Following a spirited discussion with Furor Teutonicus in the comments, while this week looks quiet workwise I thought I’d do some following up on said discussion regarding Fluoride and other environmental factors.
There’s also a meme out in the wilds of medialand, unsubstantiated by actual medical evidence, that in order to ‘stay healthy’ people should drink ‘eight glasses of water’ per day. Eight fluid ounces in each. Sixty four fluid ounces. Three and a bit pints. Influenced by this garbage, everywhere you go there are people in shops, offices, on the streets with their dinky little bottles of Peckham Spring which may well be sourced from the Public Water Supply.
As for what’s in that water, watch the video of what Dr David Kennedy has to say about Fluoride in the public water supply. Especially about not being able to get rid of fluoride salts with boiling, activated carbon filtration, ‘cold filtering’ or even ‘reverse osmosis’ (Unless it’s the high pressure variety, which is expensive). ‘Pure’? I should cocoa (Derisive snort).
As for my little ‘Peckham Spring’ jibe, well me darlings, you’d be amazed at how many companies source their supposedly ‘pure’ water straight from the same sources as the public supply. Not all of them, but not a tenth, or an eighth, but over a quarter of all that bottled water on the grocery and supermarket shelves, possibly more, is likely exactly the same as what comes out of your tap. And that’s even before doing the individual testing and number crunching on how much and what contains fluoride salts. There’s just no readily collectable evidence. But you can bet your boots that the companies making a fat buck off it aren’t telling. Never mind the allegations of how much bacterial contamination there is in the supposedly ‘pure’ bottled stuff. Even if your bottled water has ‘0% fat’ on the label. I mean, ‘low fat’ water? Who knew?
Now to the meat of the topic, which is what is actually in your water supply, and what, if any deleterious effects it might have. Or even the long term effects of sub-toxic dosage and the risks of removing those dosages.
According to this animal based study, there is no detectable cancer risk associated with prolonged low level exposure to fluoride salts, although some osteosclerosis was observed. Well, you might ask, what about the documented neurological effects? It’s true that in acute cases of fluoride poisoning, headache, tremors, muscle spasm, tetanic contractions, hyperactive reflexes, seizures, and muscle weakness can result. Acute toxicity levels are 5mg per kg of body weight, so for a seventy five kilo human you’d have to swallow over 375mg in one sitting to get very sick indeed, very quickly. There’s also a high probability that kind of dose would be fatal. Women, because the average UK female bodyweight is a tad over 70kg, would be most susceptible. For those under 60kg, the acute toxicity level kicks in much earlier. Especially if the immune system is depressed or simply busy with other matters.
Now if you’re one of these people sipping two litres of water a day under the delusion that this is ‘healthy’, up until May 2015 in fluoride using areas of the USA, you might be ingesting as much as 5mg of fluoride salts a day from water alone, or in the case of a 60kg woman, a sixtieth of an acute dosage. That’s without the fluoride salts in toothpaste and bathing water. More if dietary supplements like multivitamins are being regularly taken. For the sake of a hypothetical argument, let’s round up that daily dosage (with dietary supplements) to 8mg, which is only 2mg below the maximum permissible 10mg per day overall dose. So, not quite enough to bring on acute symptoms, but as any fule kno, small doses over long periods of time can result in significant ill effects. Mostly they fly below the radar, not flagging up any immediate concerns, but can exhibit long term consequences.
For most of us this isn’t a problem; we don’t chug anything like eight glasses a day. Nor should we. Too much flushing of the system raises another Cerberus head. Constantly flushing the salt out of ones body can lead to things like mild hyponatraemia (Low blood salt). Which carries yet another set of health risks. We need sodium. If our bodies didn’t need a specific amount of salt, we wouldn’t have developed kidneys. No matter that some people want to eliminate dietary salt altogether, which is not only stupid, it’s secure ward barking.
What has been suggested is, rather like repeatedly getting shitfaced while pregnant leads to foetal alcohol syndrome, excess ingestion of fluoridated water while pregnant may be associated with the uptick in cases of Autism and Attention Deficit Disorders in children. As yet, there are few reputable studies to indicate whether this is true or not. Other suggested causes of Autism have indicted certain household cleaning agents or low level infections during pregnancy and a whole heap of other potential agents.
What is proven is that low level doses of fluoride in the water supply are beneficial as far as teeth are concerned and getting rid of fluoridated water altogether is like refusing vaccination, cutting off your nose to spite your face. However, in light of emerging evidence, reducing the fluoride dosage from 1.5mg / litre to 0.7mg, (15 down to 7 parts per million) because of the toxic nature of fluoride salts, can be seen as a good move. Although your dentist might not be convinced. But then, it took a while to find out that your shiny silver looking mercury amalgam fillings could be poisonous.
