Tea bags may promote cancer cell growth.
Nutritionist Natalia Fariseeva warned about this.
The expert's statement is cited by NEWS.ru.

What is the danger of tea bags?
As Fariseeva explained, when making tea bags, they often use flavorings obtained by chemical methods.
They contain substances that provoke changes in metabolism and the growth of cancer cells.
Harmful substances, the nutritionist noted, accumulate in the body gradually.
And they don’t immediately make themselves known, destroying the body from the inside, ” the expert said.
In addition, unscrupulous manufacturers may use production waste – tea dust.
Expired tea is often put into tea bags, Fariseeva noted.
The older the tea leaf, the expert continued, the more fluoride it contains.
These substances provoke the growth of bone tissue and cause various diseases of the skeletal system.
Expired tea also contains aflatoxins, which cause irreversible liver damage.
