Wheat allergy is part of the "Big Eight", one of the eight most common food allergies currently found here in the US. And similar to the other allergies, it too is growing in diagnosis and prevalence.

But what is typically referred to as "wheat allergy" is actually a collection of closely inter-related allergies. This is because there is a wide spectrum of wheat proteins, and each one can cause reactions.

The main protein classes include albumins, globulins, prolamins and glutelins. Over 40 different allergens in wheat have been detected, though gluten is the predominant factor. Many allergic individuals will also cross-react with related grains, such as barley and rye.

Related conditions include respiratory allergy to wheat pollen, an occupational disease that sometimes develops in bakers and food service workers, and is similar to typical grass allergies. And as explained in a previous post on the topic, celiac disease is also caused from exposure to gluten, but is different from wheat allergy.

Signs and Symptoms

An individual’s response to wheat allergens is similar to that found with most other food allergies. Eczema, hives, itching and swelling, abdominal pain and nausea are all typical. Migraines also seem to be a common symptom of exposure. In extreme cases, anaphylactic shock is possible. Special tests can help diagnose wheat allergy, although detection of these allergens can be harder than other food allergies.

Wheat allergy can also trigger two relatively unique conditions, 1) exercise-induced and 2) aspirin-induced anaphylaxis and urticaria. These can occur with other food allergens as well, but happen more frequently in relation to wheat allergies. Recent studies show that both aspirin and exercise increase the presence of gliadin, a common wheat allergen, in the blood stream. For this reason, sensitive individuals should talk with their doctor and possibly avoid aspirin products, and pay close attention to warning signs while exercising.

Some parents of autistic children also ascribe their child’s symptoms to wheat allergies, among other foods, although published data supporting this view is sparse.

Avoiding Wheat Products

An avoidance diet is the only certain defense. As noted, some wheat allergic people can still eat other grains and food products, allowing for substitutions such as rye bread. Gluten-free oats may be a useful source of cereal fiber, and rice flour is a commonly used alternative for those allergic to wheat.

As always reading labels is a must, considering the high prevalence of products that contain wheat. The Food Allergy Labeling Consumer Protection Act requires that labels be marked such that a 7-year old could read and understand the ingredients, and that all allergens are fully declared. For more information on this regulation, please see: Food Allergy Labeling

One question that we often hear from the parents of food allergic children is: Why have food allergies become so common these days?

That’s a difficult question, though many researchers are working hard for the answer. There are a variety of scientific theories that are currently being discussed. One potential cause could be the relatively recent introduction of genetically modified foods.

Genetically modified crops (GMOs) were introduced in the U.S. in the early 1990s, and foods created from these crops hit our supermarkets shortly thereafter. These crops have modified genes that allow them to grow faster, bear more fruit or even create their own insecticide. In layman’s terms, this engineering is the process of taking genes from one strain of an animal, plant, virus or bacteria, etc. and then inserting them into another, with the goal of reproducing characteristics of the original host species in the receiving species.

One example is a specific soybean variety genetically modified to be virtually immune to the popular Roundup herbicide, a chemical which kills almost any other plant. Of course, we consumers are then eating these modified soybeans.

How good are these foods for the human immune system? No one really knows! But some preliminary research studies have linked genetically modified foods with the creation of food protein antibodies in mice.

Another theory is called the “hygiene hypothesis” – which basically says that because we keep our homes, schools, other public places, and general environment too clean, we don’t give our immune systems something “worthy” to work on. The result is that our immune systems turn on themselves, and create problems such as the peanut protein, for example.

The hypothesis gained some credibility in the late 1980s, when health researchers compared the rates of allergies and asthma throughout the newly unified Germany.
Researchers assumed that the children growing up in the communist East, a poorer, dirtier environment, would suffer from more allergy and asthma than youngsters in the West, with its cleaner and more modern environment.

Actually, the opposite was found to be true. Children in the polluted areas of East Germany had lower allergic reactions and fewer cases of asthma than children in the West.

This is in line with the hypothesis, which suggests that when the human immune system lacks practice fighting bacteria and viruses, perhaps from an overly sanitary lifestyle, the system then overreacts to harmless substances like pollen.

In addition to a less sanitary environment, East Germany families tended to be larger, and rely more on the use of daycare for young children, two more factors that could attribute to their children being exposed to more microbes and potential irritants.

And there are many other potential culprits for the increase in food allergies – such as overall genetics, eating allergic foods during pregnancy, or use of vaccines in children. But there are no clear-cut or obvious reason(s) for the increases in food allergies, and for now these are just educated guesses, and nothing more.

We hope that science and medical research can one day unlock the mystery of food allergies, and how we can potentially treat or even cure them sometime in our future. Until then, the only completely reliable defense is avoidance…so the Allergy Free Shop will be here to provide the most up to date information and the allergy free foods and products that you need to keep your loved ones safe.

Soy allergy is a hypersensitivity to the dietary substances that derive from the soybean, and is one of the more common food allergies in the US. As with most food allergies, symptoms of allergic individuals can be minimal, moderate or severe; and include wheezing, a tingling or itchy sensation in the lips, mouth or throat, sneezing, light headedness and flush skin. Hives, rashes and asthma attacks can all occur.

In more serious cases the reaction to soy proteins in allergic individuals can become bronchospasm, or obstruction of the airway, and hypotension, a sudden drop in blood pressure. This may lead to anaphylaxis, a severe, whole-body allergic reaction that we have discussed before. In event of a severe allergic reaction, the victim should see a physician or immediately go to the emergency room, as anaphylaxis can be fatal if not treated immediately.

Severity of Reaction

Unlike some other food allergies, many people with soy allergy can tolerate small to moderate amounts of soy protein: the typical dose needed to induce an allergic response is about 100 times higher than for many other food allergens. In fact, 90% of sufferers can tolerate doses up to 400 mg.* As a result, not all of those allergic to soy need to avoid very minor sources of soy protein such as soy oil or soy lecithin.

But allergic individuals would still be wise to have epinephrine on hand in case of major ingestion, and also an antihistamine (such as Benadryl, or diphenhydramine) for more minor exposures or reactions.

Prevalence of Soy Proteins

Each "Big Eight" allergy presents its own set of issues and challenges. For some food allergies, like peanut, the primary concern is the severity of the reaction. In this regard, soy allergy reactions are not usually as “severe” as other food allergies. But there’s a trade off. Because of its nutritional profile and low cost, soy is used in all kinds of products these days.

Those allergic to soy protein should always read food ingredient labels carefully, and avoid any foods containing soybean. Many of these items clearly have "soy" in their names, such as soy flour, milk, nuts or sauce. Other items such as edamame, miso, natto or tofu contain soy proteins.

Textured vegetable protein is used in many restaurants and also contains soy, as do many flavorings and broths used in cooking. (In fact, a majority of fast food restaurants use soy protein in at least some of their products.) Most allergic individuals should also avoid dining at Asian restaurants completely, since most Asian foods and sauces can contain soy. Even some candies contain soy.

Making the situation even worse, some products don't list soy protein or soy flour on their labels - yet they still contain soy! There are still many latent issues resolving how soy should be regulated.

Treatment of Soy Allergy

An exclusion diet with continual avoidance of soy containing products is the only sure way to avoid allergic reactions. It is highly recommended that both children and adults with soy allergy carry epinephrine injectors in case of anaphylaxis.

Allergy Free Shop offers a wide variety of foods that are Soy Free. A few of our best sellers include Orgran’s Apple & Cinnamon Pancake Mix, Health Times' Brown Rice Cereal for babies, and EnerG Foods Brown Rice Loaf bread.
