Tiny fruit, healthier bread, and a daily drink: Study reveals 3 surprising natural remedies to beat constipation
When
bathroom visits slow down, most people reach for fiber supplements or
over-the-counter laxatives. But new evidence suggests the real solution may be
sitting right in the kitchen. A groundbreaking dietary guideline from the
British Dietetic Association reveals that three simple additions to your diet —
kiwi, rye bread and mineral-rich water — can offer powerful relief from chronic
constipation.
The guidelines, published in the Journal of Human Nutrition and Dietetics, are the first to consolidate evidence from 75 randomized controlled trials into clear, practical advice for easing one of the most common digestive complaints worldwide.
Going beyond the fiber myth
Constipation affects more than 10 percent of the global population, with many struggling for years with uncomfortable, stubborn symptoms. For decades, the default advice has been simple: eat more fiber. But the new guidelines challenge that conventional wisdom. Researchers found that while broad fiber intake didn’t have consistent benefits, specific foods did.
“Recommendations for constipation have historically been vague. We now have evidence that certain foods and drinks work better than blanket advice,” said lead author Dr. Eirini Dimidi from King’s College London in the report.
Kiwi: The tiny fruit with big digestive power
Kiwifruit emerged as one of the strongest natural aids for relieving constipation. Rich in both soluble and insoluble fiber, kiwi also contains actinidin, an enzyme known to support digestion. In clinical trials, participants who ate kiwi regularly reported more frequent and easier bowel movements.
Dietitians often recommend eating kiwi with the skin on for maximum fiber, though the texture isn’t for everyone. “It’s an easy, natural way to boost gut health without medications,” said registered dietitian Jessica Cording in an interview referenced in Woman’s Health.
Rye bread: A better bread for your gut
While whole wheat has long been a go-to for boosting fiber intake, rye bread appears to offer even greater benefits for digestion. It contains unique prebiotic fibers that feed healthy gut bacteria and promote softer, more frequent stools.
According to the study, participants who swapped regular bread for rye bread experienced significant improvements in stool consistency and gut comfort. But experts note it may not be suitable for those with gluten sensitivity.
Mineral water: A gentle, hydrating helper
Hydration plays a critical role in keeping digestion on track. But not all water is created equal. The study highlights that mineral-rich water, particularly varieties containing magnesium and sulfates, may offer extra support by drawing water into the intestines and encouraging smoother bowel movements.
“Any water is helpful, but mineral water can provide gentle, natural relief,” noted dietitian Keri Gans in Woman’s Health. This reinforces what many clinicians already advise: fiber alone isn’t enough without adequate fluids.
Practical help for millions
The British Dietetic Association’s guideline represents a shift from one-size-fits-all dietary advice to evidence-backed, specific strategies. Instead of vague instructions to “eat more fiber,” patients can now turn to three accessible, everyday options with proven effects.
The report also stresses that constipation can have many causes, including stress, lack of movement, medications, and other underlying health issues. Dietary tweaks may help many, but persistent symptoms should be evaluated by a healthcare professional.
Chronic constipation can quietly erode quality of life. But a kiwi at breakfast, a slice of rye bread at lunch, and a glass of mineral water throughout the day might just help get things moving again.
