Izingane ezintula uvithamini D zisemathubeni amaningi okuthi zibe nezifo ezimbi kakhulu futhi ezisongela ukuphila kunezingane ezinamazinga anempilo kavithamini D. Lokhu kuboniswe ucwaningo lwesayensi oluvela e-USA, lapho kwahlolwa khona idatha yezingane ezingaphezu kuka-500 eza egunjini labagula kakhulu phakathi kuka-2009 no-2010 zinezifo ezimbi kakhulu noma ezisongela ukuphila. Amaphesenti angu- alezi zingane ayentula kakhulu uvithamini, obalulekile ekwakhiweni kwamathambo nesimiso sokuzivikela komzimba, phakathi kwezinye izinto.
Ukushoda kwe-Vitamin D kwenza izingane zigule
Ngisho noma umzimba womuntu ungakhiqiza i-vitamin D ngokwayo, abantu abaningi ezindaweni zethu bahlushwa ukuntula kwe-vitamin D. Ukuze kwakheke ivithamini, umzimba udinga imisebe eyanele ye-UVB evela elangeni.
I-Vitamin idlala indima ebalulekile ekwakhekeni kwamathambo, impilo yenhliziyo, namasosha omzimba. Ngakho-ke, ukutholakala kwe-vitamin D okwanele kubalulekile, ikakhulukazi ezinganeni.
Ukushoda kwe-Vitamin D: Okujwayelekile ezinganeni ezindlini zokunakekela kakhulu
uDkt Kate Madden kanye nozakwabo e-Harvard Medical School's Children's Hospital Boston kanye ne-Medical University of South Carolina bahlaziye izibalo zegazi zeziguli ezingaphansi kweminyaka engu-500 ezilaliswe e-ICU zinezifo ezimbi kakhulu noma ezisongela ukuphila kusukela ngoNovemba 2009 kuya kuNovemba 2010.
Izinga elijwayelekile levithamini D lalingu-22.5 ng/ml (ama-nanogram ngemililitha ngayinye). Odokotela abavamile babheka amanani we-30 ng/ml nangaphezulu njenganele, kodwa ngokubuka okuphelele 50 kuya ku-80 ng/ml alungile.
Kodwa-ke, amaphesenti angamashumi amane ezingane ayenamazinga kavithamini D angaphansi kuka-20 ng/ml futhi ngaleyo ndlela ahlushwa ukuntuleka okukhulu kukavithamini D.
Abacwaningi bathole ukuthi ukwehla kwamazinga kavithamini D ezingane, kulapho kunyuka khona ukuqina kwesifo ngosuku lokungeniswa kulo emtholampilo.
Ukuvimbela izifo ezibulalayo nge-vitamin D
UDkt Madden nethimba lakhe bagcizelela ukuthi ukuntuleka kukavithamini D kuvame kakhulu ezinganeni ezigula kakhulu.
Ngakho-ke, batusa ukuba kuqashwe ngokucophelela izindinganiso zegazi lezingane ezinjalo futhi, uma kudingekile, kunikezwe isithasiselo sokudla esinovithamini D. Ukubaluleka okukhulu kukavithamini D empilweni akufanele kuthathwe kancane.
