An international research team has proven that tea bags release a considerable amount of micro and nano plastics into the drink during brewing. Health risks are significant. Because these tiny particles are capable of penetrating even the nucleus of intestinal cells. Here are the 3 teas that could seriously harm your health, according to these scientists.
Teas release billions of particles
A recent study, which Spanish scientists from the Faculty of Biosciences of the Autonomous University of Barcelona conducted, sifted through different types of bagged teas.
A team of scientists then discovered that these also release billions microplastics and nanoplastics in the infusion that our body ends up absorbing.
Previous studies have already shown how micro and nano plastics can easily enter our bodies. And this, through the foods and liquids we ingest. They have toxic effects on health. Such as stunted growth and metabolic alterations. But also consequences on the immune and nervous systems.

In addition, the study also showed that they can generate a series of pathological conditions. But also from oxidation to inflammation, causing multiple diseases. And in particular cancer, thrombosis, atherosclerosis, inflammatory bowel diseases et neurodegenerative diseases.
Watch out for these 3 compounds!
Scientists from the University of Barcelona therefore examined certain types of bagged teas made from:
– nylon-6 polymers,
– polypropylene
– cellulose.
They then observed that these compounds released a large number of particles. Specifically, they found that polypropylene releases approximately 1.2 billion particles per milliliter. Cellulose releases approximately 135 million per ml. While nylon-6 releases 8.18 million per ml.
A series of advanced processes for the study of these tea bags
To define the different types of particles present in bagged teas, a series of advanced analytical processes were used. “We have succeeded in characterizing these pollutants in an innovative way. Thanks to a set of cutting-edge techniques. They represent a very important tool for advancing research into their possible impacts on human health,” Professor García-Rodríguez then declared in a press release.

These results therefore highlight the need for continued research into the effects that chronic exposure can have on human health.
“It is essential to develop standardized testing methods to assess micro- and nanoplastic contamination released from plastic materials in contact with food and to formulate regulatory policies to effectively mitigate and minimize this contamination.
As the use of plastic in food packaging continues to increase, it is essential that we do so. Fight against contamination by micro and nanoplasticss to ensure food safety and protect public health is vital”the researchers then concluded.
