten-free cookbooks and web sites with recipes.

How can I keep my child safe at school?

  • Teach your child not to eat foods unless they are safe. Even young children can grasp this concept, especially once they have gotten sick after eating a particular food).
  • Prepare your child's lunch at home.
  • Talk with teachers and the school administrator regarding your child's needs. Ask teachers to keep an eye out and explain the situation to other children if needed.
  • Have the teacher call you if there is a special event or party planned so that you can bring a few modified treats that your child enjoys and can share with other kids.
  • Make a card that lists foods and ingredients that should be avoided and give one to the teacher. The card can also help older children make decisions when out with friends.
