Dietary Lipid May Rejuvenate Mitochondria and Slow Aging

Aging appears to slow mitochondria partly because the lipid phosphatidylcholine declines; dietary supplementation restored mitochondrial function in worm models, and in human tissue higher phosphatidylcholine levels aligned with healthier aging, with notable sex differences around menopause. The study suggests boosting this lipid could counter mitochondrial aging and warrants further molecular study; published in Nature Communications.
