Corn is widely used
Tacos, tortillas, tostadas and many traditional dishes are commonly made with corn.
After nine months in Mexico, I share my personal experience with supermarkets, restaurants, corn tortillas, air travel and everyday life with coeliac disease.
Discover my experienceMexico can be a surprisingly comfortable destination for people with coeliac disease. Many traditional dishes are based on corn, rice, meat, fish, vegetables and fresh ingredients. However, caution is still important because wheat, shared cooking surfaces, fryers and certain sauces may cause accidental gluten contamination.
Tacos, tortillas, tostadas and many traditional dishes are commonly made with corn.
Ask about shared fryers, grills, sauces, marinades and how the tortillas are prepared.
Even corn-based products may contain traces of wheat or be produced in shared facilities.
Snacks, an explanation card and a list of suitable foods can make the trip much more relaxed.
After nine months in Mexico, I can say that travelling with coeliac disease is possible and can be much easier than it initially appears. Good preparation, clear questions and careful food choices make the biggest difference.
One major advantage is that corn plays a central role in Mexican cuisine. Many traditional dishes are prepared with corn tortillas, rice, beans, meat, fish, vegetables, avocado and fresh salsa. This means there are many meals that can naturally be made without gluten-containing ingredients.
However, a corn-based dish is not automatically safe for someone with coeliac disease. In my daily experience, shared grills, fryers, sauces, spice mixes and tortilla preparation were the main areas where I needed to ask additional questions.
I found it especially helpful not to ask only whether something was “gluten-free”, but to explain that even a small amount of flour or cross-contamination could be a problem. Not everyone is familiar with coeliac disease, but specific questions about food preparation are usually understood.
My main lesson: Mexico offers many suitable foods, but safety does not depend only on the ingredients. How and where the food is prepared matters just as much.
Personal experience after nine months in Mexico
Corn, rice, beans, meat, fish, fruit and vegetables form the basis of many Mexican dishes.
Always ask about flour, sauces, breading, shared cooking surfaces and fryers.
Carrying snacks, a Spanish explanation and a few researched restaurants makes travelling much easier.
In the larger supermarkets of the Riviera Maya, I found many simple foods that made it easy to prepare gluten-free breakfasts, snacks and light meals.
I tried to visit a larger supermarket shortly after arriving. This gave me safe food in my accommodation for the first few days and meant I was not completely dependent on restaurants for every meal.
Natural or minimally processed foods were particularly useful, including fruit, vegetables, eggs, plain yoghurt, cheese, rice, beans, tuna and simple corn products. I still checked the current ingredient list and allergen warnings on all packaged foods.
The selection varied between branches. In tourist destinations such as Tulum, Playa del Carmen and Cancún, larger supermarkets usually carried more international, organic or specially labelled products.
Product ranges and labels can change. However, these chains were useful starting points for my first grocery shop.
A wide selection of staple foods, fresh produce, snacks, drinks and some imported products.
Useful for fruit, vegetables, dairy products, eggs, rice, beans, tinned foods and Mexican brands.
Depending on the branch, it offers a good selection of staple foods, fresh products and packaged snacks.
Often useful for imported, organic or specially labelled products when a branch is available nearby.
Bananas, avocados, mangoes, tomatoes and limes are useful for breakfasts and snacks.
Eggs, plain yoghurt and cheese were useful for simple breakfasts and light meals.
Simple staple foods that are easy to combine. I checked seasonings and additives in prepared versions.
Useful in accommodation with a small kitchen and as an addition to rice, salads or corn crackers.
For excursions, I chose sealed products with an ingredient list I could clearly check.
Tortillas, tostadas, corn flour and crackers can be useful, but each product must still be checked individually.

Small shops and convenience stores were useful for water, drinks, fruit or individual packaged snacks. However, I would not rely on them alone for a complete gluten-free grocery shop.
Water and bottled drinks
Fruit or plain yoghurt, when available
Sealed snacks with a clear ingredient list
Buy a few reliable staple foods and snacks on your first day. This gives you an alternative when a restaurant cannot offer a safe option or an excursion lasts longer than expected.
Corn tortillas are part of everyday life in Mexico and can be a very practical alternative to bread and wheat tortillas for people with coeliac disease.
Many traditional tortillas are made only with nixtamalised corn, water and sometimes a little salt. They therefore contain no gluten ingredients naturally. However, this does not automatically mean that every corn tortilla is safe.
Maseca is widely used in Mexico. It is an industrially produced corn flour used to prepare tortillas, tamales and other traditional dishes. During my stay, I found it especially practical because it is easy to find in many supermarkets and can be used to make simple corn tortillas at home.
With packaged products, I still check the current ingredient list and any warnings about possible traces. Recipes, production facilities and labels can change. For coeliac disease, it is therefore important to consider not only the corn itself, but also how the product is manufactured.
At a tortillería, I always ask whether they work exclusively with corn. When wheat tortillas are also made, I ask whether separate machines and work surfaces are used. When the answer is unclear, I prefer not to eat the product.
One of the most important lessons from my time in Mexico was that ingredients and preparation must be considered separately. A tortilla may be made only from corn and still become contaminated through flour, machinery or shared work surfaces.
Do not ask only about the ingredients. Also check whether wheat flour is handled in the same area and whether presses, containers, grills or other equipment are shared.
Some tortillas contain wheat flour in addition to corn. This can be especially common in industrially produced or very flexible tortillas.
Corn and wheat tortillas may be produced using the same mixers, presses, conveyor belts or packaging equipment.
In restaurants, corn tortillas are often heated on the same surface as wheat tortillas, bread or breaded foods.
Unpackaged products may be stored near flour, bread or other gluten-containing foods and become contaminated.
Terms such as “100% corn”, “traditional” or “natural” do not by themselves indicate whether cross-contamination is possible.
With packaged tortillas, I therefore always read the full ingredient list. I also look for warnings such as “contains wheat”, “may contain wheat” or references to shared production facilities.
Labelling may vary according to the brand, product version and production date. For that reason, I do not rely only on online recommendations or on packaging I have purchased in the past.

I have coeliac disease. I cannot eat wheat or food contaminated with flour.When the ingredients or preparation cannot be explained clearly, I prefer not to eat the product. A simple meal with rice, vegetables, meat or a packaged product with a label I can verify feels more comfortable than taking an unnecessary risk.
For excursions, long journeys or days when I did not know exactly where I could eat safely, packaged snacks were especially useful. One of the products I often bought during my stay was Salmas.
Salmas are crunchy corn crackers available in many supermarkets, small shops and sometimes petrol stations throughout Mexico.
I found them especially practical because the individual portions fit easily into a bag or backpack. This meant I always had something available on longer excursions when a restaurant could not provide a suitable option or when I was unsure about the preparation.
I often ate Salmas with avocado, cheese, tuna or other simple ingredients. They worked both as a quick snack and as part of a light meal.
Even with a product I have purchased several times before, I check the packaging again. Ingredient lists, allergen warnings and production conditions can change.
Avocado, a little salt and lime juice make a quick and filling snack.
Cheese and fresh vegetables turn them into a simple light meal.
Tinned tuna is practical in accommodation with a small kitchen or during long journeys.
A small pack in your backpack helps when no reliable meal is available.

Salmas were practical in my personal experience. However, this does not mean that every product version or future package will automatically be suitable for everyone with coeliac disease. Always check the current label and decide according to your individual requirements.
Mexican cuisine offers many dishes based on corn, rice, beans, vegetables, meat and fish. However, the dish itself is not the only consideration: preparation in the kitchen is equally important.
During my stay, I explained as clearly as possible that I have coeliac disease and cannot eat wheat or food that has come into contact with flour or shared equipment.
It worked best to speak directly with someone who knew how the dish was prepared. A general answer such as “it does not contain flour” was not enough if the same fryer, grill or work surface was used.
Chips or nachos may be fried in the same oil as breaded food.
Bread and wheat tortillas are often heated on the same surface.
Prepared sauces, soy sauce and seasoning mixes may contain gluten.
Knives, tongs, chopping boards and containers can transfer flour residue.
I have coeliac disease and cannot eat gluten.
Does this dish contain wheat, flour or soy sauce?
Do you use the same fryer or grill?
Can you prepare it separately with clean utensils?
The simpler the dish and the clearer the communication, the more comfortable I felt. When staff seemed unsure or could not answer my questions, I preferred to choose another option.
On a long flight, I do not rely exclusively on the onboard meal. Even when I have ordered a gluten-free meal, I always carry my own food and several snacks.
With many airlines, gluten-free special meals must be requested in advance. I check the booking a few days before departure and ask again at check-in whether the meal is recorded.
The meal may still be missing, incorrectly labelled or include items that cannot be verified clearly. I therefore always carry a complete alternative in my hand luggage.
When bringing my own food, I check the security and import rules of the departure, transit and destination countries. Liquids, fresh food and meat or dairy products may be subject to special restrictions.
Request the gluten-free meal as early as possible through the airline or booking.
Check a few days before travelling that the special meal code is still shown in the booking.
Pack enough sealed snacks and a simple meal for the flight, connections and possible delays.
Before boarding, confirm again that the special meal has been loaded onto the aircraft.

Mexico can be a wonderful destination even with coeliac disease. For me, good preparation, clear questions and always carrying a safe alternative were the most important factors.
Even with familiar products, I check the ingredients, allergen warnings and possible traces every time.
I keep a short Spanish explanation on my phone describing which foods and contamination risks I must avoid.
For excursions and long journeys, I always carry several packaged snacks and enough water.
A small kitchen or at least a refrigerator makes it easier to prepare simple meals yourself.
I look for restaurants, supermarkets and safe alternatives before the excursion rather than once I am already hungry.
I ask about the fryer, grill, utensils, sauces, marinades and shared work surfaces.
The fewer processed ingredients, sauces and preparation steps a dish has, the easier it is to assess.
When the ingredients or preparation cannot be explained clearly, I choose another meal.
Tengo celiaquía. No puedo comer trigo, cebada, centeno ni alimentos contaminados con harina. Necesito que mi comida se prepare por separado, con utensilios limpios y sin utilizar la misma freidora o plancha que los alimentos con gluten.

During my nine months in Mexico, I found many practical options. However, you should never assume that a food is safe based only on its name or brand. Clear communication, repeated checking and a safe alternative helped me enjoy the journey with greater peace of mind.
This article describes personal experience and does not replace medical advice. Labels, recipes and production conditions may change.
Here I answer some of the most common questions about travelling to Mexico with coeliac disease.
In larger cities and tourist areas, gluten-free products and restaurant options are becoming easier to find. Outside these areas, the choice may be more limited, so planning ahead is useful.
Not necessarily. They may contain wheat flour or be prepared on shared surfaces. Always ask about the ingredients and preparation method.
Depending on the region, gluten-free products may be available at Walmart, Chedraui, Soriana, La Comer, City Market and specialist stores. Availability varies by branch.
I explain clearly that I cannot eat wheat, barley or rye and that I must also avoid contamination from fryers, utensils, grills and shared surfaces.
I carry packaged and clearly labelled foods such as nuts, gluten-free bars, crackers, rice cakes or other products I already know and tolerate.
When the ingredients or preparation cannot be explained clearly, I avoid the dish and choose a safer alternative.
