Most conventional tea brands such as Lipton, Uncle Lee’s, Signal, King Cole, Tetley, and Twinings contain high levels of pesticides, and potentially fluoride. (1) We are not talking about calcium fluoride which is a natural element, but about the synthetic fluoride which is a toxic byproduct. Cheap teas are most likely to have higher levels of fluoride, thereby damaging your cells and overall health. (2)
Cheap Tea Contains Fluoride and Pesticides
Most teas are not washed before being dried, thus non-organic teas contain pesticide residues. Some tea brands (even those claimed organic or pesticide free) have been found to contain pesticides that are known carcinogens – in quantities above the US and EU limits!
A study published in the journal of, Food Research International, found that cheaper blends contain enough fluoride to put people under the risk of many illnesses such as skeletal fluorosis and fluorosis of the teeth (3)
In fact, some brands of cheap tea contain nearly 7 parts per million (ppm) and the allowed level of fluoride is 4 ppm. This is quite scary since fluoride gets into your bones and accumulates in your body. It stays there for years.
How Did Fluoride Get Into Tea?
The tea plant accumulates fluoride as it grows. This means that old leaves contain the most fluoride. Cheaper quality teas are often made from old leaves that contain more fluoride than young tea leaves. Additionally, these cheaper brands use smaller leaves which contain more fluoride.
And what about decaffeinated tea?
Well, decaffeinated tea showed higher fluoride levels than caffeinated tea.
So what is the solution? Should you stop drinking tea all together? Of course not!
- First of all, make sure to buy loose leaf tea and brew your tea from scratch. Bagged tea which might seem convenient and ready to go, is often made from low quality leaves which surely contain more fluoride.
- Stick to white tea. It has the least amount of fluoride. (2)
- Buy organic tea because the methods for cultivation are more sophisticated and conscious. They might even use purified water for the soil.
