Soy Allergy:  Common Food Allergies

Many children with cow's milk allergy also have a soy allergy. For that reason soy formulas are not always the best option for milk allergic children.

Once a diagnosis is made, a diet completely free of soy must be followed. Although this may seem easy, it is an ingredient used in many processed foods, baked goods, baking mixes, cereals and soups.

Symptoms of Soy Allergy

An allergy to soy can cause symptoms such as:

  • Asthma,
  • Stuffy nose
  • Hives
  • Tissue swelling
  • Gastrointestinal problems

As mentioned above, an estimated 30-50% of babies allergic to cow’s milk protein also develop an allergy to soy when given a soy based formula.

It can also cause eczema in children, and in infants the allergy can cause loose stool and diarrhea, abdominal discomfort, irritability, crying, intestinal blood loss, anemia and failure to thrive.   Respiratory symptoms include cough, asthma, wheezing and rhinitis.
