Fluoride is not OK. When we attended the meeting the US Codex office held prior to the Codex Committee on Nutrition and Foods for Special Dietary Uses 2006 meeting (October 30-November 3, 2006, Chiang Mai, Thailand) we were deeply upset, but not shocked, to learn that the US supported the Codex proposal to put fluoride in infant formula as if it were wholesome and healthy. It is neither. Here are our comments urging the US to change that policy and oppose the addtion of fluoride. You can also read the Press Release on the topic that the Natural Solutions Foundation issued.

CODEX COMMITTEE ON NUTRITION AND FOODS FOR SPECIAL DIETARY USES, 28th SESSION, U.S. DRAFT POSITIONS As of September 8, 2006
The Natural Solutions Foundation strongly urges the United States to oppose the addition of any level of fluoride to infant formula.
Exposure to dangerous levels of fluoride compounds is already endemic and should not be increased by infant exposure to additional fluoride. Serious negative dental, neurological, orthopedic and biochemical changes occur in infants and young children exposed to fluoride with loss of bone, tooth and intellectual functions.
- The National Research Council (National Academy of Sciences) recently concluded that the EPA’s Maximum contaminant level for fluoride should be lowered from the current standard of 4mg per day in order to prevent severe enamel fluorosis, reduce risk of bone fracture and skeletal fluorosis. The NRC also concluded that the EPA should update risk assessment of fluoride to include new data on health risks and better estimates of total exposure for individuals.

- Excessive amounts of fluoride can be ingested from a variety of sources including toothpaste, vegetables and fruits, processed foods and drinks, foods and drinks prepared with fluoridated water, fluoridated water, etc.
- The U.S. Dept of Health and Human Services estimates that children are exposed to between .9 and 3.6 mg of fluoride compound per day from environmental sources. This figure does not include exposure that occurs from air emissions and dermal uptake in bathing or exposure that may occur from pharmaceuticals. This is already dangerously close to upper safety limit of 4mg per day.

- Persons chronically exposed to environmental or industrial fluoride reported symptoms related to impaired central nervous system functioning including impaired cognition and memory, difficulties with concentration, general malaise and fatigue.
Possible mechanisms whereby fluoride could affect brain function include influencing calcium currents, altering enzyme configuration by forming strong hydrogen bonds with amide groups, inhibiting cortical adenylyl cyclase activity and increasing phosphoinositide hydrolysis.

Carcinogenicity
- “Taken together as a whole, the evidence – laboratory, animal, and human – suggests that fluoride could either directly initiate, or contribute to, the development of osteosarcoma in boys under the age of 20.
As acknowledged by the U.S. National Toxicology Program there is a “biological plausibility” of a link between fluoride exposure and osteosarcoma. The biological plausibility centers around three facts: 1) Bone is the principal site of fluoride accumulation, particularly during the growth spurts of childhood; 2) Fluoride is a mutagen when present at sufficient concentrations, and 3) Fluoride can artificially stimulate the proliferation of bone cells (osteoblasts).
In addition to its biological plausibility, there is now a substantive body of evidence indicating that fluoride can in fact induce osteosarcomas in both animals and humans.
Most notably, a recent national case control study conducted by scientists at Harvard University found a significant relationship between fluoride exposure and osteosarcoma among boys, particularly if exposed to fluoridated water between the ages of 6 and 8 (the mid-childhood growth spurt).
The Harvard study’s findings are consistent with the U.S. National Toxicology Program’s congressionally-mandated fluoride/cancer study in rats; the National Cancer Institute’s 1990 analysis of osteosarcoma rates among young males in fluoridated versus unfluoridated areas in the U.S., and the New Jersey Department of Health’s 1992 analysis of osteosarcoma rates among young males in fluoridated versus unfluoridated areas of Central New Jersey.
In addition, two later independent analyses of NCI’s national cancer data also found a relationship between fluoridation and osteosarcoma among young males (Yiamouyiannis 1993; Takahashi 2001).”

23. Rats with fluoride in their bones equivalent to the fluoride content of the bones of humans drinking water with fluoride concentrations above 2 ppm show marginal differences between control animals and dosed animals with respect osteosarcoma, cancer of the oral mucosa, thyroid gland and uterus of rats and the hematopoietic system and liver in mice. Two tumor types, hepatoblastoma and hepatocholan-giocarcinoma, were highly unusual.

- Fluoride is shown to be genotoxic in numerous test systems, a property associated with carcinogens.
Stamm, JW, on behalf of the ADA, NTP Public Hearing on the NTP Technical Report on the toxicology and carcinogenesis studies of sodium fluoride. April 26, 1990.
- Fluoride is a plausible carcinogen:
“The “biological plausibility” of a fluoride-osteosarcoma link is acknowledged in the scientific literature. The 3 key, acknowledged mechanisms supporting the plausibility of a fluoride/osteosarcoma connection are:
1) The preponderance of laboratory evidence indicates that fluoride can be mutagenic when present at sufficient concentrations. Most mutagens are also carcinogens.
2) The bone is the principal site for fluoride accumulation within the body, and the rate of accumulation is increased during periods of bone development. Thus, the cells in the bone, particularly during the growth spurts, may be exposed to some of the highest fluoride concentrations in the body.
3) Fluoride is a ‘mitogen’ – meaning it can stimulate the proliferation of bone-forming cells (osteoblasts). Osteosarcoma is a cancer caused by an abnormal proliferation of the osteoblasts.
Hence, fluoride’s ability to induce mutagenic damage in fluoride-rich environments coupled with its ability to stimulate proliferation of osteoblasts provides a compelling biological basis by which fluoride could cause, or contribute to, osteosarcoma.

- “We observed that for males diagnosed before the age of 20 years, fluoride level in drinking water during growth was associated with an increased risk of osteosarcoma, demonstrating a peak in the odds ratios from 6 to 8 years of age. All of our models were remarkably robust in showing this effect, which coincides with the mid-childhood growth spurt. For females, no clear association between fluoride in drinking water during growth and osteosarcoma emerged.”

- “Significant increases in the frequencies of chromosome aberrations were induced in a dose- and treatment time-dependent fashion when NaF was administered to [rat vertebral bone] cells at 0.5 and 1.0 mM for 24 and 48 h. The results indicate that NaF is genotoxic to rat vertebrae, providing a possible mechanism for the vertebrae, as a target organ of NaF carcinogenesis.”

(21.8 million inhabitants, mainly white) were obtained from IARC data (1978-82, 1983-87, 1988-92)… The incidence rate of bone cancer as the mean of three five-years ASRs was significantly correlated with FD (fluoridated water) only in males, with CIR-100 of 1.22, whereas in 1978-82 it showed a high CIR-100 of 2.53

- “Osteosarcoma presents the greatest a priori plausibility as a potential cancer target site because of fluoride’s deposition in bone, the NTP animal study findings of borderline increased osteosarcomas in male rats, and the known mitogenic effect of fluoride on bone cells in culture. Principles of cell biology indicate that stimuli for rapid cell division increase the risks for some of the dividing cells to become malignant, either by inducing random transforming events or by unmasking malignant cells that previously were in nondividing states.”
National Research Council, (2006), Fluoride in Drinking Water: A Scientific Review of EPA’s Standards, National Academies Press, Washington D.C. p 275.
- “It is biologically plausible that fluoride affects the incidence rate of osteosarcoma, and that this effect would be strongest during periods of growth, particularly in males. First, approximately 99% of fluoride in the human body is contained in the skeleton with about 50% of the daily ingested fluoride being deposited directly into calcified tissue (bone or dentition). Second, fluoride acts as a mitogen, increasing the proliferation of osteoblasts and its uptake in bone increases during periods of rapid skeletal growth. In the young, the hydroxyapatite structure of bone mineral exists as many extremely small crystals each surrounded by an ion-rich hydration shell, providing a greater surface area for fluoride exchange to occur.”

- “…if fluoride were to exert a neoplastic effect, it is reasonable to expect that this might be expressed in a tissue that accumulates fluoride. This would include bone, and, therefore, there is biological plausibility for an association between sodium fluoride administration and the development of bone osteosarcomas.”

- “[T]he carcinogenicity of fluoride is consistent with growth stimulation of osteoblasts, unscheduled DNA synthesis by human fibroblasts, and transformation of embryonal hamster fibroblasts into transplantable sarcoma cells. Osteoblasts are differentiated fibroblasts, and fluoride is accumulated in the skeleton. Therefore, osteosarcoma would be the natural target effect to look for in a cancer bioassay of fluoride, and an excess of osteosarcoma in rats exposed to fluoride in drinking water clearly confirms an a priori hypothesis.”

- “When fluoride exposure increases, the following bone responses generally occur:
1) An increase in the number of osteoblasts
2) An increase in the rate of bone formation
3) An increase in the serum activity of alkaline phosphatase
4) An inhibition of osteoblastic acid phosphatase… The increase in osteoblast proliferation and activity may increase the probability that these cells will undergo malignant transformation.”

- “Because the origin of osteosarcoma is considered to be osteoblastic/osteogenic cells, the ability of sodium fluoride to induce chromosome aberrations in these cells provides a mechanistic basis for the occurrence of osteosarcomas observed in sodium fluoride treated animals in the NTP study. Ingested fluoride is accumulated in bone, suggesting that osteoblastic/osteogenic cells in the bone microenvironment can be exposed to high levels of fluoride during bone formation. Our data and the NTP findings provide evidence that bone can be an organ for NaF carcinogenesis.”

- “Recent studies showing substantial increases in the incidence of bone cancer and osteosarcoma in males (but not females) exposed to fluoride gave us the unique opportunity of using females as a control group to determine whether there is a link between fluoridation and bone cancer in males. Using three different data bases, we found that 1) the bone cancer incidence rate was as much as 0.95 cases a year per 100,000 population higher in males under age 20 living in fluoridated areas; 2) the osteosarcoma incidence rate was 0.85 new cases a year per 100,000 population higher in males under age 20 living in fluoridated areas; and 3) for males of all ages, the bone cancer death rate and bone cancer incidence rate was as much as 0.23 and 0.44 cases higher per 100,000 population, respectively, in fluoridated areas. These findings indicate that fluoridation is linked to an increase in bone cancer and deaths from bone cancer in human populations among males under age 20 and that this increase in bone cancer is probably all due to an increase in osteosarcoma caused by fluoride.”

- “Recently, a national study of drinking water fluoridation at the country level found a significant association with osteosarcoma incidence among males under 20 years of age (Hoover et al., 1991). However, the meaning of the association was questioned by the authors because of the absence of a linear trend of association with the duration of time for which the water supplies were fluoridated… As a follow-up to the study by Hoover et al., a small study of similar design was initiated by the New Jersey Department of Health to compare drinking water fluoridation at the municipal level with the municipal residence of osteosarcoma cases at the time of diagnosis… The study observed an association between fluoridation of water and osteosarcomas among males under 20 years of age in seven Central New Jersey counties.”

The Natural Solutions Foundation strongly recommends that because of the infant-specific, organ-specific and function-specific dangers, alerts and cautions raised by fluoride levels even will within the so-called “safe” exposure levels, and because infant metabolism of fluoride is not well understood, that the United States oppose the inclusion of fluoride at any level in infant formula or any other food for special dietary uses. Infant nervous systems are especially vulnerable to the impact of heavy metals and fluoride accelerates the accumulation of lead and compromises the availability of magnesium and other vital metabolites.
The impact of fluoride on the developing nervous system, apart from any impact due to the potentiation of lead’s impact, is negative, lowering IQ and other essential higher functions. Fluoride is a suspected or likely carcinogen and interferes with crucial enzyme functions and DNA base coupling. Young males appear to be particularly susceptible to osteogenic sarcoma, a deadly disease, when exposed to fluoride. Since it is not clear what the impact of adding fluoride to infant formulas and weaning foods, it would be highly prudent to avoid any levels of this dangerous metal to infant and childhood foods.
Fluoride concentrates in and impairs pineal function with unknown, but possible, long-term increases in pediatric cancers. Fluoride has a strongly negative impact on renal and endocrine function and should be avoided for that reason as well.
Despite the wide-spread belief that fluoride supports and maintains healthy ossification and bone mineralization, the data do not support that conclusion. In fact, mineralization is impaired and fractures are increased with fluoride exposure at levels well within the supposed “safe” levels.
Because of the wide spread negative effects of fluoride on vulnerable, rapidly growing infants and children, and because so many infant-specific questions remain, the Natural Solutions Foundation urges the United States to strongly oppose any level of fluoride in these foods.
Thank you for considering the comments of the Natural Solutions Foundation on fluoridation of infant formula.
