Sekuyisikhathi eside kwaziwa ukuthi inyama yandisa amathuba okuba nomdlavuza - ikakhulukazi uma udle inyama eningi futhi uma inyama ilungiswe ngendlela ethile. Imikhiqizo ebhenywayo, eyosiwe, nesoseji ibhekwa njengeyingozi kakhulu. Manje sekuvele ukuthi imikhiqizo enjalo yenyama iyingozi nakulabo abake baba nomdlavuza futhi okucatshangwa ukuthi sebelaphekile. Ababephethwe wumdlavuza webele basheshe bafe uma bethanda ukudla inyama kunabesifazane ababenomdlavuza webele kodwa beyigwema inyama.
Kungcono ungabi nanyama uma unomdlavuza webele
Labo asebenomdlavuza webele futhi okucatshangwa ukuthi sebelashiwe kufanele badle inyama encane noma bangayidli nhlobo, kusho ucwaningo olusha. Uma kungenjalo, inyama ingandisa ingozi yokufa. Lokhu okutholakele kusha sha. Iqiniso lokuthi ukudla inyama kungandisa ingozi yomdlavuza selaziwa kudala, njengoba sibike ezihlokweni ezedlule:
Ukudla inyama kwandisa umdlavuza
Ngokwesibonelo, ngo-2009, abacwaningi e-US National Cancer Institute babhala ngocwaningo olubonisa ukuthi abantu abadla inyama ebomvu negayiwe (ingulube, yenkomo, neyewundlu) banamathuba amaningi okuba nomdlavuza wamaphaphu, umdlavuza wamaphaphu, umdlavuza womminzo kanye nomdlavuza wamaphaphu. umdlavuza wesibindi. Amathuba okuba nomdlavuza wesibindi ayephezulu kakhulu. Yayiphakeme ngamaphesenti angu-60 kunabantu abadla inyama encane noma abangayidli nhlobo.
Izinto eziningi ze-carcinogenic enyameni
Izinhlanganisela ezihlukahlukene ze-carcinogenic zitholakala enyameni nasemikhiqizweni yenyama egayiwe, isb B. heme iron, nitrites, heterocyclic amines, polycyclic aromatic hydrocarbons, njll.
Zonke lezi zinto zingathonya i-hormone metabolism, ukusheshisa ukuhlukana kwamangqamuzana, kukhuthaze ukuvuvukala okungapheli, kulimaze izinto zofuzo (futhi ngaleyo ndlela kuholele ekuguqukeni kwezakhi zofuzo), kwandise izinga lokukhula kwezici futhi kwandise inani lama-radicals mahhala, konke ekugcineni okuholela emdlavuza ukuhola.
Ingozi ephezulu yomdlavuza wesinye kanye nesisu ngenxa yenyama
Sekuvele kwaziwa kusukela ngo-2010 ukuthi inyama yandisa ingozi yomdlavuza wesinye. Ngawo lowo nyaka, kwashicilelwa ucwaningo lwesikhathi eside olwenziwa eminyakeni engama-20. Kwabesifazane abangu-60,000 30, kutholakale ukuthi labo abadla inyama njalo basengozini enkulu ngamaphesenti angu- yomdlavuza womlomo wesibeletho.
Uma kusetshenziswa i-heme iron eyengeziwe, kwandisa ingozi yomdlavuza wesisu, ngokusho kocwaningo lwango-2012.
Ingozi ephezulu yomdlavuza wezinso nowomphimbo ovela enyameni
Ngemva konyaka, kwatholakala ukuthi inyama yandisa ingozi yomdlavuza wezinso. Abacwaningi baseZurich babonise ngo-2013 ukuthi ngisho nesoseji elilodwa ngosuku landisa ingozi yesifo senhliziyo, umdlavuza, nezinye izifo eziningi ezingalapheki kakhulu. Futhi ngo-2013, ngemva kokucwaninga abantu abangu-480,000, abacwaningi baseSpain babhala ukuthi labo abadla inyama eningi basengozini enkulu yokuba nomdlavuza womphimbo.
Into entsha ye-carcinogenic etholwe enyameni
Ngo-2014, uProf. Ajit Varki waseNyuvesi yaseCalifornia, eSan Diego School of Medicine wathola umdlavuza olandelayo enyameni, icarbohydrate ethile ebizwa ngokuthi i-Neu5Gc. Lokhu kutholakala ezilwaneni eziningi, kodwa hhayi kubantu.
Ngakho-ke, umzimba womuntu wenza ama-antibodies ngokumelene nama-carbohydrate ngemva kokudliwa kwenyama yonke, futhi ngokuhamba kwesikhathi - uma inyama idliwa ngokuphindaphindiwe - izinqubo zokuvuvukala ezingapheli zenzeka ngenxa yalokhu kwakheka kwe-antibody. Into futhi ayikwazi ukucutshungulwa noma ikhishwe ngokuphelele. Kunalokho, igcinwa emzimbeni, ikakhulukazi esibindini, lapho ingase ibangele izimila zesibindi.
Inyama yandisa ingozi yomdlavuza webele
Ocwaningweni olusha olushicilelwe ngoJanuwari 2017, uDkt. Humberto Parada waseNyuvesi yaseNorth Carolina kuJournal of the National Cancer Institute ukuthi ukudla inyama eningi kwandisa ingozi yomdlavuza webele. Kodwa hhayi lokho kuphela. Ngisho noma owesifazane engawunqoba umdlavuza webele uma eqhubeka nokudla inyama eningi ngemva kokuphulukiswa, ingozi yakhe yokufa ngaphambi kwesikhathi iyakhula.
Njengamanje kunabesifazane abangaphezu kwezigidi ezingu-2.8 abaye banqoba umdlavuza webele e-United States kuphela. Kodwa-ke, uma ufuna ukujabulela impilo entsha onikezwe yona isikhathi eside ngangokunokwenzeka, kufanele unake ukudla kwakho - futhi kunalokho ungayidli enye inyama. Ngoba ukudla okubhenywayo, okugazingiwe nokosiwe kwenza impilo ibe mfushane.
Ukudla inyama kwenza impilo ibe mfushane ngisho nangemva kokusinda kumdlavuza webele
UParada nozakwabo benza inhlolovo kwabesifazane abangaphezu kuka-1,500 1996 okwatholakala ukuthi banomdlavuza wamabele phakathi kuka-1997 no-10—ngesikhathi bexilongwa, ngemva kweminyaka emihlanu, futhi ngemva kweminyaka eyi-.
Ngesikhathi socwaningo, bangu-597 abesifazane abashonile, abangu-237 kubo bebulawa umdlavuza webele owawubuyile. Abanye besifazane babulawa ezinye izifo.
Ithole ukuthi abesifazane abadla inqwaba yokudla okugazingiwe nokubhenywayo basengcupheni enkulu engamaphesenti angu-23 yokubulawa umdlavuza webele, nakuba babeke bawunqoba. Ingozi yabo yokufa ngenxa yezinye izifo inyuke ngamaphesenti angu-31 uma kuqhathaniswa nalabo besifazane abadla inyama encane noma abangayidli nhlobo.
Ukudla okusekelwe ezitshalweni kuvikela umdlavuza webele
Ukudla okuqukethe ikakhulukazi ukudla okusekelwe ezitshalweni, ngakolunye uhlangothi, kuqukethe izinto eziningi ezingavikela futhi zilwe nomdlavuza. Lokhu kufaka phakathi, isibonelo, i-linseed, amahalananda, ujinja, ama-walnuts, isoyi, nokunye okuningi, kanye nezinto ezibalulekile njengovithamini D.
Kuyathakazelisa ukuthi konke lokhu kudla futhi kuvikela kwezinye izifo eziningi, isb B. ngokumelene nezikhalazo zesimiso senhliziyo nemithambo yegazi. Akumangalisi, ngoba bonke banomphumela wokulwa nokuvuvukala - futhi ukuvuvukala okungapheli kuyimbangela ebalulekile yezifo ezingapheli. Ngakho-ke, ukudla okusekelwe ezitshalweni akukwazi nje ukunciphisa ingozi yomdlavuza nomdlavuza webele, kodwa ingozi yonke yezifo nokufa.
