Chewing gum releases significant amounts of microplastics during use, according to new research presented at the American Chemical Society meeting in San Diego. The study found approximately 100 microplastics are released per gram of gum, with some pieces releasing up to 600 microplastics per gram.

Key Findings:

• Both synthetic and natural gums contain similar amounts of microplastics
• A single piece of gum typically weighs 2-6 grams
• The most common type of plastic found was polyolefins
• People consume between 39,000-52,000 microplastic particles annually from various sources

Testing Method:

• Researchers examined 5 synthetic and 5 natural gum brands
• Test subjects chewed gum for 4 minutes
• Saliva samples were collected every 30 seconds
• Additional samples were taken at 20-minute intervals

Health Implications:

• Long-term effects of microplastic exposure remain unclear
• Recent studies suggest potential impacts on:
  • Respiratory health
  • Digestive system
  • Reproductive health
  • Possible links to colon and lung cancer

Expert Recommendations:

• Consider reducing gum consumption, especially for children
• Switching to natural gums may not reduce microplastic exposure
• Be aware that gum adds to existing microplastic exposure from other sources

The research team, led by Dr. Sanjay Mohanty from UCLA, emphasizes that their goal isn't to cause alarm but to increase awareness about microplastic exposure through everyday products. While the study hasn't yet been peer-reviewed, it highlights the need for further research into the health impacts of microplastic consumption.
