Age-related gut dysbiosis triggers chronic low-grade inflammation (inflammaging) and innate immune activation, which drives age-related degenerative pathologies and reduces longevity.
Your gut health is not determined by your birth year but by your biological age and lifestyle. Dysbiosis (an imbalance of gut bacteria) triggers inflammation that accelerates aging. To maintain longevity, focus on dietary patterns that support a diverse microbiome and avoid factors like high-glycemic diets or excessive antibiotic use that promote dysbiosis.
Gut dysbiosis can trigger the innate immune response and chronic low-grade inflammation, leading to many age-related degenerative pathologies and unhealthy aging.
Why this rating
Strong evidence from multiple model organisms (C. elegans, Drosophila, mice, killifish) showing causal links between microbiota transfer and aging phenotypes.

More from this paper
- Specific gut bacteria extend host lifespan by interacting with host nutrient signaling pathways (IIS and mTOR), and this extension is lost if these pathways are disabled.Good
- Short-chain fatty acids (SCFAs) like butyrate have dual effects on aging: they can promote healthy aging (e.g., via HDAC inhibition) but also contribute to pathology (e.g., neuroinflammation in Parkinson's models) depending on context.Good
