Recognizing Soy Allergy Symptoms

Soy comes from soybeans, which are in the legume family along with beans, lentils, peas, and peanuts. Some people are allergic to just one type of legume; others are allergic to more than one. Allergy to soy is more common in infants and kids than teens and adults, but can develop at any age.

When someone with a soy allergy has something with soy in it, the body releases chemicals like histamine. This can cause symptoms such as:. Allergic reactions to soy can differ. Sometimes the same person can react differently at different times. Some reactions to soy are mild and involve only one system of the body, like hives on the skin.

Other times the reaction can be more severe and involve more than one part of the body. Rarely, soy allergy can cause a severe reaction called anaphylaxis. Anaphylaxis might start with some of the same symptoms as a less severe reaction, but can quickly get worse. The person may have trouble breathing or pass out.

More than one part of the body might be involved. If it isn't treated, anaphylaxis can be life-threatening.

If your child has a soy allergy or any kind of serious food allergy , always keep two epinephrine auto-injectors available in case of a severe reaction. An epinephrine auto-injector is a prescription medicine that comes in a small, easy-to-carry container.

It's easy to use. Your doctor will show you how. Kids who are old enough can be taught how to give themselves the injection. The epinephrine should be nearby, not left in a locker or in the nurse's office. The doctor can also give you an allergy action plan, which helps you prepare for, recognize, and treat an allergic reaction.

Share it with anyone who takes care of your child, including relatives, school officials, and parents at play dates. Also consider having your child wear a medical alert bracelet.

Every second counts in an allergic reaction. If your child starts having serious allergic symptoms, like swelling of the mouth or throat or difficulty breathing, give the epinephrine auto-injector right away.

Also give it right away if the symptoms involve two different parts of the body, like hives with vomiting. Soy is one of the “big eight” allergens next to foods like eggs , cow’s milk, fish, shellfish, peanuts, tree nuts, and wheat.

These foods account for over 90 percent of all food allergies. In the U. In addition to the sensitivity problem associated with soy-contain foods, soybean production has become widely notorious for using genetically-modified organisms GMOs , raising eyebrows among conscious consumers.

GMO soybeans, which are most commonly produced in the U. Studies observing both non-GMO and genetically modified tofu products which is predominantly soy-based indicate that GMO soy can result in adverse effects on the human body that are not immediately felt but the effects can arise several years later 3.

Many adverse reactions to soy exposure are not considered true allergies. In general, soy allergy is an IgEimmune system response that can have an effect on multiple organs of the body. Conversely, experiencing isolated digestive symptoms or other symptoms such as tiredness, skin rashes, migraines, headaches and low mood can indicate a soy intolerance, not an allergy.

This can show up as gastrointestinal and digestive problems, such as cramping or diarrhea, as well as headaches, dizziness, and nausea as well as the other symptoms mentioned above. On the other hand, symptomatic reactions from a soy allergy are often much more intense.

They can rapid and severe, or they may occur gradually within 30 minutes or up to two hours later. With an allergy, the body reacts to soy protein as if it were fighting a disease-producing microorganism. With an intolerance or sensitivity the immune system can also be triggered but the symptoms are delayed and that’s why the test to do for soy intolerance or sensitivity is the soya-specific IgG test not a soya-specific IgE allergy test.

For most individuals who have a true soy allergy, the symptoms are generally uncomfortable and pass with time. However, in rare cases, an allergic reaction to soy can be highly severe and even life-threatening. The signs of a soy allergy usually develop within a few minutes after consuming a soy-containing food or drink, but in some cases, the onset can take over an hour or two.

The most common soy allergy symptoms can include:. In many cases, mixed reactions with multiple different symptoms can occur. In very severe allergic reactions, symptoms of anaphylaxis can manifest, which are extreme and potentially life-threatening.

The signs of a soy sensitivity or soy intolerance can be slower to present, and will may cause discomfort but are not life threatening. The duration of soy allergy symptoms can vary widely from person to person. Factors like stress and emotional state can contribute to the severity and duration of allergic reactions, as well as factors like age, immunity, and other biological conditions.

In general, soy allergy symptoms can last for about 48 hours on average after a reaction begins. However, some individuals who are soy-allergic have reported their symptoms diminishing within a few hours after onset.

In other severe cases, allergy symptoms can linger for several days to even lasting upwards of a week or longer. The longevity of allergy symptoms can also be viewed from a development perspective, such as when an allergy is detectable in children and when allergic reactions dissipate.

Because soy allergy is one of several food allergies that commonly begins during the early stages of life, this is a particular topic of interest among parents with soy-allergic children.

Soy allergy usually occurs within the infant and toddler stages before the age of 3. Studies indicate that 50 percent of soy-allergic children outgrew their allergy by age 7 years, and 69 percent kicked allergic symptoms by age 10 years 4.

Diagnosing a soy allergy can be as complicated as the symptomatic reactions behind the condition. Because allergy symptoms can vary widely from person to person, an individual may not always experience the same allergic symptoms amid every reaction.

This can make diagnosing a soy allergy versus a myriad of other potential allergic reactions a challenge. In either case, you’ll also want to educate yourself about the many common names, ingredients, and forms that soy comes in, as to avoid triggering symptoms. There are also many different types of foods that can be derived from soy but may not contain the word “soy” or “soya” in the name, such as:.

Some individuals can tolerate certain processed soy products, such as soy lecithin, without having an allergic reaction. Because soy intolerance and allergy can vary by person, it can be very helpful to identify the specific ingredients and food types that trigger your symptoms.

Soy Allergy | Patient Education | UCSF Health

Your allergist will interpret these results and use them to aid in a diagnosis. While both of these diagnostic tools can signal a food allergy, neither is conclusive.

A negative test is more helpful to rule out a food allergy. Neither test, by size of the skin test wheal or the level of IgE antibodies, necessarily predicts the severity of an allergic reaction to soy.

For a definitive diagnosis, the allergist may wish to conduct an oral food challenge, in which the patient is fed gradually increasing amounts of the suspected allergy-causing food under strict supervision.

Experienced personnel, emergency medication and emergency equipment must be on hand during this procedure. Oral food challenges also may be performed to determine if a patient has outgrown a food allergy. As with other food allergies , the best way to manage a soy allergy is to avoid consuming products that contain soy.

Soy is one of the eight allergens that fall under the labeling requirements of the Food Allergen Labeling and Consumer Protection Act of This means that manufacturers of packaged food items sold in the United States and containing soy or a soy-based ingredient must state, in clear language, the presence of soy in the product.

Soy or derivatives of soy are found in some infant formulas, canned broths, soups, canned tuna, processed meats and hot dogs, energy bars, baked goods and many other processed foods. Soy also is a common ingredient in Asian cuisine and is sometimes contained in chicken nuggets, low-fat peanut butter, alternative nut butters and even vodka.

People with a soy allergy should not consume soy milk, soy yogurt or ice cream, edamame, miso, tempeh and tofu. Most individuals allergic to soy can safely consume highly refined soybean oil.

Ask your allergist about avoiding this ingredient. People with a soy allergy often can eat foods that contain soy lecithin — a mixture of fatty substances derived from soybean processing.

If you have a soy allergy, ask your allergist if soy lecithin is safe for you. People with a soy allergy sometimes wonder if they should also avoid peanuts — another legume that is a common allergy trigger.

Soybeans also are unrelated to tree nuts such as almonds, walnuts and cashews. Those allergic to soy are no more likely to be allergic to tree nuts or peanuts than they would be to another food. Talk to an allergist to take control of your soy allergy and live the life you want.

Epinephrine is the first-line treatment for anaphylaxis, a severe whole-body allergic reaction that causes symptoms, including tightening of the airway. Anaphylaxis can occur within seconds or minutes of exposure to the allergen, can worsen quickly, and can be deadly. Once a food allergy diagnosis is made, your allergist likely will prescribe an epinephrine auto-injector and teach you how to use it.

Check the expiration date of your auto-injector, note the expiration date on your calendar and ask your pharmacy about reminder services for prescription renewals. Be sure to have two doses available, as the severe reaction may recur. Epinephrine should be used immediately if you experience severe symptoms such as shortness of breath, repetitive coughing, weak pulse, generalized hives, tightness in the throat, trouble breathing or swallowing, or a combination of symptoms from different body areas such as hives, rashes or swelling on the skin coupled with vomiting, diarrhea or abdominal pain.

Repeated doses of epinephrine may be necessary. If you are uncertain whether a reaction warrants epinephrine, use it right away, because the benefits of epinephrine far outweigh the risk that a dose may not have been necessary. Common side effects of epinephrine may include transient anxiety, restlessness, dizziness and shakiness.

Rarely, the medication can lead to an abnormal heart rate or rhythm, a heart attack, a sharp increase in blood pressure and fluid buildup in the lungs, but these adverse effects are generally caused by errors in dosing which is unlikely to occur with use of epinephrine autoinjectors. Patients with certain pre-existing conditions who may be at higher risk for adverse effects should speak to their allergist about epinephrine use.

Your allergist will provide you with a written emergency treatment plan that outlines which medications should be administered and when note that between 10 and 20 percent of life-threatening severe allergic reactions have no skin symptoms.

Be sure you understand how to properly and promptly use an epinephrine auto-injector. Once epinephrine has been administered, immediately call and inform the dispatcher that epinephrine was given and that more may be needed from the emergency responders.

Other medications, such as antihistamine and corticosteroids, may be prescribed to treat mild symptoms of a food allergy, but it is important to note that there is no substitute for epinephrine — this is the only medication that can reverse the life-threatening symptoms of anaphylaxis.

If your child has been prescribed an auto-injector, be sure that you and those responsible for supervising your child understand how to use it. Home Allergies Allergic Conditions Food Allergy Soy. Soy If you get a rash, stomach ache or stuffy or runny nose after eating asian food or drinking soy milk, you may be allergic to soy.

On this page. Overview A member of the legume family, soy is a common ingredient in infant formulas and many other processed foods.

Common Triggers of a Soy Allergy Soy and soy products including some infant formulas , soy milk and soy sauce Soy Allergy Management Avoid products containing soy. This includes reading labels carefully. Always be prepared to treat an allergic reaction because reactions are unpredictable in severity and can occur anywhere.

Products that are covered by the FDA labeling laws and contain soy lecithin as an ingredient must be labeled to state that they contain soy. Highly refined soy or soybean oil will not be labeled as a major allergen on an ingredient statement.

There are clinical studies showing that people with a food allergy can eat highly refined oils. This is because highly refined oils contain extremely small levels of allergenic protein.

However, people with soy allergy need to avoid any expeller pressed, extruded, or cold-pressed soy oil. These types of oil do contain soy protein and must be listed on the label as an allergen. Soy lecithin contains a small amount of soy protein. For this reason, products containing soy lecithin will label those foods for the presence of soy.

The amount of soy protein in soy lecithin is low enough that it usually does not result in an allergic reaction in most people allergic to soy. If you have questions about whether or not you should avoid soy lecithin and soy oil, talk with your allergist. Cross-reactivity occurs when the proteins in one food are similar to the proteins in another.

Soy is a legume. The legume family includes different beans, including peanuts, peas, and lentils. A common question that comes up for people with an allergy to one legume is whether they can eat other legumes.

They also contain thiamin, riboflavin, iron, phosphorus, magnesium, calcium, zinc, and vitamin B6. Unless your child consumes large portions of soy, the small amounts of soy in processed foods do not supply a significant amount of these nutrients.

A soy-restricted diet will not pose any nutritional risk if your child is eating a variety of fruits, vegetables, enriched and fortified grains, and tolerated sources of protein.

Some infants and toddlers develop food intolerances or allergies. Soy is a common food babies can react to. If they are breastfed, they may or may not react to food proteins the mother eats that passes through her breast milk. Formula-fed infants with soy allergy may not tolerate the food proteins such as milk or soy in infant and toddler formulas.

There are several formula options available for young children with food allergies. Soy is a common ingredient in foods in the US.

Whole soy beans edamame can be replaced with other beans fava, garbanzo. Learn more about using soy substitutes.. Search for soy-free recipes. Currently, there are no FDA-approved treatments for soy allergy as of December The best way to prevent soy allergy reactions is to avoid wheat completely.

But some research is being done on soy allergy treatments, such as oral immunotherapy OIT. Many doctors have been offering OIT treatment using foods in various forms, such as a liquid, flour, or the actual food itself.

These methods are not approved by the FDA. The FDA is looking at other food allergy treatments to fast track through the approval process to address this unmet need in the food allergy community. There are many known side effects or possible adverse reactions to OIT. Talk with your allergist to see if this treatment might be right for your child and family.

Also give it right away if the symptoms involve two different parts of the body, like hives with vomiting.

Then call and take your child to the emergency room. Your child needs to be under medical supervision because even if the worst seems to have passed, a second wave of serious symptoms can happen. Sometimes allergists recommend also carrying over-the-counter OTC antihistamines , as these can help treat mild allergy symptoms.

Use an antihistamine after — not as a replacement for — the epinephrine shot during a life-threatening reaction. If your child has a soy allergy, help them avoid eating anything that has soy in it. Read food labels carefully because ingredients can change, and soy can be found in unexpected places.

Some foods look OK from the ingredient list, but while being made they can come in contact with soy. This is called cross-contamination. Look for advisory statements such as "May contain soy," "Processed in a facility that also processes soy," or "Manufactured on equipment also used for soy.

Also, tell the people preparing or serving your child's food about the soy allergy. Sometimes, you may want to bring food with you that you know is safe. Don't eat at the restaurant if the chef, manager, or owner seems uncomfortable with your request for a safe meal.

Discuss symptoms and treatment options with your doctor. Call if breathing becomes difficult. If you are allergic to soy, the only way to prevent an allergic reaction is to avoid soybeans and all soy products.

At the end of this article, we share more soy-based foods, including whole food sources to avoid if you have an allergy or sensitivity to soy. Alternatively you can try a at home-to-laboratory allergy test kit to accurately test whether an allergy exists. When soy sensitivity is suspected you can also use an at-home soy sensitivity test.

At-home tests, which are typically blood tests, provide an accurate way to pinpoint a soy sensitivity. A skin-prick test is used to test for soy allergy not soy sensitivity. This Skin tes t is more common in a clinical setting, a medical professional will prick your skin and expose your skin to small amounts of soy protein.

If hives, irritation, or raised bump breaks out at the test site on your skin, an allergy can be diagnosed. When visiting a medical professional for allergy testing, your GP or allergists will likely ask you several questions about the history of symptoms. Soy is found in several types of foods, and in many cases, it’s not always easy to detect.

Even if you have a mild soy intolerance symptoms, it’s good to be aware of the variety of soy-containing foods. Soy is prevalent in many processed and prepared foods, which can make detecting such products less obvious. Here is a list of foods where soy may be found but difficult to detect:.

Soy can even be found in foods like canned tuna, low-fat peanut butter, and various cooking oils. However, a soy allergy can develop at any age. A soy allergy may be to blame if you experience stomach problems, itching, a repetitive cough, or hives after eating soy-based foods. While soy is generally considered safe to consume, people with soy allergies should avoid it.

This article will help you identify products that contain soy, recognize soy allergy symptoms, and learn what to do if you or someone you care for has an allergic reaction to soy.

If you have a soy allergy, any product containing soy or soy derivatives, which are ingredients obtained from processing soybeans, can cause symptoms.

Soy and soy derivatives can be found in the following:. Soy allergy reactions can affect various organs and body systems, including your digestive and respiratory systems and your skin. In rare cases, people with severe soy allergies experience anaphylaxis.

Rarely a soy allergy will cause anaphylaxis. This dangerous, potentially life-threatening reaction causes impaired breathing and a sudden drop in blood pressure which can send the body into shock.

Symptoms may begin similarly to milder reactions but worsen within seconds or minutes of ingesting an allergen. Additional symptoms of anaphylaxis include:. If you or someone you care for is experiencing an anaphylactic reaction, administer epinephrine using an auto-injector EpiPen and call immediately.

Inform the dispatcher that epinephrine was given and more may be needed. Some people with a soy allergy experience symptoms affecting their digestive system, specifically their GI tract. While most GI symptoms are uncomfortable, some may indicate a severe allergic reaction.

Examples of GI symptoms include the following:. Similar to GI symptoms, respiratory symptoms can range from mild to severe. Respiratory symptoms of a soy allergy can include:. Soy allergies may also produce skin-related symptoms, including the following:.

A food allergy differs from a food intolerance. A person with food intolerance may get digestive symptoms like gas and bloating, whereas those with an allergy have an immune response to allergens in specific foods. A person with a food allergy can develop severe symptoms like trouble breathing, rashes, and, sometimes bu rarely, anaphylaxis.

Treatment for soy allergy symptoms and reactions varies depending on the body system affected and symptom severity. Anaphylaxis can occur within seconds or minutes of ingesting the allergen. The medication should be administered immediately if you experience severe symptoms, including shortness of breath, repetitive coughing, weak pulse, all-over hives, tightness in the throat, trouble breathing or swallowing, or a combination of symptoms from different areas of the body.

For anaphylaxis, administer epinephrine and call immediately. Some of the treatments used for less severe but uncomfortable allergic reactions are:. The natural history of soy allergy.
