If you have a confirmed peanut allergy diagnosis, you should avoid peanuts in all forms, including anything containing traces of peanut in it. Obvious sources include roasted, dry roasted, salted, or plain peanuts and peanut butter. But peanuts can be a hidden ingredient in many foods—this is why it’s important to read the label or ask before buying or eating foods. Ingredients in packaged foods can change at any time without warning.

More than 10 percent of patients with peanut or tree nut allergy report experiencing reactions in restaurants or other food establishments. Because of their common use of peanuts, Asian restaurants, ice cream parlors, and bakeries are considered high-risk for people with a peanut allergy. Even if you order a peanut-free item, there is the possibility of cross-contamination.

Peanuts can be found in many foods and drinks, including:

• Marzipan;
• Nougat;
• Sweets like pudding and hot chocolate;
• African, Asian and Mexican dishes;
• Glazes and marinades;
• Sauces;
• Foods that contain extruded, Cold-pressed, or expelled peanut oil;
• Baked goods like pastries and cookies;
• Candy including chocolates;
• Chili;
• Some vegetarian foods.
