Kaya muli ndi nkhawa zokhudzana ndi nkhanza za nyama kapena simukukonda kukoma kwa nyama, chisankho chokhala wodya zamasamba (kapena ngakhale wodya zamasamba pa sabata) chimamveka ngati chimenecho - chisankho. Koma kafukufuku watsopano wofalitsidwa mu Zolemba pa Molecular Biology akunena kuti mutha kukhala ndi mphamvu zambiri pazakudya zanu kuposa momwe mumaganizira. Ofufuzawa adapeza kusinthika kwa majini komwe kumawoneka kuti kwasintha mwa anthu omwe amakonda zakudya zamasamba pazaka mazana ambiri, kuphatikiza ku India, Africa, ndi madera ena a East Asia, onse omwe masiku ano ali ndi zakudya "zobiriwira". (Onani Zifukwa 12 Zakudya Zamasamba Ndilo Lingaliro Labwino.)

Kaixiong Ye waku yunivesite ya Cornell ndi anzake adayang'ana kuchuluka kwa allele (mawu oti kusinthika kwa ma genetic) omwe amalumikizidwa ndi zamasamba mwa anthu 234 ochokera ku India ndi anthu 311 ochokera ku US omwe anali okonda zamasamba. Adapeza kusinthaku mu 68% ya amwenye komanso 18% ya aku America. Izi zikupititsa patsogolo lingaliro loti ndi anthu omwe amakhala m'malo azikhalidwe omwe amapulumuka pachakudya chodyeramo chomeracho omwe amakhala ndi mwayi wonyamula zamasamba. Anthu aku America amadya pafupipafupi zambiri-kafukufuku wina wofalitsidwa mu BMJ Tsegulani adapeza kuti zopitilira 57 peresenti ya zakudya za anthu aku U.S. ndizopangidwa ndi zakudya "zopangidwa kwambiri". (Kodi muyenera kudana ndi zakudya zosinthidwa?)

Chochititsa chidwi n'chakuti allele yomweyi imalola anthu omwe ali nawo "kupanga bwino omega-3 ndi omega-6 fatty acids ndikuwasintha kukhala mankhwala ofunikira kuti ubongo uyambe kukula," adatero Ye. Omega-3 fatty acids ndi mafuta oteteza mtima omwe amapezeka mu nsomba monga nsomba zakutchire; Omega-6s amapezeka mu ng'ombe ndi nkhumba. Omega-3s osakwanira komanso omega-6s osakwanira amakukhazikitsani pachiwopsezo chachikulu chotupa kapena matenda amtima, chowopsa makamaka kwa osadya nyama. Ndipo chifukwa chakusowa kwa omega-3s ndi omega-6s m'zakudya zawo, zanenedwa kuti zamasamba zimakhala ndi vuto lokugaya bwino. Kafukufukuyu ndi umboni kuti izi mwina zidasinthika kuti izi zitheke kwa iwo.

Zotsatira za kafukufukuyu zimalimbikitsa lingaliro la zakudya zamunthu payekha, adatero Ye. "Titha kugwiritsa ntchito chidziwitso cha genomic kuyesa kukonza zakudya zathu kuti zigwirizane ndi ma genome athu," adatero m'mawu ake. Kupatula apo, palibe chakudya chamtundu umodzi. Mukufuna kukhazikitsa chizolowezi chanu pakudya nthawi zonse? Tsatani chakudya chanu ndikumvetsera thupi lanu. (Umu ndi Momwe Mungapangire Ntchito Yofalitsa Chakudya Kuti Ikuthandizireni.) Mimba yovutitsa itatha nthawi yamasana ndiye kuti ndi nthawi yoti muponye burger ndipo mwina mungasankhe kukulunga veggie nthawi ina, m'malo mwake.
