Travel disrupts your routine, and for many people that includes their eating habits. Long-haul flights, unfamiliar time zones, limited food options at airports, and the temptation to eat whatever is convenient rather than whatever is good all add up. But eating well while travelling is more achievable than it’s often made to sound, and keeping fermented foods in the picture makes a real difference to how you feel.
Why Travel Is Hard on Your Gut
Travel disrupts your gut microbiome in several ways. Time zone changes affect circadian rhythms that regulate digestion. Changes in water quality introduce new bacterial strains. A diet that’s suddenly higher in processed foods and lower in fibre reduces the diversity of gut bacteria. Stress – even positive travel excitement – affects gut motility. Most travellers experience some combination of these effects, and the result is often bloating, irregular digestion, or general discomfort.
The good news is that many of the best strategies for managing gut health while travelling are also the most enjoyable. Eating local fermented foods, avoiding airport fast food, drinking water rather than soft drinks, and sleeping reasonably well are all things worth doing anyway, and they happen to be exactly what your gut needs.
Prioritise Fermented Foods Early
If you can, eat something fermented early on in your trip. Local yoghurt, kefir, kimchi, miso soup, or whatever cultured food is available in your destination helps introduce local bacterial strains into your gut and can ease the transition to a new food environment. This is one of the reasons why eating a proper local breakfast early in a trip is useful beyond just the pleasure of trying new food.
Yoghurt is the most universally available fermented food and one of the gentlest introductions to local bacterial cultures. Eating a bowl of local yoghurt for breakfast in the first few days of a trip is both enjoyable and genuinely good for your gut. The bacterial strains in locally produced yoghurt will be different from what you’re used to at home, and that diversity is beneficial.
What to Eat at Airports
Airport food is generally poor and expensive, and it’s worth spending a bit of planning energy on avoiding the worst of it. Most airports now have yoghurt parfaits or plain yoghurt available at café chains; these are a reasonable option when you need something quick. Bringing your own food through security (check what’s allowed on your specific route) is the better approach when you have the option.
A small tub of yoghurt with a handful of nuts and some fruit is a better airport meal than almost anything you can buy airside, and it will keep you feeling better during and after the flight than a burger and chips. The combination of protein, fat, and live cultures in yoghurt is particularly useful on long-haul flights where digestion slows down significantly.
Staying Hydrated and Eating Fibre
Two things that most travellers don’t get enough of are water and dietary fibre. Both are important for gut health, and both are easy to address if you make conscious choices. Drinking water rather than soft drinks or alcohol on flights and in hot destinations is important for gut motility. Eating fruit, vegetables, and whole grains (rather than the refined carbohydrates that tend to dominate tourist food options) keeps the microbiome fed.
In destinations where you can access a local market, buying fresh fruit and yoghurt for breakfast is one of the best eating strategies available to a traveller. It’s cheap, nutritious, involves real local food, and is genuinely good for your gut. It’s also, incidentally, one of the best travel mornings you can have.
