Namhlanje siza kuthetha ngesihloko esinelanga elivakalayo-i-vitamin D, eyaziwa ngokuba yi "vitamin yelanga." Indima yayo kwimpilo inkulu, ngakumbi kuthintelo kunye nolawulo lomhlobo wethu wakudala wesifo seswekile. Okulandelayo, makhe sityhile imfihlelo yevithamin D kwaye sibone indlela enokudlala ngayo indima kwimpilo yethu! Yintoni i-Type 2 diabetes? Okokuqala, kufuneka siqonde ukuba yintoni uhlobo lwe-2 yeswekile. Ngamagama alula, uhlobo lwe-2 yeswekile sisifo apho umzimba usabela kakubi kwi-insulin, ekhokelela ekunyukeni kweswekile yegazi. Cinga nge-insulin "njengesithwala iswekile yegazi," inceda ukuthutha iswekile yegazi ukuya apho kufuneka amandla. Nangona kunjalo, xa i-porter iqhubela ugwayimbo okanye iyancipha, iswekile yegazi ikhula egazini, ibangele iswekile yegazi ephezulu, nto leyo inokukhokelela kuhlobo lwe-2 yeswekile ekuhambeni kwexesha. I-Vitamin D idlala indima enkulu kwimizimba yethu. Ayipheleli nje ekusincedeni ukuba sifunxe i-calcium kwaye sigcine impilo yamathambo, ikwadlala indima ebalulekileyo kwimpilo ye-metabolic kunye ne-cardiovascular. Ngokukodwa kwabo banakho okanye basengozini yokuphuhlisa uhlobo lwe-2 yeswekile, i-vitamin D ngumgcini wezempilo ongabonakaliyo.

I-vitamin D ichaphazela njani i-Type 2 yeswekile? I-insulin yi-hormone ephambili ekulawuleni iswekile yegazi, kwaye ivithamin D ivuselela iiseli ze-beta kwi-pancreas ukuba zidibanise kwaye zikhuphe i-insulin eninzi. Kufana nokunika "abathwali beswekile yegazi" intetho ecokisekileyo, ebenza basebenze nzima ukuthoba amaqondo eswekile yegazi. Ngamanye amaxesha, nangona ukuveliswa kwe-insulin kuqhelekileyo, umzimba wethu unokungabi naluvelwano kwi-insulin, ebizwa ngokuba yi-insulin resistance. IVithamin D inyusa ubuntununtunu bomzimba kwi-insulin, yenza "abagcini beswekile yegazi" basebenze ngakumbi kwaye kube lula ukulawula iswekile yegazi. Ukunciphisa ukuvuvukala kunye noxinzelelo lwe-oxidative Ukuvuvukala kunye noxinzelelo lwe-oxidative zizinto ezibalulekileyo ekuphuhliseni nasekuqhubekeni kohlobo lwe-2 yeswekile. I-Vitamin D ineempembelelo ezichasayo kunye ne-antioxidant kwaye iyakwazi ukunciphisa amanqanaba ezinto ezivuthayo kunye noxinzelelo lwe-oxidative emzimbeni, ngaloo ndlela ikhusela iiseli zethu ze-pancreatic beta kunye nezinye izicubu ezithintekayo ze-insulin kumonakalo.

Izibonelelo ze-Vitamin D izongezelelo kubantu abane-Type 2 yeswekile Ekubeni i-vitamin D iyamangalisa kakhulu, yintoni inzuzo yezongezelelo ze-vitamin D kubantu abasele benesifo seswekile se-2? Izifundo ezininzi zibonise ukuba izongezo ze-vitamin D zinokunceda abantu abanesifo seswekile se-2 balawule ngcono amanqanaba eswekile yegazi. Oku akuzange kubonwe kuphela ekuzileni okuphantsi kunye ne-postprandial iswekile yegazi, kodwa nakwizinga eliphantsi le-glycosylated hemoglobin (HbA1c). I-Hemoglobin A1C iyisalathisi esibalulekileyo somgangatho weshukela wegazi kwiinyanga ezi-2-3 ezidlulileyo, kwaye ukuhla kwayo kuthetha ukuba ishukela legazi lesigulane lilawulwa ngcono. Iingxaki zohlobo lwe-2 yeswekile zinokuba yintloko, kubandakanywa nesifo senhliziyo, isifo sezintso, i-neuropathy, kunye ne-retinopathy. Ngethamsanqa, izongezelelo ze-vitamin D zinokunceda ukunciphisa umngcipheko wezi ngxaki. Isebenza ngokuphucula ukusebenza kwemithambo yegazi, ukukhusela izintso, ukukhulula iintlungu zemithambo-luvo kunye nokunciphisa i-retinopathy, phakathi kwezinye iindlela. I-Dyslipidemia yingxaki eqhelekileyo yohlobo lwe-2 yeswekile kunye nomngcipheko obalulekileyo wesifo senhliziyo. Uphononongo lufumene ukuba amanqanaba e-vitamin D awaneleyo adibaniswa namanqanaba e-lipid angathandekiyo, ngelixa amanqanaba aneleyo e-vitamin D anceda ukuphucula amanqanaba e-lipid kunye nokunciphisa umngcipheko wesifo senhliziyo.

Isihlanu, ukongeza njani ivithamin D? Ekubeni i-vitamin D ilungile, sinokuyongezelela njani? Ukukhanya kwelanga kwi-vitamin D kwaziwa ngokuba yi "vitamin yelanga", kwaye njengoko igama libonisa, ukukhanya kwelanga yindlela elula kwaye eyona ndlela ichanekileyo yokongeza i-vitamin D. Ukutshatyalaliswa kwelanga le-20-30 imizuzu ngosuku (ukuphepha ilanga lasemini) kuvumela umzimba ukuba udibanise ngokwaneleyo i-vitamin D. Nangona kunjalo, qiniseka ukuba unxibe i-sunscreen kwaye ungazitshisi! Izongezo zokutya Ukongeza ekukhanyeni kwelanga, sinokongeza i-vitamin D ngokutya. Okunye ukutya okutyebileyo kwivithamin D kubandakanya ioli yecod yesibindi, iqanda leqanda, ubisi, kunye nentlanzi (efana nesalmon, mackerel, kunye netuna). Noko ke, kubalulekile ukuqaphela ukuba isixa sevithamin D ekutyeni silinganiselwe, yaye kunzima ukuhlangabezana ngokupheleleyo neemfuno zomzimba. Izongezelelo ze-Vitamin D lukhetho olufanelekileyo kwabo bangakwaziyo ukuhlangabezana neemfuno zabo ze-vitamin D ngokubeka ilanga kunye nokutya. Nangona kunjalo, ngaphambi kokuba uthathe izongezo, kungcono ukudibana nogqirha okanye i-dietitian ukuqinisekisa ukuba idosi oyithathayo ikhuselekile kwaye iyasebenza.

Nangona i-vitamin D ineenzuzo ezininzi kwimpilo yethu, ngaphezulu akusoloko kungcono. Ukutya okugqithisileyo kwevithamin D kunokubangela iziphumo ebezingalindelekanga ezifana ne-hypercalcemia. Ngoko ke, xa uncedisa i-vitamin D, qiniseka ukuba ulandele i-dosage ecetyiswayo kwimiyalelo kagqirha okanye imiyalelo, kwaye ungagqithisi ngokungaboniyo. Ukongeza, abo sele bephethwe yi-hypercalcemia, amatye ezintso okanye ezinye izifo ezinxulumene ne-vitamin D metabolism, kubalulekile ukudibana nodokotela ngaphambi kokuba uthathe izongezelelo ze-vitamin D ukuphepha ukunyusa imeko. Ekugqibeleni, i-vitamin D, njenge "vitamin yelanga", idlala indima ebalulekileyo ekuthinteleni nasekulawuleni uhlobo lwe-2 yeswekile. Ngokuncedisa ngokufanelekileyo i-vitamin D, sinokulawula ngcono amanqanaba eswekile yegazi, ukunciphisa umngcipheko weengxaki, kunye nokuphucula amanqanaba e-lipid. Ewe kunjalo, ukongeza kwizongezelelo zevithamini D, ukugcina impilo esempilweni nako kubaluleke kakhulu! Ndiyathemba ukuba wonke umntu unokuba nobomi obusempilweni nobunelanga!
