Scrabbling the Nutraceutical Potential of Berries in Gastrointestinal Disorders: A Review

Researchers are exploiting natural food sources to fight against various diseases. Traditionally, numerous medicinal products have been derived from natural food compounds with therapeutic properties. As a natural food source, berries and their bioactive components have a pivotal role in gastrointestinal (GI) health. Among others, polyphenols are responsible for many of the beneficial properties attributed to berries. Purposely, this review is aimed to summarize the recent literature regarding the impact of berries-derived polyphenols on gut microbiota, gut motility, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), colon cancer, and overall intestinal health. Moreover, efforts have been made to identify the knowledge gaps for future work. Overall, the data suggest that phenolic compounds aid in the improvement of gastric health. Anthocyanins and phenolic acids are successful in reducing metabolic changes and inflammation by inhibiting inflammatory factors. Owing to their fiber content and antioxidant potential, berries are considered a functional remedy to minimize the risks of GI disorders. Additionally, berries support the growth of beneficial bacteria, easing several GI disorders. Yet, the evidence regarding gut motility and IBS is not conclusive. To better understand the mechanisms and their potential in preventing and managing GI problems, further interventions are required.
