Cheap teas contain too much fluoride.
Researchers from London have concluded that regular consumption of tea bags, especially it cheap varieties can lead to health problems.
According to doctors, this tea contains too much fluoride.
“The constant use of tea in cheap tea bags contribute to a critical increase in the level of fluoride in the body, which can cause significant damage to health”, – such conclusion was made by the authors of the study, researchers from the University of Derby.
Conducted by researchers at the calculations showed that the dose of fluoride found in tea bags, can exceed the regulatory established at 75-120%. A liter of tea prepared with the use of such bags will contain 6 mg of fluorine, whereas the daily rate for an adult is a maximum of 4 mg, said the scientists.
Experts recalled that an excess of fluoride in the body provokes the development of osteoporosis, muscle weakness, pain in the joints. There are studies whose results demonstrate that high levels of fluoride can lead to a reduction in the strength of the teeth and to the development of kidney disease and in some cases of Oncology, said doctors.
They explained that the cheapest types of packaged teas are dangerous because their production used old tea leaves, which accumulates the most fluoride. According to them, a characteristic symptom of the fact that the human body suffers from overabundance of fluoride is the appearance of black spots on the teeth.
