Plastic tea bags release about 11.6 billion microplastic particles into each cup when brewed. These tiny plastic fragments enter your body when you drink the tea, and scientists still don't fully understand their long-term health effects. If you drink tea regularly, switching to paper or loose leaf options could help you avoid this exposure.
Researchers at McGill University conducted a study examining the release of microplastics from plastic tea bags during brewing. The study, published in Environmental Science & Technology, found alarming results.
When a single plastic tea bag is steeped in hot water at 95°C (203°F), a typical brewing temperature, it releases approximately 11.6 billion microplastic particles and 3.1 billion nanoplastic particles into the beverage.
The particles released were in the microgram range and were identified as nylon and polyethylene terephthalate (PET), the same materials the bags are made from.
While the health impact of ingesting these particles is still being studied, the findings raise significant concerns. Prior research has linked microplastic ingestion to inflammation, oxidative stress, and potential endocrine disruption.
- Switch to loose-leaf tea with a stainless steel or ceramic infuser
- Use paper tea bags, which release significantly fewer particles
- Avoid squeezing plastic tea bags, which may release more particles
Brands commonly using plastic mesh tea bags include Twinings, Tetley, and Lipton for their pyramid-style bags. Always check the packaging to see what the bag is made of.
What you can doAI-generated
- ✓Check whether your tea bags are made from plastic mesh or nylon by looking at the package label — plastic pyramid-style bags from brands like Twinings, Tetley, and Lipton release billions of microplastic particles when brewed.
- ✓Switch to loose-leaf tea paired with a stainless steel or ceramic infuser to eliminate microplastic exposure from tea bag materials entirely.
- ✓Choose paper tea bags instead, which release significantly fewer microplastic particles than their plastic mesh counterparts.
- ✓Avoid squeezing or pressing down on plastic tea bags while they steep, as this action may release additional microplastic particles into your drink.
Always consult a healthcare professional for personal medical advice.
