Is Your Chewing Gum Filling Your Body With Microplastics? A Shocking New Study Says Yes
We all enjoy chewing gum to freshen our breath or curb a snack craving. But what if this simple habit is introducing harmful microplastics into your body? A groundbreaking study published in March 2025 reveals that most commercial chewing gums contain synthetic polymers that break down into microplastics, which then mix with your saliva—and potentially your digestive system.
The Plastic in Your Gum Isn’t Just Harmless Flavor
The study, led by environmental researchers, found that many chewing gums contain synthetic materials like polyethylene, the same plastic used in grocery bags, and polyvinyl acetate, a key ingredient in glue. As you chew, these materials degrade into tiny plastic particles that enter your saliva. Beth Greenfield, a health contributor at Fortune Well, emphasized the significance of the discovery, noting that while microplastics in water and seafood have been widely discussed, gum is an overlooked source of exposure. The research team analyzed saliva samples from frequent gum chewers and consistently detected microplastics.
Why Should You Care?
The long-term health effects of ingesting microplastics are still being studied, but existing research raises concerns. Microplastics have been linked to inflammation, disruptions in gut bacteria, and potential hormone interference. Dr. Lisa Hernandez, an environmental health scientist not involved in the study, warns that microplastics are now found everywhere—from oceans to human organs. Reducing exposure where possible is a sensible precaution.
The Hidden Ingredient No One Talks About
One alarming detail is that gum manufacturers aren’t required to list “plastic” on their labels. Terms like “gum base” often hide synthetic polymers. While the study didn’t name specific brands, experts confirm these materials are industry-standard. Hernandez advises consumers to assume their gum contains plastic unless it’s labeled as natural or chicle-based, a traditional gum ingredient derived from tree sap.
What Can You Do?
Fortunately, plastic-free alternatives are available. Brands like Simply Gum and Glee Gum use natural ingredients like chicle or other plant-based materials. Consumers can also advocate for clearer labeling laws to ensure transparency about synthetic ingredients in gum. Researchers stress the importance of making informed choices to reduce plastic exposure.
The Bigger Picture
This study adds to growing evidence that microplastics have permeated our daily lives, appearing in everything from tea bags to table salt. While more research is needed to fully understand the health implications, the findings highlight the importance of small, conscious changes. Switching to natural gum alternatives is one easy way to reduce your plastic intake.
As awareness grows, so does the opportunity to make safer choices. Next time you reach for gum, consider whether the temporary freshness is worth the potential long-term risks. Your body—and the environment—might thank you for opting for a plastic-free option.
