The human gut microbiome composition changes throughout life, influenced by various factors. A diverse gut microbiome, rich in anti-inflammatory compounds, is linked to healthy aging and longevity across diverse populations.
Area of Science:
- Microbiology
- Gerontology
- Immunology
Background:
- The human gut microbiome composition is dynamic and influenced by factors like diet, environment, and aging.
- Alterations in the gut microbiome are associated with various diseases and can impact healthy aging.
- A diverse microbiome producing anti-inflammatory metabolites like short-chain fatty acids is linked to positive aging outcomes.
Purpose of the Study:
- To review the human gut microbiome's changes across the lifespan.
- To explore the gut microbiome's impact on aging and age-related diseases.
- To identify microbiome features associated with healthy aging and longevity.
Main Methods:
- This study is a narrative review of existing literature.
- It synthesizes findings on gut microbiome development and its role in aging.
- The review focuses on associations between microbiome composition and age-related health.
Main Results:
- Gut microbiome composition is shaped by delivery mode, diet, environment, medications, and aging.
- Microbiome features associated with diseases vary across different life stages.
- A diverse gut microbiome, producing anti-inflammatory metabolites, correlates with healthy aging globally.
Conclusions:
- The gut microbiome significantly influences aging and the risk of age-related diseases.
- Microbiome interventions targeting beneficial bacteria and metabolites hold potential for promoting health and longevity.
- Understanding the microbiome's role in aging is key to developing strategies for healthy longevity.
