Ukuthola inani elanele likavithamini D novithamini K kubalulekile empilweni yakho.

Kepha eminye imithombo ithi ukwengeza nge-vitamin D kuyingozi uma unovithamini K. omncane.

Yini iqiniso? Lo mbhalo ubheka isayensi ngemuva kwalezo zimangalo.

Ayini amavithamini D no-K?

Uvithamini D novithamini K kubalulekile, okunomsoco oncibilikiswa ngamafutha.

Ngokuvamile kutholakala kakhulu ekudleni okunamafutha amaningi, futhi ukumuncwa kwawo egazini kuyakhula lapho kudliwa ngamafutha.

Imvamisa ibizwa ngokuthi "uvithamini welanga," uvithamini D unenqwaba yezinhlanzi ezinamafutha nezinhlanzi zamafutha, kodwa futhi ikhiqizwa isikhumba sakho lapho sivezwa yilanga.

Omunye wemisebenzi eyinhloko kavithamini D ukukhuthaza ukumuncwa kwe-calcium nokugcina amazinga e-calcium anele egazini lakho. Ukushoda kukavithamini D kungadala ukulahleka kwethambo.

Uvithamini K utholakala emifinini enamaqabunga, imidumba nemifino ebilisiwe, kanye nakokunye okunamafutha, ukudla okutholwe yizilwane, njengeqanda leqanda, isibindi noshizi.

Kuyadingeka ekunqandeni igazi futhi kukhuthaze ukuqoqwa kwe-calcium emathanjeni nasemazinyweni akho.

Amavithamini D no-K yizakhi zomzimba ezincibilikayo ezidlala indima ebalulekile emzimbeni womzimba we-calcium.

Amavithamini D no-K Sebenza Njengeqembu

Uma kukhulunywa nge-calcium metabolism, amavithamini D no-K basebenza ndawonye. Bobabili badlala indima ebalulekile.

Indima kaVithamini D

Omunye wemisebenzi esemqoka kavithamini D ukugcina amazinga e-calcium anele egazini.

Kunezindlela ezimbili i-vitamin D engakufeza ngayo lokhu:

• Ukuthuthukisa ukumuncwa kwe-calcium: IVitamin D ithuthukisa ukumuncwa kwe-calcium ekudleni okudlayo ().
• Ukuthatha i-calcium ethanjeni: Uma ungadli i-calcium eyanele, uvithamini D ugcina amazinga egazi lawo ngokudweba kokuphakelayo kwe-calcium emzimbeni - amathambo akho ().

Ukugcina amazinga egazi anele e-calcium kubalulekile. Ngenkathi i-calcium yaziwa kakhulu ngendima yayo empilweni yethambo, ineminye imisebenzi eminingi ebalulekile emzimbeni ().

Ngesikhathi sokudla i-calcium enganele, umzimba wakho awunakho okunye ongakwenza ngaphandle kokusebenzisa izinqolobane ze-calcium emathanjeni akho, noma lokho kungadala ukulahleka kwamathambo kanye ne-osteoporosis ngokuhamba kwesikhathi.

Indima kaVithamini K

Njengoba kushiwo ngenhla, uvithamini D uqinisekisa ukuthi amazinga egazi e-calcium aphakeme ngokwanele ukuhlangabezana nezidingo zomzimba wakho.

Kodwa-ke, uvithamini D awulawuli ngokuphelele lapho i-calcium emzimbeni wakho iphelela khona. Yilapho i-vitamin K ingena khona.

UVitamin K ulawula i-calcium emzimbeni wakho okungenani ngezindlela ezimbili:

• Iphromotha ukubalwa kwethambo: UVitamin K wenza i-osteocalcin isebenze, iphrotheni ekhuthaza ukunqwabelana kwe-calcium emathanjeni nasemazinyweni akho.
• Yehlisa ukubalwa kwezicubu ezithambile: UVitamin K wenza kusebenze iprotheni ye-matrix GLA, evimbela i-calcium ekuqoqeni izicubu ezithambile, njengezinso nemithambo yegazi (,).

Kuleli qophelo, zimbalwa izifundo zabantu ezilawulwayo ezenze uphenyo ngemiphumela yokwengezelwa ngamavithamini K ekubalweni komthambo wegazi, kepha kwenziwa izifundo eziningi (,,).

Ukubalwa kwesitsha segazi kuyabandakanyeka ekwakhiweni kwezifo ezingamahlalakhona, njengesifo senhliziyo nesezinso (,,).

Omunye wemisebenzi esemqoka kavithamini D ukuqinisekisa amazinga anele we-calcium egazini lakho. IVitamin K ithuthukisa ukuqongelela kwe-calcium emathanjeni akho, ngenkathi inciphisa ukuqoqeka kwayo kwizicubu ezithambile njengemithambo yegazi.

Ingabe uVitamin D Uyingozi Ngaphandle KukaVitamin K?

Abanye abantu bakhathazekile ngokuthi ukudla okuphezulu kukavithamini D kungakhuthaza ukubalwa kwemithambo yegazi kanye nesifo senhliziyo phakathi kwalabo abanevithamini K.

Imigqa eminingi yobufakazi ixhasa lo mbono:

• Uvithamini D ubuthi ubangela i-hypercalcemia: Olunye uphawu lwamazinga aphezulu kakhulu e-vitamin D (ubuthi) yi-hypercalcemia, isimo esibonakala ngamazinga aphezulu ngokweqile we-calcium egazini ().
• I-Hypercalcemia iholela ekubalweni kwemithambo yegazi (BVC): Ku-hypercalcemia, amazinga e-calcium ne-phosphorus aphakama kakhulu kangangokuba i-calcium phosphate iqala ukuqoqana emgqeni wemithambo yegazi.
• I-BVC ihlotshaniswa nesifo senhliziyo: Ngokusho kochwepheshe, ukubalwa kwemithambo yegazi kungenye yezimbangela eziyinhloko zesifo senhliziyo (,).
• Ukushoda kukaVitamin K kuhlotshaniswa ne-BVC: Ucwaningo lokuhlola luxhumanise amazinga aphansi kavithamini K engozini eyengeziwe yokubalwa kwesitsha segazi ().
• Izithako ezinomthamo ophakeme wevithamini K uvimbele i-BVC ezilwaneni: Ucwaningo olulawulwayo kumagundane olusengozini enkulu yokubalwa lubonise ukuthi umthamo owengeziwe wevithamini K2 uvimbele i-BVC ().
• Izithako ze-Vitamin K zinganciphisa i-BVC kubantu: Ucwaningo olulodwa olulawulwayo kubantu asebekhulile lukhombisa ukuthi ukwengeza nge-500 mcg kavithamini K1 nsuku zonke iminyaka emithathu kunciphise i-BVC ngo-6% ().
• Ukudla kakhulu uvithamini K kunganciphisa ubungozi besifo senhliziyo: Abantu abathola inani eliphakeme levithamini K2 ekudleni kwabo basengozini encishisiwe yokubalwa kwemithambo yegazi nesifo senhliziyo (,,).

Kalula nje, ubuthi bukavithamini D bungadala ukubalwa kwemithambo yegazi, kanti uvithamini K ungasiza ukuvimbela lokhu ukuthi kungenzeki.

Yize lezi zintambo zobufakazi zingabonakala zisekela ngokwanele, kusekhona izingcezu ezimbalwa ze-puzzle ezingekho.

Yize imithamo ephezulu kakhulu kavithamini D ingaholela emazingeni aphezulu we-calcium nokubalwa kwesitsha segazi, akukacaci ukuthi imithamo ephansi kavithamini D iyingozi yini esikhathini eside (,,).

Ngo-2007, esinye isazi sokudla okunomsoco saphakamisa ukuthi imithamo ephezulu kavithamini D ingaqeda uvithamini K, okungadala ukuntuleka kukavithamini K. Ucwaningo oluningi luyadingeka ngaphambi kokuba ubuqiniso balo mbono buqinisekiswe ngokuphelele ().

Abukho ubufakazi obuqinile obufakazela ukuthi inani elilinganisiwe likavithamini D liyingozi ngaphandle kokudla okwanele kukavithamini K. Kodwa-ke, ucwaningo luyaqhubeka, futhi isithombe singacaca kungekudala.

Ososayensi abazi ukuthi ukudla okuphezulu kukavithamini D kuyingozi yini lapho ukudla ivithamini K kunganele. Ubufakazi bukhombisa ukuthi kungakhathaza, kepha isiphetho esiqondile asikwazi ukufinyelelwa kuleli phuzu.

Uthola Kanjani Uvithamini K Owanele?

UVitamin K uza ngezindlela eziningi ezahlukene, ngokwesiko ahlukaniswe ngamaqembu amabili:

• Uvithamini K1 (phylloquinone): Uhlobo oluvame kakhulu lwevithamini K. Itholakala ezitshalweni, ikakhulukazi imifino enamaqabunga njenge-kale nesipinashi.
• Uvithamini K2 (menaquinone): Leli fomu liyivelakancane ekudleni futhi litholakala kakhulu ekudleni okutholwe yizilwane nasekudleni okubilile njenge-natto.

UVitamin K2 empeleni ungumndeni omkhulu wezakhi, kufaka phakathi i-menaquinone-4 (MK-4) ne-menaquinone-7 (MK-7).

• I-MK-4: Kutholakala ekudleni okutholwe yizilwane njengesibindi, amafutha, isikhuphasha seqanda noshizi.
• I-MK-7: Kwakhiwa ukuvutshelwa kwamagciwane futhi kutholakala ekudleni okuvutshiwe, njenge-natto, miso ne-sauerkraut. Iphinde ikhiqizwe ngamagciwane akho esiswini (25,).

Izincomo zamanje zokudla azihlukanisi phakathi kukavithamini K1 no-K2. Kubantu abaneminyaka engu-19 nangaphezulu, ukudla okwanele yi-90 mcg yabesifazane kanye ne-120 mcg yamadoda ().

Amashadi amabili angezansi akhombisa imithombo ecebe kakhulu yamavithamini K1 ne-K2, kanye namanani lokhu kudla okukunikezayo ku-100-gram ekhonza (,,,).

Ukungeza okunye kwalokhu kudla ekudleni kwakho kwansuku zonke kungakusiza ukuthi ufinyelele izidingo zakho zevithamini K. Izithasiselo ziyatholakala kabanzi.

Njengoba i-vitamin K incibilika emafutheni, ukuyidla ngamafutha kungathuthukisa ukumuncwa.

Isibonelo, ungangezela uwoyela omncane kwimifino yakho enamaqabunga noma uthathe izithako zakho ngokudla okuqukethe amafutha.

Ngenhlanhla, ukudla okuningi okunevithamini K2 nakho kunothe ngamafutha. Lokhu kufaka phakathi ushizi, izikhupha zamaqanda nenyama.

Ungathathi imithamo ephezulu kakhulu yama-vitamin K ngaphambi kokukhuluma nodokotela wakho, ngoba angaxhumana nemithi ethile ().

UVitamin K1 ugcwele imifino enamaqabunga, eluhlaza, njenge-kale nesipinashi. I-Vitamin K2 itholakala ekudleni okutholwe yizilwane, njengesibindi, amaqanda noshizi, nokudla okuvutshiwe njenge-natto.

Okusemqoka

Ososayensi basaphenya ngemisebenzi kavithamini D noK.

Abaqondi kahle ukuthi basebenzisana kanjani, kepha izingcezu ezintsha ziyanezelwa kancane ku-puzzle.

Kusobala ukuthi uvithamini K uzuzisa inhliziyo namathambo akho, kodwa akucaci ukuthi izithasiselo ezinomthamo omkhulu kavithamini D ziyingozi yini uma uphansi ku-vitamin K.

Noma kunjalo, qiniseka ukuthi uthola inani elanele lakho kokubili uvithamini D no-K ekudleni kwakho. Zombili zibalulekile.
