Emerging research also suggests a possible link between microplastics and the development of cancer and reproductive health issues, with studies indicating accelerated cancer cell spread and reduced sperm motility upon exposure.
A new study has raised serious health concerns over the use of plastic tea bags, warning that a single cup of tea brewed with one can release up to 11.6 billion microplastic particles. Dr. Mark Hyman, citing research from the journal ACS Publications, noted that these tiny plastic fragments—smaller than 5mm—are increasingly linked to potential health risks, including cancer.
The findings, supported by a Chemosphere study, showed polypropylene tea bags release 1.2 billion nano-sized particles per milliliter when brewed, while nylon varieties emitted 8.18 million per milliliter. “If you are a tea drinker, use an organic loose leaf tea and steep it,” Hyman advised, emphasizing the risk of long-term microplastic exposure.
He urged consumers to avoid tea bags made with BPA, phthalates, and polypropylene. “Look for tea bags made from organic hemp, cotton, or plant fibres instead,” he said, highlighting the growing concern among scientists over how these particles may disrupt cellular function.
