Yes, food allergies can develop at any age, even in adults who previously tolerated those foods without problems. Adult-onset food allergies affect approximately 10.8% of US adults, with shellfish being the most common trigger, followed by tree nuts and finfish. These new allergies often develop due to changes in immune system function, increased exposure to allergens, or cross-reactivity with environmental allergens like pollen. Adults typically experience more severe reactions than children, with symptoms ranging from mild digestive issues to life-threatening anaphylaxis. If you suspect a new food allergy, keep a detailed food diary and consult an allergist for proper testing and diagnosis.
