Studies indicated that certain tea marks (even those claimed to be organic or pesticide free!) contain pesticides known to be carcinogenic in quantities well in excess of the US and EU standards!
Before drying teas are typically not cleaned, and pesticide residues are left.
In a research published by Food Research International, cheaper tea blends reveal excessive fluoride content, and thus increase the risk of several diseases, including as kidnapping, bone tea and even cancer.
Research has demonstrated that the majority of traditional tea brands such as Teavana, Yogi, Lipton, Tea Forte, Allegro, Celestial Seasonings, Tazo, Tetley, Bigelow, Tea Republic, Twinings, Mighty Leaf and trader Joe have significant levels of harmful chemicals, including synthetic fluoride and pesticides.
These toxins have an elevated level, which is really unsafer, and their ingestion leads to many severe health impacts.
Some brands contain around 7 parts per million (ppm) while the fluoride level permitted is 4 ppm. The fluoride level can remain in your body for years and is highly worrisome.
If you ask how fluoride initially ended in tea, you should know that when tea is grown, it builds up. The older leaves are therefore wealthier in fluoride and generally come from inexpensive tea brands. In addition, smaller, higher fluoride leaves are used.
Research also has shown that the levels of decaffeinated tea are greater than those of caffeine.
However, you shouldn’t quit drinking tea. You should buy loose tea and boil your tea at all times, as the tea bags have lower-grade leaves, which means they are higher in fluoride.
Also, the lowest fluoride in white tea. In addition, you should use organic tea because it has been grown more sophisticatedly and presumably the soil is irrigated with cleaned water.
