A recent study presented at the American Chemical Society's spring meeting has revealed that chewing gum can release significant amounts of microplastics into saliva. The research indicates that, on average, each gram of gum can produce around 100 microplastic particles, with some types releasing as many as 600 particles per gram. This study examined both synthetic and natural chewing gums, finding that both types contained similar levels of microplastics, which surprised researchers who initially expected higher concentrations in synthetic varieties.
The principal investigator, Sanjay Mohanty from UCLA, emphasized that the study aims not to alarm the public but to highlight a potential source of microplastic exposure. While the long-term health effects of microplastics are still uncertain, existing research suggests they may pose various health risks, including potential impacts on respiratory, digestive, and reproductive health.
Microplastics have become pervasive in everyday life, often entering the human body through food and drink, with previous estimates suggesting individuals consume tens of thousands of particles annually. This study adds chewing gum to a growing list of potential sources of microplastic exposure.
Experts, including Tracey Woodruff from UCSF and Dana Hunnes from UCLA Health, acknowledge the findings are concerning, particularly since many people swallow saliva while chewing gum. They suggest that reducing or eliminating gum consumption could be a straightforward way for individuals to lower their microplastic intake, particularly for children whose developing bodies may be more susceptible to potential harm. The study underscores the importance of continued research into the effects of microplastics and their presence in various consumer products.
