Managing lactose and other food intolerances in Spain

Key rules

• Sin lactosa: Sin lactosa does not mean milk-free, so it is not safe for a milk allergy.
• Milk on labels: Lactose is declared as milk in the ingredients, so look for milk in bold.
• Other intolerances: Fructose, histamine and sorbitol do not have to be declared, so ask staff.
• Cafés: Soy and oat milk are easier to get than lactose-free cow's milk, especially in small towns.

What "sin lactosa" means on a label

Packaged food marked "sin lactosa" is made for people who cannot digest lactose. It is not milk-free. It can still contain milk proteins, so it is not safe if you have a milk allergy.

Lactose is not on the list of 14 allergens that must be highlighted. Milk is on that list, so any milk-derived ingredient, lactose included, is declared as milk. Look for "leche" in bold in the ingredients.

There is no EU-wide legal limit for "sin lactosa". Spanish guidance treats products with this label as having 0.01 g of lactose or less per 100 g (or 100 ml).

Where to buy lactose-free products

Every major supermarket sells leche sin lactosa. You will also find lactose-free yoghurt, cheese and cream. Spanish brands include Pascual, Puleva, Kaiku and Central Lechera Asturiana.

Plant drinks are common too: bebida de soja, de avena and de almendra.

Cafés and bars

Most city cafés offer soy milk and often oat milk, sometimes for a small extra charge. Lactose-free cow's milk is less common in cafés than plant milks. Small-town bars may only have soy, or only regular milk. If you need lactose-free milk every day, ask once and see whether the bar will keep a carton for you.

Fructose, histamine, sorbitol and similar intolerances

Intolerances to fructose, histamine, sorbitol and similar substances are not covered by the mandatory allergen rules. The rules apply only to the 14 listed allergens, such as gluten, milk, eggs, nuts, soy and sulphites.

Restaurants do not have to tell you about other substances, and menus rarely do. Packaged food labels will not flag them either, so read the full ingredients list. You have to ask staff.

How to ask

Menus rarely flag intolerances, so ask the waiter before you order. Keep it short and specific:

• "Soy intolerante a la lactosa. Does this dish have milk, cream or butter?)
• "No puedo tomar fructosa. Does it have fruit, honey or added sugar?)
• "Tengo intolerancia a la histamina. Which dishes have no cured meat, aged cheese or tinned fish?)

Say "intolerancia", not "alergia", unless it is a true allergy. Staff treat the two differently. Ask what is in sauces and fried food, where hidden milk and sugar are common. The questions below cover more common situations.

Frequently asked questions

Does 'sin lactosa' mean the product has no milk?

No, 'sin lactosa' does not mean the product is free of milk proteins. Spanish guidance treats it as lactose at or below 0.01 g per 100 g (or 100 ml). If you have a milk allergy rather than lactose intolerance, look for milk in the ingredients, where it is declared as an allergen.

Will a bar or café have lactose-free milk?

Lactose-free milk is less common in cafés than plant milks. Most city cafés offer soy and often oat milk, sometimes for a small surcharge. Small-town bars may only have soy or regular milk, so ask first or carry a small carton.

Do restaurants have to tell me about fructose or histamine?

No, restaurants do not have to declare fructose, histamine, sorbitol or similar substances. The compulsory rules cover only the 14 listed allergens. Ask the staff directly what is in a dish, and expect menus to say little about these.

Where can I buy lactose-free products in Spain?

You can buy lactose-free milk (leche sin lactosa) in every major supermarket. The same shops stock lactose-free yoghurt, cheese and cream, plus plant drinks such as soja, avena and almendra.
