Gut Microbes May Help Combat Toxic Chemicals

Recent research indicates that gut bacteria might aid in protecting people from harmful, long-lasting chemicals often referred to as “eternal chemicals.” Scientists from the University of Cambridge have found that specific gut microbes may assist in eliminating toxic PFAS (per- and polyfluoroalkyl substances) from the body, based on studies conducted on mice.

The US Environmental Protection Agency describes PFAS as widely used chemicals that do not break down easily over time. Dr. Kiran Patil, a senior author of the study from the MRC Toxicology Unit at Cambridge, stated that certain types of human gut bacteria are particularly effective at absorbing these harmful substances from various concentrations in the environment.

Interestingly, there are over 4,700 PFAS chemicals currently in use. While some can be expelled through urine quickly, others can persist in the body for years, raising concerns about their long-term effects.

Dr. Anna Lindell, a researcher involved in the study, noted that exposure to PFAS is widespread, affecting everyone through contaminated water and food. She expressed concerns about how PFAS, once deemed safe, have become recognized for their potential hazards over time. “The slow recognition of their toxicity is alarming,” she remarked.

Currently, Patil and Lindell are exploring the possibility of developing probiotic supplements to enhance the population of beneficial microorganisms in our bodies, potentially offering protection against PFAS exposure. Until such solutions are available, they suggest avoiding cooking utensils coated with PFAS and using reliable water filters to reduce potential exposure.

As awareness grows regarding the dangers of these chemicals, there seems to be a mix of hope and concern. While methods to mitigate exposure continue to be explored, the challenge remains daunting, particularly considering the pervasive nature of PFAS in our environment.
