Food Allergies & Food Intolerance
A Answers (3)
Food allergies can be dangerous if IgE antibodies have been produced in response to a particular food protein. A person might not have a reaction upon the very first exposure to the allergen; however subsequent exposures can become increasingly more severe due to the immune system's ability to recognize the allergen more quickly each time. This may lead to anaphylaxis (a system-wide reaction in the body that occurs within minutes to 2 hours after ingestion of the food) causing respiratory and cardiovascular issues. If a person is at risk for an anaphylactic reaction to food, it is important to keep an epi-pen in close reach and share a plan of action with people around you or your child (caregivers, teachers, school nurse, etc.). You can download a free action plan from the Food Allergy and Anaphylaxis Network (www.foodallergy.org).
