immune system overreacts to harmless food proteins
Food allergies, also known as food hypersensitivity, occur when the immune system mistakenly identifies a harmless food protein as a threat and triggers an allergic reaction. This can lead to symptoms ranging from mild (such as hives or itching) to severe (such as anaphylaxis, which can be life-threatening). Common allergens include peanuts, tree nuts, milk, eggs, wheat, soy, fish, and shellfish.
