SOME CONFOUNDING VARIABLES IN CONTROLLED TRIALS

(Not Comprehensive)

1.)  Many householders in fluoridated areas have made other arrangements for clean fluoride free drinking water, and therefore need to be excluded from fluoridation trials:  

(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 aggravated by 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. – If we must use animals for experiments, guinea pigs are therefor a better choice, and will provide more accurate results. See below 

3.)  Residents moving between fluoridated and non-fluoridated areas before and during trials need to be identified and excluded.
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 teeth formation.) Fluoride delays the eruption of teeth in humans and animals creating more statistical confusion.

4.)  Workers moving between fluoridated and non-fluoridated areas on workdays also 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 will interfere with results. This will mostly be soft drinks, beer, bottled water, – some imported from overseas, and wine. (Grapes are often sprayed with cryolite, a fluoride containing agricultural spray.)

See →  Food Standards Aust. & NZ

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’ rather a scientific nonsense.

7.)  The 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 or non-use periods  (night time) have high/er readings of fluoride.

9.)  Different dietary habits and nutrient status of residents: Body weight, infant formulae mixed with fluoridated water, rather than breast milk for babies, are yet more complications. Fluoride-pregnant women!

10.)  Climate, weather, geographic latitude and elevation cause personal 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 (Queensland) because of their high water and tea consumption due to the risk of ‘Fluoride storage disease’ (Tea is high in F.).

In Australian underground mines: There have been a number of studies that the NHMRC and FSANZ are desperate to avoid. “The average fluid consumption per shift was 6.48 litres (over this mix of different shift lengths) with a standard deviation of 2.41 liters and range of 2.40 to 12.50 litres”. 

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 ‘Hidden Dangers 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 in a fluoride environment. Fluorides are corrosive.

16.)  Fluoride pollution from power stations, industry and 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,  aluminum 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. ( Industrial chimneys should have scrubbers.)

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.

GENOTOXICITY & IMPAIRED MELATONIN SECRETION

19.)  Other sources of fluorides: Tea, teflon, industrial pollution, toothpaste, dental treatments, agricultural  chemicals, fluorinated pharmaceuticals.    More   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 factors listed above. Fluorides are extremely reactive, variables dangerous and in many ways a little unpredictable and underreported.    More sources of fluoride exposure:

PFOS, PFOA, PFNA, PFAS, PTFOS, PFOA, PFHxA and PFBS etc. (All the ‘Fs’. are for fluoride.) Contaminants only 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.)  Fluorides are absorbed through the skin when washing and showering.

22.)   Letter – Philip Heggen-Safe Drinking Water Act

       ♦  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 unlike most mammals, 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.

As can be seen by the list of 22 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.

     All the ‘Fs’ Are Code for Fluoride. –  Fluoride is a “Protected Pollutant”
and it will only appear in the mainstream media when it is being promoted.

As can be extrapolated from the above, in most situations
the harm done by fluoridation is probably greater
than current research would suggest.
