Billions of nanoplastics from tea bags might pose severe health risks, including fertility issues and a heightened risk of various cancers, health experts caution.
When someone uses tea bags, they might unknowingly ingest microplastics that could trigger numerous health disorders. Researchers at the University of Barcelona, Spain, highlighted significant concerns with their findings.
Their research tested tea bags made from commonly used plastic polymers. The results showed that tea bags composed of polypropylene released 1.2 billion microplastic particles into a single drop of hot water. Tea bags from cellulose and nylon-6 released 135 million and over 8 million particles, respectively.
These microplastics release potentially carcinogenic chemicals when steeped in hot water. A similar Canadian study corroborated these alarming results.
Furthermore, a recent study revealed that dipping tea bags in hot water releases countless toxic microplastics. Scientists from Universitat Autonoma in Barcelona emphasized that these could introduce billions of harmful particles into the body.
Microplastics pervade food containers and saucepans daily and can leach into food, drinks, and air. Subsequent tests have detected high concentrations of these particles in human breast milk, blood, saliva, and feces.
Additionally, researchers at the University of California, San Francisco, linked airborne microplastic particles to increased colon cancers among young people. Their review of 3,000 studies suggested these particles, once inhaled, might migrate from the lungs into the bloodstream.
Further studies associate microplastic exposure with potential structural alterations in the colon, escalating cancer risks. In a Chinese study, lab mice exposed to chronic levels of microplastics showed significant damage to colon walls. Other findings noted a reduction in protective mucus production in the colon due to microplastics, potentially explaining a global decline in fertility rates.
Another disturbing revelation from 2024 research showed that gut cancer cells proliferated faster following contact with microplastics.
