UAB research has characterized in detail how polymer-based commercial tea bags release millions of nanoplastics and microplastics when infused. The study shows for the first time the capacity of these particles to be absorbed by human intestinal cells, and are thus able to reach the bloodstream and spread throughout the body.
I remember reading something like this about a decade ago. It’s why I much prefer loose leaf tea and use a metal sieve/strainer.
I have a French press. Think I’ll start brewing my tea in that now. Thanks
