Food Allergy : A food allergy is an abnormal immune response to certain proteins in food. When someone with a food allergy consumes even a small amount of the triggering food, their immune system mistakenly identifies the protein as harmful and overreacts, leading to a range of symptoms. These reactions can vary from mild to severe and, in some cases, can be life-threatening. Common Food Allergens 1. Milk 2. Eggs 3. Peanuts 4. Tree nuts (e.g., almonds, walnuts, cashews) 5. Fish 6.
