The nut problem is mostly a peanut problem
In China, when people say “nut allergy,” what lands them in trouble is almost always the peanut. Peanuts (花生) are not a tree nut, but in Chinese kitchens they behave like one: peanut oil is a common frying medium, crushed peanuts are the default garnish on noodles and cold dishes, and peanut sauce backs a whole category of 凉拌 (cold dressed) plates. I’ve watched a “plain” vegetable noodle arrive buried in a spoonful of ground peanut because that’s just how the cook finishes it. If you react to peanuts, China demands more vigilance than almost any Western country I’ve visited.
Tree nuts (坚果) such as cashew (腰果), almond (杏仁), and walnut (核桃) are less everywhere but still show up in desserts, some braises, and festive pastries. The two need different watch-lists, and I’ll keep them separate below.
Where peanuts hide
Peanut oil
Many restaurants fry in peanut oil because it’s cheap and stable at high heat. This is the silent risk: even a dish with no visible peanuts can trigger a reaction if cooked in that oil. Asking “no peanut” doesn’t remove the oil already in the wok. For a severe allergy, this pushes you toward steamed dishes and places that can confirm a different oil.
Crushed peanut garnish
Dan dan noodles, cold sesame-noodle salads, some soups, and street snacks get a final scatter of crushed peanut. It looks optional; it usually isn’t, or it’s mixed in.
Kung pao and friends
Gongbao chicken (宫保鸡丁) is built around peanuts. So are several Sichuan dishes. Skip the whole category rather than pick them out; the sauce is infused.
Peanut sauce and dips
Hot-pot dips, satay-style sauces, and some dumpling accompaniments use peanut or a peanut-sesame blend. Ask before you dunk.
Tree nuts to watch
Cashews appear in some stir-fries and mixed “deluxe” vegetable plates. Almonds turn up in almond milk (杏仁露, a sweet canned drink), almond tofu (杏仁豆腐) dessert, and some soups. Walnuts show in baked goods and a few northern sweets. Mooncakes and eight-treasure congee (八宝粥) can contain a mix of nuts and seeds, so read before eating festive foods.
Your written defense
| Allergen | Characters to show | Pinyin |
|---|---|---|
| Peanut | 花生 | huasheng |
| Tree nuts | 坚果 | jianguo |
| Cashew | 腰果 | yaoguo |
| Almond | 杏仁 | xingren |
| Walnut | 核桃 | hetao |
Add the line: “我对花生和坚果严重过敏，请换油、换锅，不要加花生酱。” (I am severely allergic to peanut and tree nuts; please change the oil and pan and add no peanut sauce.) Show it, don’t just say it. The broader food allergies in China guide has the full card and phrases, and the reading a Chinese menu piece helps you spot the characters on boards.
Safer ways to eat
Plain steamed rice, mantou, and simply steamed greens with confirmed clear oil are your baseline. Western chains like KFC and McDonald’s publish allergen info in China and are a fallback, though fried items share oil so read the local leaflet. Hotel Chinese restaurants with English-speaking staff are the most controllable. The Chinese vegetarian food tradition doesn’t remove the nut risk, since peanut oil is used regardless of meat, so don’t assume veg means safe.
Cross-contamination reality
Small restaurants use one wok, one cutting board, and one oil for everything. Even if your dish has no nuts listed, traces are likely. If your reaction is severe, this alone may rule out street stalls and hole-in-the-wall spots. Larger kitchens with separate stations are safer but not guaranteed. I’d rather you skip a tempting stall than gamble on a shared wok.
Ordering with confidence
The mechanics matter. Point at the dish, show the card, and confirm. The ordering in Chinese restaurants guide walks through the tick-sheet menus and how to flag a problem before it’s cooked. If the waiter looks unsure, leave; a confident “no” from you is better than a hopeful “yes” from them.
Emergencies and meds
Carry your epinephrine auto-injector in your carry-on, not checked luggage, and know 医院 (hospital) and 救护车 (ambulance). Major city hospitals stock epinephrine; the food safety in China overview points to practical clinic choices. Travel insurance that covers evacuation is wise for a severe allergy, and you should note your allergy in English and Chinese on your phone lock screen.
Reading labels and packaged foods
When you fall back on supermarkets, labels become your defense. Chinese packaged food lists allergens, but the print is small and the terms differ: 花生 for peanut, 坚果 for tree nuts, and 可能含有 (may contain) warnings for cross-contact. Imported items from Europe or Japan often carry clearer English, and the Hema (盒马) and Ole’ chains stock these. Avoid anything with vague “spice blend” or “flavor” listings unless you can confirm, and skip the loose snacks at markets where no label exists. Almond milk (杏仁露) is canned and clearly labeled, so it’s easy to avoid; the bigger surprise is how often “vegetable” crackers or “healthy” bars quietly contain peanut flour for protein.
Documents, insurance, and peace of mind
Beyond the card, put your allergy in English and Chinese on your phone lock screen and in your wallet, and carry a written emergency plan: which hospital, which drug, who to call. Travel insurance that covers allergy emergencies and evacuation is worth the few dollars for a severe case, and you should confirm it before you leave, not after a reaction. Tell your embassy registration about the allergy if it’s severe, so consular help is faster in a crisis. None of this is scare-mongering; China is entirely visitable with a nut allergy, but the shared-wok reality means you prepare once and relax after. The travelers who get into trouble are the ones who assumed “no peanuts, thanks” was enough, and it almost never is.
A script for the table
When you sit down, the order of operations matters. First, before anyone takes your order, show the card and say the key phrase: 我对花生和坚果严重过敏 (I am severely allergic to peanut and tree nuts). Second, point at what you want and confirm no peanut oil and no sauce. Third, if the waiter hesitates or calls a manager, wait for a clear yes before you relax; a vague nod is not consent. I’ve found that framing it as 严重 (severe) rather than just 过敏 (allergic) changes how seriously they take it, because the word signals emergency rather than preference. At a busy stall this takes thirty seconds and prevents the most common mistake, which is assuming the kitchen heard you over the noise. Repeat the script at every stop, even at a place you liked yesterday, because staff and oil change daily. The travelers who manage a nut allergy well in China are the ones who treat the script as routine rather than a special request, who show the card without apology and confirm the oil without embarrassment. The country is entirely visitable this way, and most kitchens, once they understand the severity, will genuinely try to help. The risk comes from the moments you let politeness override clarity, not from the food itself. Keep the script short, keep it written, and keep it repeated, and a nut allergy becomes a manageable detail of the trip rather than its defining anxiety, which is exactly where you want it.
Quick facts
- Peanut oil is a common frying medium; “no peanut” doesn’t remove it from the wok.
- Crushed peanuts garnish noodles, cold dishes, and many soups by default.
- Gongbao chicken and similar Sichuan dishes are peanut-built; skip them.
- Tree nuts appear in almond drinks, mooncakes, and some “deluxe” veg plates.
- Small kitchens share one wok and oil, so cross-contamination is likely.
- Show a written card with 花生 and 坚果; speech alone fails.
- Carry epinephrine in carry-on and know 医院 (hospital).
FAQ
Is it safe to eat at street stalls?
For a mild peanut sensitivity, maybe, if you can see and confirm ingredients. For a severe allergy, no: shared oil and surfaces make it too risky.
Can I trust “no peanuts, please”?
Only as a starting point. Confirm the oil and any sauce separately, because the garnish is the visible part and the oil is the invisible one.
Are Western fast-food chains safe?
More predictable; they publish allergen info in China. But fried items share oil, so check the local leaflet rather than assuming.
What about airplane meals?
Chinese carriers offer special meals if ordered ahead, but nut-free isn’t guaranteed due to shared galleys. Bring safe snacks for the flight.
Do mooncakes and festival foods have nuts?
Often yes, including seeds and almonds. Read the ingredient list or avoid them during Mid-Autumn if your allergy is serious.
Is tree-nut allergy as risky as peanut here?
Less ubiquitous, but cashews and almonds show up in sweets and some dishes. The cross-contamination risk is the same in small kitchens.
What should I tell my hotel?
Give them the written card at breakfast buffets and ask about the oil. Hotels with international standards are most likely to accommodate.
Planning around the allergy
