Common Allergens in Chinese Cooking: The Key Risks
Peanuts (花生 / huāshēng)
Peanuts are one of the most significant allergen risks in Chinese cooking. They appear:
- In cooking oil (花生油 peanut oil is commonly used for stir-frying)
- As crushed toppings on noodle dishes, salads and cold dishes
- In sauces (particularly in Sichuan, Shandong and Cantonese cooking)
- In desserts and pastries
High-risk dishes: Kung Pao Chicken (宫保鸡丁 — almost always contains peanuts), many cold appetisers (凉菜), Dan Dan Noodles (担担面), Shaanxi cold noodles (凉皮)
Chinese allergy card phrase: “我对花生严重过敏，包括花生油。请确保我的食物中完全没有花生和花生产品。” (I have a severe peanut allergy, including peanut oil. Please ensure my food contains no peanuts or peanut products.)
Tree Nuts (坚果 / jiānguǒ)
Walnuts (核桃), cashews (腰果), almonds (杏仁) and pine nuts (松子) appear frequently in:
- Stir-fried dishes, particularly in northern and Sichuan cooking
- Pastries and cakes
- Cold dishes and salads
Shellfish and Seafood (海鲜 / hǎixiān, 贝壳类 / bèiké lèi)
Shellfish allergy is extremely dangerous in coastal Chinese cities where shellfish-based stocks are widely used:
- Shrimp paste (虾酱) is used as a flavoring base in many dishes
- Oyster sauce (蚝油) is extremely common in Chinese cooking; used even in dishes with no obvious seafood
- Dried shrimp (干虾) and dried scallop (干贝) are used as flavoring in soups and sauces
The hidden danger: Dishes that don’t appear to contain seafood can contain shrimp paste, oyster sauce or dried shrimp as flavoring agents. Always specify clearly.
Wheat and Gluten (小麦 / xiǎomài, 麸质 / fū zhì)
China has extensive wheat-based cuisine, particularly in the north:
- Noodles (面条), dumplings (饺子), steamed buns (包子/馒头), flatbreads
- Soy sauce (酱油) usually contains wheat as a fermentation ingredient
- Many stir-fried dishes use a flour or cornstarch coating
- Hoisin sauce (海鲜酱) contains wheat
Gluten-free options: Rice-based dishes from southern China are generally safer. Rice noodles (米粉), rice congee (粥), steamed rice dishes, and dishes specifically from Cantonese or Fujian cooking using rice rather than wheat.
Soy (大豆 / dàdòu)
Soy is pervasive in Chinese cooking:
- Soy sauce is used in virtually all savory cooking
- Tofu (豆腐) and various soy products appear throughout
- Soybean oil (大豆油) is a common cooking oil
A severe soy allergy makes eating at standard Chinese restaurants very difficult. Focus on cuisines that use fish sauce rather than soy sauce (some Yunnan minority dishes) and rice-based preparations.
Sesame (芝麻 / zhīma)
Sesame oil (芝麻油) is used as a finishing flavoring in many dishes; sesame seeds appear on pastries and breads; sesame paste (芝麻酱) is a dipping sauce for hot pot and a dressing for noodles.
Vegetarian and Vegan Dining
The “Vegetarian” Complication
In Chinese, there are two relevant terms:
- 素食 (sùshí): Can mean both vegetarian and vegan; traditionally Buddhist vegetarianism excludes all animal products including eggs and dairy
- 不吃肉 (bù chī ròu): “Don’t eat meat” — but this often doesn’t prevent fish or eggs
The challenge: Many Chinese people don’t consider fish (鱼) or seafood to be “meat.” When you say you’re vegetarian, fish may still be offered or used in stocks.
Be specific: Say “我吃素，不吃肉、鱼、虾、贝壳等所有动物产品” (I eat vegetarian; I don’t eat meat, fish, shrimp, shellfish or any animal products).
Buddhist Vegetarian Restaurants (素斋)
The best solution for vegetarians in China is Buddhist vegetarian restaurants (素斋馆, sù zhāi guǎn). These:
- Are found near all major Buddhist temples and in many city centers
- Use no meat, fish, eggs, dairy, or in the strictest tradition, no “pungent vegetables” (onion, garlic, leek, scallion, shallot)
- Often produce remarkably creative dishes using tofu, gluten (seitan) and vegetables
- Are typically very affordable (¥30–¥80 per person for a good spread)
- Have menus that are entirely safe for strict vegans
Restaurant Phrases for Vegetarians
“我是素食者，不吃任何肉类、海鲜、鱼类和动物产品。” (I am vegetarian; I don’t eat any meat, seafood, fish or animal products.)
“这道菜里有肉汤或者鸡汤吗？” (Does this dish contain meat stock or chicken stock?)
“有没有纯素食选择？” (Are there vegan options?)
Vegetarian-Friendly Cuisines in China
Best for vegetarians:
- Cantonese dim sum (many vegetable dumplings, steamed rice dishes)
- Buddhist temple restaurants everywhere
- Yunnan cuisine (many vegetable-forward dishes, wood ear mushrooms, wild herbs)
- Shanxi-style wheat dishes (plain steamed buns, braised noodles without meat)
Most difficult:
- Sichuan hot pot (stock typically contains beef bones)
- Most Dongbei (northeastern China) home cooking
- Standard canteen food (饭堂) — everything shares woks with meat
Halal Dining (清真 / Qīngzhēn)
China has a substantial Muslim population (approximately 25 million), primarily in Xinjiang, Ningxia, Gansu and Qinghai, with significant Hui Muslim communities in most major cities.
Finding Halal Food
Certified halal restaurants display the 清真 (qīngzhēn) sign, typically in Arabic-styled calligraphy or with the Arabic word “حلال”. These establishments serve only halal-certified meat, use no pork and maintain halal standards throughout.
In Xinjiang, Ningxia and Qinghai: Halal food is the dominant standard throughout these regions; finding non-halal food requires effort.
In major cities: Every major city has a Hui Muslim restaurant district or clear halal restaurant options. Search for “清真餐厅” on the Dianping app.
Hotel restaurants: Major international hotel restaurants are usually able to accommodate halal requests with advance notice.
Dishes to Be Aware Of
- Pork (猪肉 zhūròu) is pervasive in standard Chinese cooking — it appears in dumplings, wonton soup, fried rice, and as an assumed protein in many vegetable dishes
- Lard (猪油 zhūyóu) is used for cooking in traditional Chinese restaurants in some regions
- Standard soy sauce fermentation may involve non-halal processes
Safe categories:
- Any restaurant displaying 清真 certification
- Muslim Quarter restaurants in Xi’an, Xining, Yinchuan
- Xinjiang restaurants throughout China (the lamb skewer shops are nearly universally halal)
Lactose Intolerance
Lactose intolerance is extremely common among Chinese people and standard Chinese cooking uses almost no dairy. Butter, cream and cheese are essentially absent from traditional Chinese cuisine.
Exceptions: Some northwestern and Inner Mongolian dishes use dairy (milk tea, yogurt, dried milk products). These are usually obvious from context.
Risk: Western-style bakeries and international chain restaurants in major cities do use dairy. Check labels at supermarkets.
Creating Allergy Cards
Allergy Cards China is a service (allergycard.com) that produces professionally translated laminated allergy cards in Chinese for common allergies. These are small laminated cards you hand to servers or kitchen staff. They communicate your allergy in clear, unambiguous Chinese.
Alternatively: Create your own. The key requirements for an effective allergy card:
- Clear statement of the allergen in Chinese characters AND pinyin
- Statement of severity (“severe allergy” — 严重过敏)
- Specific list of foods and cooking ingredients to avoid
- Request to check with the kitchen
Useful free resource: The Equal Eats website (equaleats.com) provides free downloadable Chinese allergy cards for common allergens.
Practical Safety Strategies
Carry Your Medication
If you have anaphylactic allergy risk, carry your EpiPen (epinephrine autoinjector) in your hand baggage at all times. Note: EpiPens may be difficult to replace in China — bring sufficient supply for your entire trip plus backup.
Chinese translation of your medical condition: If you carry an EpiPen, have a Chinese-language card explaining that you may need an injection in an emergency.
Communicate at the Time of Ordering (Not Just at Arrival)
With severe allergies, communicate when ordering AND when the dish arrives. Chinese restaurant kitchens process many orders simultaneously and may not reliably communicate allergy information through the order system.
Choose Restaurants with Transparent Kitchens
Open-kitchen restaurant concepts (increasingly common in Chinese cities) allow some visibility into food preparation. This doesn’t solve the allergen problem but allows for somewhat better monitoring.
Simpler Dishes Are Safer
Dishes with fewer ingredients and simpler preparation carry lower allergen risk. A bowl of plain rice congee (白粥) or steamed rice with a simply prepared vegetable dish is safer than a complex sauce-heavy preparation.
Final Word
China is manageable for people with food allergies and dietary restrictions — but it requires preparation. Download the allergy card for your specific needs, carry your medication, learn the key Chinese vocabulary for your restrictions, and use Buddhist vegetarian restaurants as your safety fallback throughout the trip.
The cuisine is too varied and excellent to avoid entirely; with the right tools, most dietary needs can be accommodated.
