While a warm cup of tea is often seen as soothing, it may be hiding a secret threat: nanoplastics that infiltrate deep into our bodies.
the prevalence of microplastics in our environment
Microplastics and nanoplastics have become ubiquitous in our surroundings. Over time, scientists have determined that inhalation and ingestion are the primary routes of human exposure. Food packaging is a major source of contamination by these plastics. However, an often-overlooked source is tea bags, which can release these particles into our drinks.
tea bags releasing billions of plastic particles
Certain manufacturers prefer using nylon or other plastic materials for tea bags instead of paper, claiming enhanced aroma diffusion. Yet, alongside the flavors, millions or even billions of microplastics and nanoplastics are released into boiling water. Researchers have confirmed that commercial polymer-based tea bags release millions of these particles when steeped.
- Nylon releases 8.18 million particles per milliliter.
- Polypropylene releases about 1.2 billion particles per milliliter.
- Cellulose releases approximately 135 million particles per milliliter.
from teabag to bloodstream
The alarming aspect is the ability of these plastics to be absorbed by intestinal cells and then circulate throughout the body. For the first time, researchers dyed micro and nanoplastics and exposed them to human intestinal cells to study their interactions. Their findings revealed that mucus-producing intestinal cells play a critical role in absorbing these pollutants.
impacts on human health
This discovery emphasizes the need for continued research on chronic exposure’s effects on human health due to plastic pollution. As the use of plastic in food packaging continues to rise, tackling microplastic contamination is crucial for ensuring food safety and protecting public health.
