Non-Invasive Modulation of the Gut Microbiome: Harnessing Natural Products as Non-Invasive Modulators of the Gut Microbiome

The gut microbiome has emerged as a pivotal determinant of human health, shaping metabolic balance, immune responses, and vulnerability to disease. Growing scientific evidence reveals that natural products—ranging from dietary fibers and phytochemicals to bioactive microbial metabolites—offer powerful, non-invasive means to modulate gut microbial communities. Rather than disrupting microbial ecosystems, these compounds act through prebiotic, antimicrobial, and signaling pathways to foster resilience and host–microbe symbiosis.This book explores the molecular and ecological interactions between natural compounds and the gut microbiota, highlighting recent methodological advances and insights from both preclinical and clinical research. With a particular focus on plant-derived polyphenols, fibers, and microbiota-derived metabolites, it examines how natural products can be harnessed as precision tools for microbiome modulation. Addressing both therapeutic potential and translational challenges, this volume provides a forward-looking perspective on sustainable, nature-based strategies to support gut health and prevent disease.
