Fractional urinary fluoride excretion and nail fluoride concentrations in normal, wasted and stunted 4-5 year-old children in Nepal.
Highlights It is suggested that undernourished children may be more likely develop dental fluorosis. Fluoride intake and excretion were measured in normal, wasted and stunted children. Proportion of ingested fluoride excreted via urine was not related to nutritional status. Nutritional status affected fingernail- but not toenail- fluoride concentration. Abstract Introduction It has been suggested that […]

Risk Factors for Fluoride Toxicity in the Black Community
There are several risk factors for fluoride toxicity that are occur at elevated rates in the black community. These risk factors include: Reduced nutrient intake; Higher levels of lead exposure; Higher prevalence of health conditions that render the body more vulnerable to fluoride intake; and Higher intakes of fluoride.

Fluoride Exposure Increases Metabolic Requirement for Magnesium
Fluoride’s toxicity is significantly enhanced in the presence of nutritional deficiencies. Similarly, fluoride exposure increases the body’s requirement for certain nutrients. An individual with a high intake of fluoride, for example, will need a proportional increase in calcium to avoid the mineralization defects (e.g., osteomalacia) that fluoride causes to bone tissue. Fluoride also appears to […]

Fluoride Exposure Increases Metabolic Requirement for Calcium & Vitamin D
It is well known that individuals with nutrient deficiencies are more susceptible to fluoride toxicity, including fluoride’s bone effects. As discussed in the following studies, fluoride increases the skeleton’s need for calcium (and vitamin D) by increasing the amount of unmineralized tissue (osteoid) in the bone. When insufficient calcium and vitamin D is available to […]

Fluoride & Oxidative Stress
A vast body of research demonstrates that fluoride exposure increases oxidative stress. Based on this research, it is believed that fluoride-induced oxidative stress is a key mechanism underlying the various toxic effects associated with fluoride exposure. It is also well established that fluoride’s toxic effects can be ameliorated by exposure to anti-oxidants. One implication of this […]

Fluoride & Rickets
One of fluoride’s most well-defined effects on bone tissue is it’s ability to increase the osteoid (unmineralized bone) content of bone. When bones have too much osteoid, they become soft and prone to fracture — a condition known as osteomalacia. When osteomalacia develops during childhood, it is called “rickets.” The potential for fluoride to cause rickets was first […]

Fluoride Is Not an Essential Nutrient
In the 1950s, dentists believed that fluoride was a “nutrient.” A nutrient is a vitamin or mineral that is necessary for good health. Dentists believed that fluoride ingestion during childhood was necessary for strong, healthy teeth. A “fluoride deficiency” was thus believed to cause cavities, just like a deficiency of calcium can cause osteoporosis, or a deficiency […]

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium, vitamin C, and iodine, while […]
