Tea: harm or benefit?

Although fluoride and its derivatives are widely used in dentistry to prevent caries and strengthen tooth enamel, an excess of this microelement is not at all beneficial to health. According to the World Health Organization when taking more than 7 mg. fluoride per day there is an increased risk of skeletal fluorosis, as well as the risk of other acute diseases.

For this reason, if consumed more than 4 cups of low-quality tea bags, a person receives the maximum daily dose of fluoride and is at high risk of disease.

Meanwhile, the British tea company Newby Teas, together with researchers from the EUROFINS laboratory in London, found that some brands of packaged teas contain too much fluoride. So, several of the tested samples contained 1.25 mg of fluoride per 200 ml of brewed tea.

In addition to tea, fluorides are also found in other everyday foods: cereals, vegetables, milk, fruits, etc., which, in combination with poor-quality tea, significantly increases the risk of oversaturation of the body with fluorides.

The fluoride content is influenced not only by the quality of not only the tea leaf (the older the age of the tea leaf, the more fluoride it contains), but also the material from which the bag is made: artificial packaging materials and glue also contain fluorine compounds.

Tea: harm or benefit?

Newby experts recommend that all lovers of the ancient drink do not save on packaged teas and choose only high-quality brands. Their products undergo multi-stage quality control from the moment of gathering on the world’s best plantations to reaching the final consumer.

It is worth noting that among all the studied samples of famous brands, the smallest amount of fluoride is contained in the teas of the British company Newby Teas. For example, one cup of classic tea (200 ml) accounts for:

  • Newby Upper Assam in the Pyramids: 0.25 mg;
  • Newby English Breakfast in Pyramids: 0.31 mg;
  • Newby Assam packaged: 0.32 mg;
  • Newby English Breakfast packaged: 0.35 mg.
