Noma ngabe uyakuqaphela noma cha, kunethuba elihle lokuthi udle izinto eziphilayo eziguqulwe (noma ama-GMO) nsuku zonke. I-Grocery Manufacturer's Association ilinganisela ukuthi amaphesenti angama-70 kuya kwangu-80 okudla kwethu aqukethe izithako ezishintshwe izakhi.

Kodwa lokhu kudla okuvamile sekubuye kwaba yisihloko sezimpikiswano eziningi zakamuva: Ngo-Ephreli nje lo, uChipotle waba sematheni ngesikhathi bememezela ukuthi ukudla kwabo kwenziwa ngazo zonke izithako ezingezona eze-GMO. Kodwa-ke, icala elisha elenziwa ngezigaba elifakwe eCalifornia ngo-Agasti 28 lisikisela ukuthi izimangalo zikaChipotle azinaso isisindo ngoba lolu chungechunge lunikeza inyama nemikhiqizo yobisi ezilwaneni ezidlisa ama-GMO kanye neziphuzo ezine-GMO corn syrup, njengeCoca-Cola.

Kungani abantu bexabana kangaka ngama-GMO? Siphakamisa isivalo ekudleni okuyimpikiswano. (Thola: Ingabe Lawa Ama-GMO Amasha?)

1. Kungani Zikhona

Ngabe uyazi ngempela? "Ngokuvamile, siyazi ukuthi ulwazi lwabathengi lwe-GMO luphansi," kusho uShahla Wunderlich, Ph.D., onguprofesa wesayensi yezempilo nokudla eMontclair State University owenza izifundo zezolimo. Nansi ingqikithi: I-GMO yenzelwe ukuthi ibe nezici ebingeke ivele ngokwemvelo (ezikhathini eziningi, ukumelana nemithi yokubulala ukhula kanye/noma ukukhiqiza izibulala-zinambuzane). Kunenqwaba yemikhiqizo eguqulwe izakhi zofuzo ngaphandle lapho-i-insulin yokwenziwa esetshenziselwa ukwelapha iziguli ezinesifo sikashukela empeleni iyisibonelo esisodwa.

Kodwa-ke, ama-GMO adume kakhulu ekudleni. Thatha i-Roundup Ready Corn, ngokwesibonelo. Ishintshiwe ukuze ikwazi ukusinda ekuchayekeni emithini yokubulala ukhula ebulala ukhula oluzungezile. Ummbila, ubhontshisi, nokotini yizitshalo ezivame kakhulu ezishintshwe izakhi zofuzo-yebo, sidla ukotini emafutheni ompondo. Kukhona abanye abaningi, noma kunjalo, njenge-canola, amazambane, i-alfalfa, ne-beet beet. (Bheka uhlu oluphelele lwezitshalo esezidlule i-USDA's muster kusukela ngo-1995.) Njengoba okuningi kwalokho kudla kusetshenziselwa ukwenza izithako, njengamafutha kabhontshisi wesoya noma ushukela noma isitashi sombila, amandla azo okungena ekudleni makhulu. Izinkampani ezenza ama-GMO zivame ukuphikisa ngokuthi kungumsebenzi odingekayo-ukuthi ukondla inani labantu elikhulayo emhlabeni, sidinga ukuwusebenzisa ngokunenzuzo umhlaba wepulazi esinalo, kusho uWunderlich. "Mhlawumbe ungakhiqiza okuningi, kodwa sibona sengathi kufanele bahlole ezinye izindlela," kusho uWunderlich. (P.S. Lezi Zithako Ezi-7 Zikuphuca Umsoco.)

2. Ukuthi Baphephile Yini

Ukudla okushintshwe izakhi zofuzo kushayise amashalofu ezitolo ezinkulu eminyakeni yama-90s. Yize lokho kubonakala njengesikhathi esidlule-ngemuva kwakho konke, i-nostalgia yeminyaka eyishumi isisebenza ngokugcwele-bekungekho isikhathi eside ngokwanele ukuthi ososayensi bakwazi ukuthola ngokuphelele ukuthi ukudla ama-GMO kuphephile yini. "Empeleni kunezinto ezimbalwa ezishiwo abantu, yize kungekho bufakazi obungamaphesenti ayi-100," kusho uWunderlich. "Okunye ukuthi kunamathuba okuthi ama-GMO angadala ukungezwani komzimba nabanye abantu; okunye ukuthi kungadala umdlavuza." Kudingeka ucwaningo olwengeziwe, kusho uWunderlich. Iningi locwaningo lwenziwe ezilwaneni, hhayi abantu, okuphakelwe izitshalo eziguqulwe ngofuzo, futhi imiphumela ibiphikisana. Olunye ucwaningo olwaba nempikiswano olushicilelwe ngo-2012 ngabaphenyi baseFrance lwaphakamisa ukuthi uhlobo olulodwa lommbila we-GMO lwadala izimila kumagundane. Ucwaningo lwaphinde lwashicilelwa abahleli bephephabhuku lokuqala elashicilelwa kulo, I-Food and Chemical Toxicology, ecaphuna njengokungaphelele yize ucwaningo luqukethe ingekho inkohliso noma ukuhlanekezela amaqiniso kwedatha.

3. Ungabatholaphi

Skena amashalofu esitolo sakho esikhulu esiyintandokazi, futhi cishe uzobona imikhiqizo ethile ephakamisa Uphawu Oluqinisekisiwe Lwephrojekthi Okungeyona ye-GMO. (Bheka uhlu oluphelele.) I-Non-GMO Project iyiqembu elizimele eliqinisekisa ukuthi imikhiqizo enelebula layo ayinazo izithako ezishintshwe izakhi. Noma yini ephethe ilebula le-USDA Organic nayo ayinayo i-GMO. Noma kunjalo, ngeke uwabone amalebula ahlukile aveza lokho lapho kukhona izithako eziguqulwe ngofuzo ngaphakathi. Abanye abantu bafuna ukukushintsha lokho: Ngo-2014, iVermont yaphasisa umthetho wokulebula we-GMO owawuhlelelwe ukusebenza ngoJulayi 2016-futhi njengamanje uyisikhungo sempi enkulu yasenkantolo. Khonamanjalo, iNdlu Yabamele yase-U.S. Yadlulisa umthethosivivinywa ngoJulayi ozovumela, kepha ungadingi, izinkampani ukuthi zifake ilebuli yezakhi zofuzo emikhiqizweni yazo. Uma idluliswa yiSenate futhi yasayinwa ibe ngumthetho, izoshaya noma yimiphi imithetho yombuso ebulala imizamo kaVermont yokufuna ilebuli ye-GMO. (Okusiletha ku: Okubaluleke Kakhulu Kwilebula Lezokudla (Ngaphandle KwamaKhalori).)

Uma kungekho ilebula, noma ngubani ofuna ukugwema ama-GMO ubhekana nempi ekhuphukayo: "Kunzima kakhulu ukukugwema ngokuphelele ngoba kusabalele kakhulu," kusho uWunderlich. Enye indlela yokwehlisa amathuba akho okufaka ukudla okushintshwe izakhi zofuzo ukuthenga umkhiqizo otshalwa endaweni kusuka emapulazini amancane, okungokwemvelo, kusho uWunderlich. Amapulazi amakhulu maningi amathuba okuba akhule ngama-GMO, kusho yena. Ngaphezu kwalokho, ukudla okutshalwe endaweni kuvame ukuba nomsoco ngoba kuthathwa lapho sekuvuthiwe, kukunike isikhathi sokuthuthukisa izinto ezinhle njengama-antioxidants. Izinkomo neminye imfuyo kungondliwa ngokudla kwe-GMO-uma ufuna ukukugwema lokho, funa inyama ephilayo noma edliwe ngotshani.

4. Okwenziwa Amanye Amazwe Ngabo

Nasi isimo lapho iMelika ingemuva kwejika: Izinto eziphilayo eziguqulwe ngofuzo zilebulwe emazweni angama-64. Isibonelo, i-European Union (i-EU) inezidingo zokulebula ze-GMO isikhathi esingaphezu kweminyaka eyishumi. Uma kukhulunywa ngama-GMO, lawa mazwe “acophelela kakhulu futhi anemithethonqubo eyengeziwe,” kusho uWunderlich. Lapho isithako esishintshwe izakhi zofuzo sisohlwini lokudla okuhlanganisiwe, kufanele kwandulelwe amagama athi "genetically modified." Okuwukuphela kokuhlukile? Ukudla okungaphansi kwamaphesenti angu-0.9 okuqukethwe okushintshwe izakhi. Kodwa-ke, le nqubomgomo ayikho ngaphandle kwabagxeki: Ephepheni lakamuva elishicilelwe ku- Amathrendi ku-Biotechnology, Abaphenyi basePoland baphikisa ngokuthi imithetho ye-EU ye-GMO iyavimbela emisha kwezolimo.

5. Ukuthi Abalungile Emhlabeni

Impikiswano eyodwa yokudla okushintshwe izakhi zofuzo ukuthi ngokukhiqiza izitshalo ngokwemvelo ezingazwani nabakhi bokhula nezinambuzane, abalimi banganciphisa ukusetshenziswa kwabo kwezibulala-zinambuzane. Nokho, ucwaningo olusha olushicilelwe ku Isayensi Yezokuphathwa Kwezinambuzane iphakamisa indaba eyinkimbinkimbi uma kukhulunywa ngezitshalo ezintathu ezithandwa kakhulu ezakhiweni zofuzo. Selokhu kwaphuma izitshalo ze-GMO, ukusetshenziswa kwaminyaka yonke kwemithi yokubulala ukhula kwehlile kummbila, kodwa kwahlala kunjalo ukotini futhi kwanda kubhontshisi wesoya. Ukuthenga ukudla kwasendaweni, okuphilayo cishe kungukuhamba okunobungane kakhulu, kusho uWunderlich, ngoba ukudla okuphilayo kutshalwa ngaphandle kwezibulala-zinambuzane. Futhi, ukudla okulinywe endaweni akudingeki kudlule emazweni nasezweni, izinto zokuhamba ezidinga izinto zokubasa ezimbiwa phansi futhi zikhiqize ukungcola.
