A bowel habit that has become slow, hard work or uncomfortable can affect far more than the bathroom. It may leave you bloated, distracted at your desk, reluctant to eat normally and generally out of sorts. The best foods for constipation are not usually an extreme cleanse or a single ‘miracle’ ingredient. They are everyday foods that increase fibre, support the gut microbiome and help stools hold enough water to pass more comfortably.

Constipation has several possible causes, including a change in routine, low fluid intake, stress, reduced movement, some medicines and conditions such as irritable bowel syndrome (IBS). Food can make a meaningful difference, but it works best as part of a wider, steady routine rather than a rushed fix.

Why food can help constipation

Fibre is the carbohydrate in plant foods that is not fully digested in the small bowel. Some types add bulk to stool, while others form a gel that helps stool stay softer. Fibre also provides fuel for beneficial gut bacteria. As those bacteria ferment certain fibres, they produce compounds that support the health and movement of the bowel.

The key is to increase fibre gradually. Going from very little fibre to a large bowl of bran overnight can worsen wind, cramps and bloating, particularly for people with a sensitive gut. Pair higher-fibre foods with regular drinks through the day. Fibre needs fluid to do its job well.

The best foods for constipation

1. Prunes and dried plums

Prunes are one of the better-studied food options for constipation. They provide fibre as well as sorbitol, a naturally occurring sugar alcohol that draws water into the bowel. This combination can help soften stool and encourage a more regular pattern.

A small serving is often enough to start with, such as two to three prunes daily, increasing only if comfortable. Prune juice may help some people, although whole prunes provide more fibre. If you have IBS or notice sorbitol triggers pain or loose stools, prunes may not be your best first choice.

2. Kiwifruit

Kiwifruit is a practical option for people who find dried fruit too intense. Research suggests that green kiwifruit may support bowel frequency and comfort, partly because of its fibre, water content and natural enzyme activity. Many people tolerate one or two kiwis daily well.

Eat the flesh and, if you enjoy it, the skin after washing it thoroughly for extra fibre. Kiwis also make an easy breakfast addition alongside porridge or yoghurt.

3. Oats and oat bran

Porridge is more than a reliable cold-weather breakfast. Oats contain beta-glucan, a soluble fibre that absorbs water and forms a soft gel in the gut. This can support stool consistency without the rougher texture that some people experience with wheat bran.

Choose porridge oats, overnight oats or oat bran, and build up the portion gradually. Add fruit such as berries, kiwi or a pear, then include milk or a fortified alternative to make it a more satisfying meal rather than a token fibre boost.

4. Linseeds and chia seeds

Ground linseeds, also called flaxseeds, can be a useful addition for constipation because they contain fibre and absorb fluid. Start with one teaspoon stirred into porridge, yoghurt or a stew, and work towards one tablespoon if it suits you. Whole linseeds may pass through undigested, so ground seeds are generally more useful.

Chia seeds similarly form a gel when soaked. They can work well in overnight oats or yoghurt, but do not eat large amounts dry. Whichever seed you choose, drink enough alongside it. Adding seeds without increasing fluids can leave you feeling more bloated or uncomfortable.

5. Beans, lentils and chickpeas

Pulses are rich in both soluble and insoluble fibre, and they offer protein too. Lentil soup, chickpeas in a salad, butter beans in a casserole or mixed beans added to a chilli can make a genuine contribution to daily fibre intake.

They can also cause wind while your gut adjusts. Start with a modest portion a few times a week, rinse tinned pulses thoroughly and increase slowly. For a busy household, tinned lentils or beans are a convenient option, not a lesser one.

6. Pears, berries and oranges

Fruit helps partly because it brings water and fibre together. Pears are particularly helpful for some people because they contain sorbitol, while berries provide fibre in a relatively small serving. Oranges offer fibre when eaten whole, unlike juice, which contains very little.

Aim to include a couple of portions of fruit across the day rather than relying on one very large serving. A pear with a handful of nuts, berries over porridge or an orange after lunch are simple ways to make this habit realistic.

7. Vegetables, especially leafy greens and root vegetables

Vegetables contribute bulk, fluid and a range of plant compounds that support overall gut health. Broccoli, carrots, peas, spinach, green beans, sweet potato and parsnips are all useful choices. Cooked vegetables can be easier to tolerate than large raw salads when your gut is already bloated.

A practical target is to make vegetables a routine part of lunch and evening meals. Soup, traybakes, curries and pasta sauces are often easier to maintain during a working week than trying to reinvent every meal.

8. Wholegrain bread, brown rice and wholewheat pasta

Swapping some refined grains for wholegrain versions raises fibre intake without requiring a separate ‘constipation diet’. Wholemeal toast at breakfast, a jacket potato at lunch or brown rice with an evening meal can all help over time.

However, wholegrains are not automatically better for every gut. During an IBS flare, some people find certain wheat-based foods aggravate symptoms. A dietitian can help identify the fibre sources that suit your digestion without unnecessarily restricting your diet.

9. Nuts and seeds

Almonds, walnuts, pumpkin seeds and sunflower seeds offer fibre alongside unsaturated fats and minerals. A small handful can add useful variety, whether sprinkled over breakfast or eaten as part of a snack.

Portion size matters, as nuts are energy-dense and can feel heavy if eaten quickly when you are already uncomfortable. They are best viewed as one part of a varied diet, not a treatment in isolation.

10. Live yoghurt or kefir, if tolerated

Some live cultured dairy products may support bowel regularity in certain people, particularly when they are part of a fibre-rich diet. Their effects vary between individuals and products, so this is not a guaranteed answer to constipation.

Choose an unsweetened live yoghurt or kefir if you enjoy it and tolerate dairy. Pairing it with oats, berries and ground linseeds can create a breakfast that supports several aspects of gut health at once.

Make the change gradually and consistently

For most adults, the goal is to build towards around 30g of fibre a day, but the pace matters more than reaching a number immediately. Add one change for several days, assess your comfort, then build from there. This is often more effective than a sudden high-fibre overhaul that you cannot sustain.

Fluids, movement and routine matter too. Regular meals can stimulate the bowel’s natural reflexes, while a short walk after lunch or dinner can support gut motility and ease the stiffness that comes with a desk-bound day. When you feel the urge to open your bowels, try not to postpone it. Giving yourself unhurried time, particularly after breakfast, can be surprisingly helpful.

A footstool under your feet on the toilet may also make passing stool easier by bringing your knees slightly above hip level. It is a small biomechanical adjustment, but for some people it reduces straining.

When constipation needs clinical advice

Please seek medical advice promptly if constipation is new and persistent, or comes with unexplained weight loss, blood in your stool, severe abdominal pain, vomiting, fever, anaemia or a major change in bowel habit. You should also speak with a clinician if you are regularly relying on laxatives, or if constipation has not improved after a few weeks of sensible dietary and lifestyle changes.

For children, constipation deserves individual assessment rather than simply adding more fibre. Their age, growth, fluid intake, toilet habits, medication and any tummy pain all matter. A paediatric dietitian can provide appropriate guidance alongside the child’s wider healthcare team.

At Hartwood Health, our dietitians take a joined-up view of gut symptoms. We look at your food pattern, medication, stress, sleep, movement and any overlapping concerns such as IBS or menopause, then help you create a plan that fits ordinary life. The most helpful next step is often not eating perfectly, but choosing one gentle, repeatable change your gut can settle into.
