Answer:
Consumption of a specific food or ingredient. In people with food allergies, the immune system mistakenly identifies certain proteins in food as harmful and triggers an immune response, which can cause symptoms such as itching, hives, difficulty breathing, abdominal pain, and in severe cases, anaphylaxis. Food allergies can be caused by a variety of foods, including peanuts, tree nuts, milk, eggs, soy, wheat, fish, and shellfish. It is important for people with food allergies to avoid the foods to which they are allergic and to carry emergency medication in case of accidental exposure.
