What Is A Food Allergy?
An allergy is an immune system response to an otherwise harmless food or food component, usually a protein. The body reacts by flooding the system with histamines and other chemicals to fight off what is perceived as an invader in the body.
Food allergies are rare. According to the National Institute of Allergy and Infectious Diseases (NIAID), about 4 percent of American adults and about 5 percent of American children have a food allergy. Allergies can be caused by more than 170 foods, but nearly 90 percent of food allergies are caused by milk, eggs, peanuts, tree nuts (almonds, walnuts, pecans, cashews, pistachios, etc.), fish, shellfish, wheat and soy.
While children outgrow most food allergies; only about 20 percent of people “outgrow” a peanut allergy.
It is important to consult a board-certified allergist if you suspect you have a food allergy. Allergists can accurately diagnose the allergy and prescribe medication for its treatment. The only completely accurate means of diagnosing a food allergy continues to be a blind food challenge which should only be done by a board-certified allergist in a controlled environment.
Can Peanut Allergies Be Prevented?
Yes. Research shows that introducing peanut foods to infants reduces their likelihood of developing a peanut allergy. Guidelines from the National Institute of Allergy and Infectious Diseases recommends that parents introduce infant-appropriate peanut foods starting as early as 4-6 months, depending on their risk for developing a peanut allergy. Discuss questions about food allergies and introducing peanut foods with your pediatrician.

Do Bans Reduce the Risk of Accidental Exposure?
No. In schools, research has shown that banning peanuts may increase the risk for reactions and does not reduce the frequency of epinephrine use. *
For the restaurant industry, best practices include using basic food safety techniques, separating allergens, clearly labeling allergens and avoiding cross contact in kitchens and serving areas. Allergic individuals should notify staff of their food allergy when dining out and be prepared in case of an accidental ingestion.
The good news is common household cleaners will effectively wash away peanut proteins from surfaces. Simple soap and water (but NOT hand sanitizers) will effectively wash peanut proteins from skin.
