The Therapeutic Potential of Berry-Derived and Berry-Based Interventions in Inflammatory Bowel Disease: A Comprehensive Systematic Review of Preclinical and Clinical Evidence

Introduction

Berry-derived and berry-based interventions have gained increasing attention for their potential health benefits. Berries are rich in diverse bioactive compounds, including polyphenols and anthocyanins, which are associated with a broad range of biological activities, particularly antioxidant and anti-inflammatory effects. Over the last decade, numerous studies have focused on berries, particularly those from the Ericaceae family (blueberry, cranberry and bilberry), the Solanaceae family (goji berry, Solanum nigrum berries) and the Elaeocarpaceae family (maqui berry). Berries are considered among the best dietary sources of bioactive compounds (BACs). Among chronic gastrointestinal disorders, inflammatory bowel disease (IBD) mainly includes Crohn's disease (CD) and ulcerative colitis (UC), both chronic inflammatory conditions of the gastrointestinal tract. The multifactorial nature of IBD significantly impairs quality of life and makes disease management particularly challenging, increasing interest in complementary approaches, in addition to pharmacological treatments, such as phytotherapeutic strategies based on plant-derived bioactive compounds and, in particular, berry-derived and berry-based interventions.
