    1/ Various claims have been made regarding alleged harms of excessive seed oils consumption:

    i) Accelerated aging, and premature death
    ii) Increasing cholesterol levels and cardiovascular disease CVD risk
    iii) Promoting systemic inflammation
    iv) Increased risk of diabetes
    v)…

    End Note:

    Aging clocks are mostly a proxy (surrogate endpoint) for the actual endpoint of interest, which is lifespan itself (mortality data). Relying solely on mortality data would delay the field by several decades.

    Since aging clocks were not specifically designed to…

    4/ Results validate some longevity interventions, but mostly indicate a wide gap in the systemic understanding of other interventions and the reliability of "single aging clock approaches" and animal data in assessing longevity outcomes in humans.

    Metformin has long been of…
