Iindonga zemithambo yegazi zinokuqina kwaye zibeke umngcipheko wesifo sentliziyo esisongela ubomi. I-Vitamin D inokukhulula ukuqina kunye nokulungisa imithambo yegazi kwiiveki ezimbalwa.
I-Vitamin D ikhusela imithambo yegazi
Izifo zentliziyo ziyaziwa njengezona zizathu zixhaphakileyo zokufa kumazwe ahambele phambili kwezoqoqosho- kwaye ukunqongophala kwevithamin D kuxhaphake kakhulu apho. Unxibelelwano phakathi kokunqongophala kwevithamin D kunye nomngcipheko we-cardiovascular sekudala kungaziwa. Kuba izifundo zibonisa iindlela ezininzi apho ivithamin D inokukhusela inkqubo yentliziyo kwizifo.
- Umzekelo, ivithamin D ilawula inkqubo ebizwa ngokuba yi-renin-angiotensin-aldosterone, ethi isebenze ngokugqithisileyo xa kukho ukunqongophala kwevithamin D kwaye icuthe imithambo yegazi, enokuthi ibe negalelo ekuqineni.
- I-Vitamin D iphinda icinezele ukufuduka kweeseli ze-muscle ezigudileyo ukuya kudonga lwegazi olungaphakathi, ukusebenza kwe-macrophages, kunye nokubalwa kweendonga zemithambo yegazi. Zonke ezi nkqubo beziya kuthi zityebe kwaye zenze lukhuni iindonga zemithambo yegazi, zitshabalalise ukuguquguquka kwazo, zikhokelele kwi-arteriosclerosis kwaye ekugqibeleni zibangele ukuhlaselwa yintliziyo okanye ukubetha.
- Kwakhona sele sichazile apha (ivithamin D yentliziyo) ukuba izifo zentliziyo zikhula ngenxa yokudumba okungapheliyo kwimithambo yegazi. Ukongeza kokungondleki kakuhle, kukunqongophala kwevithamin D okunokukhokelela koku kuvuvukala, kuba i-vitamin D ikhusela ukudumba.
- Ekubeni i-vitamin D inceda ukulawula amanqanaba e-cholesterol, i-vitamin ibalulekile ekuthinteleni izifo zentliziyo ngeendlela ezininzi.
Ukuqina kweendonga zemithambo yegazi kuncipha emva kweenyanga ezi-4 kuphela
Kuphononongo olwenziwa yiYunivesithi yase-Augusta eGeorgia/USA, abafazi abangama-70, bonke abo sele bebandezeleke ngamanqanaba ahlukeneyo emithanjeni yegazi eqinile, banikwa iidosi ezahlukeneyo zevithamini D kwiinyanga ezi-4. Olu yayiluphononongo lokuqala olungenamkhethe loluhlobo lwayo. Ifumene ukuba ukuxhaswa kwe-vitamin D kunokuphucula ukuqina kwemithambo yegazi ngendlela exhomekeke kwidosi.
Abo bathathi-nxaxheba abafumene i-dose ephezulu (i-4,000 IU) baphumelele iziphumo ezilungileyo, umbhali wokufunda uDkt Anas Raed. Kuyathakazelisa ukuba kuphindwe kahlanu imali ekucetyiswa ngokusemthethweni (800 IU). Abasemagunyeni kwezempilo ngokucacileyo bayalumkisa ngamayeza anokuba luncedo kwaye aphile.
Ukuthatha i-4,000 IU ngosuku, abathathi-nxaxheba bafumana i-10.4 yepesenti yokunciphisa ukuqina kwemithambo kwiinyanga ze-4 kuphela.
URaed uthi: “Sinokuncipha okukhulu nangokukhawulezayo kokuqina kwemithambo apha.
Idosi yevithamin D ecetyiswa ngokusemthethweni yenza lukhuni ngakumbi imithambo yegazi
I-2,000 IU yevithamini D - isengaphezulu kokucetyiswa ngokusemthethweni - yayinesiphumo esincinci. Ukuqina kwemithambo kwehle ngesi-2 ekhulwini kuphela. Kwi-600 IU (njengoko kucetyiswe ngabasemagunyeni bezempilo baseMelika) bekukho nokuba mandundu kancinci kwimeko yemithambo yegazi. Kwiqela lolawulo, elingazange lithathe nayiphi na i-vitamin D nonke, ingxaki yanda nge-2.3 ekhulwini.
Kakade ngo-2015, uDkt Dong upapashe isifundo esele sibonise ukuba i-dose ye-4,000 IU ye-vitamin D yakwazi ukulungisa ukusilela kwe-vitamin D ngokubonakalayo ngcono kwaye ngokukhawuleza kune-2,000 IU. Ukongezelela, idosi ephezulu yayinempembelelo enenzuzo ngakumbi kwimpilo yethambo.
Vitamin D kwimithambo yegazi
dr Dong, ingcaphephe kuvithamin D, ucebisa ukuba uchithe ubuncinane imizuzu eli-15 elangeni yonke imihla, phakathi kwentsimbi ye-10 kusasa neye-2 emva kwemini Ukutshiswa lilanga kufuneka ngokuqinisekileyo kuthintelwe. Ngokutsho kukaDong, ilanga ngowona mthombo we-vitamin D okhoyo. Kuba abantu abaninzi beseziofisini okanye kwezinye iindawo ngelo xesha ekuthethwa ngalo, izongezo zevithamin D ziyindlela engabizi kakhulu nekhuselekileyo yokugcina imithambo yegazi isempilweni.
IVithamin D inokujongwa ngokulula nangokuguquguqukayo ukuba uyithatha ikwimo yamathontsi, umz. Ukuwisa nje oku-3 kuzisa i-1 IU.
