Polyphenols are a diverse group of naturally occurring compounds found abundantly in plant-based foods such as fruits, vegetables, tea, coffee, and cocoa. While polyphenols are most widely recognized for their antioxidant and anti-inflammatory properties, emerging evidence suggests they may play a role in supporting digestive health, including the management of constipation in adults. Some scientific studies have explored the effects of polyphenol-rich foods (such as prunes, kiwifruit, and certain teas) on bowel function. For instance, prunes are high in both fiber and polyphenols, and clinical trials have shown that regular consumption can significantly improve stool frequency and consistency in people with constipation. The mechanism is believed to involve both increased water content in the stool and modulation of the gut microbiota, as polyphenols can act as prebiotics, stimulating the growth of beneficial bacteria that produce short-chain fatty acids, which in turn enhance gut motility. However, while these results are promising, the evidence is not robust across all polyphenols or all polyphenol-rich foods, and most studies do not isolate the effect of polyphenols from other components like fiber. Therefore, the overall quality of evidence specifically linking polyphenols (as a class) to relief of constipation is modest (rated 2/5). More targeted research is needed to determine which polyphenols, at what doses, are effective for constipation in adults.
