Oncology amamasuliridwa kuchokera ku Chigriki kuti "kulemera" kapena "katundu" ndipo ndi nthambi yonse yamankhwala yomwe imaphunzira zotupa zabwino komanso zowopsa, momwe zimachitikira komanso kukula kwawo, njira zodziwira matenda, chithandizo ndi kupewa.
Kuchokera kumalingaliro amalingaliro, zotupa zilizonse (neoplasms, zophuka) nthawi zonse zimakhala zosafunikira m'thupi la munthu. Kuchita motsutsana ndi dongosolo lothandizira moyo wonse, makamaka ngati zilonda zatsimikiziridwa, matendawa amawoneka kuti amachititsa munthu kuganiza za katundu wa maganizo "obisika mkati". Mphamvu yoipa ya malingaliro, makamaka mantha, imapangitsa maganizo a munthu kukhala wokhumudwa, mphwayi, ndipo ngakhale kusafuna kukhala ndi moyo. Kuonjezera apo, imalepheretsa kwambiri chitetezo cha mthupi ndi mahomoni a thupi, omwe ali ndi zotsatira zoipa kwambiri pa khalidwe la ntchito yake. Zotsatira zake zimatha kudzutsa maselo owopsa.
Malinga ndi World Health Organisation, Pofika 2035, anthu okwana 24 miliyoni adzakhala ndi khansa chaka chilichonse. Bungwe la World Cancer Research Foundation lati matenda a khansa amatha kuchepetsedwa ndi gawo limodzi mwa magawo atatu ngati aliyense atakhala ndi moyo wathanzi. Akatswiri amakhulupirira kuti pofuna kupewa matendawa, ndikwanira kusunga mfundo zochepa chabe, zomwe mbali yofunika kwambiri imaperekedwa ku zakudya ndi masewera olimbitsa thupi. Panthawi imodzimodziyo, ponena za zakudya, tikulimbikitsidwa kudya zakudya zambiri zochokera ku zomera.
Chimachitika ndi chiyani ngati mumatsutsa khansa ndi zakudya zochokera ku zomera?
Kuti tiyankhe funsoli, tikutembenukira ku maphunziro akunja. Dr. Dean Ornish, mkulu wa Preventive Medicine Research Institute ku California, ndi anzake apeza kuti kupitirira kwa khansa ya prostate kungathe kuimitsidwa mwa kudya zakudya za zomera ndi moyo wathanzi. Asayansi amadontha magazi a odwala, omwe nthawi zambiri amadya nyama ndi mkaka komanso zakudya zofulumira, m'maselo a khansa omwe amamera m'mbale ya petri. Kukula kwa maselo a khansa kunachepetsedwa ndi 9%. Koma atatenga magazi a anthu amene amatsatira zakudya zochokera ku zomera, asayansi anapeza mphamvu yodabwitsa. Magazi amenewa amachepetsa kukula kwa maselo a khansa pafupifupi ka 8!
Kodi zimenezi zikutanthauza kuti chakudya cha zomera chimapangitsa thupi kukhala lamphamvu kwambiri chonchi?
Asayansi adaganiza zobwereza kafukufukuyu ndi matenda odziwika bwino pakati pa azimayi - khansa ya m'mawere. Adayika ma cell a khansa ya m'mawere m'mbale ya Petri kenako ndikudontha magazi a amayi omwe amadya chakudya chamtundu wa American m'maselo. Kuwonetsedwa kwawonetsa kupondereza kufalikira kwa khansa. Kenako asayansiwo ananena kuti akazi omwewo asinthe n’kuyamba kudya zakudya za m’mbewu ndipo anawalamula kuti aziyenda kwa mphindi 30 patsiku. Ndipo kwa milungu iwiri, amayiwo adatsatira zomwe adalangizidwa.
Ndiye chakudya chochokera ku zomera chinachita chiyani m'milungu iwiri yokha motsutsana ndi ma cell atatu a khansa ya m'mawere?
Patatha milungu iwiri, asayansi adatenga magazi kuchokera ku maphunzirowo ndikuwukhetsa pa maselo a khansa, ndipo chifukwa chake, magazi awo anali ndi mphamvu kwambiri, chifukwa maselo ochepa chabe a khansa adatsalira mu chikho cha Peter. Ndipo awa ndi milungu iwiri yokha ya moyo wathanzi! Mwazi wa akazi wayamba kugonjetsedwa ndi khansa. Magaziwa awonetsa kuthekera kochepetsera kwambiri komanso kuyimitsa kukula kwa maselo a khansa mkati mwa milungu iwiri yokha mutatsatira malangizowo.
Choncho, asayansi anatsimikiza zimenezo chimodzi mwa zifukwa za kudzutsidwa ndi kukula kwa maselo a khansa ndi kuperewera kwa zakudya m'thupi, kugwiritsa ntchito zinthu zovulaza ndipo, koposa zonse, kuchuluka kwa mapuloteni a nyama. Ndi zakudya zotere, kuchuluka kwa mahomoni m'thupi la munthu kumawonjezeka, zomwe zimakhudza mwachindunji kukula ndi chitukuko cha oncology. Kuonjezera apo, ndi mapuloteni a nyama, munthu amalandira amino acid wochuluka wotchedwa methionine, omwe mitundu yambiri ya maselo a khansa imadya.
Pulofesa Max Parkin, katswiri wofufuza za khansa ku UK ku Queen Mary University ku London, ananena izi:
Ndipo si zimenezo. M'mbuyomo, yunivesite ya Southern California inatumiza nkhani ya atolankhani yokhala ndi mutu wovuta kwambiri . Inanena kuti kudya zakudya zokhala ndi mapuloteni ambiri a nyama, makamaka azaka zapakati, kuchulukitsa mwayi wa kufa ndi khansa kuwirikiza kanayi. Izi zikufanana ndi ziwerengero zomwe zilipo kwa osuta.
Kafukufuku waposachedwa kwambiri wochokera ku Queen Mary University ku London akuwonetsa kuti kusuta ndiye vuto lalikulu kwambiri la khansa lomwe wosuta aliyense angapewe. Ndipo m'malo mwachiwiri ndi zakudya, zosakwanira bwino komanso kuchuluka kwambiri.
Malinga ndi kafukufuku wokhudza zaka zisanu kuyambira 2007 mpaka 2011, oposa 300 zikwi zikwi za khansa chifukwa cha kusuta analembetsa. Enanso 145 adalumikizidwa ndi zakudya zopanda thanzi komanso zakudya zambiri zokonzedwa m'zakudya. Kunenepa kwambiri kunapangitsa kuti pakhale matenda a khansa 88, ndipo mowa unathandizira kukula kwa khansa mwa anthu 62.
Ziwerengerozi ndizokwera kwambiri kuti musamangokhala osachita chilichonse ndikunyalanyaza zenizeni. N’zoona kuti palibe amene angadzutse munthu aliyense kuti akhale ndi udindo wosamalira thanzi lake, kupatulapo munthuyo. Koma ngakhale munthu mmodzi amene amasunga thanzi lake ndiye chizindikiro chofunika kwambiri chomwe chimakhudza thanzi la mtundu wonse ndi anthu onse.
Inde, kuwonjezera pa thanzi labwino la maganizo, zakudya zoyenera ndi zizoloŵezi zoipa, pali zinthu zosatsutsika, zofunika kwambiri monga majini ndi chilengedwe. Zachidziwikire, zimakhudza thanzi la aliyense wa ife, ndipo sitikudziwa motsimikiza chomwe chingakhale mphindi yofunika kwambiri ya matendawa. Koma ngakhale izi, mwina kuli koyenera kuganiza tsopano ndikudzipangira nokha moyo wabwino womwe ungayambitse kuponderezedwa kwa matendawa, kuchepetsa mtengo wokhala ndi thanzi labwino komanso mzimu wabwino.
