I-hormone yokukhula ingafumaneka ngokwenene kubisi lweenkomo .
Ukukhula kweHormone kwiLisi
Nangona ezinye zazo ziyi-hormone yokukhula ye-bovine ye-bovine (rBST) enokwenziwa komzimba ekuncedeni iinkomo ukubanceda benze ubisi obanzi, ubisi bonke beenkomo luqulethe uhlobo lwendalo oluqhelekileyo lwe-hormone yokukhula. Ngokuqinisekileyo, yi-hormone yokukhula eyongeziweyo eyenziwa ngabantu abathile malunga nayo.
Kubalulekile ukugcina engqondweni ukuba nokuba yendalo okanye yokwenziwa komzimba, uninzi lwa ma hormone lubonakaliswe ngumbutho. I-hormone yokukhula ye-Bovine eqhubekayo yokutya kunye nokuhlala isitya, ayikwazi ukuxhamla ngamathumbu ethu anokufumana i-hormone yokukhula kwabantu.
Abanye abazali banenkxalabo malunga nokukhula kwe-Insulin-1 (IGF-1), enyuka kwiinkomo ezitholayo i-hormone yokukhula ye-bovine. Nangona ingatshatyalaliswa ngokutya okuqhelekileyo, njenge-hormone yokukhula kwe-bovine, i-IGF-1 ayifakwe kumathumbu. Nangona ukuba kunjalo, imizimba yethu ngokwemvelo yenza i-IGF-1 yosuku ngalunye kunokuba sinokuyifumana ubisi esiphuzayo.
Ixhala Ngezolimo zeHormone kwiLisi
Nangona ama-hormone okukhula ebisi adibaniswa nobuntwaba bokuqala ( ubuntwabungqina obusasazekayo) kubantwana kubonakala kubangele ukukhathazeka okuqhelekileyo kwabazali abathile, uphando olutsha luye lwaqulunqa loo mbono.
Uphando ngoku lubonisa ukunyuka kokunyamezela komntwana njengokuba kunokwenzeka isizathu sokuba abantwana abathile baqale ukutshatyalaliswa kwiminyaka engaphambili.
Kutheni i-hormone yokukhula ebomini ilahla? Kungenzeka kube lula ukusola, njengoko ubisi obuvela kwiinkomo eziphathwe yi-rBST zithatha i-market kwiminyaka-1990. Kwakukufutshane ngaphambi kokuba ezinye zezifundo zokuqala zibonise ukuba abanye abantwana baqalisa ukutshatyalaliswa kungekudala kunokuba babedla.
Enye ingxaki kunye nenkolelo kukuba i-hormone yokukhula ayikho i-hormone ye-steroid njenge-estrogen. I-protein hormone echithwa kakhulu yi-pasteurization kunye nokutya. Nangona abantwana abafumana iintsholongwane zemihla ngemihla ye-hormone yokukhula komntu ngesigxina esifutshane kunye nezinye izimo zonyango aziqali ukuqala.
Ukongezelela ukuba kungabangeli ubusuku bokuqala, ubisi oluvela kwiinkomo eziphathwe nge-RBST azicatshangwanga ukuba zenze umngcipheko womdlavuza wombele okanye umhlaza wesibeletho.
Ngaphandle kwempilo yabantwana kunye nabantwana, nangona iinjongo zichasene ezininzi zezo mngcipheko, abanye abantu bakhathazeke ngempilo yeenkomo eziphathwe nge-RBST. Ngokomzekelo, ezi nkomo zinomngcipheko omncinci wokwenza i-mastitis, ekufuneka iphathwe ngamayeza. Nangona ezi antibiotics zingapheli kubisi, ezihlolwe kwaye zavavanywa, imithetho emitsha yokuzithandela evela kwi-FDA "ukuqhelisa ukusetyenziswa kwemithi ethile yokulwa nemveliso yokutya" ingabangela ukuba lo mbandela ube ngumbonakalo.
Ngelixa umgudu wokunciphisa ukusebenzisa i-antibiotics ukunceda ukunciphisa ukuphuhliswa kwe-antibiotic resisting now kugxile kwii-antibiotiki "ezongeziweyo kwisondlo sezilwanyana okanye ukusela amanzi ezinkomo, iinkukhu, iinkuku kunye nezinye izilwanyana ezivelisa ukutya ukuze zibancede isisindo ngokukhawuleza okanye sisebenzise ukutya okuncinci ukufumana ubunzima, "ngaba baya kubuyela kwiinkomo zonyango ze-RBST ezilandelayo?
Ukugwema iiHormone zoKhula eMlonyeni
Nantoni na ocinga ngayo ngama-hormone ekukhuleni ebisi, ngoku kulula ukuwaphepha ukuba ufuna.
Nangona ivunyiwe ukuba isebenziswe ngo-1994, isuka kuphela ukususela ngo-2008 emva kwezigwebo ezivela kwimibutho yokurhweba yobisi bezolimo ezimbini (i-International Dairy Foods Ass'n v. Boggs) ukuba ubisi lingabhalwa njenge-free hormone yokukhula. Ekuqaleni, i-FDA ayifuni ilayibhile ekhethekileyo kubisi ukusuka kwinkomo ephathwe ngayo ne-RBST kuba bebatsho ukuba babengenalo igunya lokufuna iileyile yokutya kuba ubisi oluvela kwiinkomo eziphathweyo kwaye ezingakhange ziphathwe zizinto ezifanayo.
Ngoko abantu abafuna ukunqanda ubisi kwiinkomo eziphathekayo nge-synthetic growth hormone banga:
- Thenga ubisi obhalwe ngokuba yi- rBST-free , elula, njengoko ikhona kwiindawo ezininzi zokutya zokutya, kuquka ne-Costco, iKroger, Safeway, kunye ne-Wal-mart njl.
- Thenga ubisi obunjani
- Thenga enye yobisi eqiniswe nge- vitamin D kunye ne- calcium , njengobisi lwe-soy, ubisi lwe-almond, ubisi lwe-hemp, okanye ubisi lwelayisi, njl njl.
Ukuba uphephe ubisi kwaye uhambe nezinye iimveliso zobisi, kuquka i-cheese, i-yogurt kunye ne-ayisikrimu, gcinani engqondweni ukuba ngaphandle kokuba nabo babhalwe nge-rBST-free, ngoko bebenokwenziwa ngobisi kwiinkomo eziphathwe nge-hormone yokukhula. Njengobisi be-RBST-free, kulula ukufumana ezinye iimveliso zobisi ezingenaso i-RBST.
Ngaba Basesenza Ukunyuka kwamaHormone eMlonyeni?
Ngaba kufuneka ugweme ubisi kwiinkomo zeRBST?
Ngelishwa, njengokuba ezinye izifundo ziphikisana nabanye ngemiphumo emibi ye-RBST kwiinkomo, abaxhasayo yonke into yokuba izilwanyana eziphathekayo ze-RBST zifuna iimithombo ezimbalwa zokuvelisa inani elifanayo lobisi, kwaye i-FDA "igqiba ukuba ukusetyenziswa ngabantwana kunye nabantwana bokubisi kunye Iimveliso ezidliwayo ezivela kwiinkomo eziphathwe nge-RBGH zikhuselekile, "isigqibo malunga nokuthenga ubisi kwiinkomo eziphathwe nge-rBST kungenzeka ukuba sithathwe kuwe.
Ingqungquthela malunga ne-hormone yokukhula ebisi kungenzeka ukuba ayisususanga kuphela kwiisitokethi zokugcina kodwa ingaba neminye imiphumo.
Bangaphi abazali abaye banqanda ubisi lweenkomo ngokupheleleyo ngenxa yokukhathazeka okungenakufaneleka malunga ne-hormone yokukhula ebisi?
Bangaphi baye batshintshela kwiindlela ezingezinhle, ezifana nobisi oluhlaza?
