Microplastics may spread from gut to brain, finds study
Advertisement
In a study published in Environmental Health Perspectives, researchers examined how consuming microplastics in amounts similar to those found in our environment affected mice.
Microplastics, found in various substances, are ubiquitous in the environment, from soil to food and water. Upon ingestion, they traverse the digestive tract and can enter the bloodstream through the gut lining. These particles can circulate throughout the body, potentially reaching the blood-brain barrier, which normally shields the brain from harmful substances. Under certain conditions, smaller microplastic particles may breach this barrier, accumulate, and possibly induce adverse effects.
In the study, researchers sought to understand the impact of different types of microplastics on various organs in mice. They defined microplastics as plastic particles smaller than 5 millimeters and aimed to replicate human exposure levels. Mice were orally fed varying amounts of polystyrene or mixed polymer microspheres. After ingestion, the researchers examined serum, brain, liver, kidney, and colon tissues to assess the presence of microplastics and any resulting effects.
