Ngomlinganiselo womxholo omzimba womntu, i-zinc yesibini isetya kuphela. Ingqele emzimbeni womntu i-2-3 gram ye-zinc. Isantya sazo esikhulu sisigxina kwisibindi, ipeni, izintso, amathambo kunye nezihlunu. Ezinye izicubu ezinomxholo ophezulu we-zinc zamehlo, i-prostate gland, i-spermatozoa, isikhumba, iinwele, kunye neminwe kunye neenzwane.
I-Zinc inomzimba wethu ikakhulukazi kwiimeko ezinxulumene neeprotheni, kwaye ingxinano yayo encinane esiyifumana kwifomu ye-ionic. Emzimbeni, i-zinc iyanxulumana nama-enzymes ama-300.
I-Zinc ibandakanyeka kwimisebenzi eminingi yomzimba womntu. Silula uluhlu oluphambili:
- Ulwahlulo lweselula. I-Zinc iyimfuneko yokwahlukana kweeseli kunye nokusebenza.
- Amajoni omzimba. I-Zinc iqulethwe kwi-α-macroglobulin-iprotheni ebalulekileyo yesistim somzimba somntu. I-Zinc nayo iyimfuneko ekusebenzeni ngokuqhelekileyo kwe-thymus (thymus) gland.
- Phuhliso. I-Zinc iyimfuneko ekuphuhlisweni kwabantwana kunye nokuzalisa ngokugcwele izitho zokuzala ekukhuleni. Kufuneka kwakhona ukuveliswa kwesilisa kumadoda kunye ne-oocytes kubasetyhini.
- Ukuxutywa kwempahla yesinyithi esinzima. I-Zinc inceda ukususa izitya ezinobuthi ezisuka kumzimba - umzekelo, i-cadmium kunye nekhokelo.
- Ezinye izenzo. I-Zinc ibaluleke kakhulu ekulondolozweni kombono, ukuqonda ukunambitheka kunye nokuvumba, ukuxhoma kwe-insulin, kwakunye nokuxutywa kunye nokuxutywa kwe-vitamin A.
Ukungabikho kwe-zinc emzimbeni kubonakala kunqabile, kodwa ukuba kwenzeka, kuyazibonakalisa ngeempawu ezilandelayo:
- phuhliso lucotha;
- ukungabi nesidlo;
- ukuphilisa ixesha elide lamanxeba;
- ukuguqa;
- ukuphulwa kombono wengongoma kunye nephunga;
- u-hypogonadism kumadoda;
- izifo ezithathelwanayo rhoqo;
- iingxaki zesikhumba;
- ubuthathaka bemibono ebumnyameni;
- Amakhanda amhlophe kwiispiki.
Ngakolunye uhlangothi, i-zinc eyimfuneko iphinda ivelise iindidi ezahlukeneyo (ngamanye amaxesha azinzulu). Masibabize:
- kwandisa i-cholesterol;
- ukunciphisa ukuchithwa kwesimbi;
- ukunciphisa ukuthungulwa kwebhedu;
- colic intestinal;
- ukuhlanza;
- isifo sohudo;
- ukuhluleka kwezintso;
- umonakalo wesibindi;
- coma;
- ukufa.
Inani elincinci le-zinc, njengomyalo, ukunikezela emzimbeni omkhulu kakhulu wee-additives zokutya kunye ne-zinc. Nangona kunjalo, ngaphezu kwondlo, kukho ezinye iindlela zokufumana i-zinc emzimbeni womntu.
Umgangatho ophezulu we-zinc wabonwa kwizigulane ezenza inkqubo ye-hemodialysis. Ukutyhefuza i-Zinc (nge-evaporation) nako kwenzeka nakubantu abasebenza ngamashishini okulondoloza.
Ziziphi iimveliso ezinezincinci ezininzi?
Ukutya okunotye kwi-zinc ngokubanzi kubhekisela kwimvelaphi yezilwanyana. Phakathi kweemveliso zityalo, izityebi-zincinci zifumaneka kwakhona, kodwa ukufumaneka kwayo kwinto ephantsi-oko kukuthi, le zinc ayigciniweyo kwaye ayisebenzisi ngumzimba ngendlela eyanelisayo. Ukusuka apha ngasentla kulandela ukuba ukutya okwenziwa ngemveliso yezityalo akuyi kuba nobutyebi kwi-zinc.
Iimveliso ezinomxholo ophezulu we-zinc ziquka i-oyster kunye ne-mussels. Ukuqonda indlela ezi zinto zizityebi ngayo i-zinc, sichaza oku kulandelayo: i-oyster enye inokufikelela kwi-70% yeemfuno zansuku zonke zomntu omdala kwi-zinc.
Imveliso enotye kakhulu kwi-zinc (mg / 100 g):
- ii-oysters ezintsha: 45-75;
- iimbumbulu: 21;
- ingqolowa yengqolowa, i-bran: 13-16;
- Amantonga eBrazil: 7;
- inyama ebomvu: 4,5-8,5;
- ushizi "uCheddar": 4;
- iipayi: 4;
- hazelnut: 3.5;
- isikhupha seqanda: 3.5;
- sardines: 3.5;
- iilentili: 3,1;
- inkukhu (inyama emnyama): 2.85;
- iilnuts: 2.25;
- isonka nge-bran: 1.65;
- ii-turkish peas: 1.4;
- shrimps: 1.15;
- iqanda lonke: 1.1;
- ubisi: 0.75.
Inani eliphakanyisiweyo le-zinc lixhomekeke kwisini somntu kunye nobudala bakhe, kwaye linamanani alandelayo:
Iintsana
- Iinyanga ezi-0-6: 2 mg / ngosuku;
- Iinyanga ezi-7-12: 3 mg / ngosuku.
Abantwana kunye nentsha
- Iminyaka eyi-1-3: 3 mg / ngosuku;
- 4-8 iminyaka: 5 mg / ngosuku;
- 9-13 iminyaka: 8 mg / ngosuku.
Amadoda
- Iminyaka eyi-14 nangaphezulu: 11 mg / ngosuku.
Bafazi
- Iminyaka eyi-14-18: 9 mg / ngosuku;
- Iminyaka engama-19 nangaphezulu: 8 mg / ngosuku.
Qaphela ukuba umthamo ophezulu wokunyamezela we-zinc ngu-15 mg / ngosuku. Ngethuba lokukhulelwa, isidingo sokwandisa.
