Ngaba wakha wayibona ibhalwe 'i-GMO-Free' kwiipakethe zokutya xa usiya kwivenkile enkulu? Xa sibona loo nto, sicinga nje, "Hmm... kunjalo ke ezinye ukutya ziyi-GMO? Ngaba oko kuthetha ukuba azilunganga?" Abanye abantu bayoyika kancinci xa besiva igama elithi GMO, kuba abazi kakuhle ukuba liyintoni na. Abanye abantu bacinga ukuba ezi zinto zenziwe elebhu, azinamvelo, kwaye ziyingozi. Ngoko ke, namhlanje siza kuthetha ngezinto ezi zinto ziguqulwe ngokwemfuza, okanye njengoko sonke sizazi, ziyi-GMO, kwaye ziyichaphazela njani impilo yethu.
Yintoni i-GMO ngokulula?
Kulungile, oku akuyonto inzima njengoko unokucinga. Ngamafutshane, ukutya okuguqulwe ngokwemfuza kukutya apho iijini zesityalo, isilwanyana, okanye iintsholongwane ezivela kuko ukutya zitshintshiwe kwilebhu.
Uyakhumbula indlela esasiqhele ukuzalisa ngayo imithi yemango emakhayeni ethu? Sasithatha isebe lomthi wemango elalinencasa emnandi kakhulu size silifake komnye umthi wemango owawungangenwa zizifo. Emva koko sasiza kufumana umthi wemango omtsha owawunezo mpawu zimbini zilungileyo. Yiloo nto eyenzekayo apha, kodwa ngeteknoloji ephucukileyo kakhulu.
Oko okwenziwa zizazinzulu apha kukufumana ijini kwi -DNA yesidalwa (oko kukuthi, inxalenye equlethe umzobo opheleleyo weso sidalwa) enxulumene nophawu oluthile abalufunayo. Khawuthelekelele ukuba kukho isityalo esingenakutshatyalaliswa zizinambuzane. Izazinzulu zithatha kuphela ijini exhathisayo kweso sidalwa kwisityalo zize ziyifake kwisityalo esifana nombona esiwutyalayo. Emva koko eso sityalo sitsha sombona sikhula sinamandla okumelana nezo zinambuzane. Le teknoloji ibizwa ngokuba yi-genetic engineering.
Into ebalulekileyo kukuba oku kwenziwa ngenjongo ethile eluncedo. Oko kukuthi, akupheleli nje ekutshintsheni izityalo.
Kutheni sitshintsha ukutya ngale ndlela?
Kukho izizathu ezininzi eziphambili zoku. Konke oku kwenzelwa ukwenza imveliso yethu yokutya ibe lula kwaye isebenze ngakumbi.
- Khusela izityalo: Eyona nto iphambili kukunciphisa umonakalo kwizityalo. Le teknoloji isetyenziselwa ukukhusela izityalo kwizinambuzane, izifo ezahlukeneyo zezityalo, kunye neemeko ezifana nembalela. Kwakhona, izityalo zenziwe ukuba zikwazi ukumelana neekhemikhali ezisetyenziselwa ukulawula ukhula, oko kukuthi, amayeza okubulala ukhula . Emva koko kususwa ukhula kuphela kwaye kushiyeke isityalo kuphela.
- Nciphisa amaxabiso okutya: Ngale ndlela, isivuno sinokwandiswa kwaye umonakalo kwizityalo ungancitshiswa, nto leyo enceda ekulawuleni amaxabiso okutya kwimarike ukuya kuthi ga kwinqanaba elithile.
- Ukunyusa ixabiso lesondlo: Ngamanye amaxesha obu buchwephesha bukwasetyenziselwa ukwandisa ixabiso lesondlo lokutya. Umzekelo, ukwenza kube sempilweni , ngaphandle kwamafutha e-trans.Kuye kwaveliswa iimbotyi zesoya eziqulethe iioyile ezisempilweni. Omnye umzekelo omhle yirayisi eguqulwe ngokwezakhi zofuzo ebizwa ngokuba yi "Golden Rice." Ityetyiswe ngesondlo esibizwa ngokuba yi-beta carotene (esiguqulwa ngumzimba wethu sibe yi-vitamin A). Oku kube luncedo olukhulu kubantwana kumazwe asakhasayo abasengozini yokungaboni ngenxa yokunqongophala kwe-vitamin A.
- Ukusetyenziswa kwixesha elizayo: Kwixesha elizayo, sinethemba lokusebenzisa obu buchwephesha ukususa izinto ezibangela i-allergens ekutyeni, ukutshintsha iiprofayili zezondlo, nokwenza inkqubo yokuvelisa isebenze kakuhle.
Zithini ukutya okuguqulwe ngokwemfuza?
Kukho izityalo ezininzi eziguqulwe ngokwemfuza ehlabathini. Ezinye zeemveliso esizisebenzisayo yonke imihla zenziwe ngezi. Ungafumana umbono ocacileyo ngazo kwitheyibhile engasezantsi.
| Uhlobo lokutya/lwesivuno | Isizathu sotshintsho/ingcaciso |
|---|---|
| Umbona | Ayinazo izinambuzane kunye nemithi yokubulala ukhula. Isetyenziselwa ukwenza izinto ezifana nesiraphu yombona kunye neoyile yombona. |
| Iimbotyi zesoya | Ukumelana nemithi yokubulala ukhula kunye nokuveliswa kweoyile enempilo. |
| I-Canola | Ukuze ikwazi ukumelana nemithi yokubulala ukhula. Ioyile yeCanola yenziwe ngezi zinto. |
| Umqhaphu | Ayinakonakala zizinambuzane. Isetyenziselwa amalaphu kunye neoyile yembewu yomqhaphu. |
| Amazambane | Ukunciphisa ukunsundu emva kokusikwa kunye nokumelana nezifo. |
| Ipapaya | Ukumelana nentsholongwane ebizwa ngokuba yiRingspot etshabalalisa imithi. |
| Islamoni | Uhlobo lwe- (AquAdvantage) lwenzelwe ukukhula ngokukhawuleza kune-salmon eqhelekileyo. |
| Ibhithi yeswekile | Ukumelana nezibulali-zinambuzane. Uninzi lweswekile kwimarike yethu luvela kwezi. |
Ukongeza, ezinye izityalo ezifana nama-apile, ii-eggplant, kunye namathanga nazo zitshintshiwe ngokwemfuza.
Ingaba kukhuselekile ngokwenene ukutya oku kutya kwe-GMO?
Kulungile, ngoku masingene kumbuzo obalulekileyo. Ngaba ukutya ezi zinto kulungile emzimbeni? Ingaba kubi? Kukho izimvo ezahlukeneyo ngale nto.
Zithini imibutho emikhulu efana neWorld Health Organisation (WHO)?
Uninzi lwee-arhente zempilo eziphambili kwihlabathi, kuquka i-World Health Organization kunye ne-U.S. Food and Drug Administration (FDA), zithi ukutya okuguqulwe ngokwemfuza okukhoyo kwimarike ngoku kukhuselekile njengokutya okuqhelekileyo . Zithi ixabiso lesondlo loku kutya liyafana nokutya okuqhelekileyo kwaye akukho bungqina bokuba ukutya oku kuzisa naziphi na iingozi zempilo ezongezelelweyo.
Eyona nto ibalulekileyo kukuba ukutya ukutya okune-GMO akutshintshi i-DNA yomntu (umntu okanye isilwanyana) okutyayo. Oko kukuthi, inkukhu etya umbona we-GMO ayibi yinkukhu ye-GMO.
Zithini iingxaki eziphakanyiswe ngabagxeki?
Kwelinye icala, abanye oososayensi kunye nabasebenzi bomzabalazo baphakamisa imibuzo malunga noku. Bathi:
- Ezi zinokubangela ii-allergies ezintsha.
- Iibhaktheriya ezinganyangekiyo kwii-antibiotics zinokuvela.
- Bakwathi akukho phando lwaneleyo okwangoku malunga nemiphumo yexesha elide yezi zinto. Ekubeni uninzi lwezifundo zangoku zilinganiselwe kwiinyanga ezimbalwa, bakholelwa ukuba akunakwenzeka ukutsho ngokuthe ngqo ukuba kuya kwenzeka ntoni ukuba uzitya iminyaka.
Ngoko ke, ungabona ukuba kukho amacala amabini koku. Kodwa imbono eyamkelekileyo ngoku kukuba ukutya kwe-GMO okukhoyo kwimarike okwangoku akubeki mngcipheko kwimpilo.
Singazi njani ukuba ukutya yi-GMO?
Oku kuyahluka ngokwamazwe ngamazwe. Kumazwe afana ne-United States, ukulebhelisha ukutya nge-GMO ngoku kuyimfuneko. Loo lebhelisha ingabandakanya izinto ezifana nezi:
- Uphawu olukhethekileyo lubekelwa ecaleni ngenxa yaloo njongo.
- Ikhowudi ye-QR eskeniwayo.
- Idilesi yewebhusayithi okanye inombolo yefowuni.
- Ukukhankanya amagama anje ngokuthi "Bioengineered" okanye "Genetically Modified Organism" kwiphakheji.
Ukuba ufuna ukuphepha ukutya okune-GMO ngokupheleleyo, enye yezona ndlela zilungileyo zokwenza oko kukuthenga iimveliso eziqinisekisiweyo ukuba "zendalo." Oku kungenxa yokuba ukuze uqinisekiswe ukuba yi-organic, imveliso kufuneka ingabi na-GMO. Ungakhetha neemveliso ezibhalwe ngokucacileyo ukuba "azina-GMO."
Ekugqibeleni, ukukhetha ukutya okune-GMO okanye ukungakukhethi sisigqibo somntu, kwaye kubalulekile ukuba wazi amacala omabini alo mba ngaphambi kokuba wenze eso sigqibo.
Umyalezo Wokuya Ekhaya
- I-GMO kukuguqulwa kwemfuza yesityalo okanye isilwanyana ukuze kunikwe uphawu oluluncedo (umz., ukumelana nezinambuzane).
- Ezi zenzelwe ukwandisa isivuno, ukukhusela izityalo, kwaye ngamanye amaxesha ukwandisa ixabiso lesondlo.
- Ngokutsho kwemibutho emikhulu efana neWorld Health Organisation, ukutya okune-GMO okukhoyo ngoku kukhuselekile ukutyiwa njengokutya okuqhelekileyo.
- Ukutya ukutya okune-GMO akuyi kuyitshintsha i-DNA yomzimba wakho.
- Abanye abantu bakhetha ukungatyi ukutya okune-GMO kuba abanye baphakamisa imibuzo malunga nemiphumo yako yexesha elide.
- Ukuba ufuna ukuphepha ii-GMO, khetha iimveliso ezibhalwe "Organic" okanye "GMO-Free."
- Ukuba unenkxalabo ethile ngempilo malunga nokutya kwakho okanye ukutya okuthile, kungcono ukuthetha nogqirha wakho ngayo.
