Gut Microbiome, Nutrition, and Metabolic Health

Gut Microbiome, Nutrition, and Metabolic Health explores the vital role of intestinal microorganisms in regulating digestion, immunity, and overall metabolic function. The composition and diversity of the gut microbiome are strongly influenced by dietary patterns, lifestyle, medications, and environmental factors. A balanced gut microbiota supports nutrient metabolism, maintains intestinal barrier integrity, and contributes to immune homeostasis. Disruptions in the gut microbiome have been associated with obesity, type 2 diabetes, inflammatory bowel disease, cardiovascular disease, and other metabolic disorders. Nutrition-based interventions, including dietary fiber, probiotics, prebiotics, and fermented foods, can help promote a healthy microbial ecosystem. Advances in microbiome research, multi-omics technologies, and precision nutrition are improving the understanding of host–microbe interactions and personalized dietary strategies.
