Fluoride
Fluoride is also an essential trace mineral you need for certain body functions. The majority of it is found in the teeth and bones as calcium fluoride. In this post, we will explore its uses in the body and diet.
Functions Of Fluoride
- Maintain teeth and bone health– Fluoride is necessary in the formation of teeth by enhancing their development and strengthening the tooth enamel during their growth and development.
- For the hardening of bones and teeth-Fluoride is also important for the hardening of bones and teeth. It incorporates into the crystal-like parts of these structures, further hardening them.
RDA
- Adult males -4 milligrams
- Adult females -3 milligrams
Fluoride Deficiency
Inadequate fluoride intake can lead to fluoride deficiency. Fluoride deficiency can further weaken teeth and bones.
Fluoride Toxicity
Fluoride toxicity is rarely a result of dietary intake, and as long as you use oral hygiene products appropriately, you are unlikely to be exposed to toxicity. Excess fluoride is linked to dental fluorosis whereby the teeth become discoloured. In most instances, acute fluoride toxicity causes nausea and vomiting, although it can sometimes be fatal.
Nutrient Interactions With Fluoride
Calcium–To a certain extent, calcium can reduce the absorption of fluoride especially when sources are consumed together.
Drug Interactions With Fluoride
There are no known serious interactions with fluoride and other drugs.
Food Sources
- Beverages e.g. tea and coffee
- Seafood e.g. shrimp
- Fluoridated water
Fluoride is important in the diet especially for teeth and bone health. Its deficiency is unlikely for most population groups as it can be obtained from various dietary sources and is usually added to water and dental products. Consuming it in required amounts should ensure that you are not exposed to its toxicity or deficiency.
