Dietary polyphenols as geroprotective compounds: From Blue Zones to hallmarks of ageing.
Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing theoretical mechanisms and observational longevity associations without primary empirical data or systematic review methodology.
PubMed 40120947 · doi:10.1016/j.arr.2025.102733
What was done
Narrative review synthesizing literature on polyphenol-rich dietary habits in five longevity hotspots (Blue Zones) and exploring how these compounds potentially influence the hallmarks of ageing and age-related disease pathways.
What was found
The abstract reports no numerical findings, effect sizes, or quantitative data. It qualitatively proposes that dietary polyphenols consumed by long-lived populations modulate evolutionarily conserved ageing mechanisms.
Why it matters
It maps observational dietary patterns of exceptionally long-lived populations onto contemporary molecular frameworks of ageing to identify translational gaps.
Limits
As a narrative review, it offers no new primary human data or systematic synthesis. The abstract contains no quantitative metrics, relies on ecological associations subject to heavy lifestyle and genetic confounding, and does not establish causal dosing or bioavailability in humans.
