PFAS and Environmental Health

A new study in the journal Frontiers in Aging, based on 326 U.S. adults from the National Health and Nutrition Examination Survey, finds that higher blood levels of two 'forever chemicals'—perfluorononanoic acid (PFNA) and perfluorooctanesulfonamide (PFOSA)—are associated with faster DNA‑based biological aging in men aged 50 to 64, but not in women. Chinese researchers used epigenetic clocks, which read chemical changes on DNA, to estimate cellular aging and found these two PFAS compounds, detected in 95% of participants, were most strongly linked to accelerated aging. The work, led by Dr. Xiangwei Li of Shanghai Jiao Tong University School of Medicine, does not prove PFAS cause aging but suggests midlife may be a particularly vulnerable period when exposures and lifestyle factors like smoking interact with age‑related stress. Li told Fox News Digital that people should not panic but can reasonably reduce exposure by checking local water reports, using certified filters, and limiting stain‑ and grease‑resistant products while broader PFAS regulation and cleanup remain crucial. The study adds to mounting evidence that ubiquitous PFAS contamination in U.S. water, soil and consumer goods may have systemic long‑term health impacts beyond cancer and cholesterol, including on how quickly our bodies age.
