The only treatment for someone with food allergies is to avoid all of the food that causes 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. You must read food labels with care, as soybeans are used in a large number of store-bought foods.

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.

US food companies are required to 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.

Read the labels of all store-bought food to avoid forms of soy protein.

Most people who are allergic to soy may safely eat soybean oil (not cold pressed, expeller processed or extruded oil) and soy lecithin. Ask your doctor or dietitian if you need to avoid these.

  • Premade meatloaves and meats with stuffing may contain soy.

  • Pre-fried products, purchased in the store or served at a restaurant, are often fried in vegetable oils that have been used to fry foods that contain soybean flour or soybean protein.

  • Soybean flour is often mixed with other flours in store bought products.

Substitutions and Tips

Lecithin, a type of fat, is mostly made from either soybeans or eggs. If the lecithin is fairly pure, there is little chance it will contain any soy protein. Lecithin is sold as a liquid or spray for oiling cooking pans. Food makers 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 is unlikely that soy oil will cause you to react.

Soy Substitutes for Cooking

  • 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 Prevent an Allergic Reaction

  • Avoid foods that cause a reaction. Sometimes just touching foods can cause a severe reaction.

  • Read the ingredients lists on food labels to make sure the food doesn’t contain soy. Read the list even if you have had the product before. Ingredients may change.

  • When you travel bring along some of your own foods.

  • When you eat 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 formula options with your doctor or dietitian. Do not assume products labeled “hypoallergenic” will not cause a reaction.
