Mawu akuti "zamasinthika kusintha" kapena "ma genetically" angamveke owopsya, koma pali zokhoza zedi zopulumutsira miyoyo ndi kuwongolera thanzi pochita kusintha kwa zomera zomwe zimapereka zakudya zomwe timadya tsiku lililonse.
Zakudya zamagetsi (zomwe zimatchedwanso kuti zamoyo zopangidwa ndi mavitamini kapena GMO) si zoipa pa thanzi lanu. Ndikumvetsa kuti anthu ambiri ali ndi vuto la chitetezo cha GMO, koma kwenikweni, akhala akukhala kwa nthawi yaitali, ndipo amafufuzidwa kwambiri.
Malinga ndi United States Food and Drug Administration (FDA), pafupifupi 81 peresenti ya soya ndi 40 peresenti ya chimanga zopangidwa ku United States zimasinthidwa. Mwinamwake mwakhala mukudya zakudya za GMO kwa nthawi yaitali.
Nthaŵi Zambiri Zomwe Zimabzalidwa Nthawi Zonse Koma Mofulumira
Anthu akhala akuchita izi kwa zakudya zawo mwachibadwa kwa zaka zambiri. Njira yachikale yokhala ndi mavitamini omwe amasinthira mbewu ndi zomera zosiyana siyana zomwe zimasonyeza makhalidwe omwe mlimi akufuna kusintha. Pakati pa nyengo zingapo, mikhalidwe yosankhika idzaonekera kwambiri. Tsoka ilo, mtundu uwu wa kusinthidwa ndi pang'onopang'ono komanso moperewera.
Mitundu yowonongeka yokhala ndi zakudya zokhala ndi zokolola zimapitanso njira zochepa zowonjezera kachitidwe kokalekeza. Zomera zimatha kusinthidwa kuti zikhale zosagonjetsedwa ndi tizirombo kapena kusinthidwa kotero kuti mbewu zotsutsa zimagonjetsedwa ndi opha-udzu. Izi zikutanthauza kuti opha njuchi amphamvu azigwiritsidwa ntchito ku zomera.
Mankhwalawa samangopangika kuti zomera zikhale zosavuta kukula. Zomera zingasinthidwe kuti zikhale ndi zakudya zabwino kapena zowonjezera chitetezo chawo.
Mwachitsanzo, zomera zina zomwe zimakhala ndi calcium yambiri zingasinthidwe kuti zichepetse chiwerengero cha oxalates.
Oxalates nthawi zambiri amamanga kashiamu ena ndipo amawapangitsa kuti asamapezeke m'thupi. Kusinthidwa uku kuchepetsa oxalate kungalole kuti calcium yambiri imveke.
Chinthu chinanso chotheka ndicho kusintha mapeyala kuti mapuloteni awo asakhale ochepa; kusintha kumeneku kungapulumutse miyoyo ya anthu omwe akudwala matendawa. Inde, zingakhale zovuta (ndi zoopsya) kuyesa izi panthawi ya chitukuko.
GMOs Sizowopsya Basi
Lingaliro la zakudya zamakono limapangitsa anthu ena kukhala ndi mantha. Kufufuzira msanga pa intaneti kudzabweretsa malo ochokera m'magulu osiyanasiyana omwe akudera nkhaŵa za chitetezo chokula ndi kudya zakudya zomwe zasinthidwa.
Madera ena akudandaula ndi awa:
- Zomwe zingathe kupanga chiwopsezo mosazindikira
- Mwinanso kufalitsa mankhwala ophera tizilombo
- N'zotheka kuipitsa nyama
- Lingaliro lakuti zakudya izi sizochibadwa
- Kodi zakudya zopangidwa ndi majini ziyenera kulembedwa?
Mitengo yokhala ndi zomera yowonjezera imayesedwa kuti ikhale yotetezeka mbewu isanafike kwa alimi. Dipatimenti ya Ulimi ya United States (USDA), FDA ndi Environmental Protection Agency (EPA) ikugwiritsidwa ntchito poletsa zomera za zomera, kuphatikizapo zomwe zimakhudza thanzi labwino, chilengedwe komanso chitetezo cha zakudya.
