Fluoride is the most bone seeking element known to mankind. The US Public Health Service has stated that fluoride makes the bones more brittle and dental enamel more porous. Fluorides lower the intelligence capacity of humans, with children, again, especially susceptible to early fluoride toxicity. IQ levels were significantly lower than children not exposed to fluorides in all age groups listed. Further studies proving the neurotoxicity of fluoride in rats have also been conducted by Dr. Phyllis Mullinex and her co-workers.
Studies proving that fluorides transfer through the placenta are well known.
There are also several studies linking aluminum with fluoride, showing that the bioavailability of aluminum is increased in the presence of fluorides, causing aluminum in the brain to double in treated animals. Environmental fluoride is implicated in this. The US Public Health Service estimates that 1 in 5 children have dental fluorosis. Studies have been conducted directly linking bone tissue damage to children with dental fluorosis. Fluorosis is the first visible sign that destructive effects of fluoride are also occurring in bone, connective tissue, immune and enzyme functions.
