Umbuzo: Ingabe kufanele ngigweme ukuhlukanisa amaprotheni e-soy?

A: USoy usephenduke isihloko esinempikiswano futhi esiyinkimbinkimbi. Ngokomlando abantu base-Asia basebenzise inqwaba yemikhiqizo yesoya ngenkathi futhi bephila impilo ende futhi enempilo emhlabeni. Ucwaningo olumayelana namaprotheni e-soy kanye nempilo yenhliziyo nemithambo yegazi lwaba namandla kangangokuba lwanikezwa isimangalo sezempilo, okuvumela izinkampani zokudla ukuthi zisho ukuthi "amagremu angama-25 weprotheyini yesoya ngosuku, njengengxenye yokudla okuphansi kwamafutha agcwele kanye ne-cholesterol, anganciphisa ubungozi bokudla." isifo senhliziyo. Ukuphakelwa (kwegama lokudla) kunikeza i-X gram yamaprotheni wesoya. "

Kodwa ngazo zonke izinzuzo zezempilo zalo mthombo ophelele wamaprotheni asekelwe ezitshalweni, uzophinde uzwe ngomthelela ongase ube yingozi, okuhlanganisa ukwanda kwengozi yomdlavuza othile, ukulinganisela kwamahomoni aphazamisekile, ukuphazamisa ukusebenza kwegilo, noma ukudla izibulala-zinambuzane nobuthi.

Ukunciphisa okunye ukukhathazeka, i-Agency for Healthcare Research and Quality (AHRQ) ikhiphe umbiko onamakhasi acishe abe ngu-400 ngemiphumela ye-soy kanye ne-soy isoflavones (ama-antioxidants atholakala kusoya), yaphetha ngokuthi, "Kuyo yonke imiphumela, kufaka phakathi imicimbi emibi, kukhona abukho ubufakazi obuqand 'ikhanda bomphumela wokuphendula ngomthamo weprotheni yesoya noma i-isoflavone. " Kodwa-ke, ngoba imikhiqizo yesoya inezinhlayiya ezahlukahlukene ezinhlobonhlobo, isoya evutshiwe, amaprotheni wesoya ahlukanisa, nokunye-ukudideka kuyaqhubeka nokulandela.

I-soy protein isolate ikakhulukazi ibekwe ngokuya ngokuya ngaphansi kwesibonakhulu sezempilo mayelana nokuphepha kwayo, ngenxa yokusetshenziswa kwayo kabanzi ukukhulisa okuqukethwe kwamaprotheni okudla okuhlukahlukene noma ukuthuthukisa ukuthungwa. Kunokukhathazeka okuthathu okuvamile okufanele ukuqaphele.

1. Ukungcola kwensimbi. Ukuhlukaniswa kweprotheni ye-Soy kukhishwa kufulawa osoyiziwe. Yenziwe cishe ngamaprotheni ahlanzekile, njengoba inqubo yokuhlukaniswa ikhiqiza umkhiqizo ongamaphesenti angama-93 kuya kwangu-97, okushiya amafutha nama-carbohydrate amancane. Ukukhathazeka mayelana nenqubo yokuzihlukanisa kugxile eqinisweni lokuthi i-aluminium etholakala emigodini emikhulu esetshenziselwa ukuhlukanisa iphrotheni yesoya ingase ingene kumaprotheni ngokwawo, okwandisa amathuba okuba noshevu we-heavy-metal. Lokhu kuyaqagela ngokuphelele, njengoba ngisazokubona ukuhlaziywa kwe-soy, whey, noma iyiphi i-protein isolate ekhombisa ukungcoliswa kwensimbi esindayo ezitsheni ezisetshenziswa ngesikhathi sokuhlukaniswa.

2. Ingozi yezibulala-zinambuzane. Amaphesenti angama-90 kasoya oshintshwe izakhi zofuzo amelana ne-glyphosate, isibulala-zinambuzane esitholakala eRound Up. Ukukhathazeka okuphakanyiswe mayelana nokudla imikhiqizo ene-soy protein isolate ukuthi uzodla amanani eqile laleli khemikhali. Izindaba ezimnandi? I-Glyphosate ayimuncwe kahle ipheshana le-GI yomuntu, imiphumela engemihle engaba khona kubantu incike kumthamo, futhi izinga lalowo mthamo liyimpikiswano kakhulu.

Ezinye izindaba ezinhle (noma mhlawumbe izindaba ezimbi) ukuthi uma kukhulunywa nge-glyphosate, ukuhlukaniswa kwamaprotheni we-soy akuyona inkinga yakho enkulu. I-Glyphosate ikhona yonke indawo, okuyizindaba ezimbi ngempela! Ifana ne-BPA, ebengiyimbozile phambilini. Ucwaningo lushicilelwe ngo-2014 ku I-Chemistry Yokudla futhi I-Environmental & Analytical Toxicology kuqhakambise iqiniso lokuthi ukusetshenziswa komhlaba wonke kwe-glyphosate kukwenze kwaba kuningi endaweni yethu eseduze nasekuphakelweni kokudla. Yize inani le-glyphosate ekusetshenzisweni kwe-soy protein isolate lingalinganiswanga, mancane amathuba okuthi isoya iyinhloko yakho, kuphela, noma iwumthombo obalulekile wokuchayeka kwalesi sibulala-zinambuzane.

3. Ama-isoflavones agxile. Enye yezindawo eziphikisana kakhulu zesoya, ama-isoflavone ama-antioxidants adume ngokulingisa i-estrogen emzimbeni. Lo mphumela ubonwe njengenzuzo, ngocwaningo olukhombisa ukuthi ama-milligram angama-75 noma angama-54 ngosuku (mg / d) wama-soy isoflavones angakhuphula ubukhulu bamaminerali amathambo futhi anciphise imvamisa nobukhulu bokukhanya okushisayo, ngokulandelana. Kodwa-ke, ama-isoflavones ku-soy nawo ahlongoziwe ukuthi adlale indima ekwandiseni ubungozi bomdlavuza webele. Ucwaningo kule ndawo luyinkimbinkimbi futhi luvela njalo, nemiphumela emibi ebonwe ezifundweni zezilwane, kepha akukho miphumela etholakala ezifundweni zabantu.

Kubalulekile futhi ukuqaphela ukuthi ukuhlukaniswa kwamaprotheni we-soy akuyona imithombo egxilile yama-isoflavones.Ngokusho kwe-USDA Isoflavone Database, i-ounce eyodwa (cishe isikophu esisodwa) se-soy protein isolate iqukethe ama-soy isoflavone angama-28mg kanye nama-ounces amathathu e-tofu ephekiwe aqukethe ama-23mg we-soy isoflavones. Ngokwesisekelo sokuphakelwa, kokubili ukudla kuqukethe cishe umthamo ofanayo we-isoflavones, kodwa i-soy protein isolate iqukethe amaprotheni amaningi kakhulu: 23g vs. 8g.

Zonke izinto ezicatshangwayo, ukudla amanani alinganiselayo wehlukanise amaprotheni we-soy akunikezi ingozi yezempilo. Ngibona inzuzo enkulu yamaprotheni we-soy ahlukanisa njengethuluzi lokudla okunempilo ukukusiza uhlangabezane nezidingo zakho zansuku zonke zamaprotheni. Uma uyeka ukudla amaprotheni obisi (whey) ngemva nje kokujima noma uma udinga ukwandisa amaprotheni ekudleni okunikeziwe, sebenzisa amaprotheni e-soy njengoba ungasebenzisa noma yisiphi isithasiselo samaprotheni.
