The allergist may also recommend an oral food challenge. Emergency medication and emergency equipment will be on hand during this procedure in case you have a severe reaction. Peanut is one of eight allergens with specific labeling requirements under the Food Allergen Labeling and Consumer Protection Act of Under that law, manufacturers of packaged food products that contain peanut as an ingredient that are sold in the U.
To avoid the risk of anaphylactic shock , people with a peanut allergy should be very careful about what they eat. Peanuts and peanut products may be found in candies, cereals and baked goods such as cookies, cakes and pies.
Be extra careful when eating Asian and Mexican food and other cuisines in which peanuts are commonly used. Even ice cream parlors may be a source for accidental exposures, since peanuts are a common topping. It may be a good idea to discuss with your allergist the risks of consuming products with voluntary labeling. Keep in mind that these products may be manufactured in a facility that also processes peanuts — so check the label carefully and contact the manufacturer with any questions.
Many individuals with an allergy to peanuts can safely consume foods made with highly refined peanut oil, which has been purified, refined, bleached and deodorized to remove the peanut protein from the oil. Unrefined peanut oil — often characterized as extruded, cold-pressed, aromatic, gourmet, expelled or expeller-pressed — still contains peanut protein and should be avoided.
If you have a peanut allergy, ask your allergist whether you should avoid all types of peanut oil. While some people report symptoms such as skin rashes or chest tightness when they are near to or smell peanut butter, a placebo-controlled trial of children exposed to open peanut butter containers documented no systemic reactions.
Still, food particles containing peanut proteins can become airborne during the grinding or pulverization of peanuts, and inhaling peanut protein in this type of situation could cause an allergic reaction.
In addition, odors may cause conditioned physical responses, such as anxiety, a skin rash or a change in blood pressure. In , the National Institute for Allergy and Infectious Disease NIAID issued new updated guidelines in order to define high, moderate and low-risk infants for developing peanut allergy.
The guidelines also address how to proceed with introduction of peanut based on risk in order to prevent the development of peanut allergy.
The updated guidelines are a breakthrough for the prevention of peanut allergy. Peanut allergy has become much more common in recent years, and there is now a roadmap to prevent many new cases. The guidelines recommend introduction of peanut-containing foods as early as months for high-risk infants who have already started solid foods, after determining that it is safe to do so.
If your child is determined to be high risk, the guidelines recommend having them tested for peanut allergy. Your allergist may do this with a skin test or blood test.
Depending on the results, they may recommend attempting to try peanut for the first time in the office. However, if the skin test reaction is large 8 mm or larger the guidelines recommend not pursuing an oral challenge, as the infant is likely already allergic at that point. Therefore, an allergist may decide not to have the child try peanut at all if they have a very large reaction to the skin test.
In some cases, mild symptoms occur before you develop severe symptoms. Pay close attention to your body and be prepared to use your epinephrine auto-injector and get medical help if your reaction becomes severe. They can help determine what caused your symptoms. You can then learn how to avoid and treat allergic reactions in the future. When you have a peanut allergy, the only way to avoid an allergic reaction is to stay away from all foods with peanuts.
Reading ingredient lists and asking questions about food is a necessary part of avoiding peanuts and an allergic reaction. Ask restaurants, bakeries, and other food providers about peanuts that may be in the food.
Also, ask about food that may be prepared near peanuts. If you have a peanut allergy, always have epinephrine auto-injectors with you. Consider wearing a medical alert bracelet with your allergy information. If you have an allergy to peanuts, you may be at risk for delayed anaphylaxis. Here are the symptoms to watch for and preventative measures to take. An expert panel with the FDA voted for the approval of a new treatment option for children with peanut allergies.
