Mhlawumbi uyazi ukuba ukutya okuninzi esikuthenga evenkileni okanye kwivenkile enkulu kunezongezo ezahlukeneyo ezongeziweyo ukuze zihlale zintsha kwaye zigcine incasa yazo. Kodwa ngaba uyazi kakuhle ukuba ezi zongezo ziyichaphazela njani impilo yethu? Namhlanje sithetha ngento exoxwa ngabantu abaninzi. Loo nto yi -sodium nitrate.

Yintoni iSodium Nitrate?
Ngamafutshane, i-sodium nitrate kunye nesalamane sayo esisondeleyo, i-sodium nitrite, zizinto zokugcina ukutya. Zisetyenziswa kakhulu kwiimveliso "zenyama eyosiweyo", ezifana neesoseji, ibhekoni, iham, kunye neenyama zenyama. Zongezwa kungekuphela nje ukugcina inyama ixesha elide, kodwa nokuyenza ibe nombala opinki okhethekileyo kunye nencasa ekhethekileyo.
Kodwa into emangalisayo kukuba ezi nitrates kunye nee nitrites azifumaneki kuphela ekutyeni okongeziweyo okwenziweyo. Zifumaneka ngokwemvelo kwimifuno efana nespinatshi kunye neseleri . Kwaye namanzi epompo esiwaselayo anokuba nawo amanye awo.
Ngaba imizimba yethu iyayidinga ngokwenene i-nitrate?
Ewe, ii-nitrate kunye nee-nitrites ziyafuneka kwiinkqubo ezininzi ezibalulekileyo emizimbeni yethu. Enyanisweni, yi-85% kuphela yee-nitrate esizityayo ekutyeni kwethu ezivela kwimifuno .
Okwenzekayo ngaphakathi emizimbeni yethu kubaluleke kakhulu. Ii-nitrate esizisebenzisayo ziguqulwa zibe zii-nitrites ngumzimba. Ezi nitrites emva koko zijika zibe yenye yeziphumo ezimbini. Esinye sisiphumo esihle kakhulu kuthi, kwaye esinye sisiphumo esinobungozi kancinci.
Icala elihle: iNitric Oxide
Lo "ngumntu olungileyo" kwibali lethu. I-nitric oxide, imolekyuli eyenziwe nge-nitrite, ibalulekile kwimpilo yentliziyo yethu.
- Inceda ekunciphiseni uxinzelelo lwegazi .
- Iyandisa imithambo yegazi kwaye iphucula ukujikeleza kwegazi .
- Oku kuyenza ibe luncedo kakhulu ekukhuseleni izifo zentliziyo .
Yingakho ukutya okutyebileyo kwimifuno kuthiwa kulungile entliziyweni. Kuba imifuno ngokwendalo inika i-nitrates ezidingwa ngumzimba wethu ukuze sivelise i-nitric oxide.
Icala eliyingozi: iiNitrosamines
Lo "ngumntu ombi" kweli bali. Ityhefu ye-nitrate kunye ne-nitriteEyona nto ibangela ukuba ithathwe njengetyhefu kwaye iyingozi kungenxa yeekhompawundi ezibizwa ngokuba yi-nitrosamines. Ezi zi -carcinogens , oko kuthetha ukuba zizinto ezinokubangela umhlaza.
Yiyo loo nto i-World Health Organisation (WHO) ibhengeze ukuba inyama ezicutshungulweyo zibangela umhlaza . Kumaqondo obushushu aphezulu, ii-nitrites zinokusabela ngakumbi kwiiproteni ezikwinyama ukuze zenze ezi nitrosamines ziyingozi.
Inyaniso efihliweyo ngasemva kweleyibhile ethi "Akukho Nitrate"
Ngoku, xa usiya kwivenkile enkulu, mhlawumbi ukhe wabona iisoseji kunye nebhekoni zibhalwe izinto ezifana " ne-organic ", "akukho nitrates zongeziweyo", kunye "ne-nitrate-free". Abantu abaninzi bacinga ukuba ezi zikhuselekile ngokupheleleyo. Kodwa kukho imfihlo encinci apha ekufuneka siyazi.
Bafuna indlela yokugcina ezi mveliso zibizwa ngokuba "azina-nitrate". Ngenxa yoko, basebenzisa umgubo weseleri .
Cinga nje, i-celery yimifuno ene-nitrate eninzi ngokwemvelo. Ngoko ke okwenzekayo xa ufaka umgubo we-celery kuyafana noko kwenzekayo xa ufaka i-sodium nitrate eveliswe ngamakhemikhali. Oko kuthetha ukuba loo mveliso ikwanazo nee-nitrate. Nangona ingabizwa ngokuba "ayina-nitrate" kuba ayongezwanga ngamakhemikhali, ngokomthetho, isiphumo emzimbeni siyafana. Ezo nitrate zinokuguquka zibe yi-nitrosamines.
Eyona nto ibalulekileyo ekufuneka uyiqwalasele yile:
- Kukho imida esemthethweni kwii-nitrate ezongezwe ngamakhemikhali. Ii-arhente ezifana ne-FDA (i-Food and Drug Administration) zibeke ubuninzi obunokugcinwa kwimveliso.
- Kodwa ii-nitrate ezongezwe kwimithombo yendalo, njengomgubo weseleri, azilawulwa ngokungqongqo. Ezinye izifundo zibonise ukuba ezi mveliso "zendalo" zinokuqulatha ii-nitrate eziphindwe kalishumi kunezo zenziwe ngeendlela eziqhelekileyo.
| Uhlobo lwenyama elungisiweyo (Imveliso) | Umda ovunyelweyo ngokusemthethweni (ppm - iinxalenye ngesigidi) |
|---|---|
| Inyama yehagu | 120 ppm (0.012%) |
| Isoseji ecoliweyo | 156 ppm (0.0156%) |
| Iham okanye ipastrami ecociwe ngetyuwa | 200 ppm (0.02%) |
Ngoko ke, yintoni isigqibo sokugqibela? Ngaba i-sodium nitrate iyingozi ngokwenene?
Ngokusekelwe kulwazi lwangoku, akucaci kwangoko ukuba i-compound sodium nitrate ngokwayo iyingozi. Njengoko sibonile, yinto efunekayo emizimbeni yethu, ingakumbi kwimpilo yentliziyo.
Eyona nto ibangela ingxaki asizizo ii-nitrate ngokwazo, kodwa ngumthombo esifumana kuwo ezo nitrate.
Cinga ngale nto njengevithamini. Iivithamini zibalulekile emizimbeni yethu. Kodwa ukuba uzithatha kakhulu, zinokuba yityhefu. Kunjalo ke.
Eyona ndlela isempilweni yokufumana ii-nitrate kukutya imifuno, kungekhona inyama ecoliweyo.
kutheni kunjalo?
Kunye nee-nitrate, imifuno ikwanazo izondlo ezininzi, ezifana nee-antioxidants ezifana ne-vitamin C kunye ne-fiber. Ezi antioxidants zinokuthintela ii-nitrate ekubeni zenze ezo nitrosamines ziyingozi. Oku kuthetha ukuba sifumana icala elihle le-nitrate kwimifuno kuphela.
Kodwa inyama ezicutshungulwayo azinazo ezi zondlo zikhuselekileyo. Zikwanamanqanaba aphezulu etyuwa kunye namafutha angenampilo. Ngoko ke zinamathuba amaninzi okwenza ii-nitrosamines.
Ngoko ke, endaweni yokuba ukhathazeke ngee-nitrate, qaphela apho uzifumana khona. Akuyonto inzima ukutya inyama ecutshungulweyo ngamanye amaxesha, kodwa kulungile ukungazifaki njengenxalenye yokutya kwakho kwemihla ngemihla.
Umyalezo Wokuya Ekhaya
- I-sodium nitrate isetyenziselwa ukugcina inyama ecutshungulwayo, kodwa ikwanceda imizimba yethu ivelise i-nitric oxide.
- Ii-nitrate ziba yingozi kuphela xa ziguquka zibe yi-nitrosamines, ezibangela umhlaza. Oku kunokwenzeka kakhulu xa utya inyama ezicutshungulweyo.
- Iileyibhile "ezingenazo i-Nitrate" zihlala zinemithombo yendalo ye-nitrate, efana nomgubo weseleri. Ngamanye amaxesha ezi zinokuba namanqanaba aphezulu e-nitrate kuneemveliso eziqhelekileyo.
- Eyona ndlela ilungileyo nekhuselekileyo yokufumana ii-nitrate kukutya imifuno efana nesipinatshi kunye ne-beetroot. Ii-antioxidants ezikuyo zithintela ukwakheka kwee-nitrosamines.
- Yonwabela ukutya okufana nesoseji kunye nebhekoni ngamanye amaxesha, kodwa ungazifaki njengenxalenye yokutya kwakho kwemihla ngemihla. Gxila ekutyeni okunesondlo, ingakumbi imifuno kunye neziqhamo.
- Ukuba uneengxaki okanye amathandabuzo malunga nokutya kwakho okanye impilo yentliziyo, soloko uqhagamshelana nogqirha wakho wosapho ukuze akunike icebiso.
