Eating gluten-free abroad
Gluten is the protein in wheat, rye and barley, and oats are often contaminated with it. Abroad it hides in soy sauce, malt, beer, breadcrumbs, thickened sauces and spice blends, and restaurant rules on declaring it vary widely.

What counts as gluten
Gluten is a group of proteins found in wheat, rye and barley, and in any grain bred from them. That makes the list longer than it looks: spelt, khorasan (sold as Kamut), durum, einkorn, emmer, farro and triticale (a wheat and rye cross) all contain it. So do the foods made from them, including semolina, couscous, bulgur, freekeh and atta, the wholemeal flour used for Indian flatbreads.
Oats are the grey area. They contain avenin, a protein similar to gluten, and Coeliac UK says most people with coeliac disease tolerate uncontaminated oats while a small number don't. The bigger problem is that ordinary oats are often grown and milled alongside wheat, barley and rye. EU and UK law lists oats among the cereals containing gluten. In Australia and New Zealand, a product containing oats can't be labelled gluten-free at all.
It also matters which condition you're managing, because restaurants hear "gluten" and assume one thing:
- Coeliac disease is an autoimmune disease, not an allergy. Gluten from any of the grains above makes the immune system damage the gut, and even small amounts count. Crumbs, shared fryer oil and flour dust matter.
- Wheat allergy is an immune reaction to wheat proteins. It usually starts within minutes and can be life-threatening. Whether barley, rye or oats are a problem for you is a question for your allergist.
- Non-coeliac gluten sensitivity causes similar symptoms to coeliac disease without the gut damage or antibodies.
Gluten turns up under names that don't say wheat. Watch for malt (malted barley, malt extract, malt vinegar), seitan and Chinese miànjīn (wheat gluten made into mock meat), Japanese fu (dried wheat gluten in soups), brewer's yeast, hydrolysed wheat protein, and beer in batters, stews and sauces. Soy sauce is usually brewed with wheat. Compounded asafoetida (hing), the pungent spice in many Indian dals, is sold as a powder cut with flour, and that flour is often wheat.
Where gluten hides on menus
| Cuisine | Watch for |
|---|---|
| Japanese | Soy sauce in almost every sauce and broth; ramen and udon noodles; soba, which is often part wheat; tempura batter; panko on tonkatsu; barley miso (麦味噌 mugi miso); fu in miso soup |
| Chinese | Soy, oyster and hoisin sauces; wheat noodles in dan dan noodles; dumpling wrappers on xiaolongbao; pancakes with Peking duck; mock meats made from wheat gluten |
| Korean | Gochujang and doenjang, which often contain wheat or barley; soy sauce marinades on bulgogi; wheat rice cakes (밀떡 mil-tteok) in some tteokbokki |
| Thai | Soy and oyster sauces in stir-fries such as pad kra pao; egg noodles (บะหมี่ ba mee); battered fried snacks. Rice noodles in pad thai are wheat-free, the sauces may not be |
| Vietnamese | The baguette in banh mi; hoisin served with pho; soy dipping sauces; some fried spring rolls use wheat wrappers |
| Indian | Naan, roti, paratha and puri (atta and maida flour); samosa pastry; hing in dal and tadka; semolina (rava) in some dosas and sweets |
| Arabic and Turkish | Bulgur in tabbouleh and kibbeh; flatbreads with every meal; the dough base of lahmacun; filo in baklava; flour in some falafel mixes |
| Italian | Pasta and pizza, obviously; breadcrumbs on arancini; sponge fingers in tiramisu; flour-dusted meat before frying |
| French and German | Roux-thickened sauces and gravies; croque-monsieur; pastry in quiche lorraine; spätzle; breadcrumbs on schnitzel; beer in sauces |
| Spanish | Breadcrumbs and béchamel in croquetas; traditional gazpacho is thickened with bread |
Cross-contact is where most coeliac reactions in restaurants start. The classic one is the shared fryer: chips or rice crackers fried in the same oil as battered fish or breaded cutlets. Pasta water reused for "gluten-free" pasta, a grill brushed with soy marinade, a toaster, a floury pizza bench, and noodle shops that boil wheat and buckwheat noodles in the same water are all common routes. In bakeries and pizzerias, airborne flour settles on everything.
Labelling rules around the world
EU and UK. "Cereals containing gluten", namely wheat (including spelt and khorasan), rye, barley and oats, are one of the 14 allergens. Packaged food must name the specific cereal in the ingredients and emphasise it, for example in bold. Restaurants and takeaways must also give you the information: across the EU each country decides how, and in the UK it can be verbal if a visible notice tells you to ask. A few highly processed ingredients are exempt, including wheat-based glucose syrups and maltodextrins and cereals used to make spirits.
US. Only wheat is a major food allergen under FALCPA. Barley, rye and oats don't have to be called out, so malt or barley can appear in an ingredient list without a "Contains" warning. "Gluten-free" is a voluntary claim defined by the FDA. The federal allergen law covers packaged food, not restaurant meals made to order.
Australia and New Zealand. Wheat, barley, oats and rye must all be declared, and the allergen summary must use the word "gluten". Restaurant and takeaway food must have this information displayed or available when you ask. A "gluten free" claim here means no detectable gluten and no oats, stricter than the 20 ppm limit used in Europe and North America.
Canada. Wheat and triticale are priority allergens, and barley, oats, rye, triticale and wheat must be declared as gluten sources on prepackaged food. There is no national rule making restaurants tell you.
Japan. Wheat (小麦 komugi) is one of the nine mandatory allergens on packaged food, usually shown as (一部に小麦を含む), "contains wheat in part". Barley and rye aren't on the list, so barley tea and barley miso carry no warning. Restaurants aren't legally required to label allergens.
How to order with coeliac disease or a wheat allergy
- Name the condition, not a preference. "I have coeliac disease, I can't eat any wheat, barley or rye, even a little" gets a different response from "gluten-free, please". With a wheat allergy, say allergy.
- Ask about the hidden ones by name: soy sauce, stock cubes, thickened sauces, malt, beer, flour dusting, and spice blends like hing.
- Ask about the fryer and the pot. Is the oil shared with anything battered or breaded? Is the pasta or noodle water fresh?
- Show it written down. Use the words for gluten and wheat above in the local language, and a translated card that explains crumbs and shared oil count.
- Read "may contain" for what it is. Precautionary warnings are voluntary in most countries, so their absence proves nothing. Japan doesn't allow "may contain" at all and uses a factory statement instead.
- Follow your doctor's plan. If you have a wheat allergy and have been prescribed adrenaline, carry it every time you eat out.
In rice-based cuisines, plain rice, rice noodles and grilled dishes are often the easiest starting points, but the sauce is where the wheat usually is. Confirm every time.

Questions
Is soy sauce gluten-free?
Usually not. Standard soy sauce is brewed with wheat, which makes it unsuitable for people with coeliac disease. Tamari is often made with little or no wheat and gluten-free soy sauces exist, but check the label or ask the kitchen which bottle they use.
Can people with coeliac disease eat oats?
Coeliac UK says most people with coeliac disease can tolerate uncontaminated gluten-free oats, but a small number react to avenin, a protein similar to gluten. Ordinary oats are often contaminated with wheat, barley or rye. In Australia and New Zealand oats can't be labelled gluten-free at all, so follow your own medical team's advice.
Is buckwheat gluten-free?
Buckwheat isn't related to wheat and contains no gluten. The catch is that soba noodles are often made with a share of wheat flour, so a soba dish can contain gluten. Buckwheat is also a serious allergen in its own right in Japan and Korea.
Is beer gluten-free?
Ordinary beer, lager, stout and ale are brewed from barley (sometimes wheat) and are not gluten-free. Gluten-free beers are made, and can only be labelled that way at 20 ppm or less in the UK. Coeliac UK says distilled spirits are gluten-free because gluten doesn't pass through distillation.
What is the difference between coeliac disease and a wheat allergy?
Coeliac disease is an autoimmune disease: gluten from wheat, rye or barley triggers the immune system to damage the gut, and small amounts matter. A wheat allergy is an immune reaction to wheat proteins that usually starts within minutes and can be life-threatening. They need different precautions, so describe the right one to the restaurant.
This guide is general information, not medical advice. Follow the allergy action plan your doctor gave you, and always confirm ingredients with the restaurant.
