you're not addressing the point about accumulation of fluoride over time.
you dont see brown stained teeth as an adverse effect, which is just nasty
you have no idea how long it takes the body to detoxify from fluoride, or how much fluoride is safe over a given time span. or if it varies according to the person.
you're not addressing the outrageous cost to the tapayer.
you're not addressing all the medical professionals and countries who oppose water fluoridation for the same reasons im stating.
you're not addressing the studies done by the CDC itself that suggest fluoride intake is not good for small children, pregnant women, and anyone under 8 years old.
you just keep saying the same narrow-minded shyt over and over again.
so until you address the above points with a level of intellectual honesty there's really no point in continuing this convo. you're gonna keep repeating the proper dosage argument, and im going to keep coming with the above argument. ive addressed your lone point about proper dosage by asking questions about accumulation over time--a response which you have yet to generate.
so let me ask you this... if the fluoride levels in our water supply are at "optimum" levels then why do so many people get fluorosis from water fluoridation? you're so sure we're at the optimum levels of fluoridation, but if we were at optimum levels wouldnt there be zero negative effects as you claim? but since there are negative effects, we must NOT be at the optimum range for water fluoridation, correct?
also, i did a couple minutes of research to find out how the body detoxifies from fluoride intake, this is what i found:
http://www.fluoridation.com/fluorideindrinkingwater.htm
"Fluoride accumulates in the body. Healthy adult kidneys excrete 50 to 60% of the fluoride ingested each day (Marier & Rose 1971). The remainder accumulates in the body, largely in calcifying tissues such as the bones and pineal gland (Luke 1997, 2001). Infants and children excrete less fluoride from their kidneys and take up to 80% of ingested fluoride into their bones (Ekstrand 1994). The fluoride concentration in bone steadily increases over a lifetime (NRC 2006)."
if these studies are legit then wave goodbye to your entire argument. just the last sentence alone from the National Research Council's 2006 report on water fluoridation kills your whole argument.
