There is no disagreement that too much fluoride has negative health effects, but how much is too much is hotly debated. If the American Dental Association recommended daily dose is used, 1ppm (equivalent to 1mg/day), we can readily see that we are already overdosed on fluoride, even in areas that don't fluoridate the drinking water supply.
There's an abundance of fluoride in our beverages and our foods. It's put there by the use of pesticides and fungusicides by the farming industry. These toxic substances use fluoride compounds because they are very effective at killing bugs, mildew and a variety of creppy crawley things.
Fluoride is fluoride, whether it's used in a pesticide or to fluoridate the water supply.
Here's what scientific journals have to say about fluoride levels in foods and beverages.
Journal of Clinical Pediatric Dentistry; 16:38-40, 1991. Stannard JG et al. Fluoride levels and fluorides contamination of fruit juices. Forty-three ready-to-drink fruit juices were examined for fluoride ion concentration. The fluoride levels of the juices ranged from 0.15 to 6.80 (Gerber White Grape juice). It was found that 42% of the samples had more than 1 ppm of fluoride.
Given that increasing numbers of people are consuming beverages instead of water, fluoride supplementation should not be based solely upon the concentration of the drinking water, but should also consider the amount of different beverages consumed and their fluoride content.
Journal American Dental Association; 127: 895-901, 1996. Kiritsy, MC et al. Assessing fluoride concentrations of juices and juice-flavored drinks. In this study, the authors analyzed 532 juices and juice drinks for fluoride. Fluoride ion concentration ranged from 0.02 to 2.80 parts per million. Children's ingestion of fluoride from juices and juice-flavored drinks can be substantial and a factor in the development of fluorosis.
Journal American Dental Association; 128: 857-63, 1997. Heilman, JR el al. Fluoride concentrations of infant foods. In this study, the authors analyzed the fluoride concentration of 238 commercially available infant foods. Fluoride concentrations ranged from 0.01 to 8.38 micrograms of fluoride per gram, (ppm) with the highest fluoride concentrations found in infant foods containing chicken.
Journal American Dental Association; 130: 1593-99, 1999. Heilman, JR el al. Assessing fluoride levels of carbonated soft drinks. The authors examined the fluoride concentrations of 332 soft drinks. The fluoride levels of the products ranged from 0.02 to 1.28 ppm, with a mean level of 0.72. Fluoride levels exceeded 0.60 ppm for 71 percent of the products.
Fluoride; 30: 142-146, 1997. Burgstahler, AW et al. Fluoride in California wines and raisins. The water-extractable F content of five brands of California raisins varied from 0.83 to 5.20 ppm (mean 2.71 ppm). Elevated F levels in these wines and raisins appear to result from pesticide use of cryolite (Na3AlF6) in the vineyards.
