Food allergies and dietary restrictions

The severity reality

Severe food allergies are far less commonly known about in China than in Western countries. Anaphylaxis as a recognised medical category is understood in clinical settings, but at a typical restaurant — particularly outside tier-1 cities — staff may interpret 'I am allergic to X' as 'I prefer not to eat X' and act on it accordingly. Cross-contamination awareness is lower. Kitchen practices that Western food-allergy management assumes (separate utensils, separate surfaces, declaring allergens on menus) are not routine in Chinese restaurant kitchens.

If you have a severe allergy with anaphylaxis risk, China is a high-stakes food environment. This does not mean you cannot travel there — but it requires careful planning, the right documentation, and a conservative approach to food choices.

Translation card approach

The single most useful tool for any food allergy in China is a professionally translated allergy card in Chinese. The card should include:

• Your name in English and Chinese pinyin.
• A clear statement: '我对以下食物过敏，如果我吃了这些食物，我会有生命危险' (I am allergic to the following foods. If I eat them, I may die or need emergency treatment.)
• A specific list of the allergens to avoid in Chinese characters.
• The common forms and hidden sources of each allergen.
• A request: '请务必通知厨房，并在上菜前确认不含以上成分' (Please notify the kitchen and confirm these ingredients are not present before serving.)
• Your emergency contact number and the instruction to call 120 (ambulance) if a reaction occurs.

Have this written by a native Chinese speaker — a professional translation service or a Chinese friend fluent in both languages. Do not rely on Google Translate or machine translation for a medical document. Several allergy-card services for China travellers exist online and have been reviewed by Chinese-speaking dietitians.

Common hidden ingredients in Chinese cuisine

Understanding where the major allergens hide in Chinese cooking is essential:

Peanut and tree nuts: peanut oil is a primary cooking oil in many Chinese regional cuisines (Cantonese, Shandong). Peanuts appear in cold-dish dressings (kung pao chicken, dan dan mian, cold cucumber salad), satay-style sauces, street-food condiments, and desserts. Walnut and chestnut appear in northern and Sichuan dishes. The distinction between peanut oil refined to remove protein and cold-pressed peanut oil is important for allergy management — refined peanut oil is often considered safe for peanut-allergic individuals, but this cannot be assumed without specific confirmation.

Sesame: sesame oil (芝麻油, zhīma yóu) finishes noodle dishes, dumplings, and cold-dressed dishes throughout Chinese cooking. Sesame paste (芝麻酱) is in re gan mian noodles, hotpot dipping sauces, and cold-dressed tofu. Hard to avoid; must be specifically excluded.

Soy: soy sauce (酱油) is foundational to virtually all Chinese restaurant cooking. Soy in various forms (tofu, edamame, soy milk, fermented bean paste) appears everywhere. Avoiding soy in a Chinese restaurant setting requires a severely restricted diet or very specific communication.

Wheat / gluten: wheat is the backbone of northern Chinese cuisine — virtually all noodles (except those specifically labelled rice noodles), dumplings, steamed buns, flatbreads, and soy sauces contain wheat. Many dark soy sauces, oyster sauces, and seasoning pastes contain wheat. Southern cuisines (Guangdong, Yunnan, Guangxi) are more rice-based and offer more naturally wheat-free options.

Eggs: in dumpling and pastry doughs, egg-drop soups, fried rice, egg fu yung, stir-fries. Eggs appear across all regional cuisines.

Shellfish: fish sauce (鱼酱, yújiàng) and oyster sauce (蚝油, háoyóu) are widely used — including in dishes that appear to contain only vegetables. Dried shrimp (虾米) is a standard flavour ingredient in stocks, dumplings, and Cantonese cooking. Shrimp paste (虾酱) appears in some Sichuan and Cantonese preparations. Shellfish allergy is one of the harder allergies to manage in Chinese cuisine because shellfish derivatives appear in places where they would not be declared as an ingredient in a Western kitchen.

MSG (味精, wèijīng / monosodium glutamate): widespread in Chinese restaurant cooking. Sensitivity to MSG exists but true MSG allergy (anaphylaxis) is extremely rare. Most 'MSG sensitivity' symptoms described in Western literature have not been confirmed as allergic reactions in controlled studies. If you avoid MSG for preference, ask 不要味精 (bù yào wèijīng); kitchens will often comply.

Pork lard (猪油, zhūyóu): used as a cooking fat, particularly in northern and central China. Present in some contexts where the dish appears to contain only vegetables. Important for those with pork restriction (religious or allergy-based).

Management strategies by allergy type

**Peanut allergy (anaphylaxis risk)**: - Carry your epipen/auto-injector at all times. - Eat primarily at Buddhist vegetarian restaurants (素菜馆) — peanuts appear but in a more controlled context, and the kitchen has no meat/fish to contaminate the space with. - Avoid: cold-dressed dishes (凉菜), kung pao preparations, street stalls with shared oil, buffet settings. - Prefer: international hotel restaurants where allergen management protocols are followed; Japanese or Korean restaurants in China (where peanut oil is not the default); simple steamed or boiled dishes (whole fish, steamed vegetables) with no dressing.

**Shellfish allergy (anaphylaxis risk)**: - Avoid Cantonese cuisine (oyster sauce is endemic). - Muslim/halal (清真) restaurants are safer for shellfish allergies because fish sauce and oyster sauce are not standard in Hui cuisine. - Northern Chinese cuisine (Beijing, Shanxi, Shaanxi) is more lamb-and-pork-dominant with less seafood derivative use. - Specific phrases: 没有虾 (méiyǒu xiā — no shrimp); 没有蚝油 (méiyǒu háoyóu — no oyster sauce); 没有鱼酱 (méiyǒu yújiàng — no fish sauce).

Nut allergy (tree nuts): less universally present than peanuts in Chinese cuisine; appears in specific dishes (walnut porridge, chestnut preparations, pine-nut fried rice). More manageable than peanut allergy, but check for the tree nut types you react to.

Coeliac disease

Coeliac (severe gluten/wheat intolerance with intestinal damage risk) is genuinely challenging in mainland China. Wheat is central to northern Chinese cuisine and appears widely in sauces and condiments in all regional cuisines.

**Safer cuisines within China**: - **Yunnan cuisine**: rice-based; crossing rice noodles (过桥米线), steamed dishes. - **Guangdong/Cantonese**: rice-based when eating at home; restaurant Cantonese uses wheat in soy sauce and oyster sauce, but the base ingredients are often rice. - **Guangxi and Hunan**: rice noodle (米粉) traditions.

**Specific strategies**: - Carry your own gluten-free tamari (wheat-free soy sauce) in a small bottle. - Rice noodles (米粉) and glass noodles (粉丝, made from mung bean starch) are gluten-free. - Steamed plain rice is universally safe. - Avoid: virtually all dumplings (jiaozi, baozi, wonton), all wheat noodles, fried dishes where the batter is wheat, most restaurant sauces.

Lactose intolerance

Traditional Chinese cuisine is dairy-minimal — historical Chinese diets included almost no milk or cheese, and most Chinese adults are lactose intolerant. Standard restaurant cooking does not use dairy. Modern coffee shops, Western-style restaurants, dessert chains, and Hong Kong milk-tea culture do use dairy. Most coffee shops now offer oat, soy, and almond milk alternatives.

Emergency preparation

For severe allergy travel in China: - Research the nearest international hospital to each city you visit (see the emergency numbers guide for city-by-city listings). - Save the number for 120 (ambulance) in your phone. - Make sure your travel insurance covers anaphylaxis treatment and potential medical evacuation. - Have a Chinese-speaking contact who can speak for you in a medical emergency — save their number under an obvious label. - Bring more auto-injectors than you think you need; Chinese pharmacies do not stock Western-brand epinephrine auto-injectors.
