Chewing Gum: A Hidden Source of Microplastics
Recent research from the University of California, Los Angeles (UCLA) has uncovered that chewing a single piece of gum can release hundreds to thousands of microplastic particles into the mouth, which are subsequently swallowed. This finding adds to growing concerns about the prevalence of microplastics in our daily lives.
How Many Microplastics Are Released?
The study analyzed ten popular gum brands in the United States, comprising both synthetic and natural varieties. Participants chewed each piece for four minutes, during which saliva samples were collected and examined for microplastic content. On average, one gram of gum released approximately 100 microplastic particles, with some samples emitting up to 637 particles per gram. Considering that a typical piece of gum weighs between two to six grams, this could result in the ingestion of up to 3,000 microplastic particles per piece. Notably, 94% of these particles were released within the first eight minutes of chewing.
What Are These Microplastics Made Of?
Both synthetic and natural gums were found to release similar amounts of microplastics, predominantly composed of polymers such as polyolefins, polyethylene terephthalates, polyacrylamides, and polystyrenes. These substances are commonly used in everyday plastic products, raising concerns about their ingestion through gum chewing.
Health Concerns: What Does This Mean for You?
The health effects of ingesting microplastics are unclear, but studies link them to hypertension, diabetes, and stroke. To minimize exposure, experts suggest reducing the frequency of chewing new pieces of gum and considering alternatives.
This study underscores the importance of being mindful about the products we consume and their potential impact on our health. As research continues, individuals may want to reconsider their chewing habits in light of these findings.
