Peanut Allergy Diet

General guidelines for peanut allergy

The key to an allergy-free diet is to stay away from all foods or products containing the food to which you are allergic. If you are allergic to peanuts, you will need to stay away from peanuts and foods that contain peanuts. You will need to read all food labels.

How to read a label for a peanut-free diet

The Food Allergen Labeling and Consumer Protection Act (FALCPA) is a law that requires U.S. packaged foods to state clearly on the label if they contain peanuts. In addition to peanuts, stay away from foods with any of these ingredients:

  • Artificial nuts

  • Beer nuts

  • Ground nuts

  • Mixed nuts

  • Monkey nuts

  • Peanut butter

  • Peanut flour

  • Peanut oil

Foods that may contain peanuts

These foods may also contain peanuts:

  • African, Chinese, Mexican, Thai, and other ethnic dishes

  • Baked goods

  • Candy

  • Cereals

  • Chili, spaghetti sauce

  • Crackers

  • Egg rolls

  • Enchilada sauce

  • Flavoring (natural and artificial) 

  • Hydrolyzed plant protein

  • Hydrolyzed vegetable protein

  • Ice creams, frozen yogurts, and nondairy frozen desserts

  • Marzipan

  • Nougat

Always read the entire ingredient label to look for peanuts. Peanut may be in the ingredient list. Or it could be listed in a “Contains: peanut” statement after the ingredient list.

Other sources of peanuts

These food sources may also contain peanuts:

  • Peanut oil that is cold-pressed, extruded, or expeller-expressed. But studies show that most people with allergies can safely eat foods containing highly refined peanut oil.

  • Ethnic foods, commercially prepared baked goods, and candy. These can be cross-contaminated with peanuts since peanuts are often used in these types of foods.

  • Homemade chili and spaghetti sauce. These may be thickened with peanut butter or peanut flour.

  • Hydrolyzed plant and vegetable protein in imported foods. These proteins may be from peanuts. In the U.S., these proteins often come from soy.

Important points

Foods that don't contain peanuts could be contaminated during manufacturing. Advisory statements are not regulated by the FDA. They are voluntary. These include labels such as "processed in a facility that also processed peanut." Or "made on shared equipment." Ask your healthcare provider if you can eat products with these labels. Or if you should stay away from them.

Some foods and products are not covered by the FALCPA law. These include:

  • Foods that are not regulated by the FDA

  • Cosmetics and personal care items

  • Prescription and over-the-counter medicines and supplements

  • Toys, crafts, and pet foods

When you are eating out

  • Always carry 2 epinephrine auto-injectors. Make sure you and those close to you know how to use it.

  • Wear a medical alert bracelet or necklace with your allergy information.

  • If you don't have epinephrine auto-injectors, talk with your healthcare provider. Ask if you should carry them.

  • In a restaurant, food may be cross-contaminated with peanuts.

  • Always read food labels. And always ask about ingredients at restaurants. Do this even if these are foods that you have eaten in the past.

  • Stay away from buffets with peanuts. This will help you avoid cross-contamination of foods with shared utensils.


A medicine is now available to treat peanut allergy in children. The FDA-approved medicine is for children and teens ages 4 to 17. A child with a confirmed peanut allergy can start taking the medicine at age 4. Talk with your child’s healthcare provider to find out if this medicine can help your child. If your child is taking this medicine, continue to make sure they don’t eat any peanuts or peanut products.
