Izindonga zemithambo yegazi zingaqina futhi zibe sengozini yesifo senhliziyo nemithambo yegazi esisongela ukuphila. I-Vitamin D ingakhulula ukuqina futhi ilungise imithambo yegazi phakathi namasonto ambalwa.
I-Vitamin D ivikela imithambo yegazi
Izifo zenhliziyo nemithambo yegazi zaziwa njengezimbangela ezivame kakhulu zokufa emazweni anezimboni - futhi ukuntuleka kukavithamini D kusakazeke kakhulu lapho. Ukuxhumana phakathi kokuntuleka kwevithamini D kanye nengozi yenhliziyo nemithambo yegazi sekuyisikhathi eside kungenakuphikiswa. Ngoba ucwaningo lukhombisa izindlela ezimbalwa uvithamini D ongavikela ngazo uhlelo lwenhliziyo nemithambo yegazi ezifweni.
- Isibonelo, uvithamini D ulawula lokho okubizwa ngokuthi uhlelo lwe-renin-angiotensin-aldosterone, oluba namandla kakhulu uma kwenzeka ukuntuleka kwevithamini D futhi lunciphise imithambo yegazi, okungaba nomthelela ekuqineni.
- I-Vitamin D iphinde icindezele ukufuduka kwamangqamuzana emisipha abushelelezi odongeni lwemithambo yegazi engaphakathi, ukusebenza kwama-macrophages, kanye nokubalwa kwezindonga zemithambo yegazi. Zonke lezi zinqubo beziyoqina futhi zenze lukhuni izindonga zemithambo yegazi, zicekele phansi ukuguquguquka kwazo, kubangele i-arteriosclerosis futhi ekugcineni kubangele isifo senhliziyo noma unhlangothi.
- Sesichazile futhi lapha (uvithamini D wenhliziyo) ukuthi izifo zenhliziyo nemithambo yegazi ziba ngenxa yokuvuvukala okungapheli emithanjeni yegazi. Ngaphandle kokungondleki kahle, wukuntula kwevithamini D okungaholela kulokhu kuvuvukala, ngoba uvithamini D uvikela ukuvuvukala.
- Njengoba uvithamini D usiza futhi ekulawuleni amazinga e-cholesterol, ivithamini ibalulekile ekuvimbeleni izifo zenhliziyo nemithambo yegazi ngezindlela eziningi.
Ukuqina kwezindonga zemithambo yegazi kuncipha ngemva kwezinyanga ezi-4 kuphela
Ocwaningweni olwenziwa yi-Augusta University eGeorgia/USA, abesifazane abangama-70, bonke asebevele benamazinga ahlukene emithambo yegazi eqinile, banikezwa imithamo ehlukene kavithamini D izinyanga ezi-4. Lolu bekuwucwaningo lokuqala olungahleliwe lwalolu hlobo. Ithole ukuthi ukwesekwa kwe-vitamin D kungathuthukisa ukuqina kwemithambo yegazi ngendlela encike kumthamo.
Labo ababambiqhaza abathole umthamo omkhulu kakhulu (4,000 IU) bathole imiphumela engcono kakhulu, umbhali wocwaningo uDkt. Anas Raed. Kuyathakazelisa ukuthi liphindwe kahlanu inani elituswa ngokusemthethweni (800 IU). Iziphathimandla zezempilo ngokusobala zixwayisa ngemithamo engaba usizo ngempela futhi zelaphe.
Ukuthatha i-4,000 IU ngosuku, abahlanganyeli babhekana nokunciphisa amaphesenti angu-10.4 ekuqinisweni kwemithambo yegazi ezinyangeni ze-4 nje.
“Sinokuncipha okukhulu nokusheshayo kokuqina kwemithambo lapha,” kusho uRaed.
Umthamo onconywe ngokusemthethweni wevithamini D uqhubeka uqinisa imithambo yegazi
I-2,000 IU kavithamini D - namanje ngaphezu kokunconywa ngokusemthethweni - ibe nomthelela omncane. Ukuqina kwemithambo kwehle ngamaphesenti amabili kuphela. Ku-2 IU (njengoba belulekwa iziphathimandla zezempilo zaseMelika) kube nokuwohloka okuncane kwesimo semithambo yegazi. Eqenjini elilawulayo, elingazange lithathe noma iyiphi i-vitamin D, inkinga yanda ngamaphesenti angu-600.
Kakade ngo-2015, uDkt Dong ushicilele ucwaningo olwase lubonise kakade ukuthi umthamo we-4,000 IU we-vitamin D wakwazi ukulungisa ukuntuleka kwevithamini D ngokuphawulekayo futhi ngokushesha kune-2,000 IU. Ngaphezu kwalokho, umthamo ophezulu waba nomthelela onenzuzo kakhulu empilweni yamathambo.
I-Vitamin D yemithambo yegazi
UDkt Dong, uchwepheshe kavithamini D, weluleka ukuchitha okungenani imizuzu engu-15 elangeni nsuku zonke, phakathi kuka-10 ekuseni no-2 ntambama Ukushiswa yilanga kufanele nakanjani kugwenywe. NgokukaDong, ilanga liwumthombo ongcono kakhulu kavithamini D okhona. Njengoba abantu abaningi besemahhovisi noma kwezinye izakhiwo ngaleso sikhathi okukhulunywa ngaso, izithasiselo zikavithamini D ziyindlela engabizi futhi ephephile yokugcina imithambo yegazi iphilile.
Uvithamini D ungathathwa kalula futhi ngendlela eguquguqukayo uma uwuthatha ngendlela yamaconsi, isb. B. uvithamini D3 wehla ngenxa yemvelo esebenzayo. Ukwehla oku-1 nje kuletha i-1,000 IU.
