Revealed: Chewing Gum Can Release Thousands of Microplastics in Your Mouth, New Study Warns!
Chewing gum is a popular treat enjoyed by many, but recent research indicates that it may harbor hidden dangers. The latest findings suggest that chewing gum can release hundreds of microplastics—or tiny plastic particles—into saliva. While the exposure from gum is relatively small compared to other sources, it’s wise to be aware of these findings and consider moderating your gum consumption.
Microplastics are increasingly found in our environment, from the air we breathe to the food we consume. Just when you thought you knew what was in your favorite chewing gum, a study revealed that these tiny plastic particles are present in this common product as well.
Presented recently at a spring meeting of the American Chemical Society (ACS), this study has not yet been peer-reviewed, but it raised concerns about the potential risks of microplastics. Researchers found that both natural and synthetic gums release similar amounts of microplastics into the saliva, prompting experts to recommend limiting gum intake.
Understanding Microplastics
Microplastics come from polymers—chemical compounds known for their flexibility—that do not break down easily. When inhaled or ingested, these minuscule particles can accumulate in our bloodstream and organs, leading to concerns over their long-term effects on human health. While scientists are still unraveling the complexities of microplastic impacts, early evidence suggests they could be linked to:
- Inflammation
- DNA damage
- Metabolic disorders
- Increased risk of cardiovascular diseases
Key Findings from the Study
With multiple studies showcasing how microplastics emerge from consumer products, the researchers of this current study were keen on identifying chewing gum as another potential source. The researchers tested ten popular chewing gums sold in the United States, categorizing them as either natural or synthetic (specific brands were not disclosed).
The participants engaged in a series of rigorous tests to quantify the microplastics released:
- They rinsed their mouths with deionized water to establish a baseline of microplastics.
- Participants chewed each type of gum for four minutes, and some extended to an additional 20 minutes.
- Researchers collected saliva samples before, during, and after chewing.
The results were surprising. One gram of gum could potentially release up to 637 microplastics. With an average piece of gum weighing between two and six grams, this translates to a considerable number of microplastics per serving. The average size of these particles measured 82 micrometers, with about 56% of them being smaller than 50 micrometers.
Interestingly, the findings indicated that around 94% of microplastics were released during the first eight minutes of chewing, plateauing after that point.
Why Do Gums Contain Microplastics?
The presence of microplastics stems from the polymers which impart chewability and elasticity to gum. In natural gums, polyolefins (often used in food packaging) accounted for a significant percentage of the identified particles. On the other hand, synthetic gums included higher levels of polymers such as PET and polystyrenes, alongside other petrochemical substances.
Dr. Sanjay Mohanty, the principal investigator of the study, highlighted a critical distinction: in chewing gum, the item itself is composed of plastic, contrasting with food items where microplastics are primarily contaminants.
The Health Risks of Microplastics
Research has identified microplastics throughout various human body systems, including the lungs, bloodstream, and even organs like the brain and intestines. Although limited, studies indicate a correlation between microplastics and various health issues, such as:
- DNA damage
- Oxidative stress
- Metabolic dysfunction
- Organ impairment
Excessive accumulation of microplastics in the digestive system may heighten the risk of inflammatory bowel disease, and those found in the bloodstream could be associated with a greater risk of cardiovascular conditions, alongside possible issues with fertility and neurotoxicity.
Should You Stop Chewing Gum?
Experts suggest that while everyday exposure to microplastics is inevitable, the amount found in chewing gum remains relatively low compared to items like tea bags. Dr. Lisa Patel recommends moderating gum consumption, especially considering that most microplastics are released within the first few minutes of chewing.
To minimize environmental impact, it’s essential to dispose of gum correctly—preferably in a trash can rather than on the ground to prevent contamination of the ecosystem.
In summary, while removing all plastics from our lives may not be feasible, experts advocate for reducing plastic consumption where possible, including the choice of chewing gum. “The sooner we minimize our plastics use—keeping it only to the uses where we really don’t have good alternatives—the better off we’ll all be,” Dr. Patel concluded.
