Growing global concerns about plastic contamination in food and the environment have prompted research into potential ways the body can mitigate the effects of microplastics. A recent study suggests that certain fermented foods may help the body eliminate these tiny plastic particles, not just reduce their health impacts.
According to a report in New York Post, the study focused on kimchi, a popular Korean food rich in probiotics. Researchers at the World Institute of Kimchi analyzed the beneficial bacteria strains found within it.
The research team isolated a strain of lactic acid bacteria known as Leuconosterv mesenteroides CBA3656 and studied its ability to bind to nanoscale plastic particles, specifically those derived from polystyrene. This research is particularly relevant as microplastics are increasingly found in the human food chain and their long-term health effects are still being investigated.
Laboratory experiments on mice showed that the group consuming this bacterial strain excreted more than twice the amount of plastic particles in their feces compared to the other group. This suggests the bacteria may contribute to the removal of these particles from the digestive system.
Researchers explained that probiotic-rich foods, used for centuries to support gut health, may have an additional ability to combat the effects of plastic pollution by binding to harmful particles and removing them from the body.
Micro- and nanoscale plastic particles are emerging contaminants of increasing concern, as they can accumulate in various organs such as the liver and brain, and have been linked to health issues including inflammatory bowel disease and bacterial imbalances.
While the results are promising, researchers emphasize that this study is still in its early stages. Further research is needed to confirm its effectiveness in humans and to determine the most beneficial quantities and types of fermented foods. The findings highlight the potential for dietary interventions to address environmental health challenges.
These findings open the door to new possibilities for using food as a natural means of helping to address one of the most pressing pollution challenges of our time.
