Selenium ekudleni

I-Selenium iyimbiwa ebalulekile yokulandela umkhondo. Lokhu kusho ukuthi umzimba wakho kufanele uthole le minerali ekudleni okudlayo. Inani elincane le-selenium lilungele impilo yakho.

I-Selenium iyimbiwa yamaminerali. Umzimba wakho udinga kuphela ngamanani amancane.

I-Selenium isiza umzimba wakho ukwenza amaprotheni akhethekile, abizwa ngama-enzyme e-antioxidant. Lokhu kudlala indima enkulu ekuvikeleni ukulimala kwamangqamuzana.

Olunye ucwaningo lukhombisa ukuthi i-selenium ingasiza kulokhu okulandelayo:

• Vikela umdlavuza othile
• Vikela umzimba emiphumeleni enobuthi yezinsimbi ezisindayo nezinye izinto eziyingozi

Kudingeka izifundo eziningi ngezinzuzo ze-selenium. Njengamanje, ukuthatha isengezo selenium ngaphezu kwemithombo yokudla ye-selenium okwamanje akunconywa ngalezi zimo.

Ukudla kwezitshalo, njengemifino, yimithombo yokudla evame kakhulu ye-selenium. Ukuthi i-selenium engakanani emifinini oyidlayo incike ekutheni amaminerali ayengakanani emhlabathini lapho kwakhula khona izitshalo.

Amantongomane aseBrazil angumthombo omuhle kakhulu we-selenium. Izinhlanzi, izimbaza, inyama ebomvu, okusanhlamvu, amaqanda, inkukhu, isibindi negalikhi nakho kuyimithombo emihle. Inyama ekhiqizwa ezilwaneni ezidle okusanhlamvu noma izitshalo ezitholakala enhlabathini enothe nge-selenium inezinga eliphakeme le-selenium.

Imvubelo kaBrewer, igciwane likakolweni, nezinkwa ezicebile nakho kuyimithombo emihle ye-selenium.

Ukuntuleka kwe-selenium akuvamile kubantu base-United States. Kodwa-ke, ukuntuleka kungenzeka lapho umuntu ondliwa ngomthambo (umugqa we-IV) isikhathi eside.

Isifo iKeshan sidalwa ukungabi khona kwe-selenium. Lokhu kuholela ekungajwayelekile kwemisipha yenhliziyo. Isifo i-Keshan sabangela ukufa kwezingane eziningi eChina kwaze kwaba kutholakala ukuxhumana ne-selenium kwaphinde kwanikezwa nezithasiselo.

Ezinye izifo ezimbili zixhunyaniswe nokushoda kwe-selenium:

• Isifo seKashin-Beck, esiholela ezifweni ezihlangene nezethambo
• I-Myxedematous endemic cretinism, eholela ekukhubazekeni kwengqondo

Izinkinga ezinzima zamathumbu zingaphinde zithinte amandla omzimba okuthola i-selenium. Izinkinga ezinjalo zibandakanya isifo seCrohn.

I-selenium eningi egazini ingadala isimo esibizwa nge-selenosis. I-Selenosis ingadala ukulahleka kwezinwele, izinkinga zezipikili, isicanucanu, ukucasuka, ukukhathala, nokulimala kwezinzwa okuncane. Kodwa-ke, ubuthi be-selenium buyivelakancane e-United States.

Imithamo ye-selenium, kanye nezinye izakhamzimba, inikezwa kwi-Dietary Reference Intakes (DRIs) eyenziwe yiFood and Nutrition Board e-Institute of Medicine. I-DRI yigama lesethi yezithenjwa ezisetshenziswayo ukuhlela nokuhlola ukutholwa komsoco kwabantu abaphilile.

Ukuthi uvithamini ngamunye udinga kangakanani kuya ngeminyaka yakho nobulili bakho. Ezinye izinto, njengokukhulelwa kanye nokugula, nakho kubalulekile. Abesifazane abakhulelwe noma abancelisayo badinga amanani aphezulu. Buza umhlinzeki wakho wezokunakekelwa kwempilo ukuthi yiliphi inani elikulungele kakhulu. Lawa magugu afaka:

• Isibonelelo Esinconyiwe Sezokudla (RDA): Izinga lokudla nsuku zonke elanele ukuhlangabezana nezidingo zomsoco cishe zabo bonke (97% kuya ku-98%) abantu abaphilile. I-RDA iyizinga lokudla elincike ebufakazini besayensi.
• Ukudla okwanele (AI): Leli zinga lisungulwa lapho bungekho ubufakazi obanele bocwaningo lwesayensi ukuthuthukisa i-RDA. Isethwe ezingeni okucatshangwa ukuthi liqinisekisa ukondleka okwanele.

Izinsana (AI)

• Izinyanga ezingu-0 kuya kwezingu-6: ama-micrograms ayi-15 ngosuku (mcg / ngosuku)
• Izinyanga eziyi-7 kuya kwezingu-12: 20 mcg / ngosuku

Izingane (RDA)

• Ubudala 1 kuye ku-3: 20 mcg / ngosuku
• Ubudala 4 kuya ku-8: 30 mcg / ngosuku
• Ubudala 9 kuya ku-13: 40 mcg / ngosuku

Intsha kanye nabantu abadala (RDA)

• Abesilisa, abaneminyaka engu-14 nangaphezulu: 55 mcg / ngosuku
• Abesifazane, abaneminyaka engu-14 nangaphezulu: 55 mcg / ngosuku
• Abesifazane abakhulelwe: 60 mcg / ngosuku
• Izinsikazi ezincelisayo: 70 mcg / ngosuku

Indlela engcono yokuthola imfuneko yansuku zonke yamavithamini abalulekile ukudla ukudla okulinganiselayo okuqukethe izinhlobo ezahlukene zokudla.
