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.

    No it’s not, because I use a stainless steel capsule and loose leaf tea, which is superior in every way (even if microplastics weren’t an issue).

    If you don’t make your tea like this, do yourself a favor and upgrade to some quality loose leaf!

    OMG. That’s a good way to start the new year. Now my daily tea is going to be filled with guilt and worry.

      Just buy paper tea bags or loose leaf tea. The article is talking about those stupid nylon “pyramid” tea bags.

      You can switch to loose leaf. I thought loose leaf sucked because the tea bits always got in it. Then I found a metal filter that has like, 180nm holes in it. Extremely fine mesh.

      I use it more than paper tea bags now!

    Consumers are advised to …

    Consumers are advised to check whether tea bags in their region are even made of these materials.

    Edit: Also, “billions”? The cookie warning is borked on the foodandwine.com article so I can’t read it but: https://www.dpa-international.com/trends-and-features/urn:newsml:dpa.com:20090101:250109-99-540705/ “Tea bags releasing ‘millions’ of microplastics into tea, study shows” - where does that difference come from?

      From the article:

      To come to this conclusion, the team tested tea bags made from nylon-6, polypropylene, and cellulose, all typical packaging for teas. They found that when brewing tea, “polypropylene releases approximately 1.2 billion particles per milliliter, with an average size of 136.7 nanometres; cellulose releases about 135 million particles per milliliter, with an average size of 244 nanometres; while nylon-6 releases 8.18 million particles per milliliter, with an average size of 138.4 nanometres.”

    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
