Quick Answer
Avoid foods that trigger severe allergic reactions, such as anaphylaxis, in the backcountry. Common culprits include peanuts, tree nuts, fish, shellfish, milk, eggs, wheat, and soy. If you have a known allergy, plan your meals carefully to avoid these foods.
Common Allergenic Foods
Peanuts are a leading cause of anaphylaxis, and even small amounts can trigger a severe reaction. Some people are also allergic to tree nuts, including almonds, walnuts, and cashews. When preparing meals in the backcountry, use peanut-free and tree nut-free oils, such as sunflower or grapeseed oil.
Other Allergenic Foods to Avoid
Fish and shellfish are common allergens, and some people are allergic to both. Milk, eggs, wheat, and soy are also common allergens, especially in processed foods. When shopping for backcountry food, read labels carefully and avoid products with these ingredients.
Prevention and Treatment
If you have a severe food allergy, carry an EpiPen or other epinephrine injector with you at all times. Know how to use it correctly and take it with you on every hike. If you experience symptoms of an allergic reaction, such as hives, itching, swelling, stomach cramps, diarrhea, or difficulty breathing, seek medical attention immediately.
