Risk factors

Certain factors may put you at greater risk of developing a soy allergy:

• Family history. You're at increased risk of allergy to soy or other foods if other allergies, such as hay fever, asthma, hives or eczema, are common in your family.
• Age. Soy allergy is most common in children, especially toddlers and infants.
• Other allergies. In some cases, people who are allergic to wheat, beans (legumes), milk or other foods can also have an allergic reaction to soy. Also, people who are allergic to soy may have test results showing allergy to other legumes, but may be able to eat them with no problem.

If you're not nursing, ask your doctor for advice on what to feed your child until your appointment to reduce the risk of symptoms.

If you have symptoms of soy allergy, avoid foods that contain soy.
