Abantu abadla i-soy ngokusobala bavikelekile kangcono kumdlavuza wamaphaphu kunabantu abangathandi imikhiqizo yesoya, njengoba kuboniswe ezifundweni ezihlukahlukene. Cishe i-antioxidant isoflavones evela kubhontshisi wesoya enesibopho somphumela wokuvikela.
Umdlavuza Wesoya Nomdlavuza Wamaphaphu
Imikhiqizo ye-soy ngezinye izikhathi ibizwa ngokuthi iyingozi futhi ngisho ne-carcinogenic. Uma lokhu bekunjalo, nokho, bekuzodingeka futhi kwenzeke ukuhlonza ukuxhumana okuhambisanayo ezifundweni ze-epidemiological. Lawo maqembu emphakathini adla kakhulu imikhiqizo yesoya kufanele abe maningi amathuba okuba athole umdlavuza. Nokho, okuphambene kunjalo, njengoba sizobonisa ngezansi sisebenzisa isibonelo somdlavuza wamaphaphu.
Ukungabhemi nje akuvikeli umdlavuza wamaphaphu
Umdlavuza wamaphaphu uwuhlobo lomdlavuza obangela ukufa kwabantu abaningi okuhlobene nomdlavuza emhlabeni wonke - kuwo womabili amazwe athuthukile nasathuthuka. Ukubhema kungenye yezimbangela eziyinhloko zomdlavuza wamaphaphu, kangangokuthi ingxenye yesine yazo zonke iziguli ezinomdlavuza wamaphaphu cishe zaba nawo ngoba zibhema. Kodwa lokho futhi kusho ukuthi amaphesenti angu-75 azo zonke izifo zomdlavuza wamaphaphu awahlangene nokubhema. Ngakho-ke uma ukungabhemi kukodwa kungenasivikelo, yini engenziwa ukuze kuvinjelwe umdlavuza wamaphaphu?
Ukudla okunomsoco kunciphisa ingozi yomdlavuza wamaphaphu
Ukudla okunomsoco kuyisici esibalulekile sokuvimbela. Ushukela, isibonelo, kufanele ugwenywe njengoba ukudla okunoshukela omningi kungandisa ingozi yomdlavuza wamaphaphu, kuyilapho ukudla okune-fiber eningi kanye nenala yezithelo nemifino kuvikela amaphaphu. Kuyaziwa ngezifundo zezilwane kanye ne-in-vitro ukuthi isoyi nayo inomphumela wokuvikela kumdlavuza. Kulezi zifundo, okuqukethwe okuphezulu kwe-isoflavone kubhontshisi wesoya kwakwazi ukuvimbela ukuthuthukiswa komdlavuza futhi kwaholela ekubikezelweni okungcono esimweni somdlavuza okhona.
I-soy isoflavones ivimbela umdlavuza
Ama-isoflavones avimbela i-angiogenesis kanye ne-metastasis futhi aphinde alwe nengcindezi ye-oxidative, ngakho-ke nawo ayingxenye yeqembu lama-antioxidants. I-Angiogenesis (ehlobene nomdlavuza) ukwakheka kwemithambo yegazi emisha ehlinzeka ngemisoco esimila, okubangela ukuba sikhule ngokushesha futhi okuholela ekuqaguleni okubi.
I-Isoflavones yizinto zezitshalo ezivela eqenjini le-flavonoid. Atholakala ikakhulukazi kubhontshisi wesoya, kodwa angatholakala futhi ngamanani amancane kuphizi, uphizi, nobhontshisi. I-soy isoflavones ejwayelekile ibizwa ngokuthi i-genistein ne-daidzein.
Njengoba ukusetshenziswa kwe-soy kuboniswe ezifundweni ze-epidemiological ukuthi kube usizo futhi kuvikeleke ezinhlotsheni zomdlavuza ezincike ku-hormone (umdlavuza webele, wesibeletho kanye ne-ovary), kukholakala ukuthi ama-isoflavone abopha ku-estrogen receptor futhi ngaleyo ndlela anciphise ukukhula komdlavuza noma ukuqhubeka komdlavuza. ikhefu. Ngoba uma ama-isoflavone evimba ama-estrogen receptors, ama-estrogens awasakwazi ukuma kuma-receptors futhi ngaleyo ndlela angasakwazi ukushayela umdlavuza.
Isoya ivikela ikakhulukazi abesifazane nabangabhemi
Ama-Estrogen receptors nawo adlala indima ebalulekile kumdlavuza wamaphaphu, yingakho umphumela wokuvikela wemikhiqizo yesoya maqondana nomdlavuza wamaphaphu wahlolwa ekuhlaziyweni okuphelele kwe-meta ngo-2011. Ngale njongo, izifundo ze-epidemiological ze-11 ngalesi sihloko zahlaziywa.
Kuvele ukuthi abesifazane ikakhulukazi bangazuza ezicini zokuvikela zikabhontshisi wesoya. Ingozi yabo yokuba nomdlavuza wamaphaphu yehle ngamaphesenti angama-21 uma bejabulela ukudla imikhiqizo yesoya. Abangabhemi babenengozi ephansi ngamaphesenti angama-38 yokuba nomdlavuza wamaphaphu uma bevame ukudla isoso. Imiphumela eyingozi yokubhema ibonakala igcwele abantu ababhemayo, ngakho ukusetshenziswa kwesoya akukwazi ukusiza lapha. Ngokwesilinganiso, ososayensi babonise amaphesenti angu-23 anciphisa ingozi yomdlavuza wamaphaphu (ukusetshenziswa okuphezulu kwesoya uma kuqhathaniswa nokusetshenziswa kwesoya okuphansi).
Eminyakeni emibili kamuva (2013), imiphumela engenhla yaqinisekiswa ku- Nutrition and Cancer: Nakuba ukuvikelwa komdlavuza wamaphaphu ekusetshenzisweni kwesoya kwakuphansi ekuhlaziyeni kwakamuva, kwashiwo lapha ukuthi abangabhemi ikakhulukazi bayazuza ekusetshenzisweni kwesoya.
I-tofu nobisi lwesoya kunciphisa ingozi yomdlavuza wamaphaphu
Kuyathakazelisa ukuthi ekuhlaziyeni kwango-2011, imikhiqizo yesoya engavutshiwe kuphela ebonise umphumela wokuvikela umdlavuza wamaphaphu (i-tofu, i-edamame, nobisi lwesoya), kodwa hhayi imikhiqizo yesoya evutshiwe njenge-miso ne-natto. Nokho, ucwaningo lwangaphambili luye lwabonisa ukuthi i-miso inomphumela ovikelayo kumdlavuza webele, wesisu, nowokhololo.
Njengoba abantu abathanda ukudla isoyi ngokuvamile badla futhi baphile impilo enempilo, okungukuthi benza imidlalo eminingi futhi baphuze utshwala obuncane, ngokuvamile kuthiwa yindlela yokuphila yonke enomphumela wokuvikela. Ezifundweni eziningi ezihloliwe, nokho, lawa mathonya engeziwe aye acatshangelwa. Njengoba abantu base-Asia benokudla okuphezulu kwe-soy kunabaseYurophu, okokuqala kukhombisa umphumela wokuvikela kunalokhu kwakamuva.
Iziguli ezinomdlavuza wamaphaphu ziphila isikhathi eside uma zidla isoyi
Inkambo yomdlavuza wamaphaphu nayo ibonakala inethemba elikhulu uma labo abathintekile benemikhiqizo yesoya ekudleni kwabo. Ngaphezu kwalokho, abacwaningi abavela eVanderbilt University Medical Centre (Nashville, Tennessee) kanye neShanghai Cancer Institute (Shanghai, China), kanye neNational Cancer Institute babhala kuyi-Journal of Clinical Oncology ngo-2013 ukuthi abesifazane abanomdlavuza wamaphaphu baphila isikhathi eside uma kakade emikhiqizweni yesoya Esetshenzisiwe njalo ngaphambi kokuxilongwa kwayo.
