Why Peanut + Tree Nut Is the Most Important Dual-Allergy Card

Peanut allergy and tree nut allergy are the two most common severe food allergies in adults, and they frequently co-occur. While peanuts are technically legumes (not tree nuts), many people with peanut allergy are also allergic to one or more tree nuts — including almonds, cashews, walnuts, pistachios, and hazelnuts.

The challenge for travelers is that these two allergy groups appear in very different cuisines and in different forms. Peanuts dominate Asian cooking (Thai pad thai, Chinese sauces, Indonesian satay). Tree nuts appear in Middle Eastern sweets (baklava, halva), French and Italian pastries (marzipan, frangipane, pesto), and Indian curries (cashew and almond-based sauces).

A combined peanut and tree nut allergy card that clearly lists both groups — with their local-language names — is the safest solution for world travelers with nut allergies.

Where Nut Allergies Hide Around the World

Asian cuisine: peanuts everywhere

Peanuts appear as garnish, oil, and sauce base in Thai, Chinese, Vietnamese, and Indonesian cooking. Many dishes contain peanut oil without listing it as an ingredient.

European pastries: tree nuts in every layer

French macarons, Italian pesto, German marzipan, and Middle Eastern baklava all contain almonds, hazelnuts, or pistachios. Often used in flours and spreads rather than whole nuts.

Indian cuisine: cashews and almonds in sauces

Korma, butter chicken, and many other Indian curry bases use ground cashews or almonds for creaminess. The nuts are blended in and invisible in the finished dish.

Cross-contamination is the hidden risk

Shared fryers, cutting boards, and cooking oils spread nut proteins across dishes that don't list nuts as ingredients. Your card explicitly requests clean equipment.

Frequently Asked Questions

Are peanuts and tree nuts the same thing?

No. Peanuts are legumes (in the same family as beans and lentils). Tree nuts are a separate food group that includes almonds, cashews, walnuts, pistachios, hazelnuts, Brazil nuts, and pecans. Many people are allergic to both, but they are distinct allergies. Our card covers both groups with their specific names in the target language.

Which countries are most dangerous for combined nut allergies?

Thailand and China (peanuts in nearly every dish), France and Italy (tree nuts in pastries and sauces), India (cashews and almonds in curry sauces), and Middle Eastern countries (pistachios and walnuts in sweets) carry the highest risk.

Does the card mention peanut oil specifically?

Yes. Our cards explicitly mention both whole peanuts and peanut oil (groundnut oil) in the target language, since many food-service workers do not realize peanut oil is derived from peanuts and can trigger reactions.

Should I also note a sesame allergy on the same card?

If you have a sesame allergy in addition to nut allergies, add sesame to your selection. Sesame is now regulated as a major allergen in the US and appears frequently in Asian and Middle Eastern cuisine alongside nuts.
