A cup of black tea, which usually includes a little fluoride.
In fact, there is fluoride in tea, with green tea having the highest amounts of fluoride, as a general rule. The presence of fluoride in tea is caused by tea plants’ tendency to bioaccumulate, which means they absorb a wide variety of materials from the environment around them and then store those materials. In areas where there is a lot of fluoride pollution, tea plants accumulate fluoride, and when the leaves of these plants are fermented, they release the soluble fluoride inside. When tea is made with fluoridated water, obviously the amount of dissolved fluoride increases even more.
Green tea usually contains the highest amount of fluoride.
Several studies have been conducted on fluoride in tea, with most studies concluding that the amount of fluoride in tea is increasing, due to increased industrial pollution, which contaminates the air, water, and soil. The older the tea plant, the more fluoride it tends to accumulate, with younger, tenderer tea plants containing less fluorine, simply because they have had less time to accumulate it. In some cases, four cups of tea may contain one-third of the recommended daily fluoride intake before accounting for other fluoride sources such as water and dental care products.
Several studies have been carried out to assess fluoride levels in different teas.
Fluoride is a chemical that has been shown to be beneficial in preventing cavities. In the 20th century, several communities began to fluoridate their water and recommend the therapeutic use of fluoride to prevent cavities, and a general decline in tooth decay was observed in areas with consistent fluoridation, especially in people who take care of their teeth. Fluoride is also generated as a by-product in many industrial processes, which explains how it enters tea plants.
Excessive fluoride consumption can cause a condition known as fluorosis, which causes teeth and bones to become discolored and brittle. Some studies also suggest that high levels of fluoride consumption can also raise the risk of certain cancers, making fluoride in tea a concern for people who want to take care of their health, especially since teas like green tea are often recommended for women. cancer prevention.
The amount of fluoride in tea, for now, is only a big issue for people who drink a large volume of concentrated tea every day or for people who live in areas with heavily fluoridated water. Several cases of fluorosis have been linked to high tea consumption in Asia, where some of the water is naturally fluoridated due to the dissolved minerals it contains.
