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.
Source? For example the clipper website says they don’t use plastic, how do you know it still has plastic? https://www.clipper-teas.com/tea-talk/plastic-free-tea-bags/
Read that link carefully, there’s a lot of flowery language but they do not say their bags are plastic-free.
There is also this page that says which tea brand don’t use plastics with sources to the announcement.
Unless they were talking about PLA plastics which from a (very) quick search seems to pose no risk
This is the summary blurb at the top of the article.
I would be very skeptical of ingesting something and believing it harmless if the study finds that it eventually breaks down in the environment, let alone it’s clearly funded by a company with ‘bioplastics’ in the company name.
I have more bad news: [https://www.sciencedirect.com/science/article/pii/S0048969724007307](Are bioplastics safe? Hazardous effects of polylactic acid (PLA) nanoplastics in Drosophila)
Fixed the link for anyone who wanted to skim this study
thanks!
Your study is from 1/4/24 the one I linked is from 26/6/24
Or am I just being a muppet here?
Silly me. Glad that is resolved.
National institute of health: https://pmc.ncbi.nlm.nih.gov/articles/PMC10389239/ If a company makes a claim that their bags are 100% plastic free, that is great. Just don’t assume that paper bag = no plastic.
By the way: the clipper website says they use PLA, which is a plastic - just not a petroleum plastic. Its health effects are being investigated.
