1. Plastic Tea Bags and Microplastics
While traditional tea bags were made from paper, many modern brands have shifted to plastic-based materials like nylon and polyethylene terephthalate (PET). When steeped in hot water, these plastic tea bags can release billions of microplastic particles into your beverage. A study published in Environmental Science & Technology found that a single plastic tea bag can release approximately 11.6 billion microplastics and 3.1 billion nanoplastics into a cup of tea (ACS Publications).
These microplastics are not just an environmental concern; they can also pose health risks. Research indicates that microplastics can be ingested and accumulate in the human body, potentially leading to inflammation and other health issues .
2. Additives and Contaminants
Beyond the tea bag materials, the tea leaves themselves can be problematic. Many teas contain “natural flavors,” a term that can mask a variety of undisclosed additives. Additionally, non-organic teas may be contaminated with pesticides, herbicides, and heavy metals. For instance, tests have revealed that some teas contain residues of pesticides and other harmful substances (MAMAVATION).
✅ What to Look for in Safer Tea Options
To ensure a healthier tea experience, consider the following:
- Tea Bag Materials: Opt for tea bags made from plant-based mesh, unbleached paper, organic cotton, or hemp. These materials are biodegradable and free from harmful plastics.
- Organic Certification: Choose teas that are certified organic to reduce exposure to pesticides and other chemicals.
- Third-Party Testing: Brands that invest in independent, third-party testing for heavy metals, pesticides, and other contaminants show a commitment to transparency and safety. This is especially important for herbal teas, which can absorb toxins from the soil.
- Transparent Labeling: Select brands that disclose all ingredients and avoid vague terms like “natural flavors.”
🚫 Brands to Be Cautious Of
According to the Center for Environmental Health, several popular tea brands have been found to use plastic in their tea bags, including:
- Tazo
- Teavana (Starbucks)
- Celestial Seasonings
- Mighty Leaf Teas (owned by Peet’s)
- Tetley
- Twinings
- Lipton
These brands may contribute to microplastic exposure when their tea bags are steeped in hot water. With that being said, some of the companies are actively working on reducing plastic in their tea bags, so check the websites of these brands for most up to date materials used.
