Fluoride and diabetes linked…

by Dr. Alan Kadish NMD

Recent work has now shown a correlation between the amount and type of fluoride in one’s water and diabetes.  The takeaway from the publication is that added fluoridation to water  is “significantly associated with increases in diabetes”.

Obviously diabetes is a huge and growing concern for a high percentage of Americans. In Benton county they fluorinate the water at a level of .70mg/liter, a low level, but still of  significant  health concern  and well above naturally occuring  levels .

Fluoride in the water has been a consistent issue of health benefit vs health insult and should never have been. One can argue about the potentially positive effect on teeth however this and many other issues completely negate that argument and have published human studies.

If you start to read about fluoridation of water you realize that there is no lack of controversy, however there are numerous (23) human studies and the results are telling, in a negative way. Did you know that most countries don’t fluorinate there water ? On the planet only 24 countries use some flourination and 19 counties have banned it’s use, based on medical issues principally in Europe.  

It’s a waste product of the phosphate fertilizer industry and one of the larger questions that should be asked is since it’s action is on the outside of the teeth why are we drinking it, knowing that the majority gets deposited in our bones and never affects the teeth ? Did we also overlook the fact that the majority of the water lands up in our streams and water systems and it affects the aquatic life.

Let’s consider the cost of fluoride in terms of type 2 diabetes. This is far more health injurious than the enamel issues, which are more a matter of sugar ingestion  and lack of fiber in ones diet. As a society the cost of diabetes is beyond overwhelming from both a fiscal and health prospective.

Fluoride Consumption Linked to Diabetes Using Mathematical Models

Regression analyses suggest association between increases in consumption of fluoridated water and type 2 diabetes

Case Western Reserve University School of Medicine News, 08/22/2016

Water fluoridation prevents dental cavities, which are a costly public health concern. But despite the benefits supplemental water fluoridation remains a controversial subject. Some indicate it may cause long term health problems, but studies reporting side effects have been minimal or inconclusive. The long-term effects of ingested fluoride remain unclear.

A recent study published in the Journal of Water and Health examined links between water fluoridation and diabetes. Type 2 diabetes is a growing epidemic in the United States. Incidence rates have nearly quadrupled in the past 32 years and show no signs of stopping. According to the study, fluoridation with sodium fluoride could be a contributing factor to diabetes rates in the United States, as the chemical is a known preservative of blood glucose.

The sole author of the paper, Kyle Fluegge, PhD, performed the study as a post-doctoral fellow in the Department of Epidemiology and Biostatistics at Case Western Reserve University School of Medicine. Fluegge now serves as health economist in the Division of Disease Control for the New York City Department of Health and Mental Hygiene and co-director of the Institute of Health and Environmental Research in Cleveland, Ohio.

In the study, Fluegge used mathematical models to analyze publicly available data on fluoride water levels and diabetes incidence and prevalence rates across 22 states. He also included adjustments for obesity and physical inactivity collected from national telephone surveys to help rule out confounding factors. Two sets of regression analyses suggested that supplemental water fluoridation was significantly associated with increases in diabetes between 2005 and 2010.

“The models look at the outcomes of

[diabetes] incidence and prevalence being predicted by both natural and added fluoride,” said Fluegge.

Fluegge reported that a one milligram increase in average county fluoride levels predicted a 0.17% increase in age-adjusted diabetes prevalence. Digging deeper revealed differences between the types of fluoride additives used by each region. The additives linked to diabetes in the analyses included sodium fluoride and sodium fluorosilicate. Fluorosilicic acid seemed to have an opposing effect and was associated with decreases in diabetes incidence and prevalence. Counties that relied on naturally occurring fluoride in their water and did not supplement with fluoride additives also had lower diabetes rates.

The positive association between fluoridation and diabetes was discovered when Fluegge adjusted fluoride exposure levels to account for estimated per capita tap water consumption.

“The models present an interesting conclusion that the association of water fluoridation to diabetes outcomes depends on the adjusted per capita consumption of tap water,” explained Fluegge. “Only using the concentration [of added fluoride] does not produce a similarly robust, consistent association.” For this reason, Fluegge adjusted his calculations to incorporate tap water consumption, instead of sticking to calculations that rely on “parts per million” measurements of fluoride in the water.

Fluegge used several estimations in his study, including calculations of county-level water fluoride levels; per capita county tap water consumption; and county measures of poverty, obesity and physical inactivity. Although he doesn’t suggest the study should trigger policy changes, he does indicate it should serve as a call for additional research on the important association between fluoridation and diabetes.

“This is an ecological study. This means it is not appropriate to apply these findings directly to individuals,” explained Fluegge. “These are population-level associations being made in the context of an exploratory inquiry. And water is not the only direct source of fluoride; there are many other food sources produced with fluoridated water.”

In addition to being found in food like processed beverages or produce exposed to specific pesticides, fluoride is found naturally in water in the form of calcium fluoride. Supplemental fluoride was first added to community water supplies in the 1940s.

Said Fluegge, “The models indicate that natural environmental fluoride has a protective effect from diabetes. Unfortunately, natural fluoride is not universally present in the water supply.”
