Fluoride or fluorine deficiency is a disorder which may cause increased dental caries [1] and possibly osteoporosis, [2] [3] due to a lack of fluoride in diet. [4] [5] Common dietary sources of fluoride include tea, grape juice, wine, raisins, some seafood, coffee, and tap water that has been fluoridated. [6]
In November 2006 the American Dental Association published information stating that water fluoridation is safe, effective and healthy; that enamel fluorosis, usually mild and difficult for anyone except a dental health care professional to see, can result from ingesting more than optimal amounts of fluoride in early childhood; that it is safe ...
Symptoms are mainly promoted in the bone structure. Due to a high fluoride concentration in the body, the bone is hardened and thus less elastic, resulting in an increased frequency of fractures. Other symptoms include thickening of the bone structure and accumulation of bone tissue, which both contribute to impaired joint mobility.
But a fluoride level of above 1.5 mg/L is found in wells and community water systems that serve over 2.9 million people in the U.S., according to the study authors. Further, the study notes ...
But this latest finding joins plenty of other studies about what, exactly, is in drinking water, from concerns about excess levels of fluoride to the discovery of plastic particles (about 240,000 ...
Fluoride levels in China and other countries tend to be much higher than in the U.S., the researchers noted. Fluoride has been added to public water supplies in the U.S. for decades.
The fluoride ion is readily absorbed by the stomach and intestines. Ingested fluoride forms hydrofluoric acid in the stomach. In this form, fluoride crosses cell membranes and then binds with calcium and interferes with various enzymes. Fluoride is excreted through urine. Fluoride exposure limits are based on urine testing, which is used to ...
A new report that analyzes research on fluoride and IQ scores finds that the more fluoride a child is exposed to, the lower he or she tends to score on intelligence tests. The findings' relevance ...
