Four-week plant-forward diets linked to younger-looking biology in seniors
A 104-person study (aged 65–75) found that four weeks of dietary changes, especially plant-forward diets with about 70% plant protein, lowered biological age as judged by 20 health biomarkers in three of four diet groups; a high-fat omnivorous diet showed no meaningful change. The results suggest short-term dietary shifts can affect aging biomarkers, but are preliminary.
