Lynda Frassetto – Potential anti-aging effects of a Paleo diet – AHS19

Paleo diets, which may be low in dietary acids such as phosphate and high in base precursors such as citrate and malate, may help slow metabolic processes associated with aging. These include:
1) slowing progressive acid-induced damage to the kidneys, which would help preserve the kidneys ability to excrete acid and minimize systemic acidosis;
2) avoiding the downregulation of klotho, a membrane and soluble factor associated with aging that decreases with constant high dietary phosphate intake and FGF-23 production; and
3) potentially improving telomerase activity to help maintain telomere length, another factor associated with longer lifespan.
Although the present data is mainly from studies in invertebrate and small animal models, extrapolation of these results, as well as some associated results in human studies, suggests that low acid diets (which includes some Paleo diets) may be a factor in living longer.
