☕ Are tea bags toxic? This Short dives into the science behind micro- and nano-plastics leaching from popular tea bags—yes, even that soothing cup of Earl Grey. You’ll learn:
• How many plastics? Up to 11.6 billion micro-plastics can burst from one nylon bag at 95 °C.
• Health path: 2024 UAB researchers showed these particles cross intestinal cells in vitro, pointing to possible bloodstream exposure.
• Brewing hacks: Pre-rinse or keep steep time under 180 s and you slash plastic counts by about 30 %.
• Safer options: Loose-leaf + stainless infuser or third-party–verified plastic-free paper bags preserve flavor while ditching hidden polymers.
• Big picture: WHO’s 2019 review says current microplastic exposure is unlikely to pose acute harm, but they call for more data—so reduce where you can.
