Tea is a daily ritual for many people - at breakfast, during work or for relaxation. It is traditionally considered a healthy drink that calms the nervous system, improves digestion and helps to focus. At the same time, new scientific evidence suggests that even the usual cup of hot tea may have hidden health risks.
A study by scientists has shown that hot tea contains the highest amount of microplastics among popular beverages. On average, one liter of the drink can contain up to several dozen microparticles, which is significantly higher than other soft drinks. The high temperature of boiling water contributes to a more active release of these particles into the liquid.
A separate danger is the way tea is served. The use of take-out paper cups, which have a plastic inner coating, leads to even more microplastics getting into the drink. In such conditions, the number of particles increases compared to tea brewed in glass or ceramic vessels.
Scientists explain that microplastics are tiny fragments that are formed during the breakdown of plastic materials or are intentionally used in production. Today, these particles are found almost everywhere - in water, food, air and even in the tissues of the human body.
Although the impact of microplastics on human health is still being actively researched, animal experiments have already linked them to the development of inflammatory processes, hormonal disorders and problems with the digestive system. One of the main sources of microplastics in tea is considered to be modern tea bags made of nylon or bioplastic, which actively release microparticles when exposed to boiling water.
In addition, experts draw attention to the content of tannins in tea - substances that give the drink astringency. They can reduce the absorption of iron from plant foods, which is especially important for vegetarians, pregnant women and people at risk of anemia.
To reduce potential risks, experts advise choosing loose-leaf tea, choosing bags without plastic components, avoiding take-out cups, and drinking tea between meals. It is also recommended to combine iron-rich foods with vitamin C and not exceed moderate consumption of the drink.
Despite the identified risk factors, tea remains safe for most people if consumed consciously and in reasonable amounts.
