Study: Gum and Bottled Water Release Microplastics

A new study led by researchers from the University of California, Los Angeles (UCLA) has found that chewing gum releases hundreds to thousands of microplastic particles into saliva, potentially contributing to microplastic ingestion. The study, presented at the American Chemical Society's meeting, involved analyzing saliva from chewing seven pieces of both synthetic and natural gum brands, revealing that a gram of gum can release an average of 100 microplastic fragments, with some pieces shedding up to 600 particles. While no direct evidence links microplastics to adverse health effects, their widespread presence in the body raises concerns, as they are suspected of causing inflammation and other health issues. Microplastics have been found in various organs, including the brain and blood. The study highlights the need for more transparency from gum manufacturers regarding ingredients and the potential health impacts of microplastic exposure. Researchers also noted that while gum is a source of microplastics, other everyday items like bottled water contribute significantly to microplastic ingestion.
