Soy allergies are among the less prevalent in the Top 8, with rates as high as 0.7% in some areas and lower or virtually non-existent in others. While many children outgrow their soy allergy by the age of 10, it can also develop at any age with symptoms that vary in severity. For most, exposure to soy may result in mild symptoms such as hives, itching, or digestive discomfort. In extremely rare, severe cases, soy can trigger respiratory issues, swelling, or even anaphylaxis—a life-threatening allergic reaction that requires immediate medical intervention. Given that soy is a common ingredient in many processed foods, often hidden in unexpected places like baked goods, salad dressings, and sauces, careful label-reading is essential.
