What is a Soy Allergy

Published on Sunday, 24 June 2012 12:28

Soy is a legume and can be found in multiple forms such as soybean, soy flour, soy oil, soy seasoning, and soy protein. Soy is a common “hidden” food additive. This allergy mostly occurs during infancy and is usually outgrown by age 5. Soy allergy is less severe than other allergies but in rare cases it can cause a severe reaction called anaphylaxis.

There are some soy products that do not cause a reaction or may only produce a small reaction.  For example, fermented soy may be tolerable to eat for people because the process of fermentation breaks down the proteins in soy. Soybean oil contains only small amounts of the soy protein and doesn’t normally create a reaction.
