> What figures can you point to on mg/L of fluoride in (commonly consumed) green tea vs tap water? Municipal tap water in the US is fluoridated between 0.7mg/L and 1.2mg/L, per the CDC's 1962 guidelines[1]. To my knowledge, most municipalities choose the lower end of that range (since the effects are diminishing and, well, it's cheaper). By contrast, at least one survey of black tea infusions finds an average of 2.65mg/L[2]. So over twice the CDC's highest baseline for municipal fluoridation. (Note: at that average for black tea, an adult would still need to drink ~4L of black tea a day to pass the CDC's tolerable upper limit. People grossly overestimate both how much fluoride is dangerous, and how much they actually consume.)
