Mwinamwake mukudziwa machenjezo a akatswiri a zakudya za kudya nyama yofiira kwambiri. Izi zikuphatikiza ng'ombe, mwanawankhosa, nkhumba, ndi mbuzi.

Kuchita izi kumawonjezera chiopsezo chanu pazinthu zingapo zanthawi yayitali, kuphatikiza zovuta zamtima, koma kafukufuku wina amafunikira pamutuwu.

Nanga bwanji zonena kuti nyama yofiira imayambitsa khansa? Akatswiri akuyang'anabe nkhaniyi, koma apeza zina zomwe zingagwirizane.

Kusiyanitsa pakati pa nyama yofiira yosakonzedwa ndi kukonzedwa

Musanalowe mu kafukufuku wozungulira ulalo pakati pa nyama yofiira ndi khansa, ndikofunikira kumvetsetsa mitundu yosiyanasiyana ya nyama yofiira.

Zosasinthidwa

Zakudya zofiira zosasinthidwa ndizomwe sizinasinthidwe kapena kusinthidwa. Zitsanzo ndi izi:

• nyama yang'ombe
• Zakudya za nkhumba
• ziboda zamphongo
• Zakudya zamphongo

Payokha, nyama yofiira yosatulutsidwa imatha kukhala yopatsa thanzi. Nthawi zambiri imakhala ndi mapuloteni, mavitamini, michere, ndi zinthu zina zofunika.

Nyama yofiira imataya zina zamtengo wapatali zikamakonzedwa.

Kukonzedwa

Nyama yosakidwa imatanthawuza nyama yomwe yasinthidwa mwanjira inayake, nthawi zambiri pakulawa, kapangidwe, kapena mashelufu. Izi zitha kuchitika ndikuthira mchere, kuchiritsa, kapena kusuta nyama.

Zitsanzo za nyama zofiira zopangidwa ndi izi:

• agalu otentha
• pepperoni ndi salami
• nyama yankhumba ndi nyama
• Zakudya zamasana
• soseji
• alireza
• wosasamala
• nyama zamzitini

Poyerekeza ndi nyama yofiira yosasinthidwa, nyama yofiira yosinthidwa nthawi zambiri imakhala yocheperako zakudya zopatsa thanzi komanso yamchere komanso mafuta.

Akatswiri amati nyama yofiira ndi yomwe imayambitsa khansa ikamadya kwambiri. Pali kulumikizana kwamphamvu pakati pa nyama zomwe zasinthidwa ndi chiopsezo cha khansa.

Akatswiri amaganiza kuti nyama yophika ndi khansa. Izi zikutanthauza kuti tsopano amadziwika kuti amachititsa khansa.

Zomwe kafukufukuyu wanena

Kwa zaka zambiri, kafukufuku wochuluka adayang'ana za thanzi la kudya nyama yofiira yosakonzedwa ndi yosinthidwa.

Pakadali pano, zotsatirazi zasakanikirana, koma pali umboni wina woti kudya nyama yofiira yambiri kumatha kukulitsa chiopsezo cha khansa zina.

Njira ya IARC

International Agency for Research on Cancer (IARC) ndi gawo la World Health Organisation. Amapangidwa ndi akatswiri apadziko lonse lapansi omwe amagwira ntchito yosanja ma carcinogen (othandizira khansa).

Pakakhala umboni wochuluka wosonyeza kuti china chake chingayambitse khansa, mamembala a IARC amakhala masiku angapo akuwunikanso maphunziro asayansi pazomwe zingachitike chifukwa cha khansa.

Amaganizira zinthu zingapo kuchokera paumboniwo, kuphatikiza momwe nyama zimayankhira ndi khansa, momwe anthu amayankhira, komanso momwe khansa ingayambire ikadzapezeka.

Gawo la njirayi limaphatikizapo kugawa zomwe zingayambitse khansa potengera zomwe zingayambitse khansa mwa anthu.

Othandizira a Gulu 1 ndi omwe atsimikiza mtima kuyambitsa khansa mwa anthu. Kumbali ina, othandizira 4, akuphatikizanso othandizira omwe mwina samayambitsa khansa.

Kumbukirani kuti gulu ili silizindikira chiwopsezo chokhudzana ndi khansa. Zimangowonetsa kuchuluka kwa umboni wotsimikizira kulumikizana pakati pa ma carcinogens ndi khansa.

Zotsatira za IARC

Mu 2015, akatswiri 22 ochokera kumayiko 10 adakumana kuti aunike kafukufuku yemwe alipo kale wokhudza kulumikizana pakati pa nyama yofiira ndi khansa.

Adawunikanso maphunziro opitilira 800 pazaka 20 zapitazi. Kafukufuku wina adayang'ana nyama yofiira yokhayokha kapena yosakonzedwa. Ena adawayang'ana onse awiri.

Zotsatira za IARC zikuwonetsa kuti:

• Kudya nyama yofiira pafupipafupi mwina ukuwonjezeka chiopsezo chanu cha khansa yoyipa.
• Kudya nyama yokonzedwa pafupipafupi amachuluka chiopsezo chanu cha khansa yoyipa.

Anapezanso umboni wosonyeza kulumikizana pakati pakudya nyama yofiira ndi khansa ya prostate ndi khansa ya kapamba, koma kafukufuku wina amafunika.

Pofuna kuchepetsa chiopsezo cha khansa, pewani nyama yosinthidwa

Ngati mukuyang'ana kuti muchepetse chiopsezo cha mitundu yambiri ya khansa, mwina pewani kudya nyama zomwe zasinthidwa.

IARC idasankha nyama yosakidwa ngati khansa ya Gulu 1. Mwanjira ina, pali kafukufuku wokwanira wosonyeza kuti zimayambitsa khansa mwa anthu. Kuti ndikupatseni malingaliro ena, nayi ma carcinogen ena a Gulu 1:

• fodya
• UV cheza
• mowa

Apanso, gulu ili limakhazikitsidwa ndi umboni wotsimikizira kulumikizana kwa khansa ndi wothandizirayo.

Ngakhale pali umboni wamphamvu wosonyeza kuti othandizira onse a Gulu 1 amayambitsa khansa mwa anthu, sizitanthauza kuti onse amakhala pachiwopsezo chofanana.

Mwachitsanzo, kudya galu wotentha sikuli kofanana ndi kusuta ndudu zikafika pachiwopsezo cha khansa.

Ripoti la IARC linamaliza kuti kudya magalamu 50 a nyama yosinthidwa tsiku lililonse kumawonjezera chiopsezo cha khansa ndi 18 peresenti. Malinga ndi American Cancer Society, izi zitha kubweretsa chiopsezo cha khansa ya m'matumbo kuyambira 5% mpaka 6%.

Kuti muwone, magalamu 50 a nyama yosinthidwa amatanthauzira pafupifupi galu mmodzi wotentha kapena magawo angapo a nyama yopatsa nyama.

Akatswiri amati amangodya nyama izi kamodzi kanthawi. Ganizirani kusangalala nawo pazochitika zapadera m'malo mowapanga kukhala chakudya chanu cha tsiku ndi tsiku.

Samalani ndi kudya nyama yofiira

Nyama yofiira yosatulutsidwa ndi gawo la chakudya choyenera kwa anthu ambiri. Amapereka kuchuluka kwa:

• mapuloteni
• mavitamini, monga B-6 ndi B-12
• mchere, kuphatikizapo chitsulo, zinc, ndi selenium

Komabe, lipoti la IARC linatsimikiza kuti kudya nyama yofiira pafupipafupi kumawonjezera mavuto ku khansa zina.

Palibe chifukwa choduliratu zakudya zanu, ngakhale zili choncho. Ingoyang'anirani momwe mumakonzera komanso kuchuluka kwa zomwe mumadya.

Njira zophikira

Akatswiri a IARC adanenanso mu lipoti lawo kuti momwe mumaphikira nyama yofiira zitha kukhala pachiwopsezo cha khansa.

Kuphika, kuwotcha, kusuta, kapena kuphika nyama pamalo otentha kwambiri kumawonjezera ngozi. Komabe, akatswiri a IARC adalongosola kuti panalibe umboni wokwanira wopereka malingaliro aliwonse aboma.

Nayi njira yathu yopangira nyama kukhala yathanzi momwe mungathere.

Malangizo othandizira

Olemba lipoti la IARC adazindikira kuti palibe chifukwa chosiya kwathunthu nyama yofiira yosasinthidwa. Koma ndibwino kuchepetsa kuchepa kwanu mpaka katatu pamlungu.

Nyama yofiira yodyera kamodzi imakhala pafupifupi ma ola atatu kapena anayi (85 mpaka 113 magalamu). Izi zikuwoneka ngati:

• hamburger imodzi yaying'ono
• nkhumba imodzi ya nkhumba
• nyama yang'ombe yaying'ono

Onjezerani nyama yofiira m'malo mwa zakudya zanu

Ngati nyama yofiira kapena yophika imapanga zakudya zambiri, lingalirani zosinthanitsa.

Nawa malingaliro pochepetsa kudya kwanu kofiira:

• Mu msuzi wa pasitala, tengani theka la nyama yomwe mungagwiritse ntchito ndi kaloti wodulidwa bwino, udzu winawake, bowa, tofu, kapena kuphatikiza.
• Mukamapanga ma burger, gwiritsani ntchito nkhuku kapena nkhuku m'malo mwa ng'ombe. Kwa burger wopanda nyama, gwiritsani nyemba zakuda kapena tempeh.
• Onjezerani nyemba ndi mphodza ku msuzi ndi msuzi wa kapangidwe ndi mapuloteni.

Mukuyang'ana kusiya nyama yosinthidwa? Malangizo awa atha kuthandiza:

• Sinthani mabala ozizira mu sangweji yanu ndi magawo a nkhuku yokazinga kapena Turkey.
• Sankhani zophika nkhuku kapena masamba m'malo mwa pepperoni kapena nyama yankhumba.
• Yesani nyama zamasamba. Mwachitsanzo, gwiritsani ntchito soya chorizo ​​mu burritos kapena seitan mu zotumphukira. Onjezerani masamba a utoto, kapangidwe, ndi zowonjezera zowonjezera.
• Sinthanitsani mazira ndi yogurt mukamadya chakudya cham'mawa, monga nyama yankhumba kapena soseji.
• M'malo mokazinga agalu otentha, poto wowotchera mwatsopano kapena wopanda chotchingira cha bratwurst kapena masoseji.

Mfundo yofunika

Nyama yofiira yakhala ikuwunikidwa poyang'ana momwe ingathere pamagulu angapo azaumoyo, kuphatikiza khansa. Akatswiri tsopano akukhulupirira kuti kudya nyama yofiira pafupipafupi kumatha kukulitsa chiopsezo cha khansa yoyera.

Akatswiri amavomerezanso kuti pali umboni wokwanira wonena kuti kudya nyama yambiri yosinthidwa kumawonjezera chiopsezo cha khansa.

Koma palibe chifukwa chodulira nyama yofiira pazakudya zanu kwathunthu. Ingoyesani kumamatira ku nyama yofiira yosagulitsidwa bwino kwambiri, ndikuchepetsani zomwe mumadya kamodzi kokha sabata iliyonse.
