Cov lus ntawm "genetically modified" lossis "genetically engineered" yuav ua rau lub suab ntshai, tab sis yeej muaj lub peev xwm zoo rau kev cawm neeg lub neej thiab kho kom zoo los ntawm kev hloov cov kev hloov rau cov nroj tsuag uas muab cov zaub mov peb noj txhua hnub.
Cov khoom noj uas muaj kabmob (tseem hu ua cov kabmob lossis hloov kabmob (GMOs) kuj tsis zoo rau koj kev nojqab haushuv. Kuv nkag siab ntau ntawm cov neeg yog leery of GMO kev ruaj ntseg, tab sis, qhov tseeb, lawv tau nyob ib ncig ntawm ntev, thiab lawv raug tshawb fawb ntau.
Raws li United States Food and Drug Administration (FDA), yam tsawg kawg 81 feem pua ntawm cov taum pauv thiab 40 feem pua ntawm cov pob kws ua tau tsim hauv Tebchaws Asmeskas yog hloov kev hloov. Koj twb tau noj cov zaub mov GMO ntev.
Ib tug Lawm zoo li Kev Nyab Xeeb Nyhav Tab Sis
Tib neeg tau ua qhov no rau lawv cov khoom noj tau ntau xyoo. Txoj kev qub qub los hloov cov khoom noj qoob loo yog kev sib txuas ntawm cov nroj tsuag uas pom cov yam ntxwv ntawm tus neeg ua liaj ua teb xav kom txhim kho. Dhau ob peb lub caij, qhov zoo tshaj plaws qhov yuav ua rau pom tseeb. Hmoov tsis, hom kev hloov kho no yog qeeb thiab qis me ntsis.
Txheej txheem engineering cov qoob loo ntawm cov qoob loo mus ob peb kauj ruam dhau qhov qub txheej txheem ntawm kev ua qoob loo. Cov nroj tsuag tuaj yeem hloov txoj kev hloov kom lawv muaj kab mob ntau dua rau cov kab tsuag los yog kho kom zoo li ib txoj hau kev uas cov qoob loo cog rau cov nroj tsuag. Qhov no txhais tau hais tias muaj zog maj mam tua cov nroj tsuag mus rau cov nroj tsuag.
Genetically engineering tsis tas rau kev cog ntoo yooj yim tuaj. Nroj tsuag tau muab kho kom zoo dua qub rau lawv cov khoom noj khoom haus lossis txhawb lawv txoj kev nyab xeeb.
Piv txwv, qee cov nroj tsuag uas feem ntau muaj cov txiaj ntsim zoo ntawm cov calcium uas yuav ua rau kev hloov kho kom txo tau cov xov tooj ntawm cov oxalates uas lawv tsim tawm.
Oxalates feem ntau khi qee cov calcium thiab ua rau tsis txaus rau hauv lub cev. Qhov kev hloov no kom txo qhov oxalate yuav tso ntau calcium uas yuav tsum tau nqus tau.
Lwm txoj kev yuav hloov tau cov txiv laum huab xeeb kom lawv cov nqaijrog yog cov tsis haum; qhov kev hloov no yuav txuag tau lub neej ntawm cov neeg uas raug kev txom nyem los ntawm qhov kev tsis haum tshuaj no. Ntawm chav kawm, nws yuav nyuaj (thiab txaus ntshai) kuaj qhov no thaum txoj kev loj hlob.
GMOs Tsuas yog Tsis Ntshai
Lub tswv yim ntawm cov khoom noj khoom haus ua muaj zog ua rau qee tus neeg tshee. Kev tshawb nrhiav hauv Internet yuav coj cov chaw los ntawm ntau pawg neeg uas txhawj xeeb txog txoj kev nyab xeeb loj hlob thiab noj cov khoom noj uas raug hloov kho.
Qee qhov ntawm kev txhawj xeeb yog:
- Tej zaum yuav tsis pom kev ua xua
- Tej zaum yuav kis tau cov kab siv tshuaj tua kab rau cov nroj tsuag qus
- Ua tau rau toxicity rau cov tsiaj
- Lub tswv yim hais tias cov khoom noj yog tsis zoo li qub
- Puas yog cov khoom noj khoom haus hauv geneticically tau sau tseg?
Cov noob caj noob ces yog tshawb nrhiav kev nyab xeeb ua ntej cov noob raug muab rau cov neeg ua liaj ua teb. Lub Teb Chaws Asmeskas Lub Tsev Haujlwm Saib Xyuas Kev Ua Qoob Loo (USDA), FDA thiab Environmental Protection Agency (EPA) yog txhua tus koom tes hauv kev tswj cov nroj tsuag genetically, nrog rau nws cov kev hloov rau cov nroj tsuag kev noj qab haus huv, ib puag ncig, thiab zaub mov kev ruaj ntseg.
