    I drink tap water. I drink fluoridated tap water, and I gave it to my kids. I didn't have it as a child, and well water without fluoride got credit for some really soft teeth, per my dentist. I never believed any of this nonsense, BUT I'm really tired and this article kinda makes sense.

    Harvard Study Confirms Fluoride Reduces Children's IQ

    A recently-published Harvard University meta-analysis funded by the National Institutes of Health (NIH) has concluded that children who live in areas with highly fluoridated water have "significantly lower" IQ scores than those who live in low fluoride areas.
    In a 32-page report that can be downloaded free of charge from Environmental Health Perspectives, the researchers said:
    A recent report from the U.S. National Research Council (NRC 2006) concluded that adverse effects of high fluoride concentrations in drinking water may be of concern and that additional research is warranted. Fluoride may cause neurotoxicity in laboratory animals, including effects on learning and memory ...
    To summarize the available literature, we performed a systematic review and meta-analysis of published studies on increased fluoride exposure in drinking water and neurodevelopmental delays. We specifically targeted studies carried out in rural China that have not been widely disseminated, thus complementing the studies that have been included in previous reviews and risk assessment reports ...
    Findings from our meta-analyses of 27 studies published over 22 years suggest an inverse association between high fluoride exposure and children's intelligence ... The results suggest that fluoride may be a developmental neurotoxicant that affects brain development at exposures much below those that can cause toxicity in adults ...
    Serum-fluoride concentrations associated with high intakes from drinking-water may exceed 1 mg/L, or 50 Smol/L, thus more than 1000-times the levels of some other neurotoxicants that cause neurodevelopmental damage. Supporting the plausibility of our findings, rats exposed to 1 ppm (50 Smol/L) of water-fluoride for one year showed morphological alterations in the brain and increased levels of aluminum in brain tissue compared with controls ...
    In conclusion, our results support the possibility of adverse effects of fluoride exposures on children's neurodevelopment. Future research should formally evaluate dose-response relations based on individual-level measures of exposure over time, including more precise prenatal exposure assessment and more extensive standardized measures of neurobehavioral performance, in addition to improving assessment and control of potential confounders.
    Studies Have Repeatedly Linked Fluoride to Reduced IQ and Brain Damage
    There are so many scientific studies showing the direct, toxic effects of fluoride on your body, it's truly remarkable that it's NOT considered a scientific consensus by now. Despite the evidence against it, fluoride is still added to 70 percent of U.S. public drinking water supplies.
    It amazes me that the medical (and dental) communities are so stubbornly resistant to connect the dots when it comes to the skyrocketing increase of cognitive decline in adults and behavioral issues in children (ADD, ADHD, depression and learning disabilities of all kinds). In fact, there have been more than 23 human studies and 100 animal studies linking fluoride to brain damage. Fluoride can also increase manganese absorption, compounding problems, since manganese in drinking water has also been linked to lower IQ in children.
    Reported effects of fluoride on your brain include:
    • Reduction in nicotinic acetylcholine receptors
    • Damage to your hippocampus
    • Formation of beta-amyloid plaques (the classic brain abnormality in Alzheimer's disease)
    • Reduction in lipid content
    • Damage to purkinje cells
    • Exacerbation of lesions induced by iodine deficiency
    • Impaired antioxidant defense systems
    • Increased uptake of aluminum
    • Accumulation of fluoride in your pineal gland"

    So, people in cities drink fluoridated water, while rural folk drink well water. Now, lets look at voting patterns...

    you first should notice that this is a meta analysis study <which really means prior to this there were lots of studies where one said one thing and another said something else and someone is trying to make sense of the various conclusion which ALL seem to contradict one another.

    secondly notice that the words 'highly floridated water' <which suggest this is water that occurs naturally and is not the product of man made manipulation.

    imho... given the above two items it appears that at least some of the conclusion are manufactured to increase book sales and not to increase awareness of safety concern of folks drinking water.

    in places where there is high fluoridated water (I think the Rio Grande Valley is one of those kinds of places) almost everyone buys reverse osmosis water to drink and for the making of tea or coffee.

    I'm just really worried about the accumulation of fluoride in my pineal gland! :shock:
    (It sort of explains things though). :lol:

    A tec snip> " it appears that at least some of the conclusion are manufactured to increase book sales and not to increase awareness of safety concern"

    So often the case in much of the info we are exposed to. There should be a procedural check list we use when appraising any info; like who signs the authors pay check, is it to merely create a pull to the advertisement also splashed around, etc. Look at the authors other work and see if there is a pattern of sensationalist topics.

    fluoride vs iodine

    My personal experiences with taking fluoride tablets as a child are very bad: mottled, crumbly teeth were the result.

    The negative effects of fluoride are on many levels, one of them is the interference with our iodine levels:

    Make sure you get enough iodine and cut out fluoride wherever possible.

    It's disgusting when you can't accept an knowledgeable article, on a subject, at face value. This day and age of extremism and exploitation, all in the name of filling bank accounts, is driving me to distraction (or is that the desired out come).
    Thanks tecumseh, for pointing out the nuances.

    In west Texas, pregnant mothers drink bottled water or their babies first teeth will be brown from too much fluoride. I dunno. Have to go to work and the goat has diarrhea (new one on me)

    The article may show a need for further research, but retrospective studies are an easy arena to manipulate statistics to prove your point of view, which is how I interpret this study. No offense intended to those with other interpretations. The whole idea of fluoride in drinking water is a hot topic and there is truth on both sides of the debate. :)

    Flouridated tooth paste is still being sold, isn't It? Maybe it is a matter of what the areas flouride level in water is. Some areas of the country are low in iodine, some low in selenium; some areas are high enough to be borderline troublesome. Should one size fits all advice be taken with a grain of salt or without?
