Important Things to Know About Peanut Allergies

Peanut allergy is one of the most common food allergies.  Peanuts can cause a severe, potentially fatal, allergic anaphylaxis reaction.  It is advised that those with peanut allergy have quick access to an epinephrine auto-injector such as an EpiPen.  To prevent a reaction, strict avoidance of peanut and peanut products is essential.  It is advised to routinely read ingredient labels to identify peanut ingredients.

An allergy to peanuts appear to be on the rise in children.  According to FARE-funded study, the number of children in the U.S. with peanut allergy has more than tripled between 1997 and 2008.

Peanut allergies tend to be life long, although studies indicate that approximately 20% of children with peanut allergy do eventually outgrow their allergy.  Younger siblings of children allergic to peanuts may be at increased risk for allergy to peanuts.  We can advise you regarding testing for siblings.

Peanuts are not the same as tree nuts (almonds, cashews, walnuts, etc.), which grown on trees.  Peanuts grow underground and are part of a different plant family, the legumes.  Other examples of legumes include beans, peas, lentils and soybeans.  If you are allergic to peanuts, you do not have a greater chance of being allergic to another legume (including soy) than you would to any other food.

Even trace amounts of peanut can cause an allergic reaction.  Casual contact with peanuts, such as touching peanuts or peanut butter residue, is less likely to trigger a severe reaction.  Casual contact becomes a concern if the area that comes into contact with peanuts then comes into contact with the eyes, nose or mouth.  An example:  a child with peanut allergy gets peanut butter on her/his fingers, and then rubs their eyes.

The federal Food Allergen Labeling and Consumer Protection Act (FALCPA) requires that all packaged food products sold in the U.S. that contain peanuts as an ingredient must list the work “Peanut” on the label.  As of this time, the use of advisory labels (such as “May Contain”) on packaged foods in voluntary, and there are no guidelines for their use.  However, the FDA has begun to develop a long-term strategy to help manufacturers use these statements in a clear and consistent manner, so threat consumers with food allergies and their caregivers can be informed as to the potential presence of the eight major allergens.
