Nginesithakazelo ekwenzeni ukudla kwami ngokwabo, kepha udadewethu wangitshela ukuthi kuyingozi ngenxa yengozi ye-nitrate ekudleni kwezingane. Iyini i-nitrate? Ngingakwazi yini ukwenza ingane yami ukudla?
Yebo, ngenkathi udade wakho ehle ngendlela efanele ukuthi udinga ukuqonda ukuthi yiziphi i-nitrate nokuthi zingalimaza kanjani ingane yakho, akalungile ukuthi awukwazi ukwenza ingane yakho ukudla ngenxa yabo.
Nansi isikhumba kulokho okudingayo ukwazi mayelana nokudla kwezingane okuzenzekelayo nezitrate.
Yiziphi Nitrate?
I-nitrate yikhemikhali engatholakala emanzini nasemhlabathini. Zenzeka ngokwemvelo njengoba isitshalo sehlisa i-nitrogen ngesikhatsi se-photosynthesis, nakuba saziwa nangokuthi senziwa ngezenzo futhi sisetshenziselwa ukulungiselela ukudla okunye. Ama-nitrate atholakala kakhulu kulezi zinhlobo zokudla nokuphuza:
- Imifino eluhlaza emifino.
- Imifino yomsuka.
- Amanzi angaphansi komhlaba kusuka emithonjeni. Abazali balungiselela ifomula yamanzi emanzini ahlanzekile kufanele bakhulume nezingane zabo ngokuphepha.
- Ukudla okunomsoco. Imikhiqizo yenyama ephulukisiwe (cabanga ngunani, izinja ezishisayo, ubhekeni, njll), ingelashwa nge nitrate ezitshalwe ngokwemvelo noma nge nitrate ezakhiwe ngamakhemikhali.
Ama-Nitrate Angamlimaza Kanjani Ingane Yami?
Ngokwemibandela elula, ukufaka okuningi ngokweqile kwe-nitrate kungathinta kabi ukubala kwegazi kwengane yakho. Isikhathi esikhulu sezokwelapha ongase ufunde kuso yi- methemoglobinemia .
Amantombazane aphethwe yi-methemoglobinemia azobonisa ukubhula okwenziwa ngezikhathi ezithile emlonyeni, izandla, nezinyawo. Ngaphezu kwalokho, izinsana zingase zithole ukhathele kunokuba zijwayelekile noma zibe nezinkinga zokuphefumula. Amacala aphezulu angabangela ukulahlekelwa kokuqonda noma ngisho nokufa. Ngenxa yalokhu, kubalulekile ukwazi izinyathelo zokuphepha lapho ukondla ingane yakho ukudla okuzenzekelayo.
Ubani Osebuningi Ngengozini Ye-Nitrate Poisoning?
Yikuphi ucwaningo oluye lwaboniswa ukuthi abantu abasengozini enkulu yokushisa i-nitrate ngabantu abadla amanzi kahle. Amanzi kufanele ahlolwe amazinga e-nitrate. I-American Academy of Pediatrics (AAP) iluleka ukuthi odokotela kufanele baxoxe ngokuhlinzeka ngamanzi nabazali. Imindeni esebenzisa amanzi ahlanzekile ekuphuzeni noma ekusetshenzisweni kwefomula kumele ihlole amanzi awo nge-nitrate. I-AAP itusa ukuthi amazinga we-nitrate kufanele abe ngaphansi kuka-10 ppm.
Ukwengeza, izinsana ezineminyaka engaphansi kwezinyanga ezintathu zithinteka kakhulu kwi-methemoglobinemia. Khona-ke iqembu elilandelayo elisengozini liyizingane ezineminyaka engu-3 kuya kwezingu-6 ubudala. Ngemuva kwezinyanga eziyisithupha ubudala, izifo zesisu zomntwana ziye zathuthuka futhi ngenxa yalokho, zingaphansi kwezinselele ezinkingeni.
Yiziphi iziphakamiso ze-AAP zokuzenzela izingane zokudla?
Ngo-2005, i-Amerian Academy of Pediatrics yakhipha iseluleko sabo sokudla ukudla okwenzelwe izingane. Bathi, "Izinsana ezondla ukudla okwanele ezentengiselwano ezingasetshenziselwa ukuhweba ngokuvamile azikho engozini yokudla ubuthi lwe-nitrate. Kodwa-ke, ukudla okusana okulungiselelwe ekhaya kusuka emifino (isib. Isipinashi, beet, ubhontshisi obomvu, u-squash, izaqathe) kufanele kugwenywe kuze kube yizinsana ezinyangeni ezingu-3 noma asebekhulile , nakuba kungenayo inkomba yokudla okunempilo yokwengeza ukudla okuhambisanayo ekudleni kwezingane ezinempilo ngaphambi kwezinyanga ezine kuya kwezingu-6 ubudala. "
Iphuzu engingayinika lona ukuthi uma usebenzisa imifino ehlanzekile, lungiselela ukudla kwakho uma izigcoko zivuselela ngangokunokwenzeka. Uma behlala isikhathi eside, i-nitrate eyengeziwe iyakha. Ngaphandle kwalokho, sebenzisa izithelo ezinamaqanda nama-veggies, okuvame ukuhlanza kunemifino oyithenga esitolo.
Ingabe Lokho Kusho Ukudla Kwezingane Zokulungiswa Kwezokuhweba Ingabe Akuyona I-Nitrate-Free?
Ungadukiswa ekucabangeni okusho ukuthi ukudla okulungiselelwe ukuthengiswa kwezingane kumele kube yi-nitrate mahhala. Akunjalo. Ama-nitrate ayenzeka ngokwemvelo emigodleni, ukudla okuthengwe ngesitolo kusenokwenzeka ukuthi kuhlolwe yinkampani ukuba ibe ngaphansi kwezinga elithile.
Kodwa-ke, ukuhlolwa akugunyaziwe ngumthetho, futhi izinkampani zamaphoyisa zilawo mazinga ngokuzimela.
