The key to an allergy-free diet is to avoid all foods or products containing the food to which you are allergic. 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 one legume can often be in association with sensitivity to another legume.
The Food Allergen Labeling and Consumer Protection Act of 2004 requires U.S. manufacturers of packaged food items to state clearly on the label if it contains soy or a soy-based ingredient.
