BARWON FREEDOM from FLUORIDATION: consumer and professional action group in the Geelong region, acting to END the unfair, undemocratic and unsafe practice of water fluoridation
Effect of Dietary Fluoride on Food Intake and Plasma Fluoride Concentration
The effect of excessive amounts (200-600 ppm) of dietary fluoride on the food intake and plasma fluoride concentration of rats of various ages was investigated. In older animals, the decline in food intake was partially corrected within a week even though the plasma fluoride concentration remained elevated.
When the same amounts of fluoride were fed to younger animals, a longer exposure to the diet was required before an improvement in food intake was seen. The ability of the rat to increase its consumption of the high fluoride diet following an initial drop in consumption suggests some type of adaptation to the elevated plasma and soft tissue fluoride concentrations.
The effects of ingestion of excessive amounts of dietary fluoride by animals have been extensively studied and reviewed, and one of the major physiological responses repeatedly noted is a decline in growth rate.
This decline is the result of a marked decrease in food consumption by the animals, and some studies have specifically indicated that the degree to which the consumption is decreased is lessened as the period of exposure is extended. It has been shown also that the ingestion of a high fluoride diet by the rat results in an increase in plasma fluoride content, and that the decline in food consumption, at least in short-term experiments, is inversely correlated with this increased plasma fluoride.
This study was designed to investigate the response of food intake to dietary fluoride in more detail, and to further study the relationship between dietary fluoride, plasma fluoride, and food intake.

The Age report included an astonishing claim by an EPA director that while the fluoride is harmful to animals "the levels were safe for humans." In fact there appears to be no evidence for it being safe. It is parallel to the situation around Geelong where an Alcoa smelter and Shell oil refinery pump fluoride pollution into the air, and residents breathe it and eat it if they are home growing vegies and fruit trees. The risk is magnified if residents are consuming fluoridated tap water since it is the 'total intake from all sources' that causes fluoride poisoning or long term damage.
Maureen Minchin, Geelong resident, international consultant in infant feeding and lactation, and author of classic text "Breastfeeding Matters" has issued a renewed warning of the danger that fluoridated tap water poses for infants (August 2008).
Kangaroos crippled by fluoride at Portland and northern Melbourne suburbs. The Melbourne Age reported (21/2) a dramatic study showing that kangaroos living around several fluoride emitting industries are "pain-ridden" and suffering fluorosis, with "excessive bone growths, or lesions, on joints in the paws, ankles and calves."

Okay, okay ... so this might not be an 'official' health department warning, YET! But it is certainly the warning that should be issued by NSW Health, along with Dr John Carnie at the Victorian DHS and embattled Health Minister Daniel Andrews.
The above picture with the brown stains is 'moderate Dental Fluorosis', the tooth disorder caused by using fluoridated drinking water in childhood plus possible other sources of fluoride in the environment or diet.
REMEMBER - dental fluorosis is the tip of the iceberg, a biomarker indicating systemic fluoride poisoning on Dental Fluorosis at the FAN website.
Fluoridated water may damage the health of people with kidney disease, the USA National Kidney Foundation (NKF) now admits in its new position paper published in April 2008. Meanwhile, Kidney Health Australia and Dr John Carnie at the Victorian DHS are digging their heels in and pretending that the health danger does not exist.
The 2006 USA National Research Council review of toxicology of fluoride in drinking water presented some alarming conclusions about subgroups in the population who are more at risk from ingestion of fluoride, even at relatively low fluoride levels in water. One of these subgroups is kidney patients, those with stage 5, 4 or even less advanced stages of chronic kidney disease.
Fluoride & Bone - Skeletal Fluorosis:
Excessive exposure to fluoride causes an arthrtiic bone disease called skeletal fluorosis.
Skeletal fluorosis, especially in its early stages, is a difficult disease to diagnose, and can be readily confused with various forms of arthritis including osteoarthritis, and rheumatoid arthritis.
In the advanced stages, fluorosis can resemble a multitude of bone/joint diseases, including: osteosclerosis, renal osteodystrophy, DISH, spondylosis, steomalacia, osteoporosis, and secondary hyperparathyroidism.
The risk of developing fluorosis, and the course the disease will take, is influenced by the presence of certain predisposing factors, including impaired kidney function; dietary deficiencies; gastric acidity; and repetitive stress.
Research published in 2001 showed that fluoride (F) deposits in the pineal gland with age and is associated with enhanced gland calcification. Eleven aged cadavares were dissected and their pineal glands assayed: "There was a positive correlation between pineal F and pineal Ca (r = 0.73, p<0.02) but no correlation between pineal F and bone F. By old age, the pineal gland has readily accumulated F and its F/Ca ratio is higher than bone.Reference
Re: Dr Carnie claimed that fluoride consumed through fluoridation has virtually no side-effects for anyone, and that the study by Dr Elise Bassin (2006) linking the bone cancer osteosarcoma with fluoride consumpton, is of no concern for Victorian citizens.
Any reader of this website, or the USA's National Research Council (2006) report on 'fluoride in drinking water' is aware that these claims are ridiculous and fly in the face of the best available science.

CHRONIC FLUORIDE TOXICITY SYNDROME
Four recent reviews, from the United States of America (1,2), Australia (3) and New Zealand (4), have concluded that claims that fluoride is an allergen could not be supported from studies undertaken to date, and that the weight of evidence shows that fluoride is unlikely to produce hypersensitivity and other immunological effects.
Thus although all four reports reached a similar conclusion that fluoride was unlikely to produce allergic or hypersensitivity effects, the 1993 reports (2,4) refer to those published in 1991 (1,3) and are not completely independent.
