What Are Soy Allergies?

Soy is a food product that is made from soybeans and can be used as an ingredient in foods, such as tofu and soy milk. Soy is also commonly used in the production of many processed foods. Nowadays, it is important to know if your food contains soy. This is because soy allergy is one of the most common food allergies and around 0.3% of the general population suffer from soy-induced  allergies.  

So how do soy allergies happen? Well, soy allergies occurs when our immune systems mistakenly identifies soy proteins as harmful invaders and develops antibodies to fight against them. This forces the body to release histamine which in turn causes you to experience allergic symptoms.

Soy allergy is often confused with soy intolerance because the symptoms can be similar. However, an allergy involves a reaction by your immune system whereas soy intolerance does not involve any immunological response.

The severity of soy allergies varies from one person to another: some people are very sensitive and only need a small amount of soy to experience a reaction, while others can tolerate small amounts without any problems.

Symptoms Of Soy Allergies

Soy allergies are the most common food allergy in infants and children. The symptoms of a soy allergy can vary from person to person, but some common symptoms include:

  • Hives 
  • Itching 
  • Eczema 
  • Swollen lips or tongue 
  • Shortness of breath 
  • Chest tightness or pain 
  • Nausea or vomiting 
  • Diarrhea 
  • Anaphylaxis (a severe allergic reaction that can be life-threatening) 

If you experience any of these symptoms after eating soy-containing foods, seek medical help immediately.

Are There Soy Allergy Diets?

There is no such thing as a "soy allergy diet" instead there are ways to avoid eating soy-rich foods. To keep a soy-free diet, eat foods that contain little or no amount of soy in them. 

You may be wondering how possible it is to stay completely soy-free or avoid eating foods rich in soy. Well, the truth is that it takes a great deal of care and dedication. In the coming sections, we will discuss productive and effective ways of staying soy-free and better alternatives to soy foods. 

Is Allergy Product Labelling Mandatory?

Different food products in a grocery store

To avoid soy in foods and beverages, you will need to read the product labels. In most cases, if a food contains soy or any of its derivatives such as lecithin; it will be labeled as containing "soy" or "soya". However, some products may not list soy on their label but may still contain soy protein.

Food manufacturers are required to list any of the top eight allergens on their product labels. The eight allergens that must be listed are milk, eggs, peanuts, tree nuts, wheat, soybeans, shellfish, and fish. If a product contains one or more of these allergens, the label must list it.

Asides from this, The Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA) also requires that all manufacturers must list the most-common eight allergens on their product list. This law applies to any packaged food regulated by the FDA, which includes most foods sold in supermarkets and convenience stores.

You should note that FALCPA does not apply to restaurants, schools, or other institutions. However, many restaurants voluntarily provide allergen information on their menus so that customers can be aware. 

Also, you should be careful about what you eat when you travel out of the country. In some countries, due to a lack of regulations, soy may not be listed on the label. In these cases, you will need to contact the food manufacturer and inquire about whether or not their product contains soy. 

If you are uncertain about any ingredients or want more clarification, but you cannot reach the food or product manufacturer for some reason, you can always check out our blog posts for the most updated information on healthy foods.
