Eating out and hosting with food allergies

These guides cover the three questions that decide whether a meal works: where an allergen hides in a dish, how it reaches food that does not contain it, and what to ask the kitchen — written per allergen, per cuisine, per city, and for hosts planning a meal for a mixed group.

By allergen

The 14 EU-declarable allergens, one guide each.

  • Eating out with a peanut allergy — Eating out with a peanut allergy comes down to three questions: what thickens the sauce, what oil the kitchen fries in, and whether desserts share equipment with nut work — peanut is a legume, not a tree nut, and it shows up far outside the nut aisle.
  • Eating out with a tree nut allergy — With a tree nut allergy the two things that decide a restaurant meal are the pastry section and the sauces — nuts are ground into dressings, pestos, curries and desserts where nothing visible remains, and bakery areas are the hardest place in a kitchen to keep separate.
  • Eating out with a milk allergy — Dairy-free eating out fails most often on the finishing touches: the butter a steak rests in, the milk powder in a bread roll, the cream that gets stirred into a 'tomato' sauce at the end — so ask about fats and finishes, not just the obvious cheese.
  • Eating out with an egg allergy — Egg is easy to see on a breakfast menu and almost invisible everywhere else — in the glaze on pastry, the emulsifier in mayonnaise and dressings, the binder in burgers and meatballs, and the wash on fresh pasta — so the question to ask is what holds the dish together.
  • Eating out with coeliac disease — For coeliac disease the deciding factor in a restaurant is almost never the recipe — it is the shared fryer, the shared pasta water, the shared toaster and the flour in the air, so ask how the dish is cooked rather than only what is in it.
  • Eating out with a soy allergy — Soy allergy is hard to manage in restaurants because soy is a background ingredient rather than a headline one — it is in the frying oil, the bread, the marinade and the vegetarian protein, so ask about the fat and the seasoning as well as the dish.
  • Eating out with a fish allergy — Fish allergy is less about avoiding fish on the menu and more about avoiding fish in the seasoning — anchovy, fish sauce and Worcestershire sauce turn up in dressings, curries and stews that are never described as seafood.
  • Eating out with a crustacean allergy — Crustacean allergy is one of the most common adult-onset food allergies and one of the easiest to trip over in shared kitchens: the shrimp itself is obvious, but shrimp paste in a curry base, shellfish stock in a risotto and a shared fryer are not.
  • Eating out with a mollusc allergy — Molluscs — mussels, clams, oysters, squid, octopus and snails — are a separate EU-declarable allergen from crustaceans, and the ones that catch people out are the invisible ones: oyster sauce in a stir-fry and clam or squid stock in a seafood base.
  • Eating out with a sesame allergy — Sesame is the allergen most often missed in restaurants because it works as a background flavour rather than a visible ingredient — in tahini-based dressings, in the oil used to finish a stir-fry, and in bread, dips and spice blends where nobody thinks to mention it.
  • Eating out with a celery allergy — Celery is declarable in the EU because celeriac and celery seed hide in almost every savoury base — stock, bouillon, spice mixes, mirepoix and curry powders — so a celery allergy is managed by asking about stock and seasoning rather than about visible vegetables.
  • Eating out with a mustard allergy — Mustard allergy is mostly a sauce and seasoning problem: a teaspoon of mustard is the standard emulsifier in vinaigrette and mayonnaise, and mustard seed is in curry powders, pickles, marinades and spice rubs where it is never named on the menu.
  • Eating out with a lupin allergy — Lupin is a legume flour that has quietly spread through gluten-free and high-protein baking, so a lupin allergy is easiest to manage by treating every bread, pastry and pasta as a question — especially the gluten-free ones.
  • Eating out with a sulphite sensitivity — Sulphites are a preservative rather than a food, so avoiding them in a restaurant means asking about wine, dried fruit, pre-cut potatoes, vinegar and processed meat — the places where a kitchen buys the ingredient already treated.

By diet

Common diets that shape what a group can be served.

  • Eating out on a vegan diet — Eating vegan in a restaurant is rarely about the headline dish and usually about four details: the stock, the fat the dish is cooked in, whether the pasta or bread contains egg or milk, and whether the dessert uses gelatine or honey.
  • Eating out on a halal diet — Eating halal outside a certified venue usually turns on three things: whether the meat is zabiha-certified, whether alcohol is used in cooking or in the sauce, and whether pork-derived gelatine or lard appears in desserts and pastry.
  • Eating out on a kosher diet — Keeping kosher in a non-certified restaurant is limited by design: the rules cover permitted species, slaughter, the separation of meat and dairy and the equipment used, so what the kitchen cooks in matters as much as what it cooks.
  • Eating out on a low-FODMAP diet — Low-FODMAP eating out is dominated by onion and garlic, which are in almost every savoury base in professional cooking — so the useful question is not 'is this low-FODMAP' but 'is there onion or garlic in the base, the stock or the seasoning'.
  • Eating out on a keto or low-carbohydrate diet — Eating keto in a restaurant is mostly an ordering skill rather than a menu-reading one: most kitchens will swap a starch for a vegetable, and the carbohydrates that break the day are usually in the sauce, the glaze and the drink rather than on the plate.

By cuisine

How each kitchen tradition interacts with the common allergens.

  • Italian food with allergies — Italian restaurant cooking is built on wheat, hard cheese and egg, so it is demanding for gluten, milk and egg and comparatively easy for soy and sesame. The saving grace is that most sauces are short recipes a chef can describe from memory.
  • Japanese food with allergies — Japanese cooking is light on dairy and nuts and heavy on soy, wheat and fish: soy sauce and dashi are in almost everything, which makes it one of the harder cuisines for soy, gluten and fish and one of the easier ones for milk and tree nuts.
  • Thai food with allergies — Thai cooking leans on peanut, fish sauce and shrimp paste as base seasonings rather than as toppings, which makes it demanding for peanut, fish and crustacean allergies and comparatively straightforward for milk and gluten if the soy sauce question is handled.
  • Indian food with allergies — Indian restaurant cooking is generous with dairy and nuts and light on egg and fish, so it suits gluten-free and vegan diets well while being one of the more demanding cuisines for milk and tree nut allergies.
  • Mexican food with allergies — Mexican cooking is maize-based at its core, which helps gluten-free eating, but restaurant versions lean heavily on cheese and crema, and mole and some sauces carry nuts, seeds and chocolate.
  • Chinese food with allergies — Chinese restaurant cooking depends on soy, oyster and sesame-based seasoning and on a single wok that cooks every order, which makes it demanding for soy, gluten, sesame and shellfish while being one of the easiest cuisines for dairy.
  • Middle Eastern food with allergies — Middle Eastern and Levantine menus are strong for vegan and dairy-free eating and difficult for sesame, since tahini underlies much of the mezze table — nuts and wheat are also common in both savoury and sweet dishes.
  • French food with allergies — Classical French technique is built on butter, cream, egg and stock, which makes it the most demanding common cuisine for milk and egg allergies — but its sauces are precise recipes, so a trained kitchen can usually answer exactly what is in one.

By city

What eating out is actually like, and what the local rules give you.

  • Eating out with allergies in Stockholm — Stockholm has Sweden's widest range of kitchens and the most staff used to allergy questions, so the practical challenge is less whether a venue can accommodate you and more choosing formats — booked table service rather than lunch buffets and counter service — where the kitchen has time to answer properly.
  • Eating out with allergies in Gothenburg — Gothenburg's food identity is west-coast seafood, which makes it one of the easier Swedish cities for a gluten-free or dairy-free diner and one of the harder ones for a fish, crustacean or mollusc allergy — shared fryers, shared grills and shellfish stock are the norm rather than the exception.
  • Eating out with allergies in Malmö — Malmö has the most developed Middle Eastern and falafel scene in Sweden, which makes it excellent for vegan and dairy-free eating and demanding for sesame allergy, since tahini is a base ingredient across much of that food rather than a garnish.
  • Eating out with allergies in Uppsala — Uppsala's eating out is shaped by its student population: a dense café and lunch-deal scene, a lot of buffet and counter service, and high turnover of staff — which means asking the same allergy question twice at the same venue can genuinely produce two different answers.
  • Eating out with allergies in Linköping — Linköping is a mid-sized university and technology city where most eating out happens at lunch, in venues designed for volume — so the single most useful habit is to arrive outside the lunch rush, when a kitchen can actually stop and answer an allergy question.
  • Eating out with allergies in Västerås — Västerås is a compact city where a large share of restaurant meals are weekday lunches and hotel or conference catering — and conference catering is the setting where an allergy stated at booking gets handled well and an allergy stated on the day usually does not.
  • Eating out with allergies in Örebro — Örebro combines a student population with a strong weekday lunch trade, so the allergy experience depends heavily on format — table service and booked meals work well, while counter service and lunch buffets carry the usual shared-utensil problems.
  • Eating out with allergies in Helsingborg — Helsingborg's food scene is Skåne-influenced and seafood-adjacent, with a strong café and bakery culture — so the two things worth planning around are shellfish in the stock at seafood-leaning venues and cross-contact at bakery counters.
  • Eating out with allergies in Norrköping — Norrköping's restaurant scene is concentrated around the old industrial landscape and the city centre, with a mix of independent kitchens and lunch-focused venues — small enough that a phone call before you go is both practical and unusually effective.
  • Eating out with allergies in Jönköping — Jönköping's eating out is dominated by lunch trade, campus catering and conference venues around Vättern, which means the most useful step for an allergy is almost always taken before you arrive — at booking, or with the event organiser.
  • Eating out with allergies in Lund — Lund is a compact university city where much of the eating happens in cafés, student nations and lunch venues within a few streets — an advantage for allergies, because the same small set of places can learn your requirement if you become a regular.
  • Eating out with allergies in Umeå — Umeå is a northern university city with a compact centre and a strong student population, so the practical realities are a smaller venue count, earlier kitchen closing times and a real benefit to booking rather than walking in.
  • Eating out with allergies in Borås — Borås is a mid-sized city with a centre-focused restaurant scene and a strong weekday lunch trade — the allergy strategy that works best here is the one that works in most Swedish cities of this size: book, state the allergen at booking, and avoid the buffet.
  • Eating out with allergies in Sundsvall — Sundsvall is a coastal northern city with a compact stone-town centre, a substantial hotel and conference trade, and a smaller independent scene — so most allergy work happens at the booking stage rather than at the table.
  • Eating out with allergies in Gävle — Gävle is a mid-sized coastal city with a compact centre, a notable baking and confectionery heritage, and a moderate restaurant count — which makes bakery cross-contact and advance booking the two things most worth planning around.

For hosts

Planning and cooking a meal a whole group can eat.

  • Hosting a dinner when guests have different allergies — Cook one meal that everyone can eat rather than a main dish plus separate 'allergy plates' — build the menu from the intersection of what the group can have, keep every risky component on the side, and label everything, because a single shared safe menu removes almost every way the evening can go wrong.
  • How to collect everyone's dietary needs before an event — Ask each guest privately, ask the same three questions every time — what you avoid, what happens if you don't, and what you need me to control — and keep the answers somewhere you can reread the morning of the event rather than in a chat thread you will have to scroll.
  • Cooking safely gluten-free for a guest with coeliac disease — For coeliac disease the recipe is the easy part and the kitchen is the hard part: cook the gluten-free food first in clean pans, keep flour sealed and away from the work surface, use separate toasters, colanders and butter, and serve before any bread reaches the table.
  • Hosting a nut-free party — A genuinely nut-free party is built by keeping nuts out of the house for the event rather than by avoiding them in the recipes — the failure points are almost always bought-in desserts, guest-brought dishes, snack bowls and the chocolate on the side, not what you cooked.
  • Running an allergy-safe kids' birthday party — For a children's party, make the whole food table safe for the most restricted child rather than preparing a separate plate — children swap food, touch everything and cannot be relied on to check, so separation fails and a single safe menu works.
  • Running a potluck when someone has a food allergy — A potluck is the hardest format to make safe because you control neither the ingredients nor the kitchens — so either assign dishes and require ingredient lists, or tell the affected guest honestly that the food cannot be cleared and plan a safe dish they can rely on.
  • Serving a buffet or julbord when guests have allergies — A buffet loses allergen control the moment guests start serving themselves, so the fix is structural: plate the affected guests' portions in the kitchen before the buffet opens, and treat the buffet itself as uncontrolled no matter how well it is labelled.
