A topic I rarely speak on, but have known about for many years-plastic in your teabags and the cause for concern. 😡🤨
“It all started with a 2019 Canadian study at McGill University (1) published in the Environmental Science & Technology Journal, which stated that steeping a plastic tea bag at a brewing temperature of 95°C releases around 11.6 billion microplastics and 3.1 billion nanoplastics into a single cup. Microplastics are tiny pieces of plastic between 100 nanometres and 5 millimeters in size. Compared to salt, for example, which has been also found to contain plastic, each cup contains thousands of times the greater mass of plastic, at 16 micrograms per cup.”
“Another study published in March 2023 in the International Journey of Surgery (3) cites a wide variety of health conditions, including endocrine disruption, reproductive toxicity, cancer risk, problems with metabolism and nutrition, and interference with neurodevelopment, as concerns related to microplastic exposure, particularly to those heated during processing, like tea bags used in million cups of tea over a lifetime.”
One should always consider using looseleaf tea as much as possible. However, that is not always a viable option.
This is a great article on why you should choose plastic free teabags and which bags are free of ick.
