Summary
This narrative review examines current evidence on the anti-ageing potential of dietary polyphenols, synthesising proposed mechanisms of action including antioxidant activity and modulation of cell signalling pathways implicated in ageing. The authors likely discuss polyphenol-rich food sources and their effects on oxidative stress, inflammation, and cellular dysfunction markers. However, the authors note that clinical translation of these mechanistic findings to human longevity remains limited, and evidence from controlled dietary intervention trials in humans is sparse.
Regional applicability
The mechanistic insights are applicable to UK nutritional science and public health messaging around plant-rich diets, though UK dietary guidelines already emphasise vegetable and fruit consumption. Direct clinical applicability depends on whether the polyphenol doses examined in mechanistic studies align with realistic dietary intake levels.
Key measures
Polyphenol bioactivity measured through oxidative stress markers, inflammatory cytokines, cellular senescence, and age-related signalling pathway modulation in in vitro and animal models
Outcomes reported
The review synthesises evidence on molecular mechanisms by which dietary polyphenols may attenuate oxidative stress, inflammation, and age-related cellular dysfunction. Specific bioactivity pathways including antioxidant and cell signalling mechanisms are examined.
