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.

How to read a label for a soy-free diet:

Be sure to avoid giving your child foods that contain any of the following ingredients:
  • hydrolyzed soy protein
  • miso
  • shoyo sauce
  • soy flour
  • soy grits
  • soy nuts
  • soy milk
  • soy sprouts
  • soy protein concentrate
  • soy protein isolate
  • soy sauce
  • tempeh
  • textured vegetable protein (TVP)
  • tofu

Other possible sources of soy or soy products:

  • flavorings
  • hydrolyzed plant protein
  • hydrolyzed vegetable protein
  • natural flavoring
  • vegetable broth
  • vegetable gum
  • vegetable starch

To avoid soy and soy products:

  • Contact the manufacture to identify the natural flavorings in foods. Ask if they use soy as a carrier protein for the natural flavoring.

  • Flavorings may be soy based.

  • Hydrolyzed plant and hydrolyzed vegetable protein in the US are likely to be soy.

  • Contact the company to identify vegetable broth, gums, and starches, as they have the potential to be soy.
