Amanqanaba aphezulu eVitamin D aDityaniswe noMngcipheko wokuFa
Umxholo
Siyazi ukuba ukunqongophala kukavithamini D ngumba obaluleke kakhulu. Emva koko, uphando oluthile lubonisa ukuba i-avareji, i-42 ipesenti yabantu baseMerika banengxaki yokunqongophala kwevithamin D, enokukhokelela kumngcipheko wokufa kwimiba efana nomhlaza kunye nesifo senhliziyo, kunye nezinye iingozi zempilo ezingaqhelekanga. Nangona kunjalo, i-D echaseneyo-encinci kakhulu inokuba yingozi, ngokutsho kophononongo olutsha lweYunivesithi yaseCopengahen efumene, okokuqala, unxibelelwano phakathi phezulu amanqanaba evithamini D kunye nokufa kwentliziyo. (Ewe ulungelelwaniso alulingani ne-causation, kodwa iziphumo zisamangalisa!)
Oososayensi bafunde inqanaba levithamini D kubantu abangama-247,574 kwaye bahlalutya inqanaba labo lokufa kwisithuba seminyaka esixhenxe emva kokuthatha isampulu yegazi yokuqala. "Siye sajonga ukuba yintoni ebangele ukusweleka kwezigulana, kwaye xa amanani engaphezulu kwe-100 [i-nanomoles ilitha nganye (nmol / L)], kubonakala ngathi kukho umngcipheko owandayo wokufa ngenxa yokubethwa sistroke okanye nge-coronary," watsho umbhali uPeter Schwarz, MD uthe kumaphephandaba.
Njengazo zonke izinto ebomini, xa kuziwa kumanqanaba e-vitamin D, konke malunga nokufumana indawo eyonwabileyo. "Amanqanaba kufuneka abephakathi kwama-50 no-100 nmol / L, kwaye isifundo sethu sibonisa ukuba ama-70 lelona nqanaba likhethwayo," utshilo uSchwarz. (AmaZiko ezeMpilo eSizwe afika ngaphantsi kakhulu ngenani lawo, echaza ukuba i-50 nmol / L igubungela iimfuno ze-97.5 ekhulwini labemi, kwaye i-125 nmol / L "inqanaba eliphezulu eliyingozi".
Ke konke oku kuthetha ntoni? Ewe, kuba amanqanaba e-vitamin D axhomekeke kwizinto ezininzi ezinjengebala lolusu kunye nobunzima, kunzima ukwazi ngaphandle kokufumana uvavanyo lwegazi. Nje ukuba uyazi ukuba ufumana kakhulu okanye umncinci kakhulu, uya kuba nakho ukukhetha idosi ye-IU efanelekileyo kuwe. (Apha, ulwazi oluthe kratya kwibhunga likavithamini D malunga nendlela yokuchaza iziphumo zegazi). Ude ufumanise amanqanaba akho, kuphephe ukuthatha ngaphezulu kwe-1,000 IU ngosuku kwaye ulumkele iimpawu ze-vitamin D yetyhefu, njengesicaphucaphu kunye nobuthathaka, u-Tod Cooperman, umongameli we-MD wenkampani yovavanyo ezimeleyo i-ConsumerLab.com, usixelele emva ngoDisemba. (Kwaye funda ngolwazi oluthe kratya malunga nokuba ungayikhetha njani eyona Vitamin D ilungileyo!)
