Gut health has become one of the biggest topics in wellbeing, and with good reason. Your gut does far more than digest food. It’s home to trillions of bacteria that play a part in how you absorb nutrients, and researchers are still uncovering how these tiny organisms connect with the rest of the body.
The encouraging part is that small, everyday habits can make a real difference to how your digestion feels. This guide covers nine practical ways to look after your gut, along with clear advice on when to speak to your GP.
What Is the Gut Microbiome?
Your gut microbiome is the community of bacteria, fungi and other microbes living mainly in your large intestine. A healthy microbiome tends to be diverse, meaning it contains a wide range of different species.
These microbes help break down fibre your body can’t digest on its own, producing compounds called short chain fatty acids that nourish the cells lining your gut. Diet, sleep, stress, medication and activity levels can all influence which microbes thrive.
Signs Your Gut May Need Some Attention
Everyone has the odd day of bloating or an irregular bowel habit. But if you often notice bloating, wind, constipation, loose stools or discomfort after eating, it may be a sign your digestion needs some support. These symptoms can have many causes, so it’s worth looking at your overall habits as well as speaking to your GP if they persist.
9 Practical Ways to Improve Your Gut Health
1. Eat More Fibre
Fibre is one of the most important nutrients for your gut. It keeps you regular and feeds the beneficial bacteria in your large intestine. The NHS recommends 30g of fibre a day for adults, but most people in the UK eat far less.
Good sources include wholegrain bread and pasta, oats, beans, lentils, fruit, vegetables, nuts and seeds. Increase your intake gradually and drink plenty of water, as adding a lot of fibre at once can cause wind and bloating.
2. Aim for Variety
Different gut bacteria thrive on different foods, so eating a wide range of plants helps support a more diverse microbiome. Research has linked eating around 30 different plant foods a week with greater gut diversity.
That might sound like a lot, but herbs, spices, nuts, seeds, beans, wholegrains, fruit and vegetables all count. Swapping a plain bag of nuts for a mixed one, or adding a tin of mixed beans to a stew, is an easy way to boost your number.
3. Include Fermented Foods
Fermented foods such as live yoghurt, kefir, sauerkraut, kimchi, miso and kombucha naturally contain live bacteria. Adding small amounts to your meals is a simple way to bring more variety into your diet.
Look for products labelled “live” or “unpasteurised”, as heat treatment can kill the bacteria. If you’re new to fermented foods, start with a small portion and build up slowly.
4. Eat Prebiotic Foods
Prebiotics are types of fibre that act as food for the beneficial bacteria already living in your gut. Good sources include garlic, onions, leeks, asparagus, slightly green bananas, oats, apples and chicory root.
Many of these foods are easy to add to everyday cooking, so there’s no need for anything complicated.
5. Cut Back on Ultra Processed Foods
Diets high in ultra processed foods, which tend to be low in fibre and high in sugar, salt and additives, are linked with lower gut diversity. You don’t need to cut them out completely, but building most of your meals around whole foods gives your gut bacteria more of what they need.
6. Stay Hydrated
Water helps fibre do its job, keeping stools soft and easier to pass. The NHS suggests drinking 6 to 8 glasses of fluid a day, and more if you’re active or it’s hot. Water, milk, sugar free drinks, tea and coffee all count.
7. Keep Moving
Regular physical activity can help food move through your digestive system and may support a more varied microbiome. Walking, cycling, swimming and strength training all count, so choose activities you genuinely enjoy and can stick with.
8. Look After Your Sleep and Stress Levels
Your gut and brain are closely connected through what’s often called the gut brain axis. Many people notice their digestion changes when they’re stressed or short on sleep.
Aim for a regular sleep routine, and find ways to unwind that work for you, whether that’s a walk outdoors, breathing exercises, reading or time with friends.
9. Consider a Supplement if Your Diet Falls Short
Food should always come first, but some people choose supplements as part of their routine. Probiotic supplements contain specific strains of live bacteria. Research is ongoing, and results vary depending on the strain and the person, so it’s best to choose products with clearly labelled strains and follow the serving on the label. The NHS page on probiotics gives a balanced overview.
Some people also use digestive enzymes, which contain enzymes that help break down proteins, fats and carbohydrates. You can explore both in our gut health collection and probiotics range, or browse digestive enzyme formulas from Enzymedica.
Gut Health and Nutrient Absorption
A healthy gut helps you absorb the vitamins and minerals you eat. Conditions that affect the gut, such as coeliac disease or Crohn’s disease, can make it harder to absorb nutrients like iron and vitamin B12. Our guide on which vitamin deficiencies can make you feel cold explains how some of these deficiencies can show up.
If your diet is limited, a daily multivitamin from our health and wellbeing collection can help fill nutritional gaps.
What About Antibiotics?
Antibiotics are important medicines, but they can temporarily reduce the number and variety of bacteria in your gut. Always take antibiotics exactly as prescribed. Afterwards, eating plenty of fibre, plant foods and fermented foods can help support your gut as it recovers. If you want to take a probiotic alongside antibiotics, ask your pharmacist about timing first.
When to See Your GP
Lifestyle changes can help with everyday digestive niggles, but some symptoms need medical advice. See your GP if you have:
- A change in your bowel habits lasting three weeks or more
- Blood in your stools or bleeding from your bottom
- Unexplained weight loss
- Ongoing tummy pain, bloating or discomfort
- Difficulty swallowing or persistent heartburn
- Extreme tiredness for no clear reason
Your GP can check for conditions such as irritable bowel syndrome, coeliac disease or food intolerances and help you find the right approach.
Frequently Asked Questions
How long does it take to improve gut health?
Your gut bacteria can start to change within days of changing your diet, but lasting improvements usually come from consistent habits over several weeks and months.
Are probiotics or prebiotics better?
They work differently. Probiotics contain live bacteria, while prebiotics feed the bacteria already in your gut. Getting prebiotics from foods like oats, onions and bananas is a great foundation for most people.
Can stress affect my digestion?
Yes. Stress can affect how quickly food moves through your gut and may make symptoms like bloating or loose stools worse for some people.
Do I need a supplement for good gut health?
Not necessarily. A varied, fibre rich diet, regular activity, good sleep and managing stress are the most important steps. A supplement can be an option if you feel your diet falls short.
Is bloating always a sign of poor gut health?
Not always. Occasional bloating is normal, especially after large meals or high fibre foods. Persistent or painful bloating should be checked by your GP.
Final Thoughts
Looking after your gut doesn’t require a complicated plan. Eating more fibre, enjoying a wide variety of plant foods, including fermented and prebiotic foods, staying active, sleeping well and keeping stress in check all help support your digestion. Supplements can play a supporting role, but they work best alongside healthy everyday habits.
