Wolemba nkhani za sayansi m'nyuzipepala yaku America The Washington Post adasanthula zinthu zosiyanasiyana ndikuwona zomwe zikuyenera kugulidwa pokhapokha ngati "organic" zinthu, ndipo ndi ziti zomwe sizimafunikira kwambiri pakufunika kotere. Chisamaliro chapadera mu lipoti chinaperekedwa ku mkaka.
Ndi mkaka uti umene uli ndi thanzi? Kodi mkaka wa m'mafakitale uli ndi maantibayotiki ndi ma hormonal supplements? Kodi ndizotetezeka kwa ana? Mafunso awa ndi ena ayankhidwa ndi phunziroli.
Zinapezeka kuti poyerekeza ndi mkaka wamba (womwe umapezeka m'mafakitale ndikugulitsidwa m'masitolo ambiri mumzinda), mkaka wapafamu uli ndi mafuta ambiri omega-3-unsaturated mafuta acids - komanso, udzu watsopano umadya kwambiri ng'ombe. chaka, ambiri a iwo . Njira zina zopatsa thanzi za mkaka waulimi/zamalonda zaphunziridwa koma zikuwoneka kuti ndizosavomerezeka pazofufuza.
Mlingo wa kuipitsidwa ndi maantibayotiki mu mkaka wa famu ndi mafakitale ndi wofanana - zero: mwalamulo, mtsuko uliwonse wa mkaka umayenera kutsimikiziridwa ndi katswiri, ngati pali kusiyana, mankhwalawa amalembedwa (ndipo nthawi zambiri amatsanulidwa) . Ng'ombe zaulimi sizimapatsidwa maantibayotiki - ndipo ng'ombe za m'mafakitale amaperekedwa, koma panthawi ya matenda (chifukwa chachipatala) - ndipo mpaka kuchira kwathunthu ndipo mankhwalawa amathetsedwa, mkaka wa ng'ombezi sugulitsidwa.
Zakudya zonse zamkaka - zaulimi ndi mafakitale - zili ndi "zochepa kwambiri" (malinga ndi deta yovomerezeka ya boma - ku United States) kuchuluka kwa poizoni wa DDE - "moni" kuyambira kale, pamene m'mayiko ambiri padziko lapansi anayamba kugwiritsa ntchito mankhwala osokoneza bongo. mankhwala oopsa DDT mopanda chilungamo (kenako anazindikira izo, koma izo zinali mochedwa - izo kale pansi). Malinga ndi asayansi, zomwe zili mu DDE mu dothi laulimi padziko lonse lapansi zidzachepetsedwa kukhala zosafunikira pakadutsa zaka 30-50.
Nthawi zina mkaka umabwera pamsika umene sunapangidwe bwino (cholakwika cha pasteurization) - koma palibe deta yomwe mkaka - mafakitale kapena famu - izi zimachitika kawirikawiri, ayi - mkaka uliwonse wochokera ku gwero lililonse uyenera kubweretsedwa ku chithupsa. Chifukwa chake chinthu ichi "chimayanjanitsa" mkaka waulimi ndi mkaka wa mafakitale.
Koma pankhani ya mahomoni - pali kusiyana kwakukulu! Ng'ombe zaulimi sizibayidwa ndi mankhwala a mahomoni - ndipo ng'ombe za "mafakitale" zilibe mwayi, zimabayidwa ndi hormone ya kukula kwa bovine (bovin-stomatotropin - yofupikitsidwa monga BST kapena zosiyana zake - recombinant bovin-stomatotropin, rBST).
Kodi jakisoni "othandiza" bwanji kwa ng'ombe ndi mutu wa phunziro lapadera, ndipo si mahomoni omwe ali owopsa kwa anthu (chifukwa, mwachidziwitso, ayenera kufa panthawi ya pasteurization kapena, nthawi zambiri, mwamakani. chilengedwe cha m'mimba mwa munthu), koma chigawo chake, chomwe chimatchedwa "insulin-like growth factor-1" (IGF-I). Kafukufuku wina amagwirizanitsa chinthu ichi ndi ukalamba ndi kukula kwa maselo a khansa m'thupi - ena samavomereza mfundo yotereyi. Malingana ndi mabungwe ovomerezeka ovomerezeka, mlingo wa IGF-1 mu mkaka wogula sitolo sudutsa chizolowezi chovomerezeka (kuphatikizapo kumwa ndi ana) - koma apa, ndithudi, aliyense ali ndi ufulu wodzipangira yekha.
