Zinc ekudleni
I-Zinc ingumbiwa wamaminerali obalulekile okudingeka ukuthi abantu bahlale bephilile. Kumaminerali wokulandela ngomkhondo, le nto ingeyesibili kuphela eku-ayini ekugxileni kwayo emzimbeni.
I-Zinc itholakala kumaseli emzimbeni wonke. Kuyadingeka ukuze uhlelo lomzimba lokuzivikela (amasosha omzimba) lusebenze kahle. Idlala indima ekuhlukaneni kwamaseli, ukukhula kwamaseli, ukuphulukiswa kwamanxeba, nokonakala kwama-carbohydrate.
I-Zinc nayo iyadingeka ngezinzwa zephunga nokunambitha. Ngesikhathi sokukhulelwa, ebuntwaneni, nasebuntwaneni umzimba udinga i-zinc ukuze ikhule futhi ikhule kahle. I-Zinc futhi ithuthukisa isenzo se-insulin.
Imininingwane evela ekubuyekezweni kwesazi ngezithako ze-zinc ikhombise ukuthi:
- Uma ithathwa okungenani izinyanga ezinhlanu, i-zinc inganciphisa ubungozi bokugula ngumkhuhlane ovamile.
- Ukuqala ukuthatha izithako ze-zinc kungakapheli amahora angama-24 ngemuva kokuqala kwezimpawu ezibandayo kunganciphisa ukuthi izimpawu zihlala isikhathi esingakanani futhi zenze izimpawu zibe nzima kakhulu. Kodwa-ke, ukwesekwa okungaphezu kwe-RDA akunconywa ngalesi sikhathi.
Amaprotheni ezilwane awumthombo omuhle we-zinc. Inkomo, ingulube newundlu liqukethe i-zinc eningi kunezinhlanzi. Inyama emnyama yenkukhu ine-zinc eningi kunenyama elula.
Eminye imithombo emihle ye-zinc amantongomane, okusanhlamvu okuphelele, imidumba nemvubelo.
Izithelo nemifino akuyona imithombo emihle, ngoba i-zinc kumaphrotheni ezitshalo ayitholakali ukuthi isetshenziswe ngumzimba njenge-zinc evela kumaprotheni ezilwane. Ngakho-ke, ukudla okunama-protein amancane kanye nokudla kwemifino kuvame ukuba ne-zinc encane.
I-Zinc isezithombeni eziningi ze-multivitamin nezamaminerali. Lezi zithasiselo zingaqukatha i-zinc gluconate, i-zinc sulfate, noma i-zinc acetate. Akucaci ukuthi ngabe ifomu elilodwa lingcono kunezinye.
I-Zinc ibuye itholakale kweminye imishanguzo etafuleni, njengama-lozenges abandayo, izifutho zamakhala, nama-gel acinene.
Izimpawu zokushoda kwe-zinc zifaka:
- Ukutheleleka njalo
- Hypogonadism kwabesilisa
- Ukulahleka kwezinwele
- Ukudla okungekuhle
- Izinkinga ngomqondo wokunambitha
- Izinkinga ngomuzwa wokuhogela
- Izilonda zesikhumba
- Ukukhula kancane
- Inkinga yokubona ebumnyameni
- Amanxeba athatha isikhathi eside ukuphola
Izithako ze-zinc ezithathwe ngobuningi zingadala uhudo, amajaqamba esiswini, nokuhlanza. Lezi zimpawu zivame ukuvela kungakapheli amahora amathathu kuya kwayishumi wokugwinya izithasiselo. Izimpawu ziyaphela esikhathini esifushane ngemuva kokumisa izithasiselo. Ukudla ngokweqile kwe-zinc kungaholela ekusweleni kwethusi noma i-iron.
Abantu abasebenzisa izifutho zamakhala kanye nama-gel aqukethe i-zinc bangaba nemiphumela emibi, njengokulahlekelwa umuzwa wokuhogela.
UKUFAKA IZIKHOMBISI
Imithamo ye-zinc, kanye nezinye izakhamzimba, inikezwa kwi-Dietary Reference Intakes (i-DRIs) eyenziwe yiFood and Nutrition Board e-Institute of Medicine. I-DRI yigama lesethi yezithenjwa ezisetshenziswayo ukuhlela nokuhlola ukutholwa komsoco kwabantu abaphilile. Lawa magugu, ahluka ngokweminyaka nobulili, afaka:
- I-Dietary Allowance Enconyiwe (i-RDA) - Izinga lokudla nsuku zonke elanele ukuhlangabezana nezidingo zomsoco zabantu abacishe babe ngama-97% kuya kuma-98%. I-RDA iyizinga lokudla elincike ebufakazini besayensi.
- Ukudla okwanele (AI) - Leli zinga liyasungulwa lapho bungekho ubufakazi obanele bocwaningo lwesayensi ukwenza i-RDA. Isethwe ezingeni okucatshangwa ukuthi liqinisekisa ukondleka okwanele.
Ukufakwa Kwezikhombo Zezokudla Zinc:
Izinsana (AI)
- Izinyanga ezingu-0 kuya kwezingu-6: 2 mg / ngosuku
Izingane nezinsana (RDA)
- Izinyanga eziyi-7 kuya kwezingu-12: 3 mg / ngosuku
- Iminyaka eyi-1 kuye kwengu-3: 3 mg / ngosuku
- Iminyaka emi-4 kuya kwengu-8: 5 mg / ngosuku
- Iminyaka eyi-9 kuye kwengu-13: 8 mg / ngosuku
Intsha Nabantu Abadala (RDA)
- Abesilisa, abaneminyaka engu-14 nangaphezulu: 11 mg / ngosuku
- Abesifazane, abaneminyaka engu-14 kuya ku-18: 9 mg / ngosuku
- Abesifazane, abaneminyaka engu-19 nangaphezulu: 8 mg / ngosuku
- Abesifazane abakhulelwe, abaneminyaka engu-19 nangaphezulu: 11 mg / ngosuku (iminyaka eyi-14 kuye kwengu-18: 12 mg / ngosuku)
- Abesifazane abancelisayo, abaneminyaka engu-19 nangaphezulu: 12 mg / ngosuku (iminyaka eyi-14 kuye kwengu-18: 13 mg / ngosuku)
Indlela engcono yokuthola imfuneko yansuku zonke yamavithamini namaminerali abalulekile ukudla ukudla okunomsoco okuqukethe izinhlobo ezahlukene zokudla.
