Abstract
The aim of this study was to determine if streptozotocin-induced diabetes in rats as a model for Type-1 human diabetes causes changes in the levels of fluoride (F) and biogenic elements in the bones and serum in the initial stage of the disease. Twenty-two female Wistar rats were given streptozotocin to induce diabetes; after 10 days the femoral bones and blood were collected for determination of F by potentiometric analysis, Ca and Mg by atomic absorption spectrometry, and estradiol by electroluminescence. At various levels of significance, F, Ca, and Mg increased in the bones. In the serum, F decreased, but Ca, Mg, and estradiol increased. The results indicate that diabetes in the early stages affects uptake of F, Ca, and Mg intake into the bones, which may result in defective crystal formation and an increase of amorphous mineral structure in the bone.

Effects of supplementation with conjugated dienes of linoleic acid on fluoride, calcium, and magnesium levels in hard tissues and serum of mice.
With the recognition of their ability to promote weight loss, conjugated dienes of linoleic acid (CLA) have become the main ingredient of certain dietary supplements to counteract obesity. The results of prospective studies, however, indicate there may be long-term side effects that could be of key importance for the safety

The LD50, excretion and serum and bone levels of F after a high single F and F + Mg dose in rats with findings on cardiac Ca and Mg.
The LD50 for fluoride was elevated from less than 60 mg F/kg body weight to 172 mg F/kg when magnesium (as MgCl2), equivalent to 3 times that of F, was administered by gavage 30 min after the F dose. A dose of 30 mg F/kg elevated the mean steady state

Effect of fluoride on reactive oxygen species and bone metabolism in postmenopausal women.
A study was made of the effects of fluoride (F) on the antioxidant defense systems of postmenopausal women residing in a fluorotic and a nonfluorotic village in Chitoor district, Andhra Pradesh, India. Twenty-five postmenopausal women (approximately 10 years postmenopause, mean age 57 years) residing in endemic fluorotic Adharam and nonfluorotic

Fluoride in Drinking Water: A Scientific Review of EPA’s Standards.
Excerpts: Summary Under the Safe Drinking Water Act, the U.S. Environmental Protection Agency (EPA) is required to establish exposure standards for contaminants in public drinking-water systems that might cause any adverse effects on human health. These standards include the maximum contaminant level goal (MCLG), the maximum contaminant level (MCL), and the secondary

Association between fluoride, magnesium, aluminum and bone quality in renal osteodystrophy
INTRODUCTION: Trace elements are known to influence bone metabolism; however, their effects may be exacerbated in renal failure because dialysis patients are unable to excrete excess elements properly. Our study correlated bone quality in dialysis patients with levels of bone fluoride, magnesium, and aluminum. A number of studies have linked

Fluoride & Osteoarthritis
While the osteoarthritic effects that occurred from fluoride exposure were once considered to be limited to those with skeletal fluorosis, recent research shows that fluoride can cause osteoarthritis in the absence of traditionally defined fluorosis. Conventional methods used for detecting skeletal fluorosis, therefore, will fail to detect the full range of people suffering from fluoride-induced osteoarthritis.

Skeletal Fluorosis: The Misdiagnosis Problem
It is a virtual certainty that there are individuals in the general population unknowingly suffering from some form of skeletal fluorosis as a result of a doctor's failure to consider fluoride as a cause of their symptoms. Proof that this is the case can be found in the following case reports of skeletal fluorosis written by doctors in the U.S. and other western countries. As can be seen, a consistent feature of these reports is that fluorosis patients--even those with crippling skeletal fluorosis--are misdiagnosed for years by multiple teams of doctors who routinely fail to consider fluoride as a possible cause of their disease.

Fluoride & Insulin
Insulin is a hormone produced by the pancreas that is responsible for maintaining appropriate levels of glucose in the blood. Insulin allows the body’s cells to take up glucose from the blood, and either use it as an energy source or store it as glycogen. Blood glucose levels in diabetics
