Izinto ezi-5 obungazazi malunga nokutya kwe-GMO

Umxholo

• Uphengululo lwe

Nokuba uyayiqonda okanye awuyiqondi, kukho ithuba elihle lokuba utye izinto eziphilayo eziguqulwe ngokwemfuza (okanye ii-GMOs) yonke imihla. Umbutho woMvelisi weGrocery uqikelela ukuba iipesenti ezingama-70 ukuya kwezingama-80 zokutya kwethu zinezithako eziguqulwe ngokwemfuza.

Kodwa oku kutya okuqhelekileyo kuye kwaba sisihloko seengxoxo ezininzi zamva nje: Nge-Epreli nje, uChipotle wenza iintloko xa babhengeza ukuba ukutya kwabo kwenziwa ngazo zonke izinto ezingezo-GMO. Nangona kunjalo, isimangalo esitsha sokwenza iklasi esifakwe eCalifornia ngo-Agasti 28 sicebisa ukuba amabango e-Chipotle awabeki bunzima kuba ikhonkco linika inyama kunye neemveliso zobisi ezivela kwizilwanyana ezondla ii-GMOs kunye neziselo ezinesiraphu yengqolowa ye-GMO, ezinje ngeCoca-Cola.

Kutheni le nto abantu bephakamile ngezixhobo malunga nee-GMO? Siphakamisa isiciko ekutyeni okuphikisanayo. (Fumanisa: Ngaba zezi ziGMO ezintsha?)

1. Isizathu Sokuba Zikho

Ngaba uyazi ngokwenene? "Ngokubanzi, siyazi ukuba ulwazi lwabathengi lwe-GMO luphantsi," utshilo uShahla Wunderlich, Ph.D., unjingalwazi kwezempilo kunye nesayensi yesondlo kwiYunivesithi yaseMontclair State efunda iinkqubo zemveliso yezolimo. Nantsi i-scoop: I-GMO yenzelwe ukuba neempawu ezingazukuvela ngokwendalo (kwiimeko ezininzi, ukumelana nokubulala ukhula kunye / okanye ukuvelisa izinambuzane). Zininzi iimveliso eziguqulweyo zemfuza phaya-i-insulin yokwenziwa esetyenziselwa ukunyanga abaguli abanesifo seswekile ngumzekelo omnye.

Nangona kunjalo, ii-GMO zidume kakhulu ekutyeni. Thatha i-Roundup Ready Corn, umzekelo. Utshintshiwe ukuze usinde ekuboneni iyeza lokubulala ukhula olujikelezileyo. Umbona, iimbotyi zesoya, kunye nomqhaphu zezona zixhaphakileyo izityalo ezitshintshwe ngokwemfuza-ewe, siyayitya ikotoni kwioyile yekotoni. Zininzi ezinye, nangona kunjalo, njengecanola, iitapile, ialfalfa, kunye neswekile beet. (Jonga uluhlu olupheleleyo lwezityalo ezigqithise i-USDA's muster ukususela ngo-1995.) Ekubeni uninzi lwezo zidlo zisetyenziselwa ukwenza izithako, njengeoli yeembotyi zesoya okanye iswekile okanye i-cornstarch, amandla abo okungena ekuboneleleni kokutya makhulu. Iinkampani ezenza ii-GMOs zikholisa ukuxoxa ukuba lishishini eliyimfuneko-ukuba ukondla abantu abakhulayo behlabathi, kufuneka sisebenzise kakhulu umhlaba weefama esinawo, utshilo uWunderlich. "Mhlawumbi ungavelisa ngakumbi, kodwa siziva ngathi kufuneka bajonge ezinye iindlela," utshilo uWunderlich. (PS Ezi zithako zi-7 zikuphanga izondlo.)

2. Nokuba bakhuselekile na

Ukutya okuguqulwe ngokwemfuza kubethe iishelufa zevenkile enkulu ngeminyaka yee-'90s. Nangona oko kubonakala ngathi kudala-ngapha koko, i-nostalgia yeshumi leminyaka isebenza ngokupheleleyo-khange kube kudala ukuba izazinzulu zibone ngokuqinisekileyo ukuba ngaba ukutya ii-GMO kukhuselekile. Kukho izinto ezimbalwa ezithethwa ngabantu, nangona kungekho bungqina beepesenti ezili-100, utshilo uWunderlich. "Enye into kukuba kukho amathuba okuba ii-GMO zinokubangela ukungazwani kwabanye abantu; enye kukuba inokubangela umhlaza." Uphando olungakumbi luyafuneka, utshilo uWunderlich. Uninzi lwezifundo ziqhutywa kwizilwanyana, hayi ebantwini, zondliwe izityalo eziguqulweyo, kwaye iziphumo bezingqubana. Olunye uphononongo olunempikiswano olwapapashwa ngo-2012 ngabaphandi baseFransi bacebisa ukuba olunye uhlobo lombona we-GMO lubangele amathumba kwiimpuku. Olu phando lwapapashwa kamva ngabahleli bejenali yokuqala eyapapashwa kuyo, Ukutya kunye ne-Chemical Toxicology, ukuyikhankanya njengengahambelani nangona uphando belungekho ubuqhetseba okanye ukumelwa gwenxa kwedatha.

3. Zifumaneka phi

Skena iishelufa kwivenkile enkulu oyithandayo, kwaye uya kubona ezinye iimveliso ezibonisa iSitywina esiQinisekisiweyo seProjekthi engeyiyo ye-GMO. (Jonga uluhlu olupheleleyo.) IProjekthi engeyiyo ye-GMO liqela elizimeleyo eliqinisekisa ukuba iimveliso ezinophawu lwayo azinazithako eziguqulwe ngokwemfuza. Nantoni na ephethe ilebheli ye-USDA yeOrganic nayo ayinasimahla i-GMO. Nangona kunjalo, awuyi kubona iilebhile ezichaseneyo zityhila apho zi izithako eziguqulwe ngokwemfuza ngaphakathi. Abanye abantu bafuna ukutshintsha loo nto: Ngo-2014, iVermont yapasisa umthetho ophawula i-GMO ocwangciselwe ukuqala ngoJulayi ka-2016-kwaye kungoku nje kungumbindi wenkundla. Okwangoku, i-US House of Representatives iphumelele i-bill ngoJulayi eya kuvumela, kodwa ayifuni, iinkampani ukuba zibhale izithako eziguqulwe ngofuzo kwiimveliso zazo. Ukuba ipasiswe yiNdlu yeeNgwevu kwaye yasayinwa yangumthetho, iya kuthi ixilonge nayiphi na imithetho yelizwe-ebulala iinzame zeVermont zokufuna iilebheli ze-GMO. (Okusizisa ku: Yintoni Ebaluleke Kakhulu kwiLeyibhile yeSondlo (Ngaphandle kweeCalories).

Ukungabikho kwelebheli, nabani na ofuna ukunqanda ii-GMOs ujongene nedabi: "Kunzima kakhulu ukuthintela ngokupheleleyo kuba igcwele," utshilo uWunderlich. Enye yeendlela zokunciphisa amathuba akho okutya ukutya okuguqulwe ngemfuza kukuthenga imveliso ekhuliswe ekuhlaleni kwiifama ezikwinqanaba elincinci, ezizezona ziphilayo, utshilo uWunderlich. Iifama ezinkulu zinokukhula ngakumbi ii-GMOs, utshilo. Ngaphezu koko, ukutya okukhuliswe ekuhlaleni kudla ngokuba nesondlo ngakumbi kuba kuthathwa xa sele kuvuthiwe, kukunika ixesha lokuphuhlisa izinto ezilungileyo njenge-antioxidants. Iinkomo kunye neminye imfuyo inokutyiswa ukutya kwe-GMO-ukuba ufuna ukuyiphepha loo nto, khangela inyama yendalo okanye ingca.

4. Yintoni eyenziwa ngamanye amazwe malunga nabo

Nantsi imeko apho iMelika isemva kwegophe: Izinto eziguqulweyo zemfuza zibhalwe kumazwe angama-64. Umzekelo, i-European Union (i-EU) ibineemfuno zokuphawula i-GMO ngaphezulu kweshumi leminyaka. Xa kuziwa kwi-GMOs, la mazwe "alumke ngakumbi kwaye anemimiselo emininzi," kusho uWunderlich. Xa i-genetically modified ingredient idweliswe kukutya okupakishweyo, kufuneka kwandulelwe amagama athi "i-genetically modified." Ukhetho olulodwa qha? Ukutya okungaphantsi kwe-0.9 yepesenti yomxholo oguqulwe ngokwemfuza. Nangona kunjalo, lo mgaqo-nkqubo awukho ngaphandle kwabagxeki: Kwiphepha lakutshanje elipapashwe kwi Iimpawu kwiBiotechnology, abaphandi basePoland baphikisana ukuba imithetho ye-GMO ye-EU ithintela ukuveliswa kwezolimo.

5. Nokuba baMbi na ngoMhlaba

Ingxoxo enye yokutya okuguqulweyo yemfuza kukuba ngokuvelisa izityalo ezinqabileyo ngokwendalo kwizitshabalalisi zokhula kunye nezitshabalalisi, amafama anokunciphisa ukusebenzisa kwazo izitshabalalisi. Nangona kunjalo, uphononongo olutsha olupapashwe kwi Isayensi yoLawulo lwezinambuzane icebisa ibali elinzima ngakumbi xa kufikwa kwizityalo ezintathu ezaziwa kakhulu eziguqulweyo. Ukusukela oko kwaphuma izivuno ze-GMO, ukusetyenziswa kwaminyaka le kwemichiza yokutshabalalisa ukhula kwehlile umbona, kodwa kwahlala kufana nomqhaphu kwaye kwanda kwiimbotyi zesoya. Ukuthenga ukutya okunezinto eziphilayo kwalapha ekhaya yeyona ndlela iyiyo, utshilo uWunderlich, kuba ukutya okuphilayo kulinywa ngaphandle kwezibulali zinambuzane. Ngapha koko, ukutya okulinywe kwalapha ekhaya akufuneki ukuba kuyiwe kumazwe nakumazwe, ukuthuthwa okufuna amafutha eefosili kwaye kuvelise ungcoliseko.
