Child with Food Allergies in Spain: Gluten, Lactose, and Nuts — A Practical Guide

Travelling to Spain with a child who has a food allergy is very manageable — EU law gives you stronger labelling protections than you may have expected, and Spanish restaurant culture is generally accommodating once staff understand the seriousness of a medical allergy. This guide pulls together the practical information UK and Irish families need: how allergens are labelled, what to say in Spanish, and where the hidden risks really lie.

How Spain Labels Allergens on Food

Spain, as an EU member state, follows the EU Food Information for Consumers (FIC) Regulation (EU No ¹¹⁶⁹⁄₂₀₁₁). Under EU allergen labelling rules, 14 major allergens must be clearly declared on all pre-packaged food and — critically — on food sold loose or in catering settings since 2014. Those 14 allergens are:

• Cereals containing gluten (wheat, rye, barley, oats, spelt, kamut)
• Crustaceans
• Eggs
• Fish
• Peanuts
• Soybeans
• Milk (including lactose)
• Tree nuts (almonds, hazelnuts, walnuts, cashews, pecans, pistachios, macadamia)
• Celery
• Mustard
• Sesame seeds
• Sulphur dioxide and sulphites
• Lupin
• Molluscs

On packaged foods, allergens must be visually highlighted — typically in bold, italics, or underlined — within the ingredients list. The Spanish word for “contains” is contiene, so you will often see declarations written as “Contiene: gluten, leche” (Contains: gluten, milk). This makes label scanning much faster once you know what to look for.

One allergen that catches families off guard is lupin (lupino in Spanish). According to Prepared Travel’s Spain allergen guide, lupin flour (harina de lupino) carries a high hidden-risk score because it is largely unknown to travellers from outside the EU — yet it has clinically significant cross-reactivity with peanuts. If your child has a peanut allergy, add lupin to your watchlist.

For loose foods at bakeries, market stalls (mercados), and deli counters, vendors are legally required to provide allergen information on request. In practice, compliance is variable, particularly at smaller independent stalls. Ask directly and look for a written allergen menu (carta de alérgenos), which well-run establishments display near the counter.

Communicating Your Child’s Allergy in Spanish

Clear communication is your most reliable safety tool. Spanish restaurant staff are generally willing to help, but language barriers can introduce genuine risk — particularly when you need to ask about cross-contamination, which requires more nuance than a simple “I don’t eat X.”

Key phrases to carry on a printed card:

• Mi hijo/hija tiene alergia a… — My son/daughter is allergic to…
• Es alérgico/a al gluten — He/she is allergic to gluten
• Tiene celiaquía — He/she has coeliac disease
• Es intolerante a la lactosa — He/she is lactose intolerant
• Es alérgico/a a los frutos secos — He/she is allergic to nuts
• ¿Contiene…? — Does it contain…?
• ¿Se cocina en el mismo aceite que otros platos? — Is it cooked in the same oil as other dishes?
• Reacción alérgica grave — Severe allergic reaction

For coeliac disease, the distinction between preference and medical necessity matters. Say “Mi hijo tiene celiaquía — no puede comer nada con gluten, ni siquiera trazas” (My child has coeliac disease — he cannot eat anything with gluten, not even traces). Simply requesting “sin gluten” (without gluten) can be interpreted as a lifestyle preference rather than a clinical requirement.

Anaphylaxis UK recommends carrying a printed allergy card in Spanish, especially for children with severe or anaphylactic reactions. Print one specific to your child’s allergen profile before you travel. If your child carries an adrenaline auto-injector (AAI), pack it in hand luggage and ensure every accompanying adult knows how to use it.

Hidden Allergens in Popular Spanish Dishes

Several classic Spanish dishes contain allergens that families don’t anticipate. Understanding what’s actually in the food helps you ask more targeted questions.

Gluten

Bread (pan) arrives at the table automatically in most Spanish restaurants and cafés — tell staff immediately if your child cannot eat it. Many tapas (small sharing dishes) are served on toast or with breadcrumbs (pan rallado). Croquetas (croquettes) contain a béchamel base thickened with wheat flour and are coated in breadcrumbs before frying — they are not safe for a child with a gluten allergy or coeliac disease.

Tortilla española (Spanish potato omelette) is naturally gluten-free in its traditional form, but shared fryer risk is significant. Prepared Travel’s allergen analysis identifies the shared fryer (freidora compartida) as the single most consequential cross-contact risk in Spanish eating out. Always ask whether chips (patatas fritas) are fried separately from battered or breaded items.

Lactose and milk

Dairy is embedded deeply in Spanish cooking. Béchamel, cream sauces, and cheese appear in many dishes that don’t obviously signal dairy. Natillas (a soft custard dessert) and flan both contain milk and eggs. At ice cream (helado) parlours — extremely popular with children on the Costa del Sol and Mallorca — cross-contamination between flavours is routine and dedicated dairy-free scoops are rarely standard. Ask before you let your child choose.

Nuts

Almonds (almendras) appear frequently in Andalusian and Catalan cooking: in romesco sauce, almond-thickened stews, and pastries. Turrón (nougat), sold year-round in tourist areas as both a snack and a souvenir, typically contains almonds or hazelnuts. Avoid loose pastries from bakeries without clear allergen labelling.

Eating Out Safely at Spanish Restaurants

The good news for families managing a child’s food allergy in Spain is that EU legislation has pushed allergen awareness meaningfully forward. Many restaurants now display a printed carta de alérgenos listing which of the 14 regulated allergens each dish contains — this is a legal requirement for catering establishments under EU FIC rules. Ask for it as soon as you are seated.

Practical strategies at the table:

1. Arrive outside peak hours — staff have more time to check with the kitchen and take your query seriously.
2. Ask to speak to the chef (¿Puedo hablar con el chef?) for complex or severe allergies; waiters may not have full kitchen knowledge.
3. Choose simpler preparations — grilled fish (pescado a la plancha), plain rice (arroz blanco), and roasted vegetables (verduras asadas) have fewer hidden ingredients than sauced or fried dishes.
4. Request dedicated utensils and prep surfaces for coeliac children — cross-contamination from shared tongs, boards, and spoons is a real risk.
5. Be cautious at buffets — shared serving spoons transfer allergens between dishes continuously, regardless of what the dishes contain.

For families managing coeliac disease specifically, the Spanish Coeliac Federation (FACE — celiacos.org) maintains a searchable database of certified gluten-free restaurants and products. The Espiga Barrada (crossed grain) symbol on packaging and menus indicates certified gluten-free status under the EU threshold of fewer than 20 parts per million — look for it actively.

Larger tourist areas — the Costa del Sol, Mallorca, Tenerife, and Gran Canaria — tend to have better English-language allergy awareness than rural inland Spain, driven by years of international visitor demand.

Finding Allergy-Friendly Products in Spanish Supermarkets

Spanish supermarkets stock a solid and growing range of allergy-friendly products. The main chains you will encounter are Mercadona, Carrefour, Lidl, and El Corte Inglés — all reliable for reading labels using the highlighted allergen system described above.

Gluten-free (sin gluten)

Mercadona has developed one of the most extensive own-brand gluten-free ranges in Spain, covering pasta, bread, biscuits, and breakfast cereals. Products are labelled sin gluten and many carry the Espiga Barrada symbol. Carrefour Bio and El Corte Inglés’s health food sections carry a similarly wide range. In major tourist resorts, dedicated gluten-free bakeries (panaderías sin gluten) have opened in response to demand — local Facebook expat groups are often the best way to find the nearest one quickly.

Dairy-free (sin lactosa / sin leche)

Lactose-free milk (leche sin lactosa) is stocked in every major supermarket, usually alongside regular milk. Plant-based milks — oat (avena), soy (soja), almond (almendra), and rice (arroz) — are widely available in long-life cartons. If your child has a full cow’s milk protein allergy (CMPA) rather than lactose intolerance, check labels carefully: some products labelled sin lactosa still contain milk proteins and are not safe.

Nut-free

This is the hardest category to source reliably via supermarkets. Nuts are common in Spanish confectionery, pastry, and snack foods, so the safest approach is careful label reading and sticking to brands you already know from home. Avoid loose bakery items without visible allergen signage.

Pack a supply of your child’s known-safe snacks from the UK for the first day and for emergencies — Spanish supermarkets are excellent, but arriving at your accommodation with nothing safe to hand is stressful. See our Spain family health and packing guide for a broader medicine and supplies checklist.

Pre-Trip Checklist for Allergy-Aware Families

Managing a child’s food allergy in Spain is entirely achievable with the right preparation. Work through this list before you travel.

Medical - Confirm adrenaline auto-injectors (if prescribed) are in date and packed in hand luggage, not hold baggage - Carry a letter from your GP or paediatric allergist in both English and Spanish - Apply for a UK Global Health Insurance Card (GHIC) — it covers emergency treatment in Spain and is free - Check your travel insurance policy explicitly covers allergic reactions and anaphylaxis treatment

Documentation - Print Spanish-language allergy cards specific to your child’s allergen profile (free templates available through Anaphylaxis UK) - Save photographs of the cards on your phone as a backup - Note the address of the nearest A&E (urgencias) to your accommodation before you need it

Packing - Bring a small supply of safe snacks from home — useful on travel days and for reassurance on arrival - Prepare a simple shopping list in Spanish (sin gluten, sin lactosa, etc.) for the first supermarket visit - Download an offline translation app in case of poor signal

Research - Confirm your accommodation has a fridge, and ideally a kitchen or kitchenette, for safe food preparation - Contact your hotel or villa in advance about catering for allergies at breakfast - Search the FACE gluten-free restaurant database for your destination if coeliac disease is a concern
