Hidden plastics in tea bags mean that tea drinkers could be consuming billions of plastic micro particles every time they have ‘a cuppa’.
This is according to a recent study, which was done at Montreal’s McGill University by Laura Hernandez and colleagues.
It found that nylon teabags steeped at 95 degrees Celsius released microplastics. The study showed that one brew could contain up to 11.6bn particles of harmful microplastics. A further 3.1bn were nanoparticles which can potentially cause damage on a cellular level.
These levels are thousands of times higher than those reported previously in other foods and drinks.
The teabags made from nylon have potential to release this plastic into our bodies and subsequently the environment.
The health implications these products have not yet been fully studied and the study’s authors said more research is needed to determine the effect of these plastics on humans.
