Forever Chemicals Accelerate Aging in Men, Study Finds

A new study from Jiao Tong University in Shanghai suggests that PFAS chemicals, known as “forever chemicals” due to their persistence in the environment, may accelerate biological aging, particularly in middle-aged men. PFAS are widely used in various products, such as non-stick coatings, waterproof fabrics, and food packaging, and contamination from these chemicals is increasingly detected in the environment and organisms. The study, published in the journal “Frontiers in Aging,” analyzed data from 326 men and women, examining PFAS concentrations in their blood and DNA methylation, an epigenetic marker of aging. The results showed that higher concentrations of two specific PFAS, PFNA and PFOSA, were associated with faster epigenetic aging in men aged 50-64, but not in women. Researchers explain that middle age is a “sensitive biological window” where the body is more vulnerable to age-related stressors. Additionally, they suggest that men may be at greater risk due to lifestyle factors, such as smoking, which can exacerbate the harmful effects of PFAS. The study highlights the need for further research on the health and aging effects of PFAS, as well as the implementation of regulatory measures to limit exposure to these substances. The authors emphasize that regulatory authorities should expand the scope of restrictions beyond “legacy” PFAS, including newer substances used in emerging technologies, such as artificial intelligence data centers. Overall, the research adds to the growing concern about the potential health impacts of PFAS and underscores the importance of proactive action to reduce exposure to these “forever chemicals.” The study provides strong evidence that PFAS may play a significant role in the aging process, especially in men, and that reducing exposure to these substances may contribute to improved health and longevity.
