Soya amatsutsana kwambiri ngati chakudya. Ena mpaka amachifotokoza ngati carcinogenic, ena amati chimateteza ku khansa. Kumveka bwino za khansa ya m'mawere kudabwera kumapeto kwa chaka cha 2015 pomwe ofufuza ku Yunivesite ya Illinois / USA adapeza momwe soya imafulumizitsa kukula kwa khansa ya m'mawere komanso momwe soya angachepetsere khansa ya m'mawere. Chifukwa chake zimatengera kwambiri ngati mukudya zinthu zabwino za soya kapena kutenga ma isoflavones akutali ngati chowonjezera chazakudya.
Soya - Carcinogenic kapena anti-cancer
Nyemba za soya ndizopangira zakumwa za soya, yogati ya soya, zonona za soya, ufa wa soya komanso tofu, soseji wa tofu, ndi zina zambiri. Ndipo pamene zakudya zonsezi zikukula kutchuka, pali otsutsa omwe samaphonya mwayi wochenjeza mokweza za soya.
Pankhani ya chiopsezo cha khansa ya m'mawere kuchokera ku soya, payenera kukhala zomveka bwino pankhaniyi:
Mu April 2015, ofufuza a ku yunivesite ya Illinois adafalitsa zotsatirazi zomwe zikuwonetsa chifukwa chake soya nthawi zambiri amatchedwa carcinogen, koma kumbali ina, akulimbikitsidwanso kupewa khansa ya m'mawere:
Asayansi anajambula jini zomwe zimakhudzidwa ndi phytonutrients (zomera zachiwiri) mu soya. Adapeza kuti ufa wa soya wopangidwa pang'ono umapondereza khansa ya m'mawere, pomwe ma isoflavone akutali amalimbikitsa majini omwe amafulumizitsa kukula kwa chotupa.
Kafukufukuyu adasindikizidwa mu nyuzipepala ya Molecular Nutrition and Food Research.
Gulu lina loyesera linalandira chakudya cha ufa wa soya ndi osakaniza a isoflavone omwe mwachibadwa amakhala mu ufa, gulu lina linalandira kusakaniza ndi isoflavones (popanda ufa wa soya). Chakudya chilichonse chinali ndi ma genistein 750 ppm, kuchuluka kwake kofanana ndi komwe mkazi amadya zakudya za ku Asia zomwe nthawi zambiri zimakhala ndi soya.
Genistein ndiye isoflavone yayikulu mu soya ndipo kafukufuku wambiri pazaka zingapo zapitazi awonetsa nkhawa za zotsatira za nthawi yayitali za genistein ndi gawo lake mu carcinogenesis. Ofufuza aku Illinois adayankha zovuta izi kuti afotokozere bwino zomwe zikuchitika.
Kusiyana kwakukulu: kumwa soya kapena chowonjezera chazakudya chopangidwa kuchokera ku isoflavones
Azimayi a ku Asia ali ndi mwayi wocheperako kuwirikiza katatu kapena kasanu kudwala khansa ya m’mawere kusiyana ndi amayi amene amadya zakudya za kumayiko a kumadzulo. Ofufuza ena amafotokoza kuchepetsedwa kwa chiwopsezo cha khansa ya m'mawere ndikumwa soya komwe kuli kofala ku Asia. Komabe, akazi a ku Asia amadya tofu ndi zinthu zina za soya, pamene akazi a Kumadzulo nthaŵi zambiri amapatsidwa ma isoflavones olekanitsidwa ndi soya monga chowonjezera cha zakudya.
Funso lomwe asayansi adafunsa tsopano linali ngati ma isoflavones odzipatula - omwe amayi ambiri akumadzulo samatenga mpaka chiyambi cha kusintha kwa thupi - angapereke ubwino wathanzi wofanana ndi kumwa kwa moyo wonse wa tofu ndi soya ku Asia. Ayi, sangathe!
Zomwe timagogomezera nthawi zonse kuchokera kumalingaliro onse - kutanthauza kuti chinthu chodzipatula sichikhala chofanana ndi mankhwala odzaza ndi zotsatira zake - tsopano zatsimikiziridwa ndi asayansi ponena za soya ndi soya isoflavones.
Ngati mankhwala a soya abwino adyedwa, monga ufa wa soya wa B. kapena mankhwala a tofu, ndiye kuti majini omwe amaletsa zotupa amayamba kugwira ntchito. Panthawi imodzimodziyo, majini amaponderezedwa omwe angalimbikitse kukula kwa chotupa ndi kufalikira kosalamulirika kwa maselo a khansa.
Soya kumalimbitsa chitetezo cha m'thupi, isoflavones kufooketsa chitetezo cha m'thupi
Chofunika kwambiri kwa ife chinali chakuti ufa wa soya umapangitsa kuti chitetezo cha mthupi chitetezeke, chomwe chingafotokozenso chifukwa chake sichinapangitse kukula kwa chotupa, "anatero katswiri wofufuza Yunxian Liu (PhD mu Human Nutrition and Master of Statistics). Ma isoflavone akutaliwo adayambitsa majini omwe amalimbikitsa khansa ndipo amafooketsa chitetezo cha mthupi ndipo motero amatha kufunafuna ndikuwononga maselo a khansa.
Liu adapezanso kuti ma isoflavones akutali adalimbikitsa majini awiri omwe adatsogolera kupulumuka kwakanthawi kwa amayi omwe ali ndi khansa ya m'mawere. Panthawi imodzimodziyo, jini ina yomwe ingawonjezere kupulumuka inaponderezedwa.
Za khansa ya m'mawere: Zogulitsa za soya zabwino - inde! Isoflavones ngati chowonjezera pazakudya - ayi!
Zotsatira za Liu zimathandizira lingaliro lotchedwa Soy Matrix Effect, malinga ndi momwe chitetezo cha khansa cha soya chimachokera ku chakudya chonse. Chifukwa chake si ma isoflavones, koma kuphatikiza kwa zinthu zonse zopezeka mu soya zomwe zimabweretsa thanzi labwino.
Zinalinso zosangalatsa kuti magulu onsewa amadya kuchuluka kwa genistein. Mmodzi paokha ndi wina pa chakudya chonse - ndipo pamene zinthu zodzipatula zinali zovulaza, zinthu zomwezo pamodzi ndi zinthu zina zonse za soya zingakhale zopindulitsa kwambiri.
Azimayi omwe ali ndi khansa ya m'mawere sayenera kumwa zakudya zowonjezera zokhala ndi isoflavones zamtundu wa soya, koma zinthu za soya monga mwachitsanzo B. Phatikizani tofu, tempeh, kapena ufa wa soya muzakudya zopatsa thanzi zokhala ndi zinthu zofunika kwambiri zomwe zili ndi zipatso zambiri, nyemba, ndiwo zamasamba, ndi mbewu zonse.
