What is the new link found between forever chemicals and health conditions?

A recent study found that exposure to "forever chemicals" like PFOS and PCBs is linked to an increased likelihood of being diagnosed with multiple sclerosis (MS).

How much does exposure to PFOS and PCBs increase MS risk?

People with the highest concentrations of PFOS and PCBs had approximately twice the odds of being diagnosed with MS compared to those with the lowest concentrations.

Are 'forever chemicals' still present in products in the US?

Yes, while PCBs were banned in 1979, "forever chemicals" (PFAS) are still used in various products, from fast food wrappers to smart watch bands.

MS Risk Doubles with 'Forever Chemical' Exposure

New research has uncovered a significant association between exposure to pervasive environmental toxins and the development of multiple sclerosis (MS). The study, published in Environment International, identified specific "forever chemicals," namely perfluorooctane sulfonic acid (PFOS) and polychlorinated biphenyls (PCBs), as being linked to higher odds of an MS diagnosis. Individuals with the highest detected levels of these substances demonstrated roughly double the risk compared to those with the lowest concentrations.

This groundbreaking study analyzed blood samples from individuals recently diagnosed with MS and compared them to a control group. Researchers observed that increased exposure to a combination of chemicals corresponded with a higher probability of developing MS, even after accounting for known lifestyle and genetic risk factors. Furthermore, a complex interaction was noted between genetic predispositions and chemical exposure, with one gene variant unexpectedly increasing MS risk in the presence of high PFOS levels.
