The researchers argue that with prolonged exposure to the body of large concentrations of fluoride, serious damage can occur, as reported by the Internet publication for girls and women from 14 to 35 years old Pannochka. net A team of specialists from Spain in the course of the study found that excessive consumption of strong black tea in large amounts can lead to problems with bone tissue, write foreign media.

In the course of the study, samples of various black tea varieties were analyzed relative to their effect on the condition of the internal organs and tissues of the human body.

Physicians managed to establish that in the vast majority of varieties of black tea contains a huge amount of a chemical compound, like fluorine. It is the influence of fluorine that leads first to fragility and brittleness of bone tissue, and then, with further use of tea, to the destruction of bones. The researchers argue that with prolonged exposure to the body of large concentrations of fluoride, serious damage to bone tissue can occur.

It is for this reason, for example, that dentists strongly do not recommend a toothpaste with fluoride content for a long time to clean teeth, since teeth can not be strengthened, but, on the contrary, can deteriorate.

The specialists also established that there is a certain risk group for the negative effect of fluoride on the body. This group of risk includes young children, young boys and girls of adolescence, as well as representatives of the weaker sex. The optimal amount is a dose of fluorine from two to three mg.
