Introduction: Constipation is a widespread digestive issue characterized by infrequent bowel movements and difficulty in passing stools. While conventional treatments include dietary fiber, laxatives, and lifestyle changes, recent studies have suggested that kiwifruit may offer a natural and effective alternative. This narrative review evaluates the efficacy of kiwifruit in managing and alleviating symptoms of constipation. Aim of the study: The primary aim of this study is to synthesize existing research on the effectiveness of kiwifruit in treating constipation. By examining various clinical trials and observational studies, the review aims to elucidate the therapeutic benefits and mechanisms of action of kiwifruit in improving bowel function. Materials and Methods: A comprehensive literature search was performed using databases such as PubMed, Scopus, and Google Scholar. Data were extracted and analyzed regarding the frequency of bowel movements, stool consistency, and overall gastrointestinal health following kiwifruit consumption. Results: The review identified that regular consumption of kiwifruit significantly enhances bowel function in both constipated and non-constipated individuals. Clinical trials consistently report increased stool frequency, softer stool consistency, and reduced colonic transit time. The beneficial effects are attributed to the high fiber content of kiwifruit and the presence of the enzyme actinidin, which promotes digestion and bowel movements. Kiwifruit was found to be well-tolerated with minimal adverse effects. Conclusion:Kiwifruit appears to be a promising natural remedy for constipation, providing substantial improvements in bowel movement regularity and stool characteristics. Its high fiber content and unique enzymatic properties contribute to its effectiveness. Further research is recommended to explore the long-term benefits and potential applications of different varieties of kiwifruit in diverse patient populations.
