Recently I learned that black and green tea contains not-insignificant levels of fluoride, because the tea plant concentrates the substance in its leaves as it grows. This suddenly made amazing sense: Englishmen comprise an empire pacified by means of voluntarily drinking tea (as well as China/Japan, et. al.) and in fact making it a veritably religious ritual that is so ubiquitous that you name mealtimes after it. So when other nations pondered how to introduce fluoride to non-tea-drinkers, they needed to be crafty about it. Thanks mom, for dozens of gallons of wholly ineffective fluoridated water when we were growing up. Surely my perpetual stupidity and mental illness and Prozac prescriptions are unrelated.
