Namuhla sizokhuluma ngesihloko esizwakala libalele -- uvithamini D, owaziwa nangokuthi "ivithamini yelanga." Iqhaza layo kwezempilo likhulu, ikakhulukazi ekuvimbeleni nasekulawuleni umngane wethu wakudala wesifo sikashukela sohlobo 2. Okulandelayo, ake sembule imfihlakalo kavithamini D futhi sibone ukuthi ingabamba iqhaza kanjani empilweni yethu! Siyini isifo sikashukela sohlobo 2? Okokuqala, sidinga ukuqonda ukuthi hlobo luni lwesifo sikashukela sohlobo 2. Ngamagama alula, uhlobo lwesifo sikashukela sohlobo 2 yisifo lapho umzimba ungaphenduli kahle ku-insulin, okuholela ekwenyukeni kukashukela egazini. Cabanga nge-insulin “njengethwala ushukela wegazi” womzimba, esiza ekuhambiseni ushukela osegazini lapho kudingeka khona amandla. Kodwa-ke, lapho u-porter eteleka noma engasakhiqizi kahle, ushukela wegazi uyanqwabelana, okubangela ushukela ophakeme, okungabangela isifo sikashukela sohlobo lwesibili ngokuhamba kwesikhathi. I-Vitamin D idlala indima enkulu emizimbeni yethu. Akugcini nje ngokusisiza ukuthi sibambe i-calcium futhi sigcine impilo yamathambo, futhi idlala indima ebalulekile empilweni ye-metabolic kanye ne-cardiovascular. Ikakhulukazi kulabo abanesifo sikashukela sohlobo 2 noma abasengozini, uvithamini D ungumnakekeli wezempilo ongabonakali.

Ngabe uvithamini D usithinta kanjani isifo sikashukela sohlobo 2? I-insulin iyihomoni eyinhloko ekulawuleni ushukela egazini, futhi uvithamini D ushukumisa amaseli e-beta kumanyikwe ukuthi ahlanganise futhi akhiphe i-insulin eyengeziwe. Kufana nokunikeza "abathwali beshukela egazini" inkulumo-ze, okubenza basebenze kanzima ukuze behlise amazinga kashukela egazini. Kwesinye isikhathi, ngisho nalapho ukukhiqizwa kwe-insulin kujwayelekile, imizimba yethu ingase ingazweli ku-insulin, okubizwa ngokuthi ukumelana ne-insulin. I-Vitamin D ikhulisa ukuzwela komzimba ku-insulin, okwenza "abathwali bakashukela egazini" basebenze kahle futhi kube lula ukulawula ushukela wegazi. Ukunciphisa ukuvuvukala nokucindezeleka okwenziwe nge-oxidative Ukuvuvukala nokucindezeleka okwenziwe nge-oxidative yizici ezibalulekile ekuthuthukiseni nasekuqhubekeleni phambili kwesifo sikashukela sohlobo 2. I-Vitamin D inemiphumela elwa nokuvuvukala kanye ne-antioxidant futhi iyakwazi ukunciphisa amazinga ezici zokuvuvukala kanye nokucindezeleka okwenziwe nge-oxidative emzimbeni, ngaleyo ndlela ivikele amangqamuzana ethu e-beta e-pancreatic nezinye izicubu ezizwela i-insulin emonakalweni.

Izinzuzo zezithako ze-Vitamin D kubantu abanesifo sikashukela soHlobo lwe-2 Njengoba i-vitamin D imangalisa kangaka, yiziphi izinzuzo ze-vitamin D supplements kubantu asebevele benesifo sikashukela sohlobo lwe-2? Ucwaningo oluningi luye lwabonisa ukuthi izithako ze-vitamin D zingasiza abantu abanesifo sikashukela sohlobo 2 ukulawula kangcono amazinga kashukela egazini. Lokhu akubonwanga kuphela ngokuzila ukudla okuphansi kanye noshukela wegazi we-postprandial, kodwa nasemazingeni aphansi e-glycosylated hemoglobin (HbA1c). IHemoglobin A1C iyinkomba ebalulekile yesilinganiso sezinga likashukela egazini ezinyangeni ezi-2-3 ezedlule, futhi ukwehla kwalo kusho ukuthi ushukela wegazi wesiguli ulawuleka kangcono. Izinkinga zohlobo lwesifo sikashukela sohlobo 2 zingaba yikhanda elibuhlungu, okuhlanganisa nesifo senhliziyo, isifo sezinso, i-neuropathy, ne-retinopathy. Ngenhlanhla, izithako ze-vitamin D zingasiza ukunciphisa ingozi yalezi zinkinga. Isebenza ngokuthuthukisa ukusebenza kwemithambo yegazi, ukuvikela izinso, ukukhulula ubuhlungu bezinzwa nokunciphisa i-retinopathy, phakathi kwezinye izindlela. I-Dyslipidemia iyinkimbinkimbi evamile yohlobo 2 lwesifo sikashukela kanye nesici esibalulekile esiyingozi sesifo senhliziyo. Ucwaningo luye lwathola ukuthi amazinga e-vitamin D anganele ahlotshaniswa namazinga e-lipid angalungile, kuyilapho amazinga anele kavithamini D esiza ukuthuthukisa amazinga e-lipid futhi anciphise ingozi yesifo senhliziyo.

Okwesihlanu, ungengeza kanjani uvithamini D? Njengoba uvithamini D muhle kakhulu, singayengeza kanjani? Ukuchayeka elangeni ku-vitamin D kwaziwa ngokuthi "i-vitamin D yokukhanya kwelanga", futhi njengoba igama libonisa, ukukhanya kwelanga kuyindlela elula futhi eqondile yokwengeza i-vitamin D. Ukuchayeka kwelanga imizuzu engu-20-30 ngosuku (ukugwema ilanga lasemini) kuvumela umzimba ukuba uhlanganise i-vitamin D eyanele. Nokho, qiniseka ukuthi ugqoka i-sunscreen futhi ungazishisi! Izithako zokudla Ngaphezu kokuchayeka elangeni, singakwazi futhi ukwengeza uvithamini D ngokudla. Okunye ukudla okunothe ngovithamini D kuhlanganisa amafutha esibindi se-cod, izikhupha zamaqanda, ubisi, nenhlanzi (njenge-salmon, i-mackerel, ne-tuna). Nokho, kubalulekile ukuqaphela ukuthi inani likavithamini D ekudleni lilinganiselwe, futhi kunzima ukuhlangabezana ngokugcwele nezidingo zomzimba. Izithako ze-Vitamin D ziyisinqumo esihle kulabo abangakwazi ukuhlangabezana nezidingo zabo ze-vitamin D ngokuchayeka elangeni nokudla. Kodwa-ke, ngaphambi kokuthatha izithasiselo, kungcono ukubonana nodokotela noma udokotela wezokudla ukuze uqinisekise ukuthi umthamo owuthathayo uphephile futhi uyasebenza.

Nakuba i-vitamin D inezinzuzo eziningi empilweni yethu, okuningi akuhlali kungcono. Ukudla kakhulu uvithamini D kungase kubangele imiphumela engemihle njenge-hypercalcemia. Ngakho-ke, lapho ufaka i-vitamin D, qiniseka ukuthi ulandela umthamo onconywayo emiyalweni kadokotela noma imiyalelo, futhi ungasebenzisi ngokweqile ngokungaboni. Ngaphezu kwalokho, kulabo asebevele behlushwa i-hypercalcemia, amatshe ezinso noma ezinye izifo ezihlobene ne-vitamin D metabolism, kubalulekile ukubonana nodokotela ngaphambi kokuthatha izithako ze-vitamin D ukuze ugweme ukubhebhethekisa lesi simo. Sengiphetha, i-vitamin D, "njengevithamini yelanga", idlala indima ebalulekile ekuvimbeleni nasekulawuleni isifo sikashukela sohlobo 2. Ngokufaka kahle uvithamini D, singalawula kangcono amazinga kashukela egazini, sinciphise ingozi yezinkinga, futhi sithuthukise amazinga e-lipid. Yiqiniso, ngaphezu kwezithako ze-vitamin D, ukulondoloza indlela yokuphila enempilo nakho kubaluleke kakhulu! Ngethemba ukuthi wonke umuntu angaba nempilo enempilo nenelanga!
