Soya imaze igihe kinini yizihizwa nkisoko ya poroteyine itandukanye kandi ifite intungamubiri ku isi. Yishimiye muburyo butandukanye, kuva tofu na tempeh kugeza amata ya soya na edamame, iyi proteine ​​ishingiye ku bimera yuzuyemo intungamubiri za ngombwa nka poroteyine, fer, amavuta ya omega-3, fibre, na calcium. Nubwo ikunzwe cyane ninyungu nyinshi zubuzima, soya yagiye yibasirwa nibitekerezo bitandukanye, cyane cyane kubyerekeye ingaruka zayo kubagabo. Iyi ngingo igamije guca intege iyi migani no kwerekana uburyo kwinjiza soya mu ndyo yawe bishobora gushyigikira ubuzima rusange n'imibereho myiza.

Ubushobozi bwo Kwubaka Imitsi ya Soya

Umugani wamamaye cyane ni uko poroteyine ya soya igabanuka ugereranije na poroteyine zishingiye ku nyamaswa nka whey cyangwa casein mugihe cyo kubaka imitsi. Iyi myizerere yarakomeje nubwo ibimenyetso bigenda byiyongera ukundi. Ubushakashatsi buherutse guhangana n’iki gitekerezo cyataye igihe, byerekana ko poroteyine ya soya ishobora gukora neza nka bagenzi bayo bashingiye ku nyamaswa kugira ngo imitsi ikure n'imbaraga.

Isesengura ryingenzi rya meta-isesengura ryasohotse mu kinyamakuru mpuzamahanga cy’imirire ya siporo n’imikino ngororamubiri itanga urumuri kuri iki kibazo. Ubushakashatsi bwasuzumye ibigeragezo bitandukanye ugereranya ingaruka za poroteyine ya soya na poroteyine y’inyamaswa mu rwego rwo guhugura. Ibyavuye mu bushakashatsi byagaragaje neza: poroteyine ya soya yagaragaye ko ikora neza nka poroteyine y’inyamaswa mu kongera imitsi n'imbaraga. Abitabiriye amahugurwa bitabiriye imyitozo yo kurwanya no kurya inyongera ya soya ya soya bafite uburambe bwiyongera mubunini bwimitsi n'imbaraga ugereranije nabiyongereyeho ibizunguzungu cyangwa casein.

Ibi bimenyetso birashimishije cyane cyane kubagabo bakurikiza ibiryo bikomoka ku bimera cyangwa ibikomoka ku bimera. Kubantu bashingira kumasoko ashingiye kuri proteine, soya itanga inyungu zifatika zitagomba kwirengagizwa. Ntabwo poroteyine ya soya ishyigikira iterambere ryimitsi gusa, ahubwo inatanga ubundi buryo bwagaciro kubantu bahitamo kwirinda ibikomoka ku nyamaswa. Kwinjiza poroteyine ya soya mumirire yawe nyuma yimyitozo ngororamubiri irashobora gufasha kugera ku ntego zo kwinezeza no kugira uruhare muri rusange kubaka imitsi.

Byongeye kandi, poroteyine ya soya irashobora guterwa nubwiza bwayo bwiza bwa aside amine. Soya irimo aside amine yose yingenzi ikenewe mugusana imitsi no gukura, bigatuma isoko ya proteine ​​yuzuye. Ubu bwiza, bufatanije nubushobozi bwabwo bwo gutera intungamubiri za poroteyine imitsi kimwe na poroteyine zishingiye ku nyamaswa, bishimangira ubushobozi bwa soya nk'uburyo bukomeye bwo kubaka imitsi.

Muri make, proteyine ya soya ntiri kure cyane yo guhitamo imitsi. Ubushakashatsi buherutse kwerekana bwerekana akamaro kabwo, bwerekana ko bushobora guhangana na poroteyine zishingiye ku nyamaswa mu kuzamura imikurire n'imbaraga. Waba uri ibikomoka ku bimera, ibikomoka ku bimera, cyangwa ushaka gusa gutandukanya poroteyine zawe, poroteyine ya soya igaragara nkigice gikomeye kandi cyiza cyimirire yubaka imitsi.

Gukemura ibibazo bijyanye n'ingaruka za Hormonal

Ikibazo gikunze kugaragara ku kunywa soya ni ingaruka zishobora kugira ku buringanire bwa hormone, cyane cyane urugero rwa estrogene na testosterone ku bagabo. Bamwe bahangayikishijwe nuko kunywa soya bishobora kuzamura urugero rwa estrogene cyangwa testosterone yo hasi, ahanini bitewe nuko isoflavone iba muri soya - ibimera biva mu bimera bishobora kwigana estrogene. Ariko, ikigaragara ni uko kunywa soya mu rugero bitagira ingaruka cyane kuri testosterone cyangwa estrogene.

Urujijo kuri soya na hormone akenshi bituruka kuri raporo nkeya zitaruye zerekeye abagabo bakuze banywa soya nyinshi cyane - bikubye inshuro icyenda gufata isoflavone. Izi manza zavuze ko zahinduye imisemburo, ariko ni ngombwa kumenya ko abo bantu banywa soya nyinshi kandi bahura nintungamubiri. Ibyo kurya bikabije ntabwo byerekana uburyo bwimirire busanzwe kandi ntibigaragaza ingaruka zo gufata soya mu rugero.

Ubushakashatsi bwa siyansi ku baturage muri rusange bwerekana ko kunywa soya mu rwego rwo kurya indyo yuzuye bitagira ingaruka mbi ku rwego rwa hormone. Ubushakashatsi bwimbitse bwerekanye ko urwego rusanzwe rwo gukoresha soya nta ngaruka zikomeye rufite kuri testosterone cyangwa estrogene ku bagabo. Kurugero, ubushakashatsi bwimbitse bwubushakashatsi bwerekana ingaruka za soya kumisemburo yabagabo bwanzuye ko kunywa soya bisanzwe bidahindura urugero rwa testosterone cyangwa ngo byongere urugero rwa estrogene kubagabo.

Birakwiye kandi kumenya ko soya atariyo yonyine igira ingaruka kumagara ya hormone. Indyo yuzuye, imibereho muri rusange, hamwe ningirabuzima fatizo bigira uruhare runini muburinganire bwa hormone. Nkibyo, kwinjiza urugero rwa soya mu ndyo yuzuye ntabwo bishoboka guhungabanya imisemburo ya hormone.

Muri make, mugihe impungenge zijyanye na soya na hormone bikomeje, ibimenyetso bishyigikira ko kunywa soya bitagereranywa cyane na testosterone cyangwa estrogene kubagabo. Indwara zitandukanijwe zimpinduka ziterwa na hormone zajyanye no gufata soya ikabije hamwe nintungamubiri, ntabwo bisanzwe mubikorwa byimirire. Kubwibyo, kubagabo benshi, harimo soya mumirire irashobora gukorwa neza kandi nta ngaruka mbi za hormone.

Kanseri ya Soya na Prostate

Umugani wiganje ni uko kunywa soya bishobora kongera ibyago byo kurwara kanseri ya prostate, ariko ubushakashatsi burigihe buvuguruza iki gitekerezo. Mubyukuri, ibimenyetso byerekana ko soya ishobora gutanga inyungu zo kwirinda ubu bwoko bwa kanseri, iyi ikaba ari kanseri ya kabiri ikunze kugaragara ku bagabo ku isi. Ubushakashatsi butandukanye bwerekanye ubushobozi bwa soya kugirango igabanye ibyago byo kurwara kanseri ya prostate, irwanya imyumvire itari yo ku ngaruka zayo.

Ubushakashatsi bwakozwe ku bushakashatsi 30 bwakozwe bwerekanye isano iri hagati yimirire ya soya nyinshi ndetse no kugabanya kanseri ya prostate. Iri sesengura ryakozwe ryatanze ibimenyetso bifatika byerekana ko indyo ikungahaye kuri soya ifitanye isano no kwandura kanseri ya prostate. Ingaruka zo gukingira soya zitekereza ko zikomoka kubintu byinshi birimo isoflavone, byagaragaye ko bifite imiti irwanya kanseri.

Igitekerezo kivuga ko soya ishobora kugabanya ibyago bya kanseri ya prostate byatewe ahanini n’ubushakashatsi bwakozwe na epidemiologi bwaturutse mu bihugu bya Aziya, aho soya ikoreshwa cyane ugereranije no mu bihugu by’iburengerazuba. Kurugero, umubare wa kanseri ya prostate mu Buyapani, Koreya, n'Ubushinwa uri hasi cyane ugereranije na Amerika. Mu Buyapani, umubare w'abanduye ni 26,6 ku bagabo 100.000, mu gihe muri Koreya no mu Bushinwa, ibipimo ni 22.4 na 12.0 ku bagabo 100.000. Ibinyuranye na byo, kanseri ya prostate muri Amerika iri hejuru cyane, aho 178.8 ku bagabo 100.000 mu baturage b'Abirabura na 112.3 ku 100.000 mu bazungu batari Hisipaniya.

Ibi byagaragaye ko itandukaniro riri hagati y’ibipimo bya kanseri ya prostate byatumye abahanga mu bya siyansi bashakisha ingaruka zishobora gukingira kunywa soya. Ubushakashatsi bwerekana ko urugero rwa soya rwinshi muri ibi bihugu rushobora kugira uruhare mu kugabanya impfu za kanseri ya prostate ndetse n’impanuka. Isoflavone muri soya bemeza ko igira ingaruka nziza kubuzima bwa prostate muguhindura imisemburo ya hormone no kwerekana imiti igabanya ubukana na antioxydeant.

Muri make, igitekerezo kivuga ko soya yongera kanseri ya prostate ntabwo ishyigikiwe nubushakashatsi buriho. Ibinyuranye nibyo, ibimenyetso byerekana ko kwinjiza soya mu ndyo yawe bishobora kugabanya ibyago byo kurwara kanseri ya prostate. Hamwe nibimenyetso bigenda byiyongera bishyigikira inyungu zayo zo kubirinda, soya irashobora kuba inyongera yingirakamaro kumirire igamije guteza imbere ubuzima muri rusange no kugabanya ibyago bya kanseri.
