This circumstance means that most people need to choose meals and snacks that are high in nutrients but low to moderate in energy content; that is, meeting nutrient recommendations must go hand in hand with keeping calories under control.

Time for a New Baseline? Yiamouyiannis "Water Fluoridation and Tooth Decay: Results from the National Survey of U. Schoolchildren", Fluoride ; Although there is good evidence that the decay rate of deciduous teeth is lower among 5-year-olds in fluoridated areas, this reduced tooth decay rate rapidly disappears among 6- and 7-year-olds and is no longer apparent in 8-year-olds.

This temporary reduction may be due to the inhibitory effect of fluoride on tooth eruption which has already been reported see for example S. Pemrolyd, "Deciduous tooth eruption and fluorosis in the case of increased fluorine content in the drinking water", Stomatologiia, Mosk Volume 61, pp.

In any event, there is no reason to believe that the intake of fluoride beyond the age of Chapter 2 nutrient would have any effect on the tooth decay rate. I assume that you are referring to original studies not reviews that looked into these matters and are not just playing word games.

It is obvious that there are hundreds of thousands of animal studies that have not found that fluoride causes e. I mention this only because when the National Cancer Institute was asked, during Congressional Hearings Chapter 2 nutrient fluoride and cancer into produce studies showing that fluoride did not cause cancer, 11 of the 13 references they produced did not even deal with fluoride and cancer.

One of the two studies you claim shows negative results is Voroshilin,which is an apparent translation of his original paper inwhich I had translated.

But even in the paper, the original English summary points out: After a mixture of 0. For comments on the second paper by Martin,see the footnote on page 66 of my book, Fluoride, the Aging Factor enclosed.

Sobels, The effect of fluoride and iodoacetamide on mutation by X-irradiation in mature Spermatazoa of Drosophila, Mutation Research, volume 6, Please explain to me what you mean in your final conclusion " The foregoing letter has not received a reply or even an acknowledgement. With regard to fluoride, anyone familiar with previous US government reports on this subject 1,2 cannot avoid the conclusion that the report under review has as its objective the justification or rationalization of present high intake levels of fluoride by every age group, including pregnant and lactating females, that have been forced upon all by government policy.

This report is a review of selected references and contains errors, omissions, contradictions and biased manipulations of information.

An adequate critique would have to be on a paragraph by paragraph basis thereby leading to the production of a lengthy volume.

This would take resources not available to those whose cause is not favoured, as is the report under review, by the public purse.

A Closer Look at Current Intakes and Recommended Shifts

It is not surprising to note that Health Canada is one of the contributors. A report prepared for Health Canada by a group of Canadian pro-fluoridation dental academicians was published in July It was, in my view, an example of "tainted truth".

Does the Dietary Reference Intakes report present solid replicable evidence that fluoride is a nutrient to be placed alongside calcium, phosphorus, magnesium and vitamin D as a biochemically essential component of the human diet?

Such positive evidence is a sine qua non. The UL, however, may be significant in estimating the possibilities of incurring adverse effects of fluoride which may be classified as a ubiquitous inessential component or a contaminant of the diet.

The report makes it clear p 2 9 that "evidence on which to base an actual requirement for fluoride is scant The AI is based on estimated intakes that have been shown to reduce the occurrence of dental caries maximally in a population without causing unwanted side effects, including moderate fluorosis.

To support this approach, the report presents the often used statement: It also has the unique ability to stimulate new bone formation and, as such, it has been used as an experimental drug for the treatment of osteoporosis.

As a consequence, both reports are forced to present Dean's highly selective studies and graphical representation as the chief support. The authors of the Health Canada Report admitted that the survey of 39, plus US school children by the US National Institute for Dental Research NIDR was the most extensive contemporary study but showed no statistically significant difference between fluoridated and non fluoridated groups.

The report under examination makes no such concession. The authors of the report also deal with the effects which occur at very low intake of fluoride which they term "negative balance".

They are forced to admit p 8 10 that "no data document the effects of long term negative balance on enamel, on salivary or plaque concentration or on caries development. There are no data that show detrimental effects of long-term absence of dietary fluoride.

For these reasons, fluoride cannot be considered a nutrient along with such dietary components as calcium and vitamin D for which substances evidence is clear with regard to both positive contribution to health and negative physiological effects of long term absence. On the basis of their belief in the cariostatic action of fluoride, the authors of this report tabulate Table S 5, p S 11 the "criteria and dietary reference intake values for fluoride by "life stage group".

The Adequate Intake AI for fluoride ranges from 0. It is impossible to see these levels as "adequate" for anything but intoxication poisoning at some early stage for many individuals.

The report states that these values are "set to protect the most sensitive individuals in the healthy general population such as elderly individuals who tend to have a decreased glomerular filtration rate " p S The values range from 0.
