Nyama imapha anthu ambiri kuposa momwe amaganizira poyamba

Pali zifukwa zambiri zosiya nyama. Nyama imakhala ndi zinthu zoopsa kwambiri zomwe zimayambitsa kufa ndi matenda ambiri. Kudya nyama nthawi zonse kumawonjezera chiopsezo cha imfa kuchokera kuzinthu zonse, kuphatikizapo matenda a mtima ndi khansa.

Izi zidakwaniritsidwa ndi asayansi chifukwa cha kafukufuku wa federal omwe adachita mothandizidwa ndi National Cancer Institute ndipo adalembedwa mu US Archives of Internal Medicine.

Kafukufukuyu adakhudza amuna ndi akazi oposa theka la milioni azaka zapakati pa 50 mpaka 71, ndipo adaphunzira zakudya zawo ndi zizolowezi zina zomwe zimakhudza thanzi lawo. Mkati mwa zaka 10, pakati pa 1995 ndi 2005, amuna 47 ndi akazi 976 anamwalira. Ofufuzawo adagawa anthu odziperekawo m'magulu 23. Zinthu zazikuluzikulu zonse zidaganiziridwa - kudya zipatso ndi ndiwo zamasamba zatsopano, kusuta, kuchita masewera olimbitsa thupi, kunenepa kwambiri, ndi zina zotero. Anthu omwe amadya nyama yambiri - pafupifupi 276 g ya nyama yofiira kapena yokonzedwa patsiku amafanizidwa ndi omwe amadya nyama yofiira pang'ono. - 5 g patsiku.

Azimayi amene amadya kwambiri nyama yofiira anali ndi chiopsezo chowonjezereka cha kufa ndi khansa ndi 20 peresenti ndipo 50 peresenti yowonjezera chiopsezo cha kufa ndi matenda a mtima ndi mitsempha, poyerekeza ndi amayi omwe amadya nyama yochepa. Amuna amene amadya nyama yambiri anali ndi chiopsezo chachikulu cha kufa ndi khansa ndi 22 peresenti ndi 27 peresenti ya chiopsezo cha kufa ndi matenda a mtima.

Phunziroli linaphatikizaponso deta ya nyama yoyera. Zinapezeka kuti kuwonjezeka kwa kudya nyama yoyera m'malo mwa nyama yofiira kunagwirizanitsidwa ndi kuchepa pang'ono kwa chiopsezo cha imfa. Komabe, kudya kwambiri nyama yoyera kumabweretsa chiopsezo chachikulu cha imfa.

Choncho, kutengera zomwe zachitika pa kafukufukuyu, 11 peresenti ya imfa za amuna ndi 16 peresenti ya imfa za amayi zikhoza kupewedwa ngati anthu atachepetsa kudya nyama yofiira. Nyama imakhala ndi mankhwala angapo oyambitsa khansa komanso mafuta osapatsa thanzi. Nkhani yabwino ndiyakuti boma la US tsopano likulangiza zakudya zochokera ku zomera zomwe zimayang'ana kwambiri zipatso, ndiwo zamasamba, ndi mbewu zonse. Nkhani yoyipa ndiyakuti imaperekanso thandizo lalikulu lazaulimi lomwe limapangitsa kuti mitengo ya nyama ikhale pansi komanso kulimbikitsa kudya nyama.

Ndondomeko yamitengo yazakudya zaboma imathandizira kukulitsa kuopsa kokhudzana ndi zizolowezi zoyipa monga kudya nyama. Nkhani ina yoipa ndi yakuti kafukufuku wa National Cancer Institute amangonena kuti "kuwonjezeka kwa chiopsezo cha imfa chifukwa cha kudya nyama." Tiyenera kudziwa kuti ngati kudya nyama kupha anthu ambiri, kungathe kudwalitsa anthu ambiri. Zakudya zomwe zimapha kapena kudwalitsa anthu siziyenera kutengedwa ngati chakudya.

Komabe, ogulitsa nyama amaganiza mosiyana. Amakhulupirira kuti kafukufuku wa sayansi ndi wosavomerezeka. Purezidenti wa American Meat Institute, James Hodges, adati: "Nyama ndi gawo la zakudya zopatsa thanzi, zopatsa thanzi, ndipo kafukufuku akuwonetsa kuti zimapereka chisangalalo komanso kukhuta, zomwe zingathandize kuchepetsa thupi. Kulemera bwino kwa thupi kumathandiza kukhala ndi thanzi labwino.”

Funso ndilofunika kuika moyo umodzi pachiswe kuti mukhale ndi kukhutitsidwa pang'ono ndi kukhuta, zomwe zingatheke mosavuta mwa kudya zakudya zopatsa thanzi - zipatso, masamba, mbewu, nyemba, mtedza ndi mbewu.

Deta yatsopano imatsimikizira kafukufuku wam'mbuyomu: kudya nyama kumawonjezera chiopsezo chokhala ndi khansa ya prostate ndi 40 peresenti. Posachedwapa makolo adaphunzira kuti ana awo ali ndi chiopsezo chowonjezeka cha 60% cha khansa ya m'magazi ngati adyetsedwa nyama monga ham, soseji ndi ma hamburger. Odya zamasamba amakhala ndi moyo wautali komanso wathanzi.

Posachedwapa, kafukufuku wachipatala wasonyeza kuti kudya zakudya zamasamba moyenera kungakhale chisankho chabwino. Izi zinasonyezedwa m’kafukufuku wa anthu ongodzipereka oposa 11. Kwa zaka 000, asayansi aku Oxford akhala akuphunzira momwe zakudya zamasamba zimakhudzira moyo, matenda amtima, khansa ndi matenda ena osiyanasiyana.

Zotsatira za kafukufukuyu zinadabwitsa anthu okonda zamasamba, koma osati mabwana a malonda a nyama: “Odya nyama ali ndi mwayi wowirikiza kawiri kufa ndi matenda a mtima, 60 peresenti ya kufa ndi khansa, ndipo 30 peresenti amafa ndi matenda ena. zoyambitsa.”  

Kuonjezera apo, chiwerengero cha kunenepa kwambiri, chomwe ndi chofunikira kuti chitukuko cha matenda ambiri, kuphatikizapo matenda a ndulu, matenda oopsa komanso matenda a shuga, ndizochepa kwambiri mwa omwe amatsatira zakudya zamasamba. Malinga ndi lipoti la University of Johns Hopkins lochokera pa maphunziro 20 osiyanasiyana ofalitsidwa ndi maphunziro a dziko lonse onena za kulemera ndi kadyedwe kake, anthu a ku America kudutsa misinkhu yonse, amuna kapena akazi ndi mafuko akukula. Ngati izi zipitilira, 75 peresenti ya akuluakulu aku US adzakhala onenepa kwambiri pofika 2015.

Tsopano yakhala pafupifupi chizolowezi kukhala onenepa kapena onenepa. Kale, oposa 80 peresenti ya amayi a ku America a zaka zapakati pa 40 ndi onenepa kwambiri, ndipo 50 peresenti ya iwo akugwera m'gulu la kunenepa kwambiri. Izi zimawapangitsa kukhala pachiwopsezo chachikulu cha matenda amtima, shuga ndi mitundu yosiyanasiyana ya khansa. Zakudya zopatsa thanzi zamasamba zitha kukhala yankho ku mliri wa kunenepa kwambiri ku United States ndi mayiko ena ambiri.  

Omwe amachepetsa kuchuluka kwa nyama m'zakudya zawo amakhalanso ndi mavuto ochepa a cholesterol. Bungwe la American National Institutes of Health linaphunzira anthu 50 odyetsera zamasamba ndipo anapeza kuti odya zamasamba amakhala ndi moyo wautali, ali ndi ziwopsezo zotsika kwambiri za matenda a mtima komanso amachepetsa kwambiri khansa kuposa anthu aku America odya nyama. Ndipo mu 000, Journal of the American Medical Association inanena kuti zakudya zamasamba zimatha kuteteza 1961-90% ya matenda a mtima.

Zimene timadya n’zofunika kwambiri pa thanzi lathu. Malinga ndi kunena kwa bungwe la American Cancer Society, pafupifupi 35 peresenti ya khansa zatsopano 900 zomwe zimapezeka chaka chilichonse ku United States zingapewedwe mwa kutsatira malangizo oyenera a kadyedwe. Wofufuza wina dzina lake Rollo Russell analemba m’zolemba zake ponena za chiyambi cha kansa kuti: “Ndinapeza kuti m’maiko XNUMX m’mene anthu ambiri amadya nyama, khumi ndi asanu ndi anai anali ndi chiŵerengero chachikulu cha kansa, ndipo limodzi lokha linali ndi chiŵerengero chochepa. Ndipo pa mayiko makumi atatu ndi asanu amene amadya nyama yochepa kapena osadya konse, palibe amene ali ndi chiŵerengero chachikulu cha khansa.”  

Kodi khansa ingataye malo ake m’chitaganya chamakono ngati ambiri atembenukira ku zakudya zopatsa thanzi zamasamba? Yankho ndi lakuti inde! Izi zikuwonetsedwa ndi malipoti awiri, imodzi kuchokera ku World Cancer Research Foundation ndi ina kuchokera ku Komiti Yokhudza Zachipatala za Chakudya ndi Chakudya ku UK. Iwo anaganiza kuti kudya zakudya zokhala ndi zomera zambiri, kuwonjezera pa kukhalabe ndi thupi labwino, kungalepheretse anthu pafupifupi 80 miliyoni padziko lonse kudwala khansa padziko lonse. Malipoti onsewa akutsindika kufunika kowonjezera kudya kwa tsiku ndi tsiku kwa ulusi wa zomera, zipatso ndi ndiwo zamasamba ndi kuchepetsa kudya nyama yofiira ndi yokonzedwa kuti ikhale yosachepera 90-XNUMX magalamu patsiku.

Ngati panopa mumadya nyama nthawi zonse ndipo mukufuna kusintha zakudya zamasamba, ngati simukudwala matenda a mtima, musataye zinthu zonse za nyama nthawi imodzi! Dongosolo la m'mimba silingagwirizane ndi njira ina yodyera tsiku limodzi. Yambani ndi kuchepetsa zakudya zomwe zimaphatikizapo nyama monga ng'ombe, nkhumba, mwanawankhosa, ndi mwanawankhosa, m'malo mwa nkhuku ndi nsomba. M'kupita kwa nthawi, mudzapeza kuti mudzatha kudya nkhuku ndi nsomba zochepa, popanda kuika maganizo pa thupi lanu chifukwa cha kusintha mofulumira kwambiri.

Zindikirani: Ngakhale uric acid zili nsomba, Turkey, ndi nkhuku ndi otsika kuposa nyama wofiira, choncho zochepa za katundu impso ndi ziwalo zina, mlingo wa kuwonongeka kwa mitsempha ndi m`mimba thirakiti kumeza coagulated. mapuloteni salinso osachepera kudya nyama wofiira. Nyama imabweretsa imfa.

Kafukufuku wasonyeza kuti anthu onse odya nyama amakhala ndi vuto lalikulu la matumbo a parasitic infestation. Izi sizosadabwitsa, chifukwa chakuti nyama yakufa (cadaver) ndi chandamale chokondedwa cha tizilombo tamitundu yonse. Mu 1996, kafukufuku amene dipatimenti ya zaulimi ya ku United States inachita anapeza kuti pafupifupi 80 peresenti ya ng’ombe ya padziko lonse inali ndi tizilombo toyambitsa matenda. Gwero lalikulu la matenda ndi ndowe. Kafukufuku yemwe adachitika ku yunivesite ya Arizona adapeza kuti mabakiteriya ambiri am'mimba amatha kupezeka m'sinki yakukhitchini kuposa m'chimbudzi. Choncho, n’kwabwino kudyera chakudya chanu pampando wa chimbudzi kusiyana ndi kukhitchini. Gwero la biohazard iyi mnyumba ndi nyama yomwe mumagula ku golosale wamba.

Tizilombo tating'onoting'ono ndi tizilombo tomwe timapezeka mu nyama timafooketsa chitetezo cha mthupi ndipo ndizomwe zimayambitsa matenda ambiri. Ndipotu, zakudya zambiri zakupha masiku ano zimagwirizanitsidwa ndi kudya nyama. Panthawi ya mliri ku Glasgow, 16 mwa anthu oposa 200 omwe anali ndi kachilomboka adamwalira chifukwa chodya nyama yowonongeka ndi E. coli. Kuphulika kwapawiri kwa matenda kumawonedwa ku Scotland ndi madera ena ambiri padziko lapansi. Anthu opitilira theka la miliyoni aku America, ambiri mwa iwo ndi ana, agwa ndi mabakiteriya osasinthika omwe amapezeka mu nyama. Tizilombo tating'onoting'ono tomwe timayambitsa matenda a impso mwa ana ku United States. Mfundo imeneyi yokha iyenera kulimbikitsa kholo lililonse laudindo kuti asatengere ana awo ku nyama.

Si majeremusi onse omwe amagwira ntchito mwachangu ngati E. coli. Zambiri mwa izi zimakhala ndi zotsatira za nthawi yayitali zomwe zimawonekera pambuyo pa zaka zambiri zakudya nyama. Boma ndi makampani opanga zakudya akuyesera kusokoneza chidwi cha anthu ku matenda a nyama powauza ogula kuti ndi vuto lawo kuti izi zichitike. Zikuwonekeratu kuti akufuna kupewa udindo wamilandu yayikulu ndikunyoza makampani anyama. Amaumirira kuti kuphulika kwa matenda owopsa a bakiteriya kumachitika chifukwa ogula sanaphike nyamayo nthawi yayitali.

Panopa anthu amaona kuti ndi mlandu kugulitsa chitumbuwa chosapsa. Ngakhale ngati simunachite “mlandu” umenewu, matenda aliwonse akhoza kumamatirani kwa inu ngati simusamba m’manja nthawi iliyonse mukagwira nkhuku yaiwisi kapena kulola nkhuku kukhudza tebulo lanu lakukhitchini kapena chakudya chanu chilichonse. Nyama yokhayo, malinga ndi zomwe akuluakulu aboma adanena, ilibe vuto lililonse ndipo imakwaniritsa zofunikira zachitetezo chovomerezedwa ndi boma, ndipo izi ndi zoona pokhapokha mutateteza manja anu ndi khitchini yanu.

Malingaliro abwinowa akunyalanyaza kufunika kothana ndi matenda okhudzana ndi nyama okwana 76 miliyoni pachaka pofuna kuteteza zofuna za boma ndi zanyama. Matenda akapezeka muzakudya zopangidwa ku China, ngakhale sanaphe aliyense, amachoka m'mashelufu am'golosale nthawi yomweyo. Komabe, pali maphunziro ambiri omwe amatsimikizira kuvulaza kudya nyama. Nyama imapha anthu mamiliyoni ambiri chaka chilichonse, koma ikupitilizabe kugulitsidwa m'masitolo onse ogulitsa.

Tizilombo tatsopano tomwe timapezeka mu nyama timapha kwambiri. Kuti mupeze matenda a salmonellosis, muyenera kudya pafupifupi miliyoni imodzi mwa tizilombo toyambitsa matenda. Koma kuti mutengere limodzi mwa mitundu yatsopano ya ma virus kapena mabakiteriya, muyenera kumeza asanu okha. Mwa kuyankhula kwina, kamphindi kakang'ono ka hamburger yaiwisi kapena dontho la madzi ake pa mbale yanu ndikwanira kukuphani. Asayansi tsopano apeza tizilombo toyambitsa matenda toposa XNUMX topezeka m’zakudya tokhala ndi zotulukapo zakupha zoterozo. CDC imavomereza kuti ndi omwe amachititsa matenda ambiri okhudzana ndi zakudya komanso imfa.

Nthawi zambiri za kuipitsidwa kwa nyama kumachitika chifukwa chodyetsa ziweto zomwe sizikhala zachilengedwe. Panopa ng’ombe zimadyetsedwa chimanga, zomwe sizingagayike, koma izi zimanenepetsa mwachangu. Ng'ombe zimakakamizidwanso kudya chakudya chokhala ndi ndowe za nkhuku. Mamiliyoni a mapaundi a manyowa a nkhuku (ndowe, nthenga ndi zonse) amachotsedwa pansi pa nyumba zoweta nkhuku ndi kuwapanga kukhala chakudya cha ziweto. Ogulitsa ziweto amawona kuti ndi "gwero labwino kwambiri la mapuloteni".  

Zosakaniza zina mu chakudya cha ng'ombe ndi mitembo ya nyama, nkhuku zakufa, nkhumba ndi akavalo. Malinga ndi malingaliro amakampani, zingakhale zodula komanso zosatheka kudyetsa ziweto ndi chakudya chachilengedwe komanso chathanzi. Ndani amene amasamala za nyama yomwe imapangidwa malinga ngati ikuwoneka ngati nyama?

Kuphatikizidwa ndi Mlingo waukulu wa mahomoni akukula, chakudya cha chimanga ndi zakudya zapadera zimafupikitsa nthawi yomwe ng'ombe imanenepa kuti igulidwe pamsika, nthawi yonenepa yodziwika bwino ndi zaka 4-5, nthawi yonenepa kwambiri ndi miyezi 16. N’zoona kuti zakudya zosakhala zachibadwa zimadwalitsa ng’ombe. Mofanana ndi anthu amene amawadya, amadwala kutentha kwa mtima, matenda a chiwindi, zilonda zam’mimba, kutsegula m’mimba, chibayo, ndi matenda ena. Kuti ng'ombe zikhale ndi moyo mpaka zitaphedwa pakatha miyezi 16, ng'ombe zimapatsidwa mankhwala opha tizilombo toyambitsa matenda. Panthaŵi imodzimodziyo, tizilombo toyambitsa matenda timene timalimbana ndi kuukira kwakukulu kwa biochemical kwa maantibayotiki tikupeza njira zotha kugonjetsedwa ndi mankhwalawa mwa kusintha kukhala mitundu yatsopano yosamva. Zitha kugulidwa pamodzi ndi nyama ku golosale kwanuko, ndipo pakapita nthawi zidzakhala pa mbale yanu, pokhapokha ngati ndinu wodya zamasamba.
