Chewing Gum Warning: Study Finds Hundreds of Microplastics Released in Every Bite

A new study has found that chewing gum releases hundreds of tiny plastic particles, known as microplastics, directly into a person’s mouth. Researchers from the University of California, Los Angeles (UCLA) discovered that a single gram of gum can release up to 600 microplastic fragments, raising concerns about an overlooked source of plastic exposure.

The study analyzed different gum brands, including both synthetic and natural varieties. The results showed that microplastics were present in both types, with most of the particles being released within the first eight minutes of chewing. Given that a standard stick of gum weighs around 1.5 grams, frequent gum chewers could be unknowingly ingesting thousands of microplastic particles each year.

Microplastics have been detected in human blood, lungs, and even the brain, sparking concerns about potential health risks. However, researchers noted that while this study highlights another source of microplastic exposure, there is no direct evidence linking gum-chewing to specific health issues.

Beyond health concerns, improperly disposed chewing gum also contributes to plastic pollution. Scientists are calling for greater transparency from manufacturers regarding gum ingredients and urging consumers to dispose of gum responsibly.

The findings were presented at the American Chemical Society meeting in San Diego and are currently under peer review for publication.
