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.
This is why I simply tear open the tea bags and dump them into a fine mesh stainless steel basket and set it in the cup.
I have yet to find loose leaf tea tasty enough to repeat buy but I do have 3-4 flavors of bagged tea I always keep stocked.
The biggest downside to doing my favorite bagged teas this way is it’s a pain to clean out the metal basket when I just want another cup the next day, but to me the trade off on sidestepping the microplastic issue is worthwhile
