Palibe funso kuti matenda a leliac akukwera, komanso mphamvu zowonongeka zowonongeka zingakhale, komanso. Koma kodi tirigu wothira mavitamini-omwe amadziwikanso ndi GMO tirigu-amalakwa?
Ayi, tirigu wosinthidwa bwino sichifukwa choyendayenda m'makutu a laliac ndi a gluten, chifukwa chakuti tirigu GMO sichikulirakulira (komabe).
Kuti ziganizidwe kuti zamoyo zasinthidwa, chomera monga tirigu chiyenera kukhala ndi majeremusi ake omwe asinthidwa kudzera mu majini opanga ma laboratory. Asayansi omwe amapanga mbewu zowonjezera mazira akuyang'ana kuti awonetse khalidwe lofunika mu mbewu imeneyo, ndipo amachita zimenezo mwa kuyika njira yatsopano ya majini ku mtundu wina wa mbeu.
Kodi GMO Imakhala Yotsutsana ndi Chilala?
Mwachitsanzo, chimphona chamakono cha Monsanto Co chinapanga ma soya a GMO mwa kufalitsa ma genetiki kuchokera ku mabakiteriya ena, Agrobacterium sp. Pulogalamu ya CP4, mujeni la soya. Matendawa amathandiza kuti soya zisagwiritsidwe ntchito mobwerezabwereza ndi herbicide Roundup (yomwe imatulutsidwa ndi Monsanto). Pakati pa 80 peresenti ndi 90 peresenti ya soya ku US ndi GMO Roundup Ready soya.
Monsanto, yomwe mu 2004 inasiya ntchito yopanga tirigu Roundup Ready, inati mu 2011 kuti idayesetsanso kuti tirigu amagwiritsa ntchito tirigu pakalipano, kuti apange tizilombo ta tirigu.
Otsutsana-makamaka Syngenta AG ndi BASF Global-akutsatirani tirigu wa GMO.
Panali vuto limodzi lokha la GMO tirigu (Roundup Ready tirigu) omwe adapezeka pa famu ku Oregon kumbuyo kwa 2014. Komabe, palibe mankhwala a tirigu a GMO omwe akugulitsidwa. Ndipo izo zikutanthauza (mosiyana ndi zomwe anthu ambiri amakhulupirira) kuti GMO tirigu sungakhoze kuimbidwa mlandu chifukwa cha kuchuluka kwa milandu yotchedwa celiac ndi gluten .
Tirigu Wosakanizidwa Angakhale Wolakwa, Ngakhale
Izi sizikutanthawuza kuti tirigu sanasinthe pazaka makumi khumi ndi ziwiri zapitazo, komabe-zakhala, chifukwa cha ndondomeko yotchedwa kusakanizidwa. Ndipo asayansi ena (ngakhale kuti si onse) amanena kuti kusintha kumeneku kungakhale chifukwa chimodzi cha kuwonjezeka kwokhoza kulekerera gluten.
Mu hybridization, asayansi samayang'ana molunjika ndi genome ya zomera. Mmalo mwake, amasankha mtundu wina wa chomera chokhala ndi makhalidwe abwino ndipo amawabzala kuti atsimikizire makhalidwe awo. Izi zikachitika mobwerezabwereza, mibadwo yambiri ya zomera zina zimawoneka mosiyana kwambiri ndi makolo awo.
Izi ndi zomwe zachitika ndi tirigu wamakono, womwe ndi wamfupi, wofiira, komanso wapamwamba kwambiri kuposa wokolola tirigu zaka 100 zapitazo. Mbewu za tirigu ndi nyemba za tirigu zimakhala m'malo mwa msuwani wawo wamtali, ndipo mikate ya tirigu imafuna nthawi yocheperapo ndi fetereza kuti ikhale ndi zipatso zambiri za tirigu.
Dr. William Davis, wolemba buku logulidwa bwino kwambiri la tirigu wotchedwa Wheat Belly , amauza mafunso m'buku lake kuti ngati kusintha kumeneku kwa tirigu kwachititsa kuti matendawa akhale okhudzana ndi thanzi, kuphatikizapo kunenepa kwambiri ndi shuga. "Kusintha pang'ono kwa mapuloteni a tirigu kumatha kusiyanitsa pakati pa chitetezo champhamvu cha mthupi ndi mapuloteni a tirigu ngakhale kuti palibe chitetezo cha mthupi," Davis akulemba.
Tirigu wamakono wapangidwa kuti akhale ndi gluten wambiri, iye akuti.
Komabe, kafukufuku wofalitsidwa mu 2013 mu Journal of Agricultural and Food Chemistry akukayikira pa mbali ya lingaliro la Davis pamene linanena kuti palibe gluten yochuluka mu tirigu wamakono kuposa momwe zinaliri mu 1920s-nyengo tirigu.
Kotero Nchiyani Choonadi Chikupitirira?
Izo siziri bwino. Kafukufuku amasonyeza kuwonjezeka kwakukulu kwa chiwerengero cha matenda a leliac kwa zaka makumi angapo zapitazo. Momwemonso, kutchuka kwa gluten kumatulukanso, ngakhale kuti sipanakhalepo phunziro lililonse kuti atsimikizire kuti (ndipo ena amatsutsa zowonongeka za zakudya zopanda chakudya cha gluten kuti ziwonjezeke).
Donald D. Kasarda, sayansi ya zaulimi ku United States yomwe idaphunzitsa maphunziro a 2013 pa tirigu wa tirigu mu 1920, akuti ndikotheka kuti kuwonjezeka kwa tirigu m'zaka zaposachedwa-osati kuwonjezeka kwa gluteni mu tirigu makamaka kudyedwa-kungakhale mbali yowonjezera kuwonjezeka chiwerengero cha matenda a celiac. Amanenanso kuti kugwiritsira ntchito tirigu gluten monga chophatikiza mu zakudya zosakanizidwa kungapereke.
Komabe, palibe amene amadziwa chifukwa chake matenda a mphepo yam'madzi (komanso mphamvu ya gluten) ingawononge anthu ambiri. Pali chinthu chimodzi chokha, ngakhale: tirigu wosinthidwa sungakhale wolakwa.
