Food Allergy Myths
Medical Author: Melissa Conrad Stöppler, MD

Food allergies are often misunderstood, even though societal recognition of, and education about, the condition is increasing. See if you have heard – or believed – any of the following myths about food allergies:
1."You're "allergic" to any food that gives you problems." This statement is false, since there are several problems that can arise after eating specific foods, the majority of which are unrelated to allergy. True allergies to foods are immunologic reactions involving the class of immunoglobulins (proteins that assist in the body's immune response) known as immunoglobulin (Ig) E. Other kinds of reactions to foods that are not food allergies include food intolerances (such as lactose or milk intolerance ), food poisoning, and toxic reactions. The prevalence of food allergy in the population is much lower than the prevalence of adverse reactions to foods. It is estimated that true food allergies occur in 2-5% of the population.
2. "All food allergies in children resolve as they get older." As they grow older, some children may tolerate foods that previously caused allergic reactions. This is more likely to happen in the case of allergies to milk, eggs, and wheat, in which the severity of reactions (or symptoms) may decrease by late childhood. It is not clear in all cases, however, if the improved symptoms are an indication that the allergy has disappeared. For example, in wheat allergy (celiac disease) symptoms may improve, but a mild allergic reaction continues in the intestine, and symptoms and signs of the allergy may recur in later years. On the other hand, milk allergy appears to truly disappear as children grow older.
interesting I though =)
