A study which came out earlier today has shown that plastic tea bags release a ton of “microplastics” and “nanoplastics” which if you didn’t know, is basically microscopic pieces of plastic that your body can’t digest properly. It’s unknown as of right now just what kind of damage microplastics can do, but it’s reasonable to assume that it ain’t great. The study also looked at loose-leaf tea, and found no evidence whatsoever of the plastic in there, so if you steep your tea the more traditional way, you’re totally safe.
I’m not going to stop drinking tea the same way I always have because of this though. Although that’s probably because I don’t drink tea!
