Akukho mbuzo ukuba isifo se-celiac senyuka , kwaye ukungavalelwanga kwe- gluten kungabikho, ngokunjalo. Kodwa ingqolowa eguqulwa ngokwemizimba-eyaziwa ngokuba yi-GMO yengqolowa-ityala?
Hayi, ingqolowa eguqulwa ngokwemizimba ayiyikusola iindawo zokunyuka kwi-celiac kunye ne-gluten sensizwa, ngenxa yesizathu esilula ukuba i-GMO ngqolowa ayifumanekanga ngokuthengisa (okwamanje).
Ukuze kuthathelwe ingqalelo ukuguqulwa kwemvelo, isityalo esinjengqolowa sidinga ukuba i-genome yayo ishintshwe ngokusebenzisa i-gene splicing kwi-laboratory. Iingcali zenzululwazi ezivelisa izityalo zifuna ukuvelisa umgangatho onqwenelekayo kuloo sityalo, kwaye zenza njalo ngokufakela ukulandelelana kwezinto ezivela kwezinye iindidi ukuya kwi-genome yesityalo.
I-GMO Isikolo esichasene nesomiso?
Ngokomzekelo, i-biotechnology enkulu i-Monsanto Co. yakha i-soybeans yayo ye-GMO ngokuzisa ukulandelana kwemfuza kwi-bacterium ethile, i-Agrobacterium sp. Inkqubo ye-CP4, kwi-geny's genome. Le bhaktiriya yesifo ivumela ukuba ii soya zixhathise izicelo eziphindaphindiweyo ze-Roundup i-Herbicide (kwakhona iveliswe nguMonsanto). Phakathi kwama-80 ekhulwini kunye ne-90 ekhulwini kwesoya ekhulile e-US yi-GMO Roundup Ready soy.
I-Monsanto, ngo-2004 eyashiye imizamo yokuphuhlisa ingqolowa ye-Roundup Ready, yathi ngo-2011 ukuba iphinda ihlola ubunjineli bemfuyo-ngeli xesha, ukuvelisa intsholongwane engapheliyo yenkomfa kunye neyona ephezulu.
Abakhuphiswano-ngokukodwa, iSyngenta AG kunye ne-BASF Global-nabo bafuna ingqolowa ye-GMO.
Kwakukho ityala elilodwa eliqhelekileyo le-GMO yengqolowa (i-Roundup Ready ngqolowa) efunyenwe epulazini e-Oregon emva ko-2014. Nangona kunjalo, akukho mveliso yeengqolowa ze-GMO ezithengiswayo ngoku. Kwaye oko kuthetha (ngokuchasene nenkolelo eninzi) ukuba i-GMO yengqolowa ayikwazi ukuthethwa ngenxa yeemeko zentlupheko ye- celiac ne- gluten .
Ubungozi obunobungozi bunokuthi bube necala, nangona kunjalo
Oko akuthethi i ngqolowa ayizange ishintshe ngaphezu kwamashumi eminyaka edlulileyo, nangona-injalo, ngenxa yenkqubo ebizwa ngokuba yi-hybrid. Kwaye ezinye iinzululwazi (nangona kungengabo bonke) zithi ezo zinguqu zinokubangela enye yokwanda kokukwazi ukunyamezela i-gluten.
Kwi-hybridization, izazinzulu aziyikucwangcisa ngqo kwi-genome yesityalo. Kunoko, bakhetha imimandla ethile yesityalo kunye neempawu ezinqwenelekayo kwaye bazalise ukuqinisa ezo zimpawu. Xa oku kwenziwa ngokuphindaphindiweyo, izizukulwana ezilandelelanayo zesityalo esithile ziyakwazi ukubonakala zihluke kakhulu kwizitata zezityalo.
Yilokho okwenzekileyo ngqolowa yanamhlanje, emfutshane, i-browner, kwaye iphakame kakhulu kunokuba ivunyiwe ingqolowa kwiminyaka eyi-100 edlulileyo. Izityalo zengqolowa kunye nezityalo ezingqolowa zengqolowa ezithathiweyo zithathele indawo zabo zabazala, kwaye ezi ngxaki zengqolowa zidinga ixesha elincinci kunye nesichumiso esincinci ukuvelisa isivuno esihle seengqolowa.
UDkt. William Davis, umbhali wencwadi yokuthengisa ingqolowa enokuthengiswa kakhulu ngqolowa uBurly Belly , uphakamisa imibuzo kwincwadi yakhe malunga nokuba ngaba utshintsho kwengqolowa bangela ukuba i-spike ibe neengxaki zempilo ezinxulumene ne-gluten, kubandakanya ukukhuluphala kwesifo sikashukela nesifo sikashukela. Utshintsho oluncinci kwisakhiwo seprotheyini yengqolowa lunokuthi lubehluko phakathi kweempendulo ze-immune eziphazamisayo kwiprotheyini yengqolowa ngokungafani nokuphendula kwamagciwane onke, "uDavis ubhala.
Iingqolowa zanamhlanje ziye zaveliswa ukuba zibe ne gluten ngaphezulu, utsho.
Nangona kunjalo, uphando olupapashwe ngo-2013 kwi- Journal of Agricultural and Food Chemistry lucinga ukungathandabuzeki malunga nenxalenye ye-hypothesis ye-Davis xa ibixelele ukuba akakho okona kulona ngqolowa yanamhlanje kunokuba bekukho ngexesha likama-1920-ngqolowa.
Ngoko Yintoni Eyinyani Ukuqhubeka?
Akucaci. Izifundo zibonisa ukwanda okwenziwe kwiziganeko zesifo se-celiac kwiminyaka emininzi edlulileyo. Ngokwe-anecdotally, ububele be-gluten buya kukhula, nangona akuzange kubekho naluphi na uphando lokuqinisekisa ukuba (kwaye abanye basolisa ukunyameka kwamanje kokutya okungekho gluten ukwenyuka kwenyuka).
UDonald D. Kasarda, isazi senzululwazi yeSebe lezoLimo lase-United States, owabhala umbango we-2013 ngo-1920, uthi kunokwenzeka ukuba ukwandiswa kokutya kwengqolowa kwiminyaka yakutshanje-kunokuba ukwanda kwe-gluten kwingqolowa idliwe-kunokuthi ube yinxalenye yokubeka ityala lokunyuka iziganeko zesifo esiqwengileyo. Kwakhona uthi ukusetyenziswa kwengqolowa gluten njengesithako ekutya okucutshungulwayo kunokuncedisa.
Nangona kunjalo, akukho mntu uyazi ukuba kutheni isifo se-celiac (kwaye mhlawumbi ubuninzi be-gluten) sinokuchaphazela abantu abaninzi. Kukho into eqinisekileyo, nangona kunjalo: Ingqolowa eguqulwayo igugu ayikwazi ukubeka ityala.
