Exposure to perfluoroalkyl and polyfluoroalkyl (PFAS)—“forever chemicals” often found in non-stick cookware, food packaging and contaminated water—may cause menopause to occur two years earlier in women, according to a new study published in the Journal of Clinical Endocrinology & Metabolism. University of Michigan scientists tracked more than 1,100 women for an average of 17 years and found that those with higher levels of the chemical in their blood experienced menopause an average of two years earlier than those with lower levels. “Even menopause a few years earlier than usual could have a significant impact on cardiovascular and bone health, quality of life and overall health in general among women,” says co-author Sung Kyun Park.
