Summary
A new study from Spain’s Autonomous University of Barcelona reveals that tea bags made from nylon, polypropylene, and cellulose release billions of micro- and nanoplastic particles when steeped in boiling water.
These particles, which can enter human intestinal cells, may pose health risks, potentially affecting the digestive, respiratory, endocrine, and immune systems.
Researchers urge regulatory action to mitigate plastic contamination in food packaging.
Consumers are advised to use loose-leaf tea with stainless steel infusers or biodegradable tea bags to minimize exposure.
Cellulose isn’t plastic though, it’s the sugar that makes up plant cell walls, like wood. Cotton fibers are 90% cellulose https://en.wikipedia.org/wiki/Cellulose
I’m confused why they included cellulose without clarifying that it’s not a petrochemical, unless cellulose micro and nano particles are also an issue now. Maybe I should read the original study…
They close the bags with a dot of plastic based glue so it doesn’t open
What I meant to say is that the cellulose is coated with plastic. I learned this from another post in the same thread.
