The causes of excess fluoride
The causes of excess fluoride can be related to the presence of hyperfluorinated waters, as happened in Africa, to the intake of too many supplements, or an excessive dosage, based on fluoride.
They are hardly related to poor nutrition or an unbalanced diet. Since the elimination of excess fluoride occurs via the urine, too malfunction or kidney problems they can cause an excess of fluoride in the body.
Excess of fluoride and nutrition
The dose of fluoride that is taken daily it should never exceed 0,1mg per individual body weight.
As said and as it happens for the fluoride deficiency, the excess of fluoride is hardly attributable to the diet. Fluoride is concentrated in various foods, especially fish (salmon, seafood), black tea, vegetables (even the skin of potatoes contains fluoride), cereals.
In mineral waters the concentrations are very variable, basically close to zero in the trace minerals, higher in the fluorinated ones, where the content of the element can be even higher than 1 mg / l.
