Chewing gum has long been a favorite habit for freshening breath, reducing stress, and aiding concentration. However, recent research has unveiled a concerning aspect of this seemingly harmless activity: the release of microplastics into the human body. A new study has found that chewing a single piece of gum may expose individuals to hundreds or even thousands of microplastic particles, which are then potentially ingested.
What Are Microplastics?
Microplastics are tiny plastic particles less than five millimeters in size. They are commonly found in oceans, air, food, and even human tissues. While their environmental impact has been widely studied, recent findings suggest that microplastics are also entering the human body through everyday activities such as chewing gum.
Scientists have discovered that both synthetic and natural chewing gums release significant quantities of microplastics when chewed. The study revealed that one gram of chewing gum could release an average of 100 microplastics, with some brands shedding as many as 637 microplastics per gram. Given the popularity of gum chewing, this raises concerns about long-term exposure to these particles.
How Microplastics Enter the Body
When chewing gum, the mechanical process of mastication causes friction, breaking down the gum’s structure and potentially releasing plastic particles. These microplastics mix with saliva and may be swallowed, making their way into the digestive system. Over time, repeated exposure could lead to the accumulation of microplastics in the body.
Potential Health Risks of Microplastic Ingestion
The health implications of ingesting microplastics are still under investigation, but emerging evidence suggests links to several health issues. Some research has indicated that microplastics have been detected in human blood, lungs, and even arteries. Scientists suspect that long-term exposure to microplastics may contribute to a range of health concerns, including:
-
Cardiovascular Issues: Microplastics have been found in the arteries of some individuals, raising concerns that they may contribute to an increased risk of strokes and heart attacks.
-
Digestive Problems: Since microplastics can accumulate in the gut, they may disrupt normal digestion and impact gut health.
-
Hormonal Disruptions: Some microplastics contain chemicals known as endocrine disruptors, which can interfere with hormone production and regulation.
-
Respiratory Concerns: Microplastics present in the air have been linked to lung issues, and ingesting them may pose additional respiratory risks.
-
Cancer Risks: Some studies suggest that long-term exposure to microplastics may contribute to an increased risk of certain cancers, although more research is needed.
How to Reduce Microplastic Exposure from Chewing Gum
While completely avoiding microplastics is challenging due to their widespread presence in the environment, there are ways to minimize exposure, particularly from chewing gum:
-
Choose Natural Alternatives: Opt for chewing gums made from natural ingredients like chicle, which is derived from tree sap rather than synthetic materials.
-
Chew Less Frequently: If you regularly chew gum, consider reducing the frequency to limit microplastic ingestion.
-
Chew the Same Piece Longer: Instead of chewing multiple pieces throughout the day, extending the duration of a single piece may reduce microplastic intake.
-
Proper Disposal: Avoid littering gum, as improperly discarded pieces contribute to environmental microplastic pollution.
Future Research and Concerns
While the presence of microplastics in chewing gum is concerning, scientists are still investigating the long-term health effects. Research is ongoing to determine whether microplastics can accumulate in vital organs and what impact they may have on human health over time. Given the potential risks, experts advise taking precautionary measures and staying informed about new scientific findings on microplastics.
As microplastic exposure becomes a growing concern, individuals must be mindful of their everyday habits. Being aware of potential sources of microplastics, including chewing gum, and making informed choices can help reduce exposure and promote better long-term health.
