Living With a Soy Allergy

If all you needed to do for a soy allergy was skip the soy sauce and tofu, life would be a breeze! But soybeans are a big part of processed foods, too.

Keep this cheat sheet handy to protect yourself or your child from an allergic reaction.

3 Ways to Play It Safe

Always read labels. In the U.S., "soy" must be listed on the label if it’s in a food.

Be careful about eating at Asian restaurants. Even if you order a soy-free dish, you could still be exposed because the ingredient is used so often in Asian cooking. A cook might use the same utensil on soy and non-soy dishes. Explain that you need to be sure your food doesn’t touch soy in any way.

Ask your doctor about soy oil and lecithin. Most people with soy allergies can handle highly refined soy oil. The same goes for soy lecithin, which is often used in chocolate candy, peanut butter, and margarine. Avoid cold-pressed, expelled or extruded soy oil—sometimes called gourmet oils. These ingredients are different and are not safe to eat if allergic to soy. Your doctor or an allergist can help you figure out which are OK for you.
