Traveling Gluten Free: How to Eat Safely on the Road

Traveling gluten free comes down to three habits: carry food that is safe, read labels for the FDA’s gluten-free claim, and tell every kitchen about the need before ordering. That is also the core advice the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) gives people with celiac disease who eat away from home.

I cook most nights at home, so the road is where a careful diet usually slips. The fix I keep coming back to is boring. Pack the first day’s food, find a grocery store near where you sleep, and ask restaurants how a dish is made, not only what is in it. Shared fryers and toasters are the first things I ask about.

Who needs to eat gluten free while traveling

The FDA estimates that about 3 million people in the United States have celiac disease. For them, the NIDDK’s eating guidance for celiac disease is built around avoiding gluten entirely, so a slip on vacation is more than a bad meal. Others skip gluten by preference, and the same planning helps them too.

According to the NIDDK, gluten occurs naturally in wheat, including durum, emmer, semolina and spelt, as well as in barley, rye and triticale. Barley also hides in malt, malt extract, malt vinegar and brewer’s yeast. Those names are worth memorizing before a trip, because they turn up on menus and labels far from home.

Pack gluten free snacks for the trip

A bag of safe food is the simplest insurance. With snacks on hand, a delayed flight or a long drive does not force a risky choice.

The NIDDK lists many whole foods as naturally gluten free, including meat, fish, fruits, vegetables, rice and potatoes, as long as no additives or certain seasonings are added. Packaged snacks are easier to trust when they carry a gluten-free label. For flights, check the airport security rules on liquids and spreads before packing dips or nut butters.

On longer trips, shipping a box of snacks ahead can save suitcase space. Ask the hotel first whether it will hold packages for a guest before check-in. Then look up grocery stores near the destination, so the first stop after arrival is a place to restock.

Reading gluten-free labels on the road

In the US, a “gluten-free” claim has a legal meaning. Under an FDA rule from August 2, 2013, foods labeled gluten-free must contain less than 20 parts per million of gluten, as the NIDDK explains. The claim is voluntary, so a food without the label is not automatically unsafe. It simply has not made the claim.

A second FDA rule, from August 12, 2020, covers fermented and hydrolyzed foods. That list includes yogurt, sauerkraut, pickles, cheese, green olives and FDA-regulated beers and wines, generally those under 7% alcohol. It also covers hydrolyzed plant proteins used in soups, sauces and seasonings.

There are gaps to know about. The NIDDK notes that the FDA rule does not cover USDA-regulated foods such as meat and poultry, or most alcoholic beverages. The FDA rule also applies to food sold in the United States, so travelers abroad should learn the local labeling terms before they go.

Ordering at restaurants when traveling gluten free

Restaurant meals take the most planning. The NIDDK’s advice is to check online menus or call ahead to confirm a restaurant can serve a gluten-free meal safely. Booking a table is the natural moment to mention it, since the kitchen then has time to plan.

At the table, the NIDDK suggests telling the server about celiac disease directly. Ask about ingredients and how the dish is prepared, and whether a gluten-free menu exists. Asking to speak with the chef is reasonable too. Dishes that look safe can still pick up gluten through flour dusting, thickened sauces or shared cooking surfaces.

That last risk has a name. The NIDDK defines cross-contact as gluten-containing foods or products touching gluten-free foods. It can happen during growing, processing, storage, preparation or serving. A grilled chicken breast cooked on the same surface as breaded cutlets is one example.

Hidden gluten in sauces, soups and drinks

Regional food festivals and new cuisines are part of the fun of travel. They are also where hidden gluten is hardest to spot. The NIDDK warns that many additives, such as colorings, flavorings, starches and thickeners, are made from gluten-containing grains. It names candy, condiments and soups as places gluten often appears.

Drinks need the same attention. According to the NIDDK, beer, lagers, ale, flavored liquors and malt beverages may contain gluten. At a brewery or a cocktail bar, ask what goes into a drink before ordering it.

Are oats safe when traveling gluten free?

Oatmeal looks like an easy breakfast on the road. The NIDDK says research shows most people with celiac disease can eat moderate amounts of oats. However, it also says to eat only oats labeled gluten-free, because cross-contact between oats and gluten grains is common. A bowl of regular oatmeal from a buffet does not meet that bar. How much is right for one person is a question for a doctor or dietitian.

Staying with friends or at food events

Weddings, reunions and stays with family bring their own pressure. The NIDDK’s guidance is to tell the host about the need ahead of time. If gluten-free food cannot be guaranteed, bring some. A covered dish to share takes the burden off the host and guarantees at least one safe plate.

Flours made from potatoes, rice, corn, soy, nuts, cassava and quinoa are safe options, per the NIDDK. That makes baking for a gathering easier than many people expect.

Tips for traveling gluten free

What foods are naturally gluten free?

The NIDDK lists meat, fish, fruits, vegetables, rice and potatoes as naturally gluten free, as long as they have no additives or certain seasonings. Flours made from potatoes, rice, corn, soy, nuts, cassava and quinoa are also safe. These foods make good travel snacks and are easy to find in grocery stores at most destinations.

What does a gluten-free label mean?

In the United States, foods labeled gluten-free must contain less than 20 parts per million of gluten under an FDA rule from 2013. The claim is voluntary. According to the NIDDK, the FDA rule does not cover USDA-regulated foods such as meat and poultry, or most alcoholic beverages, so those need a closer look.

How do you order gluten free at a restaurant?

The NIDDK recommends checking the menu online or calling ahead to confirm the restaurant can serve a safe meal. At the table, tell the server about celiac disease, ask about ingredients and preparation, and ask whether there is a gluten-free menu. Asking to speak with the chef is also reasonable when the dish is unclear.

Can people with celiac disease eat oats?

The NIDDK says research shows most people with celiac disease can safely eat moderate amounts of oats. It advises eating only oats labeled gluten-free, because cross-contact between oats and gluten grains is common. A doctor or dietitian can advise on how much is right for one person.
