Study Shows Human Gut Bacteria Can Absorb Toxic 'Forever Chemicals'

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are known as 'forever chemicals' due to their persistence in the environment. Some human gut bacteria have been found to absorb and store PFAS, potentially protecting our health. Researchers discovered that certain gut bacterial strains can absorb PFAS and store them inside their cells, reducing the toxic effects. The study identified 38 bacterial strains capable of absorbing forever chemicals, with Bacteroides uniformis being one of the most effective. Experiments with Escherichia coli revealed mechanisms that could enhance bacteria's ability to absorb PFAS. Tests on mice showed that bacteria implanted in their guts could absorb and excrete PFAS. The findings suggest the possibility of developing ways to remove PFAS from our bodies to reduce their harmful effects.

PFAS are present in various products and have become widespread in manufacturing processes. The health impacts of PFAS are still not fully understood but have been linked to kidney damage and other health issues. The potential use of probiotic supplements to enhance gut bacteria and aid in removing PFAS from our bodies is being considered. The study highlights the need to address the presence of PFAS in our bodies and their impact on human health.
