Kwabaningi bethu, ukudla imifino eseleyo ngeke kubangele izinkinga uma nje kungabonakali futhi kuhlaziywa kahle, okungahambisani neze ne-nitrate.
Kunezikhathi ezimbili lapho abantu kufanele baqaphele nge-nitrate. Enye yalezi zikhathi iphakathi nezinyanga ezine zokuqala zokuphila - kodwa akunakwenzeka ukuthi izinsana ezincane ezihambayo zidla zisala noma yini.
Uma izinsana zivezwe ngokweqile kwe-nitrate, kuyoba ngamanzi asemzimbeni angase asetshenziselwe ukwenza ifomula yawo.
Isikhathi sesibili sokucabanga nge-nitrate ngesikhatsi sekugcina emasontweni 8 kuya ku-10 ekukhulelwa. Kodwa futhi, lokhu kubhekisela emanzini okuphuza abonakele ngamazinga aphakeme kakhulu e-nitrate - hhayi inani elivame ukutholakala emifino .
Lindela - Awuzange Uyazi Imifino YineziNitrate, Ingabe Wena?
Yebo, bayakwenza. Abanye kunabanye. Ngokusho kwe-US Centers for Disease Control and Prevention, i-cauliflower, isipinashi, imifino ye-collard, i-broccoli, i-beet, nemifino yempande iqukethe ama-nitrate amaningi kunezinye imifino.
Futhi, uyazi ngani? Emalini etholakala ekudleni okujwayelekile, i-nitrate ingahle ibe kuhle kuwe. Ngivumele ngibuyele kancane futhi ngikhulume nge-nitrate, ukuthi kungani besethusa nokuthi kungani kungase kungacatshangwa.
Ama-nitrate atholakala ngokwemvelo enhlabathini nasemanzini. Zakhiwa lapho ama-microorganisms eguqula izidakamizwa eziphilayo zibe yi-ammonia, ephendula nge-oksijini ukwenza i-nitrate ne-nitrite.
Yini Engama-Nitrate Embi?
Ama-nitrate atholakale kumanyolo, amanye ama-rodenticides kanye nokuthuthwa komuntu kanye nesilwane ukuze amanzi asemaphandleni angcoliswe emanzini aseduze asuka kumhlabathi ovuthiwe, amanzi angcolile kamasipala noma ama industrial, ama-landfills, ama-feedlots noma izinhlelo ze-septic.
Yebo, lokho kuyingozi njengoba kuzwakala.
I-standard federal yamazinga e-nitrate emanzini okuphuza ama-milligram ayi-10 ilitha lamanzi. Uma unomthombo, futhi une-nitrate engaphezu kwalokho, ungase udingeke wenze ezinye izinyathelo ezidlulele ukuze ukwazi ukusebenzisa lawo manzi. Kuhilela izinhlelo zokuhlunga kanye namathangi amakhulu kusendlini yakho.
Manje iningi lethu akudingeki libhekane nemithombo yamanzi yasemaphandleni kanti ngisho nabantu abanemithombo evamile akudingeki bakhathazeke nge-nitrate. Ngakho kuphi okunye okutholakele khona?
I-nitrate ye-sodium ingumlondolozo wokudla okuvame ukusetshenziselwa ukuphulukisa inyama ukuze uwuthole ekudleni okunjenge-bacon, ham, kanye nesoseji.
Nakhu lapho kuthola khona inkimbinkimbi.
Ucwaningo olunzulu lokucwaninga lubonisa ukuthi abantu abadla amanani amaningi kakhulu asetshenziselwa ukudla bavame ukuba nezingozi ezihlukahlukene zezifo ezihlukahlukene njengezifo zenhliziyo nezinye izinhlobo zomdlavuza. Ngakho impendulo yemvelo kwakuwukukhomba umunwe ku-nitrate enyameni esetshenzisiwe.
Kodwa, inyama esetshenzisiwe nayo iphezulu ngamakholori, elayishwa ngamafutha agcwele futhi i-sodium. Ngaphezu kwalokho, abantu abadla amaningi amaningi asetshenzisiwe bavame ukudla izithelo nemifino embalwa, thola ama-fiber angaphansi, nabathengi amakholori amaningi, bathuke ngaphezulu, baphuze ngaphezulu, futhi baphuze kancane.
Konke kukho konke lokho, inhlanganisela embi kakhulu.
Futhi mhlawumbe ukusola i-nitrate yayihamba kancane kancane. Kungenzeka ngenxa yanoma iyiphi noma zonke ezinye izici.
Kunoma yikuphi, uma nje i-nitrate ihambisana ne-vitamin C (ascorbate noma i-ascorbic acid) akudingeki ukhathazeke ngakho ukwenza izinto ezingekho empilo ezingakulimaza. Esikhathini esiningi lapho ubona i-nitrate ohlwini lwakho lwesithako, uzobona futhi i-vitamin C.
Yiziphi Nitrate Ezinhle?
Imifino ekhula enhlabathini izoba ne-nitrate. Eqinisweni, cishe amaphesenti angama-85 ezithambile zakho zansuku zonke - ama-milligram angu-20 kuya kwangu-25 ngosuku - zivela emifino. Futhi imifino ikuhle kuwe.
Uma umuntu ekutshela ukuthi imifino ikubi ngenxa ye-nitrate noma yimuphi omunye isizathu, kufanele ugijime kubo. Ngokushesha.
Abanye ososayensi bathi lokhu yingxenye yezizathu zokuhle kwemifino kungenzeka empeleni kungenxa yalezi nitrate. Ngaphandle kokuba uthole ubuchwepheshe obuningi, kungenzeka ukuthi i-nitrate inhle emithanjeni yakho yegazi kanye nokusiza ukunciphisa ukucindezelwa kwegazi futhi ugcine amapulethi egazini lakho ekugodleni kakhulu noma endaweni engafanele.
Umqondo wokuthi i-nitrate ingaba kuhle kuwe usaqhubeka esiteji sokuqala. Kodwa ngubani okhathalelayo ngempela - sesivele sazi ukuthi imifino ikuhle kuwe. Ngakho badle okuningi.
Kuthiwani ngokuvuselela imifino? Uma ubuyisa kabusha amanzi, uzogxilisa inani le-nitrate njengoba amanzi ekhuphuka. Mhlawumbe abantu besaba ukuthi ukuphuza imifino kuyinto efanayo. Into ewukuthi, uma uvuselela imifino yakho kuze kube yilapho esomile, yanyuka futhi igxile ekubeni yindawo ebi, ngingabazi ukuthi ngabe uyodla noma kunjalo.
Yidla imifino yakho . Londoloza okusele. Zishise futhi uzidle. Uzoba kuhle.
