Zakudya za Transgenic, zomwe zimadziwikanso kuti zakudya zosinthidwa mwanjira inayake, ndizo zomwe zimakhala ndi tizidutswa ta DNA kuchokera kuzinthu zina zamoyo zosakanikirana ndi DNA yawo. Mwachitsanzo, zomera zina zimakhala ndi DNA yochokera ku mabakiteriya kapena bowa zomwe zimatulutsa mankhwala achilengedwe, zomwe zimapangitsa kuti zizitetezedwa ku tizirombo ta mbeu.
Kusintha kwa zakudya zina kumachitika ndi cholinga chowongolera kukana kwawo, mtundu ndi kuchuluka komwe kumapangidwa, komabe, kumatha kubweretsa zoopsa zathanzi, monga kuwonjezera kupezeka kwa chifuwa komanso kumwa mankhwala ophera tizilombo mwachitsanzo. Pachifukwa ichi, choyenera ndikusankha momwe zingathere pazakudya zachilengedwe.
Chifukwa chiyani amapangidwa
Zakudya zomwe zimasinthidwa chibadwa zimachitika motere, ndi cholinga cha:
- Sinthani mtundu wazomaliza, kuti mukhale ndi michere yambiri, mwachitsanzo;
- Wonjezerani kukana kwanu tizirombo;
- Kusintha kukana mankhwala ophera tizilombo omwe agwiritsidwa ntchito;
- Lonjezerani nthawi yopanga komanso yosungira.
Kuti apange chakudya chamtundu uwu, opanga amafunika kugula mbewu kumakampani omwe amagwira ntchito ndi zomangamanga kuti apange ma transgenics, omwe amatha kukweza mtengo wazogulitsazo.
Kodi zakudya za GM ndi ziti?
Zakudya zazikuluzikulu zomwe zimagulitsidwa ku Brazil ndi soya, chimanga ndi thonje, zomwe zimabweretsa zinthu monga mafuta ophikira, zotulutsa za soya, mapuloteni a soya, mkaka wa soya, soseji, margarine, pasitala, ma crackers ndi chimanga. Chakudya chilichonse chomwe chili ndi zosakaniza monga wowuma chimanga, manyuchi a chimanga ndi soya wophatikizika, atha kukhala ndi transgenics momwe amapangira.
Malinga ndi malamulo aku Brazil, cholembera cha zakudya chomwe chili ndi 1% yazinthu zosinthika chiyenera kukhala ndi chizindikiritso cha transgenic, choyimiridwa ndi kansalu kachikaso kokhala ndi chilembo T chakuda pakati.
Zitsanzo za zakudya zosasinthasintha kuti zithandizire
Mpunga ndi chitsanzo cha chakudya chomwe chasinthidwa ndi chibadwa kuti chichiritse, monga kulimbana ndi HIV kapena kuwonjezera pa vitamini A.
Pankhani ya mpunga wolimbana ndi kachilombo ka HIV, mbewu zimatulutsa mapuloteni atatu, antioclonal 2G12 ndi lectins griffithsin ndi cyanovirin-N, omwe amalumikizana ndi kachilomboka ndikuchepetsa mphamvu yake yopatsira maselo amthupi. Njerezi zimatha kulimidwa pamtengo wotsika kwambiri, zomwe zimapangitsa kuti matendawa azitsika mtengo kwambiri. Kuphatikiza apo, njerezi zimatha kugayidwa ndikugwiritsa ntchito mafuta ndi mafuta oti azigwiritsidwa ntchito pakhungu, kulimbana ndi kachilombo kamene kamapezeka munkhungu za ziwalo zoberekera.
Mtundu wina wa mpunga wosanjikiza wothandizira ndi womwe umatchedwa Golden Rice, womwe udasinthidwa kuti ukhale wolemera mu beta-carotene, mtundu wa vitamini A. Mpunga uwu udapangidwa makamaka kuti athane ndi kuchepa kwa mavitamini awa m'malo amphaŵi , monga zigawo za Asia.
Mavuto azaumoyo
Kugwiritsa ntchito zakudya zosinthika kumatha kubweretsa zovuta zotsatirazi:
- Kuchuluka kwa chifuwa, chifukwa cha mapuloteni atsopano omwe amatha kupangidwa ndi ma transgenics;
- Kuchuluka kwa kukana kwa maantibayotiki, komwe kumathandizira kuchepetsa mphamvu ya mankhwalawa pochiza matenda a bakiteriya;
- Kuchulukitsa kwa zinthu zapoizoni, zomwe zimatha kuvulaza anthu, tizilombo ndi zomera;
- Kuchuluka kwa mankhwala ophera tizilombo m'zinthu, monga ma transgenics amalimbana kwambiri ndi mankhwala ophera tizilombo, kulola opanga kuti agwiritse ntchito zochulukirapo kuteteza munda ku tizirombo ndi namsongole.
Pofuna kupewa zoopsa izi, njira yabwino kwambiri ndi kudya chakudya chamagulu, chomwe chimalimbikitsanso kuwonjezeka kwa mankhwalawa ndikuthandizira opanga ang'onoang'ono omwe sagwiritsa ntchito mankhwala ophera tizilombo m'minda yawo.
Zowopsa Pazachilengedwe
Kupanga zakudya zopitilira muyeso kumawonjezera kukana kwawo, komwe kumalola kugwiritsa ntchito kwambiri mankhwala ophera tizilombo ndi mankhwala ophera tizilombo m'minda, zomwe zimawonjezera chiopsezo chodetsa nthaka ndi madzi ndi mankhwalawa, omwe amathera pakudya kwakukulu ndi anthu komanso adzasiya nthaka ili yosauka.
Kuphatikiza apo, kugwiritsa ntchito mankhwala ophera tizilombo mopitirira muyeso kumatha kuyambitsa zitsamba ndi tizirombo tomwe timagonjetsedwa ndi zinthuzi, zomwe zimapangitsa kuti zikhale zovuta kulamulira nthaka.
Pomaliza, alimi ang'onoang'ono nawonso ali pachiwopsezo chifukwa, ngati agula mbewu kuchokera kuzakudya za GM, azilipira ndalama kumakampani akulu omwe amapanga mbewu izi, ndipo nthawi zonse azikhala okakamizidwa kugula mbewu zatsopano chaka chilichonse, malinga ndi mgwirizano womwe udakhazikitsidwa .
