There is a generally accepted opinion that the main reason for the white spots on the nails is a lack of calcium in the body and the problem is solved with increased intake of this mineral.
However, research conducted by the German Institute of General Medicine in Hanover showed that this opinion is actually a myth.
The doctor from the Institute Ulrike-Junius-Voker explained that the nail is composed of 100 to 150 thin layers, of which only 0.2% contains calcium.
Small nail trauma such as stroke or minor injuries, cause changes to parts of the nail to became visible as discoloration or small pockets of air on their surface.
There are cases where the reason for the appearance of white spots is precisely the lack of calcium, but it is very rare and is associated with patients with severe deficiency of calcium triggered by some other diseases.
In case when the person is fed properly and still has white spots on nails, it is not a lack of calcium – Dr. Junius-Walker.
