Dietary modulation of the gut resistome: ecological and metabolic pathways driving antimicrobial resistance (opens in new tab)

Antimicrobial resistance (AMR) is traditionally viewed as a consequence of antibiotic exposure and genetic adaptation; however, resistance also emerges from the ecological and metabolic context of microbial communities. The human gut microbiome represents a major reservoir of antibiotic resistance genes (ARGs), and diet is increasingly recognised as a dominant regulator of its structure and function. Here, I synthesise current evidence and propose a conceptual framework in which diet shapes r...
