The truth about food allergies
A food allergy is defined as a medical condition in which exposure to a certain food triggers a harmful immune response.

The symptoms of an allergic reaction usually occur within minutes after food consumption or exposure. While most food allergies result in mild symptoms, sometimes the reactions can severe and life threatening. Symptoms of an allergic reaction include swelling or itching of the lips, tongue or mouth, itching or tightness in the throat, wheezing or difficulty breathing, hives, vomiting, cramps or diarrhea. If you notice a child having symptoms, stop them from eating the food immediately, evaluate the need for emergency treatment, and seek medical attention.
