Most conventional tea brands such as Lipton, Allegro, Celestial Seasonings, Tazo, Teavana, Bigelow, Republic of Tea, Twinings, Yogi, Tea Forte, Mighty Leaf, Trader Joe’s, Tetley contain very high levels of toxic substances such as fluoride and pesticides. We’re not talking about calcium fluoride which is a natural element, but rather hydrofluorosilicic Acid, a toxic industrial waste by-product. These levels are dangerously high to the point of being considered unsafe. So drinking cheap tea can be as bad as eating junk food.
