Soy Allergy Diet

The only proven treatment for a person with food allergies is to avoid all of the food(s) that cause
an allergic reaction. Soy allergy is one of the top 8 food allergies in the United States.

The treatment for soy allergy is to remove all soy protein from the diet. Food labels must be
carefully read, as soybeans are used in a large number of commercial foods. Also, products that
contain soy are becoming more widespread. Soybeans are used in making flours, milks, nuts,
and oils. The soybeans may be powdered, granulated, textured, and coarsely or finely ground.

The Food Allergen and Consumer Protection Act of 2004 require that goods must list ingredients
by their common names for the top 8 allergenic foods. The top 8 allergenic foods in the United
States are eggs, milk, soy, wheat, peanuts, tree nuts, fish, and shellfish. However, it is still very
important to read labels of all food purchased and avoid forms of soy protein.

Label ingredients which may show the presence of soy protein.

Examples of soy used in foods
▪ Asian cuisine, including Chinese, Japanese, Thai, Lao, and Korean often contains soy.
▪ Hamburgers and veggie burgers served at some restaurants, fast food chains, and school
lunch programs often contain soy protein.
▪ Veggie burgers and meat substitutes, such as Boca®, Garden®, and Morningstar Farms®
products contain soy protein.
▪ Prepackaged meatloaves and meats with stuffing may contain soy.
▪ Prefried products, purchased in the store or served at a restaurant, are often fried in vegetable
oils that have previously been used to fry foods containing soybean flour or soybean protein.
▪ Soybean flour is often mixed with other flours in commercial products.
▪ Fortified texturized soybeans are often used in vegetarian dishes.
▪ Tofu is made from soybean curd.
▪ The Japanese product “miso” is a paste made from crushed soy, rice, barley, or plum, mixed
with salt and water, and then fermented.
▪ “Natto” is barley miso with ginger added.

Substitutions and Tips
▪ Lecithin, a type of fat, is mostly derived from either soybeans or eggs. If the lecithin is fairly
pure, there is little chance it will contain any soy protein. Lecithin is an emulsifying agent
used in many bakery products, and mixes, and is sold as a liquid or spray for oiling cooking
pans. Manufacturers are not required to list the source of the lecithin on the label of their
products. Often they change the source of the lecithin from egg yolk to soy. It depends on
what is economical at the time.
▪ It is unlikely that a person allergic to soy protein will react to soy oil.

In cooking, you can use substitutes for soybean products
▪ Soy flour – use wheat, rice, oat, barley, or potato flour.
▪ Soybean milk – use cow’s milk, rice or potato milk or any formula that does not contain soy.
▪ Soy miso – use barley, plum or rice miso.
▪ Soy sauce – use pure concentrated beef or chicken broth or flavored salts.

Tips to Follow to Prevent an Allergic Reaction:
▪ Avoid foods that cause a reaction. Sometimes just touching foods can cause a severe
▪ Read the ingredients lists on food labels to make sure allergy-causing foods are present.
Read the list even if you have had the product before. Ingredients may change.
▪ If you are traveling, bring along some of your own special foods.
▪ When eating out, always ask restaurant staff about ingredients in food and how it was
prepared. Ask about oils and the foods fried in them to avoid cross contamination.
▪ Contact food companies if you are unsure of any ingredient on the label.
▪ For infants, elemental formulas or formulas with altered protein should prevent food
reactions. Discuss the various formula options with your doctor or dietitian. Do not assume
products labeled “hypoallergenic” will not cause a reaction.
