I-hormone yokukhula ingatholakala ngempela ngobisi lwezinkomo .
Ukukhula kweHormone kuLisi
Ngenkathi ezinye zazo ziyi-hormone yokukhula ye-bovine (rBST) evuselelwa kakhulu ye-bovine (rBST) enikezwa izinkomo ukuze ibasize ekwenzeni ubisi obengeziwe, ubisi bonke bezinkomo luqukethe uhlobo oluvela ngokwemvelo lwe-hormone yokukhula efanayo. Yiqiniso, yi-hormone yokukhula eyengeziwe eyenziwe ngabantu abathile.
Kubalulekile ukukhumbula ukuthi kungakhathaliseki ukuthi imvelo noma yokwenziwa, ama-hormone amaningi aphethwe yi-pasteurization. I-hormone yokukhula ye-bovine ephila ekusongeni futhi iphinde isinde ekugayeni, ayikwazi ukungena emathunjini ethu anemitholampilo yokwanda kwe-hormone yabantu.
Abanye abazali nabo bakhathazekile ngokukhula kwe-Insulin-1 (i-IGF-1), okwandiswa ezinkambeni ezitholakalayo zokwakheka kwe-bovine ekukhuleni kwe-bovine. Nakuba kungabhubhiswanga ngokudla okungajwayelekile, njenge-hormone yokukhula ye-bovine, i-IGF-1 ayitholi emathunjini ethu. Ngisho noma kunjalo, imizimba yethu ngokwemvelo ngokwemvelo yenza i-IGF-1 engaphezu kosuku ngalunye kunalokhu singaluthola ubisi esiyiphuzayo.
Ukukhathazeka NgamaHormone Okukhula Ngomsi
Nakuba kuthiwa ukuthi ama-hormone ekukhuleni ebisi ahlanganiswa nokukhulelwa kwasekuqaleni ( ukukhulelwa kokuqala ) ezinganeni kubonakala sengathi ukukhathazeka okuvamile kwabazali abathile, izifundo eziningi manje ziye zafakaza leyo mbono.
Ucwaningo manje lubhekisela ekukhuphukeni kokukhuluphala kwengane njengesizathu esithile sokuthi ezinye izingane ziqale ukukhulelwa eminyakeni engaphambili.
Kungani usho ama-hormone okukhula ebisi? Kungenzeka ukuthi kuyinto elula ukusola, njengoba ubisi oluvela ezinkampeni eziphathwe yi-rBST ezithengisa emakethe phakathi nawo-1990. Lokho kungekudala ngaphambi kokuthi ezinye izifundo zokuqala zibonise ukuthi ezinye izingane ziqala ukukhulelwa kancane kancane kunalokho ezazisebenzisa ngaphambili.
Inkinga eyodwa ngombono wokuthi i-hormone yokukhula akuyona i-hormone ye-steroid efana ne-estrogen. Kuyinto i-protein hormone eyabhujiswa kakhulu yi-pasteurization nokugaya. Ngisho nezingane ezithola izijovo zansuku zonke ze-hormone yokukhula yabantu ngesimo esifushane nezinye izimo zezokwelapha aziqali ukukhulelwa ekuqaleni.
Ngaphezu kokungabangeli ukukhulelwa kwasekuqaleni, ubisi oluvela ezinkomeni eziphathwa nge-rBST nazo azicatshangwa ukuthi zandisa ingozi yomuntu ngomdlavuza webele noma umdlavuza wesibeletho.
Nokho, ngaphezu kwezempilo yezingane nezingane, njengoba izifundo zingavumelani eziningi zalezi zingozi, abanye abantu bakhathazekile ngempilo yezinkomo eziphathwa nge-rBST. Isibonelo, lezi zinkomo zinengozi encane yokuthuthukisa i-mastitis, okumele iphathwe ngama-antibiotics. Nakuba lezi zinqamuzana zingapheli ebisi, ezihlolwe futhi zihlolwe, imithetho emisha yokuzithandela evela ku-FDA "yokuqeda ukusebenzisa imithi ethile yemithi yokukhiqiza ukudla okuthuthukisiwe" ingase ifake le nkinga ibe yibala.
Ngesikhathi umzamo wokunciphisa ukusetshenziswa kwama-antibiotic ukusiza ukunciphisa ukuthuthukiswa kwemithi yokulwa namagciwane manje igxile kuma-antibiotic athi "ayengezwa ekudleni kwezilwane noma emanzini okuphuza ezinkomo, izinkukhu, izinkukhu kanye nezinye izilwane ezikhiqiza ukudla ukuze zizuze isisindo ngokushesha noma sebenzisa ukudla okuncane ukuze uzuze isisindo, "zizobuyela ezinkabeni eziphethwe i-rBST ngokulandelayo?
Ukugwema amaHormoni ekukhuleni eMlonyeni
Noma ngabe ucabangani ngama-hormone okukhula ebisi, manje kulula ukuwagwema uma uthanda.
Nakuba kuvunyelwe ukusetshenziswa ngo-1994, kuye kwaba kuphela kusukela ngo-2008 kulandela izinkantolo ezivela ezinhlanganweni ezimbili zokuhweba zobisi zobunikazi ezihlukene (International Dairy Foods Ass'n v. Boggs) ukuthi ubisi lungabhalwa njenge-free hormone yokukhula. Ekuqaleni, i-FDA ayidingi i-labeling ekhethekile ebisi ekhanda ephathwa nge-rBST ngoba yathi ayinalo igunya lokufuna ilebula lokudla okunjalo kusukela ubisi oluvela ezinkomeni eziphathwe futhi ezingaphenduliwe ezifanayo.
Ngakho-ke abantu abafuna ukugwema ubisi emakhompini abaphathwa nge-synthetic growth hormone banga:
- Thenga ubisi olubizwa ngokuthi i- rBST-free , elula kakhulu, njengoba itholakala ezitolo eziningi zokudla, kufaka phakathi i-Costco, i-Kroger, i-Safeway, ne-Wal-mart, njll.
- Thenga ubisi oluphilayo
- Thenga ezinye ubisi ezakhiwe nge- vitamin D ne- calcium , njengobisi lwe-soy, ubisi lwe-almond, ubisi lwe-hemp, noma ubisi lwelayisi, njll.
Uma nje ugwema ubisi bese uhamba neminye imikhiqizo yobisi, kuhlanganise ushizi, i-yogurt, ne-ayisikhilimu, khumbula ukuthi ngaphandle uma nabo bebhalwe i-rBST, bangabe besenziwe ngobisi oluvela emfuyweni ephathwe nge-synthetic growth hormone. Kodwa-ke, njengobisi lwe-RBST, kulula ukuthola ezinye imikhiqizo yobisi e-rBST.
Ingabe Besebebeka Ukuvuthwa KwamaHormomu Emanzini?
Ingabe kufanele ugweme ubisi kusuka ezinkabeni ze-RBST?
Ngeshwa, njengoba ezinye izifundo ziphikisana nabanye ngemiphumela eyingozi ye-RBST ezinkanjeni, abalandeli bonke ukuthi izinkomo eziphathekayo ze-rBST zidinga izinsiza ezimbalwa zokukhiqiza inani elifanayo lobisi, kanti i-FDA "iphetha ukuthi ukusetshenziswa kwezinsana nezingane zobisi Imikhiqizo edlayo evela ezinkomeni eziphethwe yi-rbGH iphephile, "kungenzeka ukuthi isinqumo mayelana nokuthenga ubisi kusuka ezinkomeni eziphathwe nge-rBST sithathwe kuwe.
I-hype mayelana nama-hormone ekukhuleni ebisi kungenzeka ukuthi ayisususanga kuphela emashalofini esitolo kodwa kungenzeka ukuthi yayineminye imiphumela.
Bangaki abazali abaye bagwema ubisi lwezinkomo ngokuphelele ngenxa yokukhathazeka okungafanelekile mayelana nama-hormone okukhula ebisi?
Bangaki abashintshe kwezinye izindlela eziyingozi, njengobisi oluhlaza?
