Many children suffer from food allergies – which occur when the body’s immune system is stimulated against certain proteins – or from food sensitivities, which cause similar symptoms but do not involve an immune response. Most kids will grow out of these problems by the time they reach five years old, particularly when the allergy is tied to dairy products, wheat or soy. Unfortunately, however, allergies that tend to cause some of the most severe and potentially life-threatening symptoms – including allergies to shellfish and peanuts – are not as easy to shake. In any case, it is important to seek medical assistance to identify any food allergy when one is suspected – even if the reaction is fairly mild. This is because subsequent exposures to some allergens can prompt a much more serious reaction. The most commonly diagnosed food allergies are those to milk, eggs and peanuts, followed by wheat, soy and tree nuts. Treatment of these conditions ranges from trigger avoidance strategies to antihistamine medications, Epi-pen emergency injections and clinical trials.
