Kuti mazai abude zvakanaka muzhizha kana tembiricha yakakwira, zvakakosha kuti pave nekutarisira kwakanaka. Chekutanga, kudyiswa kwehuku kunofanira kugadziriswa zvinoenderana nemamiriro ezvinhu chaiwo, uye kutarisirwa kunofanira kupihwa pakudzivirira kupisa.
Nzira yekudyisa huku dzinoisa mazai muzhizha?
1. Wedzera huwandu hwezvinovaka muviri muchikafu
Muzhizha, kana tembiricha yekunze inopfuura 25℃, kudya huku kunoderedzwa zvichienderana nezvinodiwa. Kudya kwezvinovaka muviri kunodererawo zvichienderana nezvinodiwa, zvichikonzera kuderera kwekugadzirwa kwemazai uye kushaya kunaka kwemazai, izvo zvinoda kuwedzera kwekudya kwekudya.
Munguva yekupisa kwakanyanya, simba rinodiwa nehuku dzinokandira mazai rinodzikiswa ne0.966 megajoules pakirogiramu yemetabolism yechikafu zvichienzaniswa nezvinodiwa pakudyisa. Nekuda kweizvozvo, dzimwe nyanzvi dzinotenda kuti huwandu hwesimba rechikafu hunofanira kuderedzwa zvakakodzera muzhizha. Zvisinei, simba ndiro kiyi yekuona huwandu hwemazai mushure me huku dzinokandira mazaizvatanga kukandira. Kusadya simba rakawanda kunowanzokonzerwa nekushomeka kwekudya panguva yekupisa kwakanyanya, izvo zvinokanganisa kugadzirwa kwemazai.
Ongororo dzakaratidza kuti huwandu hwemazai hunogona kuwedzerwa zvakanyanya kana mafuta esoya akabikwa ne1.5% akaiswa muchikafu panguva yekupisa kwakanyanya kwezhizha. Nekuda kweizvi, huwandu hwechikafu chezviyo chakadai sechibage hunofanira kuderedzwa nemazvo, kuitira kuti chisapfuure 50% kusvika 55%, ukuwo huwandu hwekudya huchifanira kuwedzerwa nemazvo kuti chive nechokwadi chekuti kugadzirwa kwacho kwagara kuripo.
2. Wedzera huwandu hwemapuroteni anowanikwa kana zvakakodzera
Nekuwedzera huwandu hweprotein muzvikafu zvemuviri sezvakakodzera uye kuona kuti maamino acids akaenzana chete ndipo patinogona kugutsa zvinodiwa zveprotein.huku dzinokandira mazaiZvikasadaro, kugadzirwa kwemazai kuchakanganiswa nekuda kwekushaya mapuroteni akakwana.
Huremu hweprotein mukudya kwevanahuku dzinokandira mazaiMunguva inopisa, inofanira kuwedzerwa ne1 kusvika 2 muzana kana tichienzanisa nedzimwe mwaka, zvichisvika pamusoro pe18%. Saka, zvakakosha kuwedzera huwandu hwemakeke ekudya akadai sesoya nedonje rekotoni mumakeke, huwandu hwacho husiri pasi pe20% kusvika 25%, uye huwandu hwemapuroteni emhuka akadai sehove hunofanira kuderedzwa nemazvo kuti zviwedzere kunaka uye kuwedzera kudya.
3. Shandisai zvekudya zvinowedzerwa nekungwarira
Kuti dzidzivise kushushikana uye kudzikira kwekugadzirwa kwemazai kunokonzerwa nekupisa kwakanyanya, zvakakosha kuwedzera zvimwe zvinodzivirira kushushikana muchikafu kana mumvura yekunwa. Semuenzaniso, kuwedzera 0.1% kusvika 0.4% vhitamini C uye 0.2% kusvika 0.3% ammonium chloride mumvura yekunwa kunogona kuderedza zvakanyanya kushushikana kwekupisa.
4. kushandiswa zvine musoro kwechikafu chezvicherwa
Munguva yekupisa, huwandu hwephosphorus mukudya hunofanira kuwedzerwa nemazvo (phosphorus inogona kubatsira mukuderedza kupisa), nepo huwandu hwecalcium mukudya kwehuku dzinoyamwisa huchigona kuwedzerwa kusvika pa3.8%-4% kuti pave necalcium-phosphorus balance sezvinobvira, zvichiita kuti chiyero checalcium-phosphorus chirambe chiri pa4:1.
Zvisinei, calcium yakawandisa muchikafu inokanganisa kunaka kwemhuka. Kuti iwedzere huwandu hwecalcium inodyiwa pasina kukanganisa kunaka kwechikafu chehuku dzinoyamwisa, pamusoro pekuwedzera huwandu hwecalcium muchikafu, inogona kuwedzerwa yoga, zvichiita kuti huku dzikwanise kudya zvakasununguka kuti zvigutse zvinodiwa nemuviri wadzo.
