The first time you explain a severe nut allergy in another language, you realise very quickly how much you normally rely on tone and body language as well as words. At home you can tell whether someone understands you properly very quickly. Abroad you’re often guessing. Most allergy travel advice begins with the same suggestion to solve this: bring a translation card. It’s sensible guidance that helps remove a lot of anxiety. Allergy translation cards confront one of the hardest parts of travelling with nut allergies by giving you the right words immediately, without relying on gestures, guesswork, or confidence in a language you may not speak. But this advice on its own is in danger of creating a false sense of security when it comes to allergy travel safety.
Why allergy cards don’t solve everything
What allergy cards often don’t do is confirm how ingredients are stored, how carefully staff interpret what you’ve said, or how seriously kitchens treat cross-contamination risks. A sentence can be translated perfectly and still be misunderstood in practice. Translating an allergy goes behind the language itself. It depends heavily on whether the person hearing you has the training, confidence, and permission to act on what you’ve told them. There are always levels of subjectivity and trust involved, and making the right judgement on if a meal is safe or not only comes with experience.
Translation cards work best when they’re part of a wider approach. Choosing where you eat carefully, recognising uncertainty early, and accepting when to walk away often matter more. They are one tool in a wider arsenal, and should be paired with the confidence to not feel like an inconvenience when explaining your allergy. They make travelling with a nut allergy easier, but they were never meant to do the whole job on their own. What they really do is remove one of the biggest barriers at the start of a conversation. The rest still depends on judgement, preparation, and recognising when something doesn’t feel certain enough.
Culture and destination-specific awareness
Allergy awareness is very different across countries, and is a huge factor in how effective allergy cards are. For example, France and Italy have well established food cultures with increasingly sophisticated awareness of allergen requirements - a card there is likely to be understood in the spirit that it's intended, with menus that often list the 14 major allergens as per EU law. Europe as a whole has a relatively high prevalence of anaphylactic allergies, and sees a lot of tourism where restaurants are more likely to be used to catering to many different needs.
Southeast Asia, parts of India, or regions where nut-based cooking is so embedded it's almost invisible in ingredient lists, present a different challenge entirely. The card might be read carefully and genuinely misunderstood, not through carelessness but because the concept of a life-threatening reaction to something used daily in every kitchen simply hasn't been encountered before. Before you travel, it's worth researching not just the language but the food culture - how central nuts are to the local cuisine, how ingredient transparency tends to work in local restaurants, and whether allergy awareness has begun to reach that particular region. Learning about different food cultures can change how you use your card, and how much you rely on it.
I've eaten my way across India eight times, including at my own wedding, and managed that with careful preparation, an incredibly supportive family network, and a constant low-level vigilance that never fully switched off. And still, one evening near Delhi, a single mouthful of curry was enough to start an anaphylactic reaction. This wasn’t a reason to stop travelling with a nut allergy. It's a reason to understand that preparation reduces risk without eliminating it, and that knowing what to do in the moment matters as much as everything you do beforehand.
Selecting restaurants when travelling
The instinct when travelling with a nut allergy is often to gravitate towards places that look familiar. International chains, tourist menus in English, restaurants with 'allergy friendly' listed somewhere near the entrance. Sometimes this can be counter-intuitive. A restaurant catering primarily to tourists has often learned a handful of allergy phrases without the kitchen behind them understanding the complexities. McDonalds is an interesting example; UK menus are easily navigable for allergy sufferers, but in the US nut traces and oils are often found across different franchises. A busy local restaurant with a handwritten menu in a different language, and a chef who has cooked the same five dishes for twenty years, may actually offer more certainty even if the conversation is harder to start. What you're really looking for is a kitchen that has genuine control over what goes into food, and staff with the confidence to say no or check rather than reassure for the sake of securing your business. Hesitation from a waiter who goes to check with the chef can often be a better sign than immediate confidence that everything is fine.
The conversation beyond the card
Showing staff an allergy card is the beginning of a conversation and not the end of one. What happens next tells you most of what you need to know. A good response involves someone reading it carefully, asking a clarifying question, or going to check with the kitchen. A concerning response could be immediate reassurance and dismissal, "yes, no problem", without the card being fully read, or without any visible consideration of what you've actually asked. It's worth having one or two follow-up questions ready regardless of language barriers. Reconfirming for specific dishes, and especially when ordering desserts. Asking whether the sauce or the dressing is made fresh or comes pre-prepared. Asking specifically about traces and not just the allergen itself. The specific question matters less than the response it generates which should be a genuine attempt to understand and accommodate. This is not to say that an immediate response means it’s always an unsafe environment, it might be that the restaurant encounters many people with allergies. In those cases, it’s worth asking exactly that as a follow up, or if they’re able to prepare your food in a separate kitchen space.
When to walk away
One of the biggest barriers in safe allergy travel isn't just explaining the risks to staff clearly; it's deciding when a situation isn't safe enough and leaving without apology. There's a particular social discomfort in being the person who causes a fuss, especially in someone else's country, especially when staff are trying to be helpful. That discomfort may well be the thing that is most likely to override your judgement when it matters most. The practical test is this: if you cannot get a clear, confident answer about what is in the food you're about to eat, that is enough. It doesn't require rudeness or drama. It requires the same reaction you'd apply to any other risk - if the information isn't there, the risk isn't manageable. Choosing to leave is a skill that gets easier with practice, and it's the one that has the most direct impact on safety.
Allergy cards should be easily accessible
Travelling with a nut allergy has always required more preparation and confidence than most people realise. What's changed is the tools, research, and communities of people who've navigated the same routes, which make that preparation more accessible than it used to be.
Despite this, translations that keep people safe are usually not easily accessible. Allergy sufferers then turn to last-minute online translations and AI tools that do not translate critical information accurately, and put themselves at risk without knowing. What makes sense as a 1:1 translation may not come across well to a native speaker of that language. Translations usually need careful professional input to make sense.
We believe access to professional allergy translation cards should not be a barrier to travel, which is why we offer one for free for all new nutfreed UK members. None of them will remove personal judgement calls, or make every meal certain. But they should give you enough confidence to explore the world as you want to.
