The only treatment for someone with food allergies is to completely avoid the food they are allergic to. Peanut allergy is one of the top 8 food allergies in the United States.

Peanut allergy can be very dangerous. Peanut protein may be in foods that you don’t expect. Peanuts are often found in Asian foods and candy but may also be in chili, soups, baked goods, marzipan and other sweets. When you eat out, clearly explain your allergy to the manager and wait staff, so the food is not cooked or cross-contaminated with peanuts.

When cooking at home, clean counters, utensils and pans well that have had peanuts in or on them. Cooking with peanuts and removing them does not work because the heat causes peanut protein to seep into the food. For some people who are very allergic, even touching something that had peanuts on it that was not well cleaned will cause a small reaction.

US food manufacturers are required to list ingredients by their common names for the top 8 allergenic foods. The top 8 allergenic foods in the United States are eggs, milk, soy, wheat, peanut, tree nuts, fish, and shellfish.

Read labels each time you shop since the ingredients often change without warning. Check and recheck even the “safe” foods you have bought before.

Avoid all foods that are produced on equipment shared with peanuts or other nuts. There is a risk of cross contamination.

  • Peanuts

  • Peanut flower

Most people with a peanut allergy may safely eat peanut oil (sometimes called Arachis oil), since it does not contain a large amount of protein. But they cannot eat cold pressed, expelled or extruded peanut oil-sometimes referred to as gourmet oils. Talk to your doctor to figure out if you should avoid peanut oil.

Cautions and Tips

  • You should always have medicines with you to stop a serious allergic reaction.

  • Peanuts are not true nuts; they are legumes. Some people also must avoid other foods in the legume family (soybeans, peas, and garbanzo (chickpea) beans.

  • Beware of store-bought nuts. Peanuts, which are de-flavored, re-flavored and pressed, can be sold as imitation almonds, walnuts or other nuts.

  • Seeds and other products are often processed at the same place as peanuts or tree nuts. If you are unsure and the label doesn’t state this, call the food company to be sure. Examples include M & M® candies or Jelly Belly® jelly beans.

Tips to Prevent an Allergic Reaction

  • Avoid foods that cause a reaction. Sometimes just touching foods can cause a reaction. Wash hands often.

  • Read the ingredients lists on food labels to make sure peanuts are not present. Read the list even if you have had the product before. Ingredients may change.

  • When you travel bring along some of your own foods.

  • When you eat out, always ask restaurant staff about ingredients in food and how it was prepared. Cooking oils can have allergens.
