Some Teabags Release Millions Of Microplastics That Could Enter Intestinal Cells

 You might think of tea as a comforting, soothing ritual. But, scientists at Universitat Autònoma de Barcelona (UAB) have made a startling discovery — infusing tea through commercial tea bags might be releasing billions of nanoplastics and microplastics into your cup.

 Recent research from the Mutagenesis Group in the UAB Department of Genetics and Microbiology highlights how polymer-based tea bags release microplastics and nanoplastics (MNPLs) during brewing.

 For the first time, the study has shown that these particles can be absorbed by human intestinal cells, potentially entering the bloodstream and spreading throughout the body.

 Food packaging is a leading contributor to micro and nanoplastic pollution. Humans are primarily exposed to these particles through inhalation and ingestion.

 This new study focuses on the significant release of MNPLs from commercially available tea bags when used to prepare an infusion.

 The researchers discovered alarming levels of contamination:

 Polypropylene released around 1.2 billion particles per milliliter, with an average size of 136.7 nanometers.

Cellulose released 135 million particles per milliliter, averaging 244 nanometers.

Nylon-6 released 8.18 million particles per milliliter, averaging 138.4 nanometers.

These findings underline the importance of identifying and reducing plastic exposure through everyday items, like tea bags.

 To characterize these particles, the researchers employed advanced analytical techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), and nanoparticle tracking analysis (NTA).

These methods allowed the team to examine the structure, size, and behavior of the particles in detail.

 “We have managed to innovatively characterize these pollutants with a set of cutting-edge techniques, which is a very important tool to advance research on their possible impacts on human health,” explained UAB researcher Alba Garcia.

 For starters, tea is packed with antioxidants, which help your body fight off harmful free radicals. These antioxidants can reduce the risk of chronic diseases like heart disease and certain cancers.

Plus, different types of tea, like green, black, and oolong, have unique compounds that support brain health, potentially improving focus and reducing the chances of developing conditions like Alzheimer’s.

 Sipping on a cup of tea can be a simple way to boost your overall health and keep your mind sharp.

 Another great perk of drinking tea is that it can help with relaxation and stress relief. Herbal teas like chamomile and peppermint are well-known for their calming effects, making them perfect for unwinding after a long day.

 Even caffeinated teas, when enjoyed in moderation, can provide a gentle energy boost without the jitters that coffee might cause.
