Ikiganiro kijyanye na soya na kanseri bishobora gutera impaka, cyane cyane kubera impungenge zijyanye nibiri muri phytoestrogène. Phytoestrogène, cyane cyane isoflavone iboneka muri soya, yarasuzumwe kubera ko isa na estrogene, imisemburo izwiho kugira uruhare mu mikurire ya kanseri zimwe na zimwe. Ibitekerezo byambere byavugaga ko ibyo bikoresho bishobora gukora nka estrogene mu mubiri, bikaba byongera ibyago bya kanseri. Ibi byatumye habaho imitwe yunvikana kandi ihangayikishijwe cyane numutekano wa soya. Nyamara, ubushakashatsi buherutse gushushanya ubundi buryo, bugaragaza ko soya ishobora gutanga inyungu zo kwirinda kanseri.

Gusobanukirwa na Phytoestrogene

Phytoestrogène ni ibimera biva mu bimera bifite imiterere isa na estrogene, imisemburo yambere yimibonano mpuzabitsina y'abagore. Nubwo imiterere yabo isa, phytoestrogène yerekana ingaruka nke za hormone ugereranije na estrogene ya endogene. Ubwoko bwibanze bwa phytoestrogene harimo isoflavone, lignans, na coumestans, hamwe na isoflavone yiganje cyane mubicuruzwa bya soya.

Phytoestrogène yigana estrogene bitewe nuburyo bwimiti yabyo, ibemerera guhuza reseptor ya estrogene mumubiri. Nyamara, guhuza kwabo ni munsi cyane ugereranije na estrogene karemano, bikavamo ingaruka nke za hormone. Uku guhuza na estrogene kwateye impungenge ku ngaruka zabyo ku miterere y’imisemburo ya hormone, cyane cyane kanseri y'ibere, iterwa na estrogene.

Ubwoko bwa Phytoestrogene

⚫️ Isoflavones: Biboneka cyane cyane muri soya na soya, isoflavone nka genistein na daidzein ni phytoestrogène yizwe cyane. Bazwiho ubushobozi bwo gukorana na reseptor ya estrogene kandi akenshi ni byo byibandwaho mubushakashatsi kubyerekeye ingaruka zubuzima bwabo.

Lignans : Kugaragara mu mbuto (cyane cyane flaxseeds), ibinyampeke byose, n'imboga, lignans ihindurwa na bagiteri yo mu nda ikinjira muri enterolignans, nayo ifite ibikorwa byoroheje bya oestrogene.

⚫️ Coumestans: Ibi ntibisanzwe ariko biboneka mubiribwa nkibimera bya alfalfa hamwe namashaza yacitsemo ibice. Coumestans nayo ifite ingaruka zisa na estrogene ariko ntabwo yizwe cyane.

Kwirukana imigani: Ibyavuye mu bushakashatsi

Kanseri ya prostate

Kimwe mu bice bikomeye byubushakashatsi bujyanye n'ingaruka z'ubuzima bwa soya byibanda kuri kanseri ya prostate, kanseri yiganje mu bagabo. Ubushakashatsi bwakozwe mu bihugu bya Aziya, aho soya ikoreshwa cyane, bugaragaza umubare muto wa kanseri ya prostate ugereranije n’ibihugu by’iburengerazuba. Uku kwitegereza gushishikaje kwateye abahanga gucengera cyane isano iri hagati yo gufata soya hamwe na kanseri.

Ubushakashatsi bunini bwerekana ko kunywa soya bifitanye isano no kugabanya 20-30 ku ijana ibyago byo kwandura kanseri ya prostate. Izi ngaruka zo gukingira zitekereza ko zikomoka kuri isoflavone igaragara muri soya, ishobora kubangamira imikurire ya selile ya kanseri cyangwa ikagira ingaruka ku misemburo ya hormone muburyo bugabanya ibyago bya kanseri. Byongeye kandi, soya isa nkaho igira ingaruka nziza na nyuma ya kanseri ya prostate. Ubushakashatsi bwerekana ko soya ishobora gufasha kudindiza iterambere ry’indwara no kuzamura umusaruro w’abarwayi, bigatanga inyungu zishobora kuba ku basanzwe barwaye kanseri ya prostate.

Kanseri y'ibere

Ibimenyetso bijyanye na kanseri y'ibere no kunywa soya birashimishije. Ubushakashatsi bwinshi bwagiye bwerekana ko gufata soya bifitanye isano no kugabanuka kwa kanseri y'ibere na nyababyeyi. Kurugero, ubushakashatsi bwerekanye ko abagore barya igikombe kimwe cyamata ya soya buri munsi cyangwa buri gihe barya igice cyigikombe cya tofu bafite ibyago 30% byo kwandura kanseri yamabere ugereranije nabarya soya nkeya cyangwa ntayo.

Inyungu zo kurinda soya zizera ko zigaragara cyane iyo zitangijwe hakiri kare mubuzima. Mugihe cyubwangavu, ibice byamabere biratera imbere, kandi guhitamo imirire birashobora kugira ingaruka muriki gihe gikomeye. Nyamara, ibyiza byo kurya soya ntabwo bigarukira kubantu bato. Inyigisho zubuzima bwiza bw'abagore zerekana ko abagore bafite amateka ya kanseri y'ibere binjiza soya mu mirire yabo bishobora kugabanya cyane ibyago byo kwandura kanseri no gupfa. Ibi byerekana ko soya ishobora gutanga inyungu zo gukingira mubice bitandukanye byubuzima, harimo na nyuma yo gusuzuma kanseri.

Ubushakashatsi bwakuyeho umugani uvuga ko kunywa soya byongera ibyago bya kanseri ahubwo bigashyigikira igitekerezo cy'uko soya ishobora kugira uruhare mu kurinda kanseri ya prostate na kanseri y'ibere. Ingaruka zingirakamaro zagaragaye mubushakashatsi bwinshi zishimangira agaciro ko gushyira soya mumirire yuzuye, bishimangira uruhare rwayo nkibiryo biteza imbere ubuzima. Ibimenyetso byerekana ko isoflavone ya soya hamwe nibindi bikoresho bigira uruhare mu kugabanya ibyago bya kanseri ndetse no kurushaho kunoza ingaruka ku bantu barwaye kanseri, bityo soya ikagira uruhare runini mu ngamba z’imirire igamije gukumira no gucunga kanseri.

Ubwumvikane bwa siyansi nibyifuzo

Guhindura mubumenyi bwa siyanse kubyerekeye soya na kanseri bigaragarira mubyifuzo byimirire. Ubushakashatsi bwa Kanseri Ubwongereza ubu bushyigikiye impinduka ebyiri z’imirire zifasha kugabanya ibyago byo kurwara kanseri y'ibere: gusimbuza amavuta y’inyamaswa n’amavuta y’ibimera no kongera gufata isoflavone biva ahantu nka soya, amashaza, n'ibishyimbo. Ubu buyobozi bushingiye ku bimenyetso bigenda byiyongera byerekana ko indyo ishingiye ku bimera ikungahaye kuri ibyo bikoresho ishobora kugira uruhare mu kugabanya ibyago bya kanseri no kuzamura ubuzima.
