The inability to control individual doses
renders the notion of an “optimum concentration”
and “dose” an impossible target and therefore a scientific nonsense.
SOME CONFOUNDING VARIABLES
( Not Comprehensive )
Submitted by one of our readers.
1.) Many householders in fluoridated areas have made other arrangements for clean fluoride free drinking water, and need to be excluded from research projects.
(From ABS 2013 data, 9.9% of Aussies use rainwater harvesting and 6.5% use bottled water as their main source of drinking water. But 32.4% of Aussies have water filters, and about one quarter of these may be fluoride filters – ‘Reverse Osmosis’.)
2.) Rodents are much used as laboratory animals, they manufacture Vitamin C, which means they need larger doses of fluoride to damage or kill them. Unlike us humans who must obtain Vitamin ‘C’ from our diets. (Most humans are deficient in ‘C’ which is made worst with fluoride exposure.) Guinea pigs are therefor better for biomedical research. They may be more expensive to keep, but like us humans they cannot produce Vitamin ‘C’ and need it supplied in their diet). See below ♦
If we must use animals for experiments, guinea pigs are a better choice.
3.) Residents moving between fluoridated and non-fluoridated areas before trials need to be identified and excluded from trials.
Fluoride damage for some people can take time, often many years. However some humans are very sensitive and will react to fluoridation in days. (Fluorosis of teeth will only be visible if fluorides are present at the time of tooth formation. – The pain from skeletal fluorosis is indistingishable from arthritis. )
4.) Workers moving between fluoridated and non-fluoridated areas on workdays need to be identified and excluded. – Some may take flasks to work; others may buy drinks at work.
5.) Food and drink, commercial and domestic, moving between fluoridated and non-fluoridated areas, and or imported from overseas, will interfere with results. This will mostly be soft drinks, beer, bottled water and wine. (Grapes are often sprayed with fluoride containing agricultural sprays, cryolite.)

6.) Unequal distribution of fluoridated water throughout city water mains. – Water engineers have raised this issue from the first proposal to add fluoride to drinking water. The inability to control individual doses renders the notion of an ‘optimum concentration‘ and “dose” an impossible target and therefore a scientific nonsense.
7.) Unrecognized difference between natural and artificial fluorides. Calcium fluoride occurs naturally, it is a problem as evidenced in many parts of the world, but the calcium acts as a buffer and renders it less injurious – but not harmless.
8.) People living at the end of a dead end streets: No explanation seems to exist, but readings especially after low flow or non-use periods (night time) have high/er readings of fluoride in the water mains.
9.) Different dietary habits and nutrient status of residents: Variation in body weight, infant formulae mixed with fluoridated water, rather than breast milk for babies, are more complications. Fluoride-pregnant women!
10.) Climate, weather, geographic latitude and elevation will cause large water consumption variations.
11.) Heavy manual labour resulting in higher water consumption, can be yet another variation. The NHMRC in 1954 was deeply concerned over sugar cane cutters (in Queensland) because of their high water and tea consumption due to the risk of fluoride overdose. – Tea is high in fluoride.
In Australian mines (coal and minerals) – there have been a number of studies that the present NHMRC and FSANZ are desperate to avoid. “The average fluid consumption per shift was 6.48 liters (over this mix of different shift lengths) with a standard deviation of 2.41 liters and range of 2.40 to 12.50 liters.” – (That is a lot of fluoride even if the tea is made with distilled water.)
12.) Genetic background – e.g. Negro and Australian aborigines are more sensitive to fluorides, (low kidney function). More → HERE
13.) Contaminants in the fluoride chemicals see separate list below…
14.) Pets need clean water too! Dogs receive extra fluoride doses in some flea treatments: ‘FRONTLINE’ contains Fipronil ⇔ Fluoride Dangers: What’s In Your Dog’s Water?
15.) Variations of water pipes: New or old, lead, concrete, cast iron, polythene, copper, stainless steel, and mixed lines. New concrete lined pipes absorb fluorides for some time. Lead pipes and solder joints will release lead into the water in a fluoride environment. Fluorides are corrosive.
16.) Fluoride pollution from power stations, industry, vehicles and occasionally volcanoes:
Air: fluoride releases from industry, Anthropogenic sources of atmospheric fluoride can result from coal combustion by electrical utilities and other industries.
Releases can also occur from refineries and metal ore smelters, aluminium production plants, phosphate fertilizer plants, chemical production facilities, steel mills, magnesium plants, and brick and structural clay manufacturers, as well as copper and nickel producers, phosphate ore processors, glass manufacturers, and ceramic manufacturers.
17.) Living near the ocean has the advantage of providing some iodine from the sea air which will help overcome the reduced iodine effect that fluoridation creates.
18.) See → FLUORIDE- & ELECTROMAGNETIC RADIATION-INDUCED
GENOTOXICITY & IMPAIRED MELATONIN SECRETION
19.) Other sources of fluorides: Tea, teflon, industrial pollution, toothpaste, dental treatments, agricultural chemicals, fluorinated pharmaceuticals. → More ← underreported.
PFOS, PFOA, PFNA, PFAS, PTFOS, PFOA, PFHxA and PFBS etc. are all fluoride contaminants.
(All the ‘Fs’ Are Code for Fluoride.) recently being acknowledged.
20.) Problems with fluorides for animals, people and plants are so many and varied that most of them go undiagnosed, and are often not mentioned in surveys, and many of the sources of fluorides are not recognised. – If you do not look, you will not find.
21.) As evidenced above, so many factors make scientific assessments of the benefits or otherwise of fluoridation impossible to tabulate. – Fluoride is a “Protected Pollutant” and it will mostly appear in the mainstream media only when being promoted.

As can be seen by the list of variables above, research into fluoridation, in the
field, the library, the laboratory or via statistics, requires much knowledge.
Many previous research outcomes have been compromised by
poor designs which have ignored some of the above.
Fluorides are extremely reactive variables,
dangerous and in many ways are
a little unpredictable.
♦ U.S. and Canadian studies found 25-33% of people are marginally deficient of vitamin C. Up to 20% of some populations are severely deficient.
College students, smokers, and older adults may be at higher risk of this deficiency.
More disturbing, humans have lost their ability to produce their own vitamin C.
According to Dr. Ronald Hunninghake (a world renowned vitamin C expert), every creature, when needed, can greatly increase production of vitamin C from their liver or kidneys except for humans, primates, and guinea pigs.
Dr. Hunninghake points out how we still have the gene that makes the
L-gulonolactone oxidase enzyme that converts glucose to vitamin C,
but the gene is non-functional.
