The human gut contains trillions of microorganisms that impact digestion, immune functions, and overall health1. Despite major breakthroughs, we’re only beginning to understand the full extent of the microbiome’s influence on health and disease. Advances in next-generation sequencing and spatial biology have opened new windows into this complex environment, yet many questions remain. This article highlights two recent studies exploring how diet influences microbial...02-24-2025, 06:31 AM
