Umlobi wezindaba zesayensi wephephandaba laseMelika iWashington Post uhlaziye imikhiqizo ehlukene futhi wathola ukuthi yimiphi okufanele ithengwe kuphela ngohlobo lwemikhiqizo “ephilayo,” nokuthi yimiphi engadingi kakhulu kuleso sidingo. Ukunakwa okukhulu embikweni kwanikezwa ubisi.
Iluphi ubisi olunempilo? Ingabe ubisi lwezimboni luqukethe ama-antibiotics kanye nama-hormone supplements? Ingabe iphephile ezinganeni? Le mibuzo kanye neminye iphendulwa yilolu cwaningo.
Kuvele ukuthi uma kuqhathaniswa nobisi olujwayelekile (olutholwe epulazini lezimboni futhi oluthengiswa ochungechungeni lwezitolo edolobheni), ubisi lwasepulazini lucebile ngama-acids anempilo e-omega-3-unsaturated fatty - ngaphezu kwalokho, lapho inkomo idla utshani obusha ngesikhathi. unyaka, baningi . Ezinye izindlela zokudla okunomsoco zobisi lwasepulazini/lwezentengiselwano zihlolisisiwe kodwa zibonakala zingenamsebenzi kudatha yocwaningo.
Izinga lokungcola ngama-antibiotics obisini lwasepulazini nasezimbonini liyafana - zero: ngokomthetho, ujeke ngamunye wobisi ungaphansi kokuqinisekiswa okuphoqelekile nguchwepheshe, uma kukhona ukungafani, umkhiqizo uyabhalwa (futhi ngokuvamile uthululwa) . Izinkomo zasepulazini azinikezwa ama-antibiotics - futhi izinkomo emapulazini ezimboni zinikezwa, kodwa kuphela ngesikhathi sokugula (ngenxa yezizathu zezokwelapha) - futhi kuze kube yilapho ukululama okuphelele futhi umuthi uyekwa, ubisi oluvela kulezi zinkomo aluthengiswa.
Yonke imikhiqizo yobisi - ipulazi kanye nezimboni - iqukethe "incane kakhulu" (ngokolwazi olusemthethweni lukahulumeni - e-United States) inani le-DDE toxin - "sawubona" kusukela esikhathini esidlule, lapho emazweni amaningi omhlaba baqala ukusebenzisa ikhemikhali eyingozi i-DDT ngokungafanele (babe sebeyibona, kodwa kwase kwephuze kakhulu - isivele iphansi). Ngokusho kososayensi, okuqukethwe kwe-DDE emhlabathini wezolimo emhlabeni wonke kuzoncishiswa kungabi nalutho kuphela eminyakeni engama-30-50.
Kwesinye isikhathi ubisi lufika emakethe olungakafakwanga kahle i-pasteurization (iphutha le-pasteurization) - kodwa akukho datha yokuthi ubisi lwezimboni noma ipulazi - lokhu kwenzeka kaningi, cha - noma yiluphi ubisi oluvela kunoma yimuphi umthombo kufanele lubilise kuqala. Ngakho-ke lesi sici siphinde "sivumelanise" ubisi lwepulazi nobisi lwezimboni.
Kodwa uma kuziwa kuma-hormone - kukhona umehluko omkhulu! Izinkomo zasepulazini azijovwe ngemithi yamahomoni - futhi izinkomo "zezimboni" azinayo inhlanhla kangako, zijovwa nge-hormone yokukhula yezinkomo (i-bovin-stomatotropin - efushanisiwe njenge-BST noma okuhlukile kwayo - i-recombinant bovin-stomatotropin, rBST).
Ukuthi imijovo enjalo “iwusizo” kangakanani enkomeni kuyisihloko socwaningo oluhlukile, futhi akuyona ngisho i-hormone ngokwayo eyingozi kubantu (ngoba, ngokombono, kufanele ife ngesikhathi sokuhluma noma, ezimweni ezimbi kakhulu, ku-aggressive. indawo yesisu somuntu), kodwa ingxenye yayo, ebizwa ngokuthi “insulin-like growth factor-1” (IGF-I). Ezinye izifundo zixhumanisa le nto nokuguga kanye nokukhula kwamangqamuzana omdlavuza emzimbeni - ezinye azisisekeli isiphetho esinjalo. Ngokusho kwezinhlangano eziqinisekisayo ezisemthethweni, izinga lokuqukethwe kwe-IGF-1 obisini oluthengwe esitolo alidluli inkambiso evumelekile (kuhlanganise nokusetshenziswa yizingane) - kodwa lapha, yiqiniso, wonke umuntu ukhululekile ukwenza iziphetho zakhe.
