• •PFAS chemicals, used in various products, are linked to health problems and environmental persistence.
• •The study found that PFNA and PFOSA accelerate biological aging in middle-aged men.
• •Researchers analyzed data from a US health survey and examined epigenetic markers.
• •The findings suggest the need for expanded regulations on PFAS, including newer alternatives.
• •Men may be at higher risk due to lifestyle factors, such as smoking, which can compound the damaging effects of these pollutants.
• •Individuals can limit exposure by reducing consumption of packaged foods and avoiding microwaving fast-food containers.

A recent study found that specific PFAS chemicals, known as 'forever chemicals', accelerate biological aging, particularly in middle-aged men. Researchers analyzed data from a US health survey, measuring PFAS levels and epigenetic markers in blood samples. They discovered a strong link between higher levels of PFNA and PFOSA and faster epigenetic aging in men aged 50-64. The study suggests that newer PFAS alternatives may not be low-risk replacements and calls for expanded regulations to include them.
