Extreme human longevity (centenarian status) is characterized by a distinct metabolic phenotype involving decreased serum tryptophan, specific remodeling of glycerophospholipids and sphingolipids, and altered gut microbiota metabolite excretion (phenylacetylglutamine and p-cresol sulfate).
This paper identifies metabolic signatures of longevity but does not offer a direct intervention. However, it suggests that maintaining healthy lipid profiles, managing inflammation, and supporting gut health (via microbiota) are biologically linked to exceptional longevity. Focus on a balanced diet that supports these metabolic pathways rather than seeking a single 'longevity pill'.
With increasing age, targeted MS profiling of blood serum displayed a marked decrease in tryptophan concentration, while an unique alteration of specific glycerophospholipids and sphingolipids are seen in the longevity phenotype.
Why this rating
Observational cohort study with a large sample size for centenarians (n=143) but small subgroups for other analyses; lacks interventional evidence.

- Centenarians exhibit enhanced cytochrome P450 (CYP) enzyme activity and anti-oxidative responses, evidenced by increased 8,9-EpETrE and decreased lipid peroxidation markers (9-HODE, 9-oxoODE).Moderate
- Longevity is associated with increased urinary excretion of phenylacetylglutamine (PAG) and p-cresol sulfate (PCS), which mirror changes in gut microbiota structure and composition.Moderate
