Microbiome and healthy aging: biomarkers, mechanisms, and prevention strategies

The human gut microbiota is crucial in regulating aging and health span. The aging process is linked to substantial alterations in microbiome composition and diversity, often characterized by a decline in beneficial microorganisms and a rise in pro-inflammatory species, which contribute to chronic inflammation and age-related illnesses. Interventions aimed targeting the microbiome, including dietary changes, probiotics, fecal transplants, and lifestyle adjustments, demonstrate potential for enhancing health outcomes in the elderly individuals. Considering hurdles such as population diversity, translational discrepancies from animal models, and ethical dilemmas, progress in tailored microbiome-based therapeutics provides optimism for prolonging healthy longevity. The integration of microbiome research with multi-omics and AI-driven precision medicine is poised to revolutionize preventive and therapeutic approaches for aging populations. Ongoing interdisciplinary research is essential to fully exploit the microbiome's potential in fostering healthy aging and alleviating the impact of age-related illnesses.
