Discover how fiber can help prevent travel constipation, support digestion, and keep you feeling your best wherever your journey takes you.
Content outline
Whether you’re heading off on vacation, travelling for business, or taking a weekend road trip, there’s one travel issue that many people don’t account for, and that’s changes in their digestion.
Long flights, different foods, disrupted daily routines, dehydration, and travel stress can all impact the normal functioning of your digestive system. For many travellers, this can lead to constipation, bloating, diarrhoea, or even just not feeling themselves. Fortunately, there’s one simple nutrient that can help keep your digestive system moving, support your gut microbiome, and maintain your energy levels: soluble fiber.
By making soluble fiber part of your usual travel routine, you can support regular bowel movements, nourish your gut microbiome, and feel more comfortable throughout your trip.
Why does travel affect your digestion?
Many people notice changes to their digestion within a few days of travelling. Travel constipation is very common, and is most likely in people who have conditions, such as celiac disease, chronic constipation, or irritable bowel syndrome. There are several reasons why it can occur, including dehydration, diet changes, and stress.
Diarrhea is another common complaint, affecting between 40 and 60% of travellers, but this is often caused by Escherichia coli [1]. Traveller's diarrhoea is present in up to 85% of returned travellers. Other common gastrointestinal complaints when travelling include bloating, abdominal pain (83%), and fatigue.
Here are some of the most common causes of traveller’s constipation:
Dehydration
Air travel, high temperatures, and busy schedules can all increase the risk of dehydration. Without enough fluid, stools become harder and more difficult to pass.
Dietary changes
Visiting new places often means sampling the local cuisine, which can lead to richer meals, more processed foods, and fewer fruits, vegetables, and wholegrains. These foods can leave you feeling blocked up and bloated due to their lack of fiber.
Routine changes
Your digestive system craves consistency. Waking up earlier, crossing time zones, skipping breakfast, and spending hours lounging by a pool can all slow bowel movements, leaving you feeling sluggish and bloated.
Stress
No matter your reason for travelling, at some point, it will be stressful. Whether your flight is delayed or you’re stuck in traffic, stress can play havoc with your digestive system.
Sitting for long periods
Whether you’re driving, flying, taking a train, or sitting around the pool, prolonged sitting reduces the amount of exercise you get, which slows the movement of food through your digestive tract and can lead to constipation.
What is fiber?
Fiber is a type of carbohydrate that is found naturally in plant foods that your body cannot fully digest. Instead of being broken down like other carbohydrates by digestive enzymes, fiber passes through your gastrointestinal tract untouched until it reaches your colon, where it can be fermented by gut microbes [2].
There are two main types of fiber. They are:
|
Type |
What it does |
Sources |
|
Soluble fiber |
Absorbs water to form a gel-like substance that softens stools and nourishes beneficial gut bacteria [3] |
Oats, apples, beans, citrus fruits, psyllium |
|
Insoluble fiber |
Adds bulk to stool and helps food move through the digestive tract [4] |
Whole grains, vegetables, nuts, and seeds |
Many fiber-rich foods contain both types, and others, including resistant starch, which all play an important role in digestion. Making sure you get enough fiber both when travelling and as part of your usual daily routine is key to supporting your digestive health.
However, even on a normal day, most people do not reach their daily fiber targets. Check out our Why You Need 36% of Your Daily Fiber: A Deep Dive into Modern Dietary Gaps blog for more information.
How fiber supports healthy travel
Fiber is an essential nutrient while travelling because it can prevent a sluggish digestive system, maintain a healthy and balanced gut microbiome, and keep your energy levels maintained. It can also help to bulk up your stools for easier transit through the colon, prevent traveller’s constipation, and uncomfortable bloating.
1. Keeps you regular
Fiber, whether in natural foods or in supplement form, helps to keep your bowels working and regular. One study found that 66% of people responded to daily fiber supplementation and improved stool consistency [5].
Soluble fiber absorbs water, while insoluble fiber increases stool bulk. Together, they help stools move through the digestive tract more efficiently, reducing the risk of constipation while travelling.
2. Supports your gut microbiome
Fiber doesn’t just benefit your digestive tract; it also feeds the trillions of beneficial bacteria in your gut. Certain fibers act as prebiotics, meaning they provide nourishment for beneficial microbes, which produce special compounds called short-chain fatty acids (SCFAs), which support your gut health and cells that line your colon [6].
When these beneficial microbes are in abundance, your microbiome remains balanced and steady, even when your diet changes during travel. A diverse gut also helps protect you from invading pathogens [7], another key reason for changes in digestion while travelling.
3. Reduces bloating
Bloating is another common travelling complaint. While suddenly increasing fiber intake can temporarily increase gas, consuming adequate fiber consistently, alongside regular hydration, supports bowel regularity and can reduce feelings of discomfort over time.
4. Keeps you feeling fuller
With irregular meal times and frequent snacking, holiday weight gain is common. The average weight gain on holiday is 0.37 kilograms [8]. However, fiber slows digestion, helping you feel satisfied for longer after meals. This may make it easier to avoid constant grazing on less nutritious convenience foods while travelling.
