Kudya nyama ndikoopsa ku thanzi. Pakati pa mwezi wa August, mchitidwe wopopera tizilombo toyambitsa matenda pazanyama unavomerezedwa mwalamulo. Utsi wa kampani ya Baltimore umatchedwa Intralytix, womwe uli ndi mitundu isanu ndi umodzi ya ma virus opangidwa kuti aphe listeriosis. Makampani anyama safunikira kudziwitsa ogula zakudya zomwe zakonzedwa komanso zomwe sizinakonzedwe. Zaka makumi angapo zapitazo, tinaphunzira kuti mafuta opezeka mu nyama amawonjezera kuchuluka kwa cholesterol m'mwazi wa ogula. Ndipo izi zimatsogolera ku matenda a mtima. Choncho, madokotala anatilangiza kuchepetsa kudya nyama ndi kulemeretsa zakudya ndi masamba. Pa nthawi yomweyi, lingaliro la "carcinogens" linawonekera. Nyama yokazinga imayambitsa khansa. Mankhwala otchedwa heterocyclic amines amapanga pamwamba pa nyama, mu crispy kutumphuka. Ndi chifukwa cha kutumphuka kumeneku kuti chiwerengero cha khansa mwa odya nyama chikuwonjezeka. Nkhuku, monga momwe zimakhalira, imapanga ma carcinogens ambiri kuposa ng'ombe. Bwanji ngati muwiritsa nkhuku? Kafukufuku wasonyeza kuti mercury, heavy metals, ndi mankhwala osiyanasiyana ophera tizilombo ali ochuluka m’minyewa ya nyama. Ndikukumbukira momwe nsomba zidalengezedwa kuti ndizowopsa kwambiri: mabungwe aboma ndi boma adapereka machenjezo okhwima, nsomba ndizowopsa makamaka kwa ana ndi akazi azaka zakubadwa. Kenako anayamba kulankhula za tizilombo toyambitsa matenda m’nyama. Salmonella ndi Campylobacter amanenedwa kuti ndi omwe amachititsa masauzande ambiri chaka chilichonse. Chiwopsezo cha bakiteriya chinafika pamlingo winanso pamene E. coli inatsogolera ku imfa zambiri pakati pa odya ma hamburger. Olowa ndi ena oopsa nthawi zambiri amagunda nyama ya ng'ombe, nkhuku ndi nkhono. Ndipo mabungwe aboma akuwononga ndalama zokwana madola mamiliyoni ambiri pofuna kuthana ndi vutolo. Komanso - zoipa. Matenda a ng'ombe amisala anachokera ku Ulaya ndipo akhala akuwonedwa mwa apo ndi apo ku ng'ombe za ku North America. Sizinayambidwe ndi mafuta, ma carcinogens, kapena tizilombo toyambitsa matenda, koma ndi mtundu wapadera wa mapuloteni otchedwa prion. Akuluakulu aboma ndi mafakitale akuwononga ndalama zambiri poyesa, ndipo akatswiri amisala akuphunzira za ubale womwe ulipo pakati pa matenda amisala a ng'ombe ndi mitundu yosowa ya dementia. Pakadali pano, asayansi angazindikire kuti katsitsumzukwa ndi biringanya sizimayambitsa matenda a chiwewe komanso misala. Mapeyala samadwala chimfine, komanso chimfine cha sitiroberi kulibenso. Koma chimfine cha mbalame chinayamba kukhala mliri. Mbalame zimagwidwa ndi ma virus, monganso nyama zina. Nthawi zambiri sakhala owopsa kwa anthu. Koma anthu a m’dera lathu amakonda kwambiri mbalame—anthu aku America tsopano amadya nkhuku zoposa miliyoni imodzi pa ola limodzi—ndipo zimenezi zikutanthauza kuti nkhuku zambiri, akalulu, ndi mbalame zina zimaŵetedwa kuti zidye. Kachilombo ka H5N1 kakakhazikika m’famu la nkhuku, kamafalikira mofulumira.
Ndipo tsopano, pofuna kupha majeremusi ena amene amachokera m’matumbo a nyamayo ndi nthaka pa chidutswa cha nyama chokhala ndi mafuta ochuluka ndi mafuta a kolesterolini, anthu aganiza zopopera nyamayo ndi mavairasi. Nthawi yodzuka ndikununkhiza vuto. Mamiliyoni aku America tsopano alibe nyama. Akatero, cholesterol yawo idatsika. Mitsempha yawo yapamtima inatsegukanso. Kulemera kwawo kumachepa, ndipo mwayi wawo wopeza khansa umachepetsedwa ndi 40 peresenti. Zakudya zamasamba zopatsa thanzi zitha kutsitsimutsa dziko. Neil D. Barnard, MD, wofufuza zakudya komanso pulezidenti wa Komiti ya Madokotala a Mankhwala Oyenera.
