What’s in your Water? Part 3

What’s in your Water? Part 3…FLUORIDE.

Well, water week has become a bit more than a week, it’s more like two weeks. My apologies for the delay in sharing information with you.

What is fluoride? According to the EPA, fluoride is “salts that form when fluorine combines with minerals in soil or rocks.” Why is it being added to the public water supply? To promote dental health. Why would dental health need to be promoted? It’s not that the water we’re drinking is full of tooth-rotting properties. Hmm. It wouldn’t have to do with the large consumption of white sugar and processed food, would it? If fluoride is safe to ingest (which is what we do when we drink water), why is it not safe to swallow toothpaste?

What are some potential health hazards of fluoride above “acceptable levels”?
– increased likelihood of bone fractures in adults (osteoporosis anyone?)
– “an increased chance of developing pit in the tooth enamel, along with cosmetic effects to teeth.”
– What can pits in tooth enamel lead to? Oh, that’s right, dental carries!
– What can untreated dental carries lead to? Cavities!
– neurotoxicity and reduced IQ in both adults and children
– certain types of cancer
– increase in autoimmune disorders

If the EPA currently views 4.0 mg/L as an acceptable level of fluoride, with a secondary, non-enforced level of 2.0 mg/L, why is it then that according to Choi, et al (2012), “the US Department of Health and Human Services (DHHS) and the US EPA recently announced that DHHS is proposing to change the recommended level of fluoride in drinking water to 0.7 mg/L from the currently recommended range of 0.7 – 1.2 mg/L, and the US EPA is reviewing the maximum amount of fluoride allowed in drinking water, which is currently set at 4.0 mg/L”? Why haven’t the levels been reduced, 2 years after the paper’s publication? Let’s think on that…
