In September 2003, and there go eight, an international petition signed by more than 300 scientists, chemists, technicians and environmentalists from 37 countries, requested a review, clarification and discussion about the benefits and harms of adding fluoride to the city water , ion used as a cavity preventative. Given the petition were presented several studies showing the risks to the overall health of the body, especially the bones, due to the ingestion of this potent chemical agent only when it exceeds 1 ppm is already causing problems to the teeth.
Since then, many studies have been proving links between fluoride intake and diseases of modernity. Autistic, for example, should not fluoridated drinking water. Although there is no confirmation of direct association between fluorine and dysfunction, it is known that it enhances the symptoms of autism.
The problem of adding a drug, poisonous or not, the water of all people, is a delicate matter. To what extent the authorities have the right to institutionalize a drug treatment in water for all citizens of all ages? Knowing the link between this product and triggering conditions, how and for what reasons remain the same guideline?
The withdrawal, given the evidence, hits the crossbar and economic policy. Byproduct of the aluminum industry, the ion, which kills an adult body with just five grams can not be simply thrown in nature.
The initial confidence in that tiny doses spread by water and food in the world, but would do well to teeth, preventing cavities, made that policies that consolidate gigantic contract world trade, now difficult to be undone, especially in developing countries have on one side the ignorant population that accepts the public and private decisions unquestioningly and other hubs of income, who defend the status quo at any cost.
Some countries, starting in 2003, before other, pulled fluoride from the water and began to add it to salt, since it uses less salt than water, which would reduce the risk of excessive intake of the ion, cumulative the human body. Confronted with evidence and to repair the mistaken view, based on research that only take into account the prevention of cavities, many countries simply do not use the more systemic use of fluoride as a caries preventive; bet on education, hygiene and topical applied directly to the teeth.
In Canada, Austria, Finland, Belgium, Norway, France and Cuba, some of the countries that fluoridate their water stopped, the decay rates continued to fall. Studies on the ingestion of fluoride, which since the 1970s has also been added to foods, milk powders and some medications, severe harm and cumulative point to overall health. Damage begin by fluorosis, which can be mild, causing white spots on teeth or severe, when the permanent teeth get brown spots or becomes lost, crumbling teeth. For this to occur enough that children aged zero to six years old are exposed to daily intake of the ion. The visible result only appears in the permanent teeth, since fluoride intake in pregnancy compromises the child's first teeth.
When ingested fluoride is rapidly absorbed in the stomach and small intestine. It is known that 50% of it is excreted by the kidneys and the other half is housed together with calcium tissue. Teeth and bones, over time, start to become deformed, and cracks arise diseases.
The major connective tissue mineralization of the bones, skin, arterial wall is affected tissues lose flexibility, become stiff and brittle. For all this to happen, according to 1977 study by the National Academy of Sciences, USA, the human body would need to absorb for 40 years only 2 mg of fluoride per day. It seems difficult to eat much, but fluorosis is already a fact, proven a modern disease.
Several studies show that fluoride chemical is so toxic as lead and, like this, cumulative. The older more we increase the concentration of fluoride in our bones, which brings greater risk of cracking and diseases like osteoporosis. The natural version of fluorine found in nature, including mineral waters, fish, vegetables and teas have 25% absorption by the human body, but the artificial fluoridation is almost completely absorbed.
Much is deposited in solid parts of the body, bone, and part goes to small teeth. It is believed that fluoride has a natural role to human health, but that has not been fully proven.
