Food Allergies in Taiwan
Communicating at Night Markets
Taiwanese cuisine is built on peanuts, soy, and sesame, none of them optional extras, and much of it is served at night market stalls that cook to order. Getting your allergy across clearly, before you order, is what makes the country manageable.
Why a written card works better than a spoken request
Taiwan's night market culture is warm and food-forward, but a spoken "no peanuts" in English is easy to miss over the noise of a busy stall, particularly where the operator's attention is split between several orders and a shared fryer. A written card removes that ambiguity. It states clearly, in a script the vendor can read without translation, exactly which ingredients need to be avoided, and it signals severity in a way a quick verbal exchange often doesn't.
Taiwan's structural allergens
Unlike a cuisine where an allergen shows up occasionally, Taiwan's street food staples are built around a small set of ingredients used almost everywhere. Peanut powder is the standout: it's a classic topping inside gua bao (braised pork belly buns), sprinkled over oyster vermicelli, and mixed into shaved ice desserts, none of which look like "peanut food" on sight. Soy sauce and soy products (tofu, soy milk) are foundational to nearly every savory dish, and sesame oil is a standard finishing touch on stir-fries and noodle soups.
Taiwan risk at a glance
- Peanut allergy: Critical risk. Peanut powder is a classic topping in gua bao, oyster vermicelli, and shaved ice.
- Soy allergy: High risk. Soy sauce, tofu, and soy milk are used across nearly every savory dish.
- Sesame allergy: High risk. Sesame oil finishes many stir-fries, noodle dishes, and dipping sauces.
- Shellfish allergy: High risk. Oyster omelet is a signature night market dish built structurally around shellfish.
- Gluten/wheat allergy: Moderate to high risk. Beef noodle soup and most dumplings are wheat-based.

Key phrases in Mandarin Chinese
A written card covers the detail, but a few spoken phrases help open the conversation. "Wǒ duì huāshēng guòmǐn" (我對花生過敏, "I'm allergic to peanuts") covers Taiwan's single biggest risk. More generally, "Wǒ yǒu shíwù guòmǐn" (我有食物過敏, "I have a food allergy") signals the request is medical, not a preference. Pointing to the written card while saying either phrase is the most effective combination, especially over the noise of a busy stall.
Night markets and shared cooking equipment
Night market stalls typically serve one or two dishes each, cooked to order in a shared fryer or wok that may carry residue from the previous customer's order. This is a real cross-contact risk for peanut and shellfish allergies in particular, since fryer oil is reused across many dishes in a single evening. Sit-down restaurants and food courts in Taipei that cater to tourists tend to be more flexible about ingredient substitution than a single-dish night market stall, so build in extra caution, not less, once you're at the market.
If something goes wrong
Save Taiwan's emergency numbers before you land: 119 for ambulance and fire, 110 for police, and 112, which works from any mobile phone even without a local SIM. Taipei and Taiwan's other major cities have well-equipped hospitals, though English-speaking staff are more reliably found in larger cities than rural areas.

Frequently asked questions
How do you explain a food allergy in Taiwan?
A written card in Traditional Chinese is the most reliable method. Taiwan uses Traditional Chinese characters, distinct from the Simplified Chinese used in mainland China, so a card written for a China trip won't necessarily read correctly here. Night market stall operators, who cook to order and rarely speak more than functional English, are far more reliably reached with a written card listing your specific allergens than with a spoken request.
Is Taiwan safe for people with food allergies?
Taiwan is manageable for food allergy travelers with preparation, but its night market food culture takes more care than a sit-down restaurant. The main challenge is that peanut powder, soy sauce, and sesame oil are used across dishes that don't read as risky in English, and a single stall's shared fryer or wok can carry allergen residue from a previous order. Restaurants in Taipei that cater to tourists are generally more accommodating than night market stalls, but a written card removes the guesswork either way.
What are the most common food allergens in Taiwanese cooking?
Peanuts are the most structurally present allergen, appearing as crushed peanut powder on gua bao, oyster vermicelli, and shaved ice, not just in obviously peanut-based dishes. Soy sauce, tofu, and soy milk are kitchen staples across nearly every savory dish. Sesame oil is a standard finishing ingredient in stir-fries and noodle soups. Shellfish is structural to the signature oyster omelet, and wheat is the base of beef noodle soup and most dumplings.
Does gua bao contain peanuts?
Traditionally, yes. Crushed peanut powder (or ground peanut candy) is one of the classic toppings inside a gua bao, the braised pork belly bun, alongside pickled mustard greens and cilantro. It's easy to miss because the peanut isn't visually obvious once folded into the bun, so always ask specifically before ordering, since many vendors include it by default.
