Fluoride (F) - Nutrition Trace Minerals

Fluoride (F)

Fluoride increases one’s resistance to dental caries. It appears to strengthen bones and teeth by making the bone mineral less soluble and thus less inclined to being reabsorbed.

Sources.The principal source of fluoride is fluoridated water (water towhich fluoride has been added). In addition, fish and tea contain fluoride. Com-mercially prepared foods in which fluoridated water has been used during the preparation process also contain fluoride.

Requirements.The requirement for fluoride is given as AI levels(Table 8-8). Fluoride is measured in milligrams.

Deficiency or Toxicity.The deficiency of fluoride can result inincreased tooth decay. Excessive amounts of fluoride in drinking water have been known to cause permanent discoloration or mottling of children’s teeth.
