Soy Free Diet

Disclaimer: This fact sheet is for education purposes only. Please consult with your doctor or other health professional to make sure this information is right for your child.

Soya beans are used widely in the manufacture of processed foods although they are not commonly eaten in Australia. It is important to know where to look for soy in foods by reading food labels carefully. Check the ingredient list for the word soy.

Avoid foods which contain:

  • Soya beans
  • Soy flour
  • Soy milk & soy milk products eg. soy yoghurts, soy cheeses, soy desserts, soy icecream
  • Soy bean sprouts
  • Edamame
  • Tofu, soy bean curd
  • Fermented products such as:
    • miso (soy bean paste)
    • tamari
    • tempeh
    • bean curd
    • soy sauce
    • teriyaki
    • soy protein isolate

Foods that sometimes (but not always) contain soy include:


  • "Allergy" breads or flours
  • Baby cereals
  • Bread (soy flour is used in most commercial breads)
  • Bread crumbs
  • Breakfast cereals
  • Cakes and biscuits
  • Cake and pancake mixes
  • Canned or jar baby foods
  • Chocolate flavourings
  • Chocolates and sweets
  • Crumbed meats, fish
  • Deli meats and salads
  • Gelati
  • Home made bread mixes
  • Flavourings
  • Flavoured milk drinks
  • Infant formula made from soy
  • Mayonnaise type dressings
  • Meat substitutes
  • Packaged sauces and gravy mixes
  • Sauces and soup mixes
  • Sausages, sausage rolls, frankfurts, pizza
  • Stock cubes
  • Taco shells
  • Textured/Hydrolysed vegetable protein (TVP, HVP), labels must state if it is from soy
  • Unlabelled processed foods eg. takeaway food
  • Vegetarian foods

Note:

There is no need to avoid soy lecithin No 322. Research studies show that most people with soy allergy can safely eat soy lecithin and soyabean oil.

Soy Free Bread Alternatives

Most breads are made with a starter containing soy. This can make avoiding soy very difficult to do. Options for soy free breads are:

  • Home-made using a breadmaker and allowed flours
  • Check your local baker, greengrocer, delicatessen or supermarket for soy free breads
  • Crumpets
  • Many flat breads eg Lebanese or Indian bread, wraps, mountain breads
