Soy Allergy | One of the 14 Food Allergens

14 Major Food Allergens: Soya

Soya (soy) is classed as one of the 14 major food allergens under government legislation. Therefore businesses must clearly identify soy as an ingredient on all food ingredient labels for sale within the UK.

Soya is a legume and is found in many foods. According to AllergyUK, it is found in 60% of manufactured foods. Soy comes from soybeans, which can be consumed as beans, soy sauce or oil, or soy flour, which is widely used in baked foods like bread and biscuits. Therefore, it is classed as one of the most common food allergies. Immature soybeans are known as edamame. 

The level of avoidance of soy will differ for each individual. Some people may be able to consume some types of soy, such as soy sauce, due to the minimal amount of soy in the product, while others may need to avoid all kinds of soy.

Those with soy allergies may also test positive for being allergic to other legumes in the family, such as kidney beans, broad beans, chickpeas, peanuts, peas, lentils, black-eyed peas, lima beans, and butter beans.


Soy Allergy Symptoms

It can cause various symptoms common with allergies, such as eczema, nausea, abdominal pain, and in some rare cases, anaphylaxis.

Soy Allergy: the foods to avoid

Those with soy allergies should avoid certain products, and food businesses are required by Food Laws to label when there is soy included in the product. Below is a list of some ingredients containing soy:

  • Soy products: soy flour, soy protein, soya yoghurt, soya-based cheese, soy beans, soy nuts, soya milk, soy oil, soy sauce
  • Tofu 
  • Vegetable broth
  • Vegetarian burgers, sausage rolls, and many other meat substitutes
  • Miso
  • Gluten-free bread (which comes in lots of varieties)

Soy Lecithin Allergy

Lecithin is a food additive used as an emulsifier in food to improve shelf-life, texture, and binds some foods, such as cocoa and cocoa butter in chocolate. Soy Lecithin contains traces of soy protein, although it is tolerable for most people with soya/soy allergies as it contains very little soy.
