When it comes to fluoride and water fluoridation the facts are indisputable, the public are being repeatedly lied to by public health authorities and elected politicians. In the past week in the Republic of Ireland, Minister for Health with Responsibility for Water fluoridation Alex White stated in parliament that the preponderance of scientific evidence has demonstrated that fluoridation of drinking water is safe. This statement is repeated ad nauseam by the Minister and by senior executives in public health authorities in Ireland. There is absolutely no evidence to support this claim. To demonstrate the European Food Safety Authority commissioned the University of Anglia to undertake an evidence based review of fluoride to establish safe dietary exposure levels. This was a comprehensive review examining all published literature over the past 30 years.
Herein you will find the findings of an EVIDENCE report published by the European Food Safety Authority in May 2012 identifying the health outcomes upon which Dietary Reference Values (DFVs) could potentially be based for fluoride.
This is factual scientific data and demonstrates the utterly false and deliberately misleading statements by Public Health Authorities in Ireland, Australia, NZ, Canada and the United States who claim that the overwhelming scientific evidence demonstrates that fluoridation is safe.
This is what the EFSA report found.
In 2012, the University of East Anglia were contracted by the EFSA to prepare a report on identifying health outcomes upon which Dietary Reference Values (DRVs) could be potentially based for fluoride. The review included examination of scientific studies focused on primary research in humans concerning maintenance of functional competence and the prevention of clinical deficiency and chronic disease upon which DRVs may be based.
Astonishingly, the review concluded that there was a lack of high quality evidence upon which Dietary Reference Values (DRVs) may potentially be based for fluoride. In other words due to a lack of any available quality scientific data or epidemiological studies they do not know what is a safe level or exposure to fluoride.
Bone Health and FluorideIn examining data relating to bone health and fluoride no individual studies of fluoridated water met the study inclusion criteria, since total fluoride intake was not quantified.
Tooth HealthFor tooth health, eight studies were identified as meeting the inclusion criteria for assessment. The majority of studies were conducted on children not adults. Of the five systematic reviews examined which met the criteria for inclusion all agreed that there was insufficient studies of high quality evidence. Only two systematic reviews were identified that addressed water fluoridation and tooth health. These were classified as of moderate quality but with shortcomings in the quality of studies included in terms of study design and assessment of fluoride exposure.
Biomarkers of DiseaseFor biomarkers of disease, only one study was identified examining the influence of fluoride on plasma leptin levels. The study was assessed as being at a high risk of bias.
Fluoride Bioavailability and MetabolismFluoride bioavailability and metabolism, studies were separated into those focused on fluoride bioavailability and metabolism and those focused on fluoride intake and status relationships. Bioavailability and metabolism studies described here relate to the influence of different fluoride forms or nutrient interactions, which may affect fluoride bioavailability and retention.
The review found just 16 studies which focused on fluoride bioavailability and metabolism of these only two were identified as presenting a low risk of bias with the majority being identified as a high risk of bias. Only three studies addressing fluoride metabolism were conducted over the longer-term (>48 hours). All but one of these were conducted on healthy adult subjects.
In total 16 studies were included, 15 were assessed of as being of high risk of bias. Only one study was assessed as being at a moderate, rather than a high risk of bias. There were just three studies which were conducted over the longer term (>48 hour) and all but one of these studies was conducted in healthy adult subjects.
Established Dietary Exposure using BiomarkersIn the review of published literature on the measurement of biomarkers for establishing dietary exposure six studies were identified all of which were assessed as being at high risk of bias. The majority of these studies were conducted on healty young to middle aged adults.
Six studies were included examining concentration of fluoride in breast milk. The concentration of fluoride was highly variable ranging from 4.56-513 μg/l. Living within an area with fluoridated water was the suggested reason for the differences. Only one study directly recorded total maternal dietary intake, using 24 hour weighing of foods and beverages and analysis of samples for fluoride content. Eight of the studies were assessed as being of high risk of bias with one assessed as being at moderate risk of bias.
The EFSA report concluded that there were relatively few studies of good quality regarding fluoride intake, status and/or health endpoints.
For biokinetic data, there was a lack of well-conducted balance studies and long-term supplementation trials, particularly for children, elderly and pregnant women.
The tooth health, the ESFA report concluded that the data were suggestive of a protective role for fluoride in the reduction of dental caries, but systematic reviews in this area acknowledged a lack of high quality intervention trials measuring total fluoride intake, and data were lacking for adult groups.
ConclusionOverall, the EFSA report concluded there was a lack of high quality evidence upon which DRVs may potentially be based for fluoride.
