Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain,” Grandjean says. “The effect of each toxicant may seem small, but the combined damage on a population scale can be serious, especially because the brain power of the next generation is crucial to all of us.”
As with other fresh water supplies (e.g., spring water, lake water, river water), bottled waters have low levels of fluoride. Fresh surface water contains an average of just 0.05 ppm. To put this in perspective, artificially fluoridated water (using industrial-grade fluoride chemicals) contains 0.7 to 1.2 ppm fluoride, which is 14 to 24 times more than the average natural level.
Fluoride Health Problems
There is a lot of controversy surrounding the presence of fluoride in public drinking water (fluoridation). For starters, before fluoride was used to fight cavities, it was (and still is) used in insecticides and rat poision.Fluorosis is a condition that wears down the enamal of the tooth, leaving behind white spots, making the teeth more vulnerable to cavities and decay. Fluorosis is a very real health condition that can effect both children and adults. More and more evidence is mounting against the use of fluoride, even in small amounts. But it doesn’t appear to be a critical issue according to the US Surgeon Generals, as the last 5 Surgeon Generals have supported the fluoridation of drinking water. Incidentally, the claimed health benefits almost always point to oral health. Fortunately, the CDC is calling for new labeling rules requiring manufacturers to list a product’s fluoride content, which we have found to be missing in some cases.
What is too much Fluoride?
Fluoride itself is actually required by our bodies in low doses. When consumed in high amounts, specifically the man-made fluoride that is in public drinking water, can cause problems.An estimated 5-10g of sodium fluoride can be lethal for some adults. While fluoride provides benefits to your oral health, it can also come with adverse side effects, that vary in severity depending upon the amount of fluoride consumed. Excessive consumption of fluoride can lead to gastrointestinal discomfort. This can occur with doses 15 to 20 times lower than actual lethal doses (0.2-0.3mg/kg). Fluoride in exessive amounts can also cause problems in the formation bone.
Here are some bottled water brands that contain little to no fluoride: http://www.naturalcuresplanet.com/?p=656
