P: Na ke lokela ho qoba ho itšehla thajana ka protheine ea soya?

K: Soy e se e le taba e nang le likhang ebile e le thata. Ho latela nalane ea baahi ba Asia ba ne ba jele lihlahisoa tse ngata tsa soya ha ba ntse ba phela nako e telele le e phetseng hantle lefatšeng. Patlisiso mabapi le protheine ea soya le bophelo bo botle ba methapo ea pelo e ile ea ba matla hoo e ileng ea fuoa tumello ea bophelo bo botle, e lumellang lik'hamphani tsa lijo ho bolela hore "ligrama tse 25 tsa protheine ea soya ka letsatsi, e le karolo ea lijo tse se nang mafura a mangata le k'holeseterole, li ka fokotsa kotsi ea lefu la pelo. Ho sebelisoa ha (lebitso la lijo) ho fana ka ligrama tsa X tsa protheine ea soya. "

Empa molemong o mong le o mong oa bophelo bo botle ba semela sena se felletseng sa limela, o tla utloa ka litlamorao tse ka bang teng, ho kenyeletsoa kotsi ea kankere e itseng, pherekano ea lihormone e senyehileng, tšitiso ea tšebetso ea qoqotho, kapa ho noa meriana e bolaeang likokonyana le chefo.

E fokotsa mathata a mang, Agency for Healthcare Research and Quality (AHRQ) e phatlalalitse tlaleho e maqephe a ka bang 400 mabapi le litlamorao tsa soya le soya isoflavones (li-antioxidants tse fumanoang ka soya), ka ho etsa qeto ea hore, "Bakeng sa liphetho tsohle, ho kenyeletsoa le liketsahalo tse mpe, ho na le ha ho na bopaki bo tiileng ba phello ea karabelo ea tekanyetso bakeng sa protheine ea soya kapa isoflavone. " Leha ho le joalo, hobane lihlahisoa tsa soya li hlaha ka mefuta e fapaneng haholo ea soya, soya e belisitsoeng, protheine ea soya e itšehla thajana, mme pherekano e ngoe e ntse e tsoela pele ho latela.

Ho itšehla thajana ha protheine ea soy haholo-holo ho kentsoe ka tlas'a microscope ea bophelo bo botle mabapi le polokeho ea eona, ka lebaka la ts'ebeliso e atileng ea ho eketsa protheine ea lijo tse fapaneng kapa ho ntlafatsa sebopeho. Ho na le lintho tse tharo tse tloaelehileng tseo u lokelang ho li ela hloko.

1. Tšilafalo ea tšepe. Soy protein isolate e ntšoa ho phofo ea soya e senyehileng. E entsoe ka protheine e batlang e hloekile, hobane ts'ebetso ea ho itšehla thajana e hlahisa sehlahisoa se liprotheine tse etsang liperesente tse 93 ho isa ho tse 97, se siea mafura le lik'habohaedreite tse fokolang. Matšoenyeho mabapi le ts'ebetso ea ho itšehla thajana a bakoa ke taba ea hore aluminium e fumanoeng ka har'a likhalase tse kholo tse sebelisetsoang ho arola protheine ea soya e kanna ea kenella ka har'a protheine ka boeona, mme ea eketsa menyetla ea chefo ea morethetho o matla. Sena ke se inahaneloang ka ho felletseng, kaha ha ke so bone tlhahlobo ea soya, whey, kapa protheine efe kapa efe e ikhethileng e bonts'ang tšilafalo ea tšepe e boima ho tsoa lijaneng tse sebelisitsoeng nakong ea ho itšehla thajana.

2. Kotsi ea chefo e bolaeang likokoanyana. Liphesente tse mashome a robong tsa soya e fetotsoeng ka liphatsa tsa lefutso ha e hanyetsane le glyphosate, chefo e bolaeang likokoanyana e fumanehang ho Round Up. Matšoenyeho a hlahisitsoeng mabapi le ho ja lihlahisoa tse nang le protheine ea soya e arohaneng ke hore o tla sebelisa lik'hemik'hale tsena tse ngata haholo. Litaba tse monate? Glyphosate ha e monoe hantle ke pampitšana ea GI ea motho, litlamorao tse mpe tse ka bang teng ho batho li itšetlehile ka tekanyetso, 'me boemo ba lethal dose bo baka likhang haholo.

Litaba tse ling tse monate (kapa mohlomong litaba tse mpe) ke hore ha ho tluoa ho glyphosate, protheine ea soya itšehla hase bothata ba hau bo boholo. Glyphosate e hohle, e leng litaba tse mpe haholo! E tšoana le BPA, eo ke neng ke e koahetse pele. Lipatlisiso li phatlalalitsoe ka 2014 ka Khemistri ea Lijo le Tikoloho & Analytical Toxicology e totobalitse taba ea hore ts'ebeliso ea lefats'e ea glyphosate e entse hore e be ngata tikolohong ea rona e haufi le phepelong ea lijo. Le ha palo ea glyphosate tšebelisong ea protheine ea soya e sa tsejoe, ha ho na monyetla oa hore ke soya ea hau ea mantlha, feela, kapa esita le mohloli o moholo oa tlhahiso ea seoa sena se bolaeang likokonyana.

3. Li-isoflavone tse tsitsitseng. E 'ngoe ea libaka tse nang le likhang ka ho fetisisa tsa soya, li-isoflavone ke li-antioxidants tse tummeng ka ho etsisa estrogen' meleng. Phello ena e 'nile ea nkoa e le molemo, ka lipatlisiso tse bontšang hore 75 kapa 54 milligrams ka letsatsi (mg / d) ea soy isoflavones e ka eketsa masapo a masapo le ho fokotsa makhetlo a mangata le ho teba ha mahlaseli a chesang, ka ho latellana. Leha ho le joalo, li-isoflavones tse soya le tsona li hlahisitsoe ho bapala karolo ea ho eketsa kotsi ea mofetše oa matsoele. Lipatlisiso sebakeng sena li rarahane ebile li lula li fetoha, ka liphello tse mpe tse bonoang lithutong tsa liphoofolo, empa ha ho liphello tse fumanoang lithutong tsa batho.

Hape ke habohlokoa ho hlokomela hore ho itšehla thajana ha protheine ea soya ha se mohloli oa li-isoflavone.Ho ea ka USDA Isoflavone Database, ounce e le 'ngoe (hoo e ka bang scoop) ea soy protein isolate e na le 28mg soy isoflavones le li-ounces tse tharo tsa tofu e phehiloeng li na le 23mg soy isoflavones. Motheong oa ho sebeletsa, lijo tsena ka bobeli li na le tekanyo e lekanang ea li-isoflavone, empa protheine ea soya e itšehla thajana e na le liprotheine tse ngata haholo: 23g vs. 8g.

Lintho tsohle tse nkuoeng, ho itšehla thajana ka bongata ba protheine ea soya ha ho fane ka kotsi ea bophelo bo botle. Ke bona molemo o moholo oa protheine ea soya e le sesebelisoa sa phepo e nepahetseng ho u thusa ho fihlela litlhoko tsa hau tsa letsatsi le letsatsi tsa protheine. Haeba u qoba ho ja protheine ea lebese (whey) hang ka mor'a ho ikoetlisa kapa haeba u hloka ho eketsa protheine lijong tse fanoeng, sebelisa protheine ea soya joalo ka ha u ne u ka sebelisa tlatsetso efe kapa efe ea protheine.
