Black tea is in high demand among the consumer, but using it in large quantities can significantly affect people’s health.
Some varieties of black tea contain especially dangerous fluorine, which is a destructive substance. Its presence in tea is not justified by anything, and the consequences can be catastrophic. Any diseases of the bones, as well as their weakening, can be caused precisely by the excessive consumption of black tea.
By itself, this drink can at least affect the teeth, at most destroy the bones or significantly weaken them. This may not be felt in youth, but in older age exposure to fluoride in black tea can be dangerous.
