Recent research on causes of heart disease has revealed a link between fluoride and coronary artery disease. The study, referred to as: Association of Vascular Fluoride Uptake with Vascular Calcification and Coronary Artery Disease.
Researchers examined the arteries of 61 people for signs of calcification – artery hardening due to calcium, and fluoride absorption.
Connection between fluoride and heart disease was described as “significant”.
Fluoride was detected in the vascular walls (veins) of 96% of study participants, and calcification was observed in the vascular walls of 88% of participants. Study participants arteries also showed significant calcification and fluoride absorption.
Doctors who reviewed study participants’ medical histories noted that there was a very strong link between the presence of fluoride in artery walls and the history of heart disease. Researchers concluded that: ”An increased fluoride uptake in coronary arteries may be associated with an increased cardiovascular risk.”
Too much fluoride in public water supplies:
Earlier this year, the US Department of Health and Human Services (HHS) and the Environmental Protection Agency (EPA) jointly announced that they would be recommending that fluoride levels in drinking water be lowered because of a slow rise in fluorosis – fluoride poisoning that causes brittle bones, brain damage, and discolored teeth, among other health problems.
The HHS proposed lowering maximum allowable levels of fluoride in water to 0.7 mg/l. The EPA, which actually sets the standard, currently allows up to 4 mg/l of fluoride in water. This means that the EPA allows 5.71 times more fluoride in water supplies than the HHS actually deems safe! The EPA has said it is considering lowering the allowable level of fluoride in water, but has not officially acted yet.
Why the difference?
The EPA and the HHS have two separate goals when it comes to fluoride:
HHS – (recommendation) Reduce tooth decay while minimizing the rate of fluorosis
EPA – (Sets the standard) Maximum concentration of fluoride it considers safe
What this means: The EPA now believes its current standard (4 mg/l) is too high, but the EPA is not ready to set a new standard yet. Until the EPA sets a new standard, it is possible that the level of fluoride in your water could pose risks to your health.
In Ireland, the Expert Body on Fluoridation recomended in 2002 that the level of hydrofluorosilicic acid be reduced from 1ppm to 0,7 ppm to reduce the incidence of fluorosis and other possible side effects of this chemical. Four years later the Dept. of Health had still not implemented the reduction. It is impossible to tell at what level we are being fluoridated/medicated at present as the EPA website which used to list the results of the fluoride additive testing was taken down in 2001 , at the height of the Celtic Tiger.
