A peanut allergy in Thailand is not the same challenge as a peanut allergy in Scandinavia. In Bangkok, ground peanuts hide in curry pastes, pad thai, and som tam. In Stockholm, nuts are labeled on every menu by law. Traveling with food allergies or restrictions requires destination-specific preparation, not just a generic card that says "I am allergic." With the right tools and knowledge, you can eat adventurously and safely anywhere.
Allergy Translation Cards and Restaurant Communication
Print allergy cards in the local language before every country. Equal Eats (USD 8-12 per language) and SelectWisely (USD 7 per card) make laminated cards that kitchen staff actually understand because they use local food terminology, not Google Translate output. For Thailand, your card needs to specify "no peanuts, no tree nuts, no peanut oil, no ground peanut garnish" in Thai because simply saying "mai sai thua" (no beans) does not cover crushed peanuts added as garnish. Show the card to the cook, not the waiter. Walk past the counter and hand it directly to whoever is preparing food. In Japan, restaurant staff take allergies extremely seriously and will consult with the chef if you present a card in Japanese. In Vietnam and Cambodia, allergy awareness is lower, so stick to dishes you can visually verify: grilled meats, pho without additions, and steamed rice. For celiac travelers, Southeast Asia is surprisingly manageable because rice replaces wheat in most dishes. The danger zones are soy sauce (contains wheat) in Japanese and Chinese cooking, and the fish sauce brands in Vietnam that add wheat starch. Carry a dedicated soy sauce alternative (tamari packets weigh nothing) for shared hostel cooking.

Carry two EpiPens in separate bags: one in your daypack and one in your main bag. EpiPens survive temperatures up to 25 degrees Celsius, so in tropical countries store them in an insulated pouch (FRIO wallet, USD 22) that keeps them cool through evaporation for 45 hours without electricity. Get a doctor's letter in English explaining your condition and medications for border crossings where carrying injectable devices raises questions. Register your allergy with your travel insurance provider before departure so claims processing is faster. For nut allergies, the safest cuisines are Japanese (minimal nut use), Mexican (rare in traditional cooking), and Ethiopian (injera is nut-free). The highest-risk cuisines are Thai, Indonesian (satay sauce), Indian (ground cashew in curries), and West African (groundnut stew). Vegan travelers find the easiest time in India (40% of the population is vegetarian, and menus mark veg dishes with a green dot), Taiwan (Buddhist vegetarian restaurants are everywhere), and Israel (vegan capital of the world with 400+ dedicated restaurants in Tel Aviv alone). The hardest destinations for vegans are Argentina, Mongolia, and rural Eastern Europe where meat-free meals barely exist outside major cities.
