Ukwazi intlanzi kunye ne-shellfish equlethe i-mercury eninzi iya kukunceda ucwangcise ngcono ukutya kwimenyu yeveki. Ekubeni, nangona i-mercury ekutyeni inokubangela ukuba idliwe ngokugqithiseleyo, akuyimfuneko ukususa oku kutya ngokupheleleyo ekudleni. Ngaphandle kokuba yingcebiso yonyango, njengakwimeko yabasetyhini abakhulelweyo, iintsana kunye nabantwana abancinci.
I-Mercury ikhona ngokwemvelo kwindawo. Ngenxa yesenzo se-microbial, iguqulwa ibe yindawo enobungozi kwimpilo, eyi-methylmercury. Le nto iyona ndlela inetyhefu ye-mercury, kuba i-soluble kwaye inokuqokelela kwizicubu ezinamafutha abantu kunye nezilwanyana. Ngenxa yesi sizathu, kubalulekile ukuba ungadli kakhulu ezinye izilwanyana ezinokuthi ngenxa yezizathu ezahlukeneyo zibe nezixa eziphezulu zemercury Inetyhefu.
Yintoni ingozi yemekyuri?
Ngokukodwa, yi imethylmercury echaphazela kakhulu impilo yabantu. Le nto ichaphazela inkqubo ye-nervous central, inokuwela i-placenta echaphazela ukukhula komntwana ongekazalwa ngexesha lokukhulelwa kwaye iphinde iwele umqobo wegazi-ubuchopho. Oku kunokubangela umonakalo omkhulu kuphuhliso lwe-neural kubantwana abancinci.
Owona mngcipheko mkhulu usekutyiweni kweentlanzi ezinkulu, kwakunye nezinye iishellfish. Oku kungenxa yokuba iintlanzi ezinkulu zitya iintlanzi ezincinci, nto leyo ekhokelela ekuqokeleleni okukhulu kwe-methylmercury phakathi kwezicubu ezinamafutha entlanzi edla inyama. Nangona kunjalo, intlanzi ene-oyile isekukutya okune-asidi ezinamafutha abalulekileyo enefuthe elihle ekukhuleni nasekukhuleni kwabantwana.
Ngoko isincomo sezempilo kukudibanisa ukusetyenziswa kweentlanzi eziluhlaza kunye neentlanzi ezimhlophe. Ngale ndlela, sinako sebenzisa uncedo lokutya okunempilo ngaphandle kokuthatha umngcipheko nge-mercury. Ukucwangcisa ngokuchanekileyo ukufakwa kweentlanzi kwimenyu yentsapho, siya kukuxelela ukuba zeziphi iintlobo zeentlanzi kunye ne-shellfish equkethe i-mercury kakhulu.
Intlanzi kunye ne-shellfish equlethe i-mercury eninzi
Iintlanzi eziqulethe umxholo ophezulu we-mercury yintlanzi enkulu kunye nendala. Ngokomzekelo, zonke iintlanzi kwintsapho yookrebe, ezitya iintlanzi ezincinci. Ke ngoko, ezi ziintlanzi ekufuneka zityiwe kancinci. Ukukhetha ezinye ezincinci, ezifana nesardadi okanye i-trout, ezityebile ngokulinganayo kwiiasidi ezinamafutha kodwa aziyingozi kangako empilweni.
Ezi zi intlanzi kunye noonokrwece kufuneka unciphise kwimenyu yeveki.
- ityhuna yeBluefin: Intlanzi esetyenziswe kakhulu kwaye ixatyiswe kakhulu, kodwa ekufuneka ilawulwe kuba yenye yezona zinomthamo ophezulu we-mercury. Ngokukodwa i-tuna evela kumanzi ashushu.
- Ukrebe: Le ngokungathandabuzekiyo yeyona ngozi inkulu ngokwemigqaliselo yemercury. Ukrebe sisidlwengu esikhulu kwintsapho yeentlanzi kwaye ke impilo icebisa ukuba ungayidli.
- Intlanzi yeswedi: Le yenye yeentlanzi ezityiwa kakhulu, kuba inyama yayo kunye nencasa yayo ingaqhelekanga kwaye abantwana bayayamkela ngcono. Nangona kunjalo, yintlanzi enomxholo ophezulu we-mercury kwaye ngoko ke kucetyiswa ukunciphisa ukusetyenziswa, ngakumbi kubantwana.
- Pike: Intlanzi enkulu, edla inyama ehlala kumanzi amatsha kunye nanetyuwa. Kule meko, kukwacetyiswa ukunciphisa ukusetyenziswa kwabantu abadala kunye nokuphelisa kwimeko yabasetyhini abakhulelweyo kunye nabantwana abancinci.
Intlanzi kukutya okutyebileyo kwaye okunempilo ekufuneka kubekho kuyo nayiphi na ukutya. Ngoku, kubalulekile ukukhetha ukhetho olungcono kwimeko nganye kunye ezinye iintlanzi ezisempilweni ngakumbi nezingacetyiswanga kangako. Ekubeni intlanzi kufuneka idliwe phakathi kwe-3-4 ye-servings ngeveki, nciphisa intlanzi enomxholo ophezulu we-mercury kwi-service enye ukunciphisa umngcipheko. Kwimeko yabasetyhini abakhulelweyo kunye nabantwana abangaphantsi kweminyaka eyi-10 ubudala, kucetyiswa kakhulu ukuba ungayisebenzisi ngokuthe ngqo.
