Soy allergy: causes and treatment

Allergies come in different shapes and sizes. One person has a very serious allergy to a certain substance and the other fortunately only suffers from a mild allergy. Just like many other products, soy also contains proteins that different people can be allergic to. Soya is processed in many different products. You can usually read on the product packaging whether or not soy has been used in the product.

Children and soy allergy

In children, a cow’s milk protein allergy is often discovered at a young age, and soy milk is often prescribed as an alternative to cow’s milk. This is no longer done nowadays, because there is a good chance that a soy allergy will develop. If children have a cow’s milk protein allergy, allergen-free milk such as Nutramigen is recommended.

The symptoms of a soy allergy

If you are allergic to soya and still come into contact with it, you will experience an allergic reaction that may cause various symptoms. An example of a common symptom of a soy allergy is acne or a rash. The throat can also swell, making breathing a lot more difficult and asthmatic symptoms are also a common symptom. If you inhale soy powder, it may not be a food allergy, but it can still cause breathing problems. It has been proven that most patients can still eat soy products without experiencing these symptoms. Other common symptoms of a soy allergy include:

  • fever
  • diarrhea
  • conjunctivitis
  • eczema
  • itch
  • hypotension
  • vomit
  • pollinosis
  • angioedema
  • dermatitis

Soy allergy; the diagnose

A soy allergy only exists when there is a clear link between soy and the allergic reactions. Soy is invisibly processed in many products, making recording this link very difficult. So if you really want to be sure that it is a soy allergy, it is advisable to have an allergy test carried out. Because soy has the same allergens as birch pollen, peanuts and other legumes, it is possible that there is cross-reactivity.

Preventing a soy allergy

An allergic reaction to soy can be treated, but prevention is of course better than treatment. Nowadays, however, soy is widely used in all kinds of products. For example, soy flour is used to bake bread, cookies and pastries, there is soy milk, soy oil, soy flakes and so on. It is therefore very important that you are well informed in advance about the products that cannot be eaten because they contain soy. So only buy products that do not contain soy. This must be stated on all products that contain soy or that are made in an environment where soy is also used. If you are not sure what you can and cannot eat with a soy allergy, you can always consult your doctor.
