Fluorine: Daily Requirement, Function, Benefits And Food Source That Everyone Should Know

It is known by the following names, calcium fluoride, stannous fluoride, sodium monofluorophosphate, and sodium fluoride.  Fluorine increase bone density, fights infections and reduces the incidence of tooth decay. Fluorine is one the most active element of halogen group. It belongs to the same group of elements as bromine, chlorine, and iodine. It is never found free in nature. In the body, it is found in combination with other constituents of the body. Natural water contains 3-12 mg of Fluoride per litre.

Fluorine is present in almost all tissue, especially the teeth and bones. It is absorbed in the intestines, transported in the blood stream, stored in teeth and bones. Fluorine increases the bioavailability of calcium and helps to buffer acids present in the mouth. Ingested fluorides are completely ionized and rapidly absorbed, and distributed throughout the extra cellular fluid. The level is too low in blood and tissues. It is rapidly excreted in the urine.

Functions of Fluorine in Our Body

  •  Fluorine is essential for the normal mineralization of bones and the formation of dental enamel. Thus 96% of the Fluoride in the body is found in bones and teeth. The Fluorine and Calcium has strong affinity between them and work together, mainly in the outer parts of bones.
  • Fluorine prevents dental caries, by reducing the solubility of the enamel in acids produced by bacteria. A very small amount of it may help in development of tooth, but excess of it causes dental fluorosis-endemic areas.
  • Protects the spleen

Fluorine Deficiency

Deficiency may cause tooth decay, poor eye sight and susceptibility to infection

  • Decay of teeth.
  • Curvature of the spine.
  • Weak eyesight.

Rich Food Sources of Fluoride

Asparagusavocados, brussels sprouts, cabbage, carrots, caraway seed, cauliflower, cucumber, dates, endive, juniper berries, lemon grass, licorice, parsley,  turnip and beet greens, dandelion, sunflower seeds, garlic, spinach, tomatoes, green leafy vegetables, nuts (especially almonds), turnip greens, dandelions and all sea vegetable.

Toxic sources: Fluoride is added to many water supplies and to food processed in areas containing high levels of fluoride. It is added to most toothpastes and may be added to the soil in certain fertilizers. Also found in seafood and oats.

Many have heard of fluoridated water whether through a municipal water supply or purchasing “fluoride waters”. This is typically an inorganic form of fluorine and not the safest way to get this mineral.
