Ndi kuchuluka kwa zinthu zomwe zili m'thupi la munthu, nthaka imakhala yachiwiri basi. Mu thupi lonse la munthu ndi 2-3 magalamu a zinki. Kuchuluka kwake kwakukulu kumayambira mu chiwindi, nthenda, impso, mafupa ndi minofu. Matenda ena okhala ndi zinc ndi maso, prostate gland, spermatozoa, khungu, tsitsi, komanso zala.
Zinc zili m'thupi mwathu makamaka mthupi la mapuloteni, ndipo timayang'anizana ndi mtundu wa ionic. Mu thupi, zinki zimagwirizana ndi mazyzy 300.
Zinc imakhudzidwa ndi ntchito zambiri za thupi la munthu. Tikulemba mndandanda waukulu:
- Kusiyanitsa kwa magulu. Zinc ndi zofunikira kuti magawo osagwirizana ndi maselo azikhala bwino.
- Chitetezo cha mthupi. Zinc zili mu α-macroglobulin - mapuloteni ofunika kwambiri m'thupi la munthu. Zinc ndiyenso zimagwiritsidwa ntchito moyenera pa thymus (thymus) gland.
- Development. Zinc ndizofunika kuti chitukuko cha ana komanso kusamalidwa kwa ziwalo zoberekera ali mwana. Ndifunikanso kuti apange umuna pakati pa amuna ndi oocytes mwa amayi.
- Kuchotsedwanso kwazitsulo zolemera. Zinc zimathandiza kuchotsa zitsulo zina zoopsa kuchokera ku thupi - mwachitsanzo, cadmium ndi kutsogolera.
- Zochita zina. Zinc ndizofunika kwambiri kuti asungidwe masomphenya, kumva kukoma ndi kununkhiza, chifukwa chodzipatula kwa insulini, komanso kuteteza mavitamini A.
Kuperewera kwa zinki m'thupi kumachitika kawirikawiri, koma ngati zichitika, zimadziwonetsera ndi zizindikiro zotsatirazi:
- chitukuko chochedwa;
- kusowa kudya;
- machiritso aatali kwa zilonda;
- kumeta;
- kuphwanya kwa lingaliro la kukoma ndi fungo;
- hypogonadism mwa amuna;
- matenda opatsirana kawirikawiri;
- mavuto a khungu;
- Kufooka kwa masomphenya mu mdima;
- zitsamba zoyera pa misomali.
Kumbali ina, zink zowonjezera zimapanganso mavuto osiyanasiyana (nthawi zina). Tiyeni tiwayitane:
- cholesterol chowonjezeka;
- kuchepetsa kuyamwa kwachitsulo;
- kuchepetsa zamkuwa kuyamwa;
- colic m'mimba;
- kusanza;
- kutsekula m'mimba;
- impso kulephera;
- chiwonongeko cha chiwindi;
- chiwonongeko;
- imfa.
Kuchuluka kwa zinki, monga lamulo, kupereka thupi lalikulu kwambiri kwa zakudya zowonjezera ndi zinc Komabe, kuwonjezera pa zakudya, pali njira zina zopezera zinc mu thupi la munthu.
Mpweya wapamwamba wa zinki unkawoneka kwa odwala omwe amachititsa hemodialysis njira. Kutentha kwa zinc (kupyolera mu nthunzi) kungathenso kupezeka mwa anthu ogwira ntchito ndi makina odzola.
Ndi zinthu ziti zomwe zili ndi zinki zambiri?
Zakudya zomwe zimapezeka muzipinda zambiri zimatanthawuza zinyama. Zina mwa zinthu zopangira zitsulo zimapezekanso, koma zowonjezera zimakhala zochepa - ndiko kuti, zinki sizikugwedezeka ndipo sizigwiritsidwa ntchito ndi thupi moyenera. Kuchokera pa zomwe tatchulazi, padzakhala kuti zakudya zopangidwa ndi zomera sizidzakhala zincini.
Zida zomwe zimakhala ndi zinc ndi zowonjezera zimaphatikizapo oyster ndi mussels. Kuti timvetse mmene zipangizozi zimakhalira ndi zinc, timatchula zotsatirazi: oyster mmodzi yekha amatha kupeza pafupifupi 70 peresenti ya zosowa za tsiku ndi tsiku za munthu wamkulu mu zinc.
Zakudya zambiri zinc (mg / 100 g):
- oyster atsopano: 45-75;
- mussels: 21;
- nyongolosi ya tirigu, chimanga: 13-16;
- Mtedza wa Brazil: 7;
- nyama yofiira: 4,5-8,5;
- tchizi "Cheddar": 4;
- nandolo: 4;
- hazeliti: 3.5;
- dazira yolk: 3.5;
- sardines: 3.5;
- lenti: 3,1;
- nkhuku (nyama yakuda): 2.85;
- walnuts: 2.25;
- mkate ndi chimphona: 1.65;
- nandolo yamtengo wapatali: 1.4;
- shrimps: 1.15;
- dzira lonse: 1.1;
- mkaka: 0.75.
Kuchuluka kwake kwa nthaka kumadalira pa kugonana kwa munthuyo ndi msinkhu wake, ndipo ali ndi zotsatirazi:
Obadwa kumene
- Miyezi 0-6: 2 mg / tsiku;
- Miyezi 7-12: 3 mg / tsiku.
Ana ndi achinyamata
- 1-3 zaka: 3 mg / tsiku;
- 4-8 zaka: 5 mg / tsiku;
- 9-13: 8 mg / tsiku.
Amuna
- Zaka 14 ndi pamwamba: 11 mg / tsiku.
Akazi
- 14-18 zaka: 9 mg / tsiku;
- Zaka 19 ndi pamwamba: 8 mg / tsiku.
Onani kuti mlingo wokwanira kwambiri wa nthaka ndi 15 mg / tsiku. Pakati pa mimba, kufunika kwakuwonjezeka.
