Soy Allergy, From Symptoms to Treatment
Soybean is one type of legume that is widely used to make various kinds of food. Its products are often consumed as daily food, some of which are soy milk, tofu, and tempeh.
Unfortunately, there are some people who have allergies to this one ingredient. What is a soy allergic reaction like and how can you deal with it?
What makes a person allergic to soy?
Soy allergy is one type of food allergy that often occurs, especially in infants and children. Often times, allergies are developed from infancy by reactions to soy-based formulas.
Broadly speaking, an allergic reaction can occur due to an excessive response from the immune system when exposed to an allergen, the name for a substance from food that triggers a reaction.
In people who have this allergy, the immune system mistakenly identifies a protein in soy as a dangerous threat. That's why the body produces antibodies called immunoglobulin E (IgE) which send signals to release histamine and other chemicals in the bloodstream.
The release of histamine also fights soy protein, causing various reactions such as itching, tingling sensations around the mouth, or other symptoms.
Keep in mind, there are several factors that make a person more at risk of developing a soy allergy. These factors include family history, age, and other allergies.
If you or your child has family members who have allergies, the risk of getting them is higher. Food allergies are also more prone to occur in children, especially infants and toddlers. Also, you can develop sensitivity to soy if you have allergies to other foods.
However, soy allergies that occur in childhood usually disappear with age. Those of you who have a soy allergy will not necessarily experience a reaction if you eat other types of legumes.
Symptoms that can appear when an allergic reaction occurs
Allergic rhinitis or hay fever is a type of rhinitis (inflammation of the nasal membrane) that occurs when you inhale an allergen. This is the body's overreaction to allergens. Symptoms of a food allergy due to soy are generally only mild symptoms. Usually, the reaction will occur within a few minutes to several hours after consuming the allergen food. The various symptoms include:
In rare cases, soy allergies can also cause more severe symptoms. This symptom, often called anaphylactic shock, is very dangerous because it can be life-threatening. Some of the signs are:
How do you deal with soy allergies?
If you are worried that you might have allergies, then all you have to do is check with your doctor to get a diagnosis. Especially when reactions have occurred several times after consuming soybeans.
During the examination, the doctor will ask about the symptoms you feel, such as the symptoms that appear, what foods you ate before when the symptoms occurred, and for how long you had them. Your doctor may also ask you and your family's medical history to find out if there is any possibility of hereditary allergies.
Next, you will have to undergo some further food allergy tests to confirm the presence of allergies with an allergen exposure test through a skin prick or blood test to measure how many antibodies are in the body.
After you are diagnosed with a soy allergy, your doctor may give you a drug in the form of an antihistamine. Antihistamines are not drugs to relieve allergies, but they can relieve symptoms whenever an allergic reaction occurs.
Some of the antihistamines you can buy at the pharmacy include diphenhydramine, cetirizine, and loratadine. When you accidentally eat foods that contain soy, take this medicine immediately to reduce symptoms.
If your allergies are worse, your doctor will give you medicine in the form of an auto-injection of epinephrine. Whenever you experience symptoms of a severe allergic reaction or anaphylactic shock, you should immediately get an injection of epinephrine in the area of your upper thigh. After that, seek medical attention immediately and don't wait for your symptoms to subside.
Prevent allergic reactions by not eating foods containing soy
Preventing food allergies by staying away from soy products is still the best way. Indeed, avoiding soy foods is very difficult because this ingredient is often used in various products and daily cooking.
To help you, all you have to do is read the information label about the composition of the ingredients listed on the package. Sometimes soy is also found in unexpected foods like canned meat and soups. Therefore, reading the composition of the ingredients is very important.
Here are foods that you should avoid consuming other than soybeans themselves.
Sometimes there are some foods that contain soy lecithin and refined soybean oil (not oils that use flavors). In products such as chocolate coatings and margarine, lecithin is often used to provide a more even and consistent texture.
Foods that contain lecithin are said to be safe for some soy allergy patients because of their very low protein content. However, you still have to consult a doctor before consuming it so that there are no unwanted reactions.
