Veelvoorkomende ziekten zouden het gevolg kunnen zijn van een tekort aan vitamine D

Tal van veelvoorkomende gezondheidsproblemen lijken te maken te hebben met een laag gehalte van de 'zonnevitamine' in het bloed. Krijgt u genoeg binnen van deze belangrijke voedingsstof?

Onderzoekers hebben vastgesteld dat de meerderheid van de normale, gezonde personen van alle leeftijden een gebrek aan vitamine D hebben. Dat zou mede een verklaring kunnen zijn voor het algemeen voorkomen van een aantal ziektes die samenhangen met een gebrek aan de 'zonnevitamine'.

Aandoeningen als griep, broze botten (osteoporose) en zelfs diabetes type 2 worden in verband gebracht met een tekort aan vitamine D. Volgens gepubliceerde studies hebben maar liefst twee op de drie Europeanen een te laag gehalte aan vitamine D in hun bloed.

Belangrijk voor gezonde botten

Dat is vooral zorgwekkend met het oog op de gezondheid van het beendergestel, want een van de taken van vitamine D is het bevorderen van een goede mineralisatie, groei en vorming van botweefsel. Bij een tekort aan vitamine D in de bloedstroom neemt het risico toe dat er dunne, broze of misvormde botten ontstaan.

Ondersteunt het hele lichaam

Er zijn tal van andere functies die afhankelijk zijn van de aanwezigheid van vitamine D. Dat is bijvoorbeeld het geval met ons immuunsysteem en de spierfunctie, maar er zijn nog meer lichaamsfuncties die een zekere hoeveelheid vitamine D nodig hebben om goed te kunnen werken.
