Allergy (Allergies)

In What We Ingest

Foods and medications can also cause allergic reactions, some of which can be very severe. These reactions often start with localized tingling or itching and then may lead to rash or additional symptoms, such as swelling, nausea, vomiting, diarrhea, or difficulty breathing. The two most common allergens that are ingested are:

  • Foods: The most common food allergens are cow's milk, eggs, peanuts, tree nuts, wheat, soy, shellfish, finned fish, and sesame. Cow's milk, egg, wheat, and soy are most common in children, and are often outgrown over time. The most common allergens in adults are peanut, tree nuts, and shellfish.
  • Medications: Although any medication can cause an allergic reaction, common examples include antibiotics (such as penicillin), and anti-inflammatory agents, such as aspirin and ibuprofen.
