Soy Allergy Diet

 

General guidelines for soy allergy:

The key to an allergy-free diet is to avoid giving your child the foods or products containing the food he/she is allergic to. The items that your child is allergic to are called allergens.
 
A soy allergy is an abnormal response of the body to the proteins found in soy. Soybeans are classified as a legume. Other foods in the legume family are navy, kidney, string, black, and pinto beans, chickpeas (garbanzo beans), lentils, carob, licorice, and peanuts. Sensitivity to peanuts is the most common, but soybean sensitivity is also prevalent. Sensitivity to one legume can often be in association with sensitivity to another legume.
