New Study Reveals Hot Tea Contains the Highest Levels of Microplastics.

University of Birmingham Study on Microplastics in Hot Tea

According to TSN.ua: A study from the University of Birmingham has identified hot tea as the drink with the highest concentration of microplastics among popular beverages, posing a potential health risk. Published in the journal Science of the Total Environment, the research found that hot tea showed the highest levels of microparticles when compared to other drinks. This adds to growing global concerns about plastic pollution infiltrating our food and drink.

Microplastic Content in Beverages

Of 150 popular drinks analyzed, hot tea contained the most microplastics. A single liter could contain up to 60 microparticles, equating to roughly 12–15 particles per cup. For comparison, energy drinks contained 25 particles per liter, while carbonated soft drinks had 17. Furthermore, using paper takeaway cups increased the microplastic count to 22 particles per serving, compared to just 14 particles when using a glass mug.

Microplastics form from the breakdown of larger plastic items or are manufactured intentionally. Modern tea bags, often made from nylon or bioplastic, also release microparticles into the brew. Scientists note that microplastics are now ubiquitous, present in water, food, air, and even the human body. As researcher Mohamed Abdallah explained:

“Microplastics are tiny fragments that are either formed from the breakdown of larger plastic pieces or are manufactured intentionally for use in certain products.”

Expert Recommendations

To protect your health, experts recommend the following steps:

• Switch to loose-leaf tea.
• Choose only paper tea bags that are free from plastic components.
• Avoid takeaway cups with an internal plastic lining.

To minimize the impact of tannins, specialists advise drinking tea only between meals, pairing iron-rich foods with vitamin C, and limiting consumption to three cups per day.

This research underscores the critical need to understand the human health impacts of microplastics, as their presence in common beverages could have serious consequences. Amid rising consumer and environmental concerns, expert advice on choosing plastic-free tea options is increasingly relevant. The findings also highlight the necessity of reviewing manufacturing processes and packaging materials for beverages to reduce public health risks.
