There’s nothing quite as disruptive as feeling like your body has forgotten a basic function.
Anyone who has spent days waiting for things to “move along” knows how quickly discomfort can take over meals, mood, and even sleep.
And while we’re often told to simply “eat more fibre,” new evidence suggests the solution might be hiding in far more familiar places.
A fresh look at constipation beyond old advice
A major international team of nutrition researchers has reviewed over 75 clinical studies to create the first evidence-based dietary guidelines specifically for adults with chronic constipation.

Their work challenges the long-standing idea that more fibre is always the answer. Instead, they point toward a set of foods with stronger scientific backing—and many are surprisingly accessible.
The researchers highlight that chronic constipation is complex, and no single rule fits everyone. But certain foods seem to offer consistent support for the digestive system.
Here’s where the strongest evidence points:
Kiwi, whole-grain rye bread and mineral water appear to help relieve constipation more effectively than general fibre advice

Why these foods stand out
Kiwi contains natural enzymes and a type of fibre that supports bowel movement without causing heavy bloating.
Whole-grain rye bread offers a unique structure of fibres shown to speed up transit time, especially compared with wheat-based products.
And mineral water rich in magnesium can gently stimulate the intestines while maintaining hydration—two things that matter more than most people realise.
Supplements with real scientific backing
Beyond ordinary foods, the review also found solid evidence for psyllium husk, specific probiotic strains and magnesium oxide—common tools in constipation treatment.

Meanwhile, some widely used remedies, including senna and generic fibre recommendations, did not show strong enough results in controlled studies.
