Soy

Soy causes allergic reactions much less frequently than its cousin the peanut. Avoidance of soy products however is much more difficulty. Soy has become a major part of processed food products in our country.

Nutrients Provided by Soy

Soy contributes the following nutrients:

  • Thiamin
  • Riboflavin
  • Vitamin B6
  • Folacin
  • Calcium
  • Phosphorus
  • Magnesium
  • Iron
  • Zinc

Soy alone is not major dietary contributors, but because it is in so many products, excluding all those foods can cause an unbalanced diet.

Avoid Products and Ingredients Containing Soy


Soy is listed as follows on labels:

  • Soy flour
  • Soy protein
  • Soy protein isolate
  • Textured vegetable protein (TVP)
  • Tofu
  • Miso
  • Soy nuts
  • Soy sauce

Ingredients That May Contain Soy Protein

  • Vegetable starch
  • Vegetable broth
  • Vegetable gum
  • Soybean oil - In the processing of most soybean oils, the protein portion which causes allergic reaction is removed. Therefore, like peanut oil, it is believed that those with soybean sensitivity can have soybean oil and soy lecithin. If, however, your allergic symptoms continue or get worse, eliminate all soy products.

Products Containing Soy and Soy Protein

  • Infant formulas
  • Cereals
  • Baked goods
  • Crackers
  • Canned tuna
  • Soups
  • Sauces
