A recent study has shown that exposure to certain chemical compounds, known as "eternal chemicals," accelerates the body's biological aging process.
According to the researchers, the issue concerns PFNA and PFAS compounds, which are widely distributed in the environment and in industry. It has been shown that high levels of these compounds in the blood are associated with signs of accelerated epigenetic aging, which are changes in DNA that reflect biological age, not the actual age of a person.
PFAS compounds are used in the production of water- and stain-resistant materials, non-stick cookware, food packaging, and fire-extinguishing foam. These compounds can enter the body through drinking water, food, and household dust, and are eliminated very slowly, accumulating in tissues.
An analysis of data from more than 300 people over the age of 50 showed that exposure to PFNA was particularly associated with accelerated biological aging in men and people aged 50 to 64. PFAS compounds also showed a negative association with signs of aging. Researchers confirm that the effect was more pronounced in some groups, suggesting possible age- and sex-related differences in sensitivity to these substances.
The researchers believe that the findings reinforce the need for stricter control over new PFAS compounds and highlight the importance of using genetic markers in assessing environmental health risks.
