Lumka ke lumka .. ikofu ibangela umhlaza

Izityholo ezintsha zingavalela ikofu ngonaphakade emva kweendonga zemvume, kwaye isigwebo asikakhutshelwa, inkundla yase-US yaseCalifornia ingenza isigqibo kwisimangalo esinxulumene nekofu, kwaye ukuba isigwebo siyavumelana nalo mthetho, iikhefi kunye neevenkile zekofu ziya kufuneka zibeke isilumkiso malunga nekofu kunye nokuba nokwenzeka kokubangela umhlaza wesifo. Basenokude bahlawule isohlwayo ukuba ababalumkisi abathengi ngeengozi zemichiza ekwikofu.

Emva kweli tyala lifakiweyo, iBhunga leMfundo yeToxic kunye noPhando, lijonge ukohlwaya iinkampani ezingahoywayo ngokulumkisa abathengi ukuba ikofu iqulethe into.

I-Acrylamide yikhompawundi yeekhemikhali eyenza ngokwendalo kwiintlobo ngeentlobo zokutya xa kuphekiwe, kuquka ikofu.

Umbuso waseCalifornia ubeka i-acrylamide kwizintlu zayo ze-carcinogens, esi sizathu sokumangalelwa kweBhodi yeMfundo ngokumelene neenkampani.

Yintoni i-acrylamide?
Le nto idla ngokubunjwa ngokwemvelo xa iinkozo kunye nezityalo ziphekwe kumaqondo aphezulu, kwinkqubo esebenzayo ebizwa ngokuba yi "Maillard reaction", apho ukushisa okuphezulu kusebenza khona ukuguqula incasa kunye nombala weswekile kunye ne-amino acids, ukuze umbala wabo ube mdaka. , kwaye oku kwenzeka ngokufudumeza iitapile isonka, iibhiskithi okanye ikofu, kunye nezinye iintlobo ze-acrylamide. Kodwa akukho sizathu siqinisekileyo, ukuza kuthi ga ngoku, sokukholelwa ukuba ikofu okanye okunye ukutya kubeka abantu kumanqanaba ayingozi e-acrylamide, kwaye akukho ndlela eyaziwayo yokwenza ikofu ngaphandle kokudlula kwi-acrylamide.
iacrylamide kunye nomngcipheko womhlaza
Ikhemikhali ekuthethwa ngayo yafunyanwa kuqala ngoososayensi baseSweden ngo-2002, ngokutsho kwe-American Cancer Society.
Idatha ibonisa ukuba ubukho be-acrylamide ngobuninzi ekutyeni bubangela umhlaza kwezinye izilwanyana, kwaye uphando lubonise ukuba ukubeka i-acrylamide emanzini okusela kunokubangela umhlaza kwiimpuku.

Kodwa iidosi ezisetyenzisiweyo kwezi zifundo ziyi-1000 ukuya kwi-100 amaxesha aphezulu kunoko abantu abaqhele ukukufumana ekutyeni kwabo.
Amagosa akwiGunya loKhuseleko loKutya laseYurophu athi: “Kusenokwenzeka ukuba le nto ibikhona ekutyeni ukusukela oko kwaqalwa ukuphekwa, kuba ukuqhotsa, ukubhaka kunye nokuqhotswa konke kudala i-acrylamide. (Le yimeko yokutya okuvela kwizityalo, kuquka iinkozo, kodwa kungeyomfuneko ngenyama okanye intlanzi).” Kodwa i-acrylamide ayibeki mingcipheko ebantwini kwiingozi zemizi-mveliso, xa iphefumlelwa ngabantu ngobuninzi.
Le nto ikwayenye yeekhemikhali ezininzi eziveliswa kumsi wecuba, nangona zininzi kakhulu kunekofu eshushu okanye ithowusti.
Kubalulekile ukukhumbula ukuba ngumlinganiselo wethamo lomchiza ogqiba ukuba ingaba yingozi na.Ikhafeyine, efumaneka kwikofu, inokubulala kwiidosi eziphezulu - kodwa oko akuthethi ukuba ikofu iyingozi ngokupheleleyo.

Kwaye ukuba utya ukutya okuphekiweyo, i-acrylamide ayinakuphetshwa, njengoko ikhona malunga nesithathu sekhalori ezityiwa ngumntu oqhelekileyo waseMelika okanye waseYurophu.
Ngokwesiqhelo, i-metabolism yaloo khemikhali ebantwini yenzeka ngendlela eyahlukileyo kunezilwanyana, kwaye ukuza kuthi ga ngoku, izifundo azikafumani ngokucacileyo naluphi na unxibelelwano phakathi kokusetyenziswa kokutya okuqulethe i-acrylamide kunye neentlobo ezahlukeneyo zomhlaza eziqhelekileyo.
Kuyo nayiphi na imeko, uninzi lwedatha ukuza kuthi ga ngoku lubonisa ukuba abantu abadla ikofu eninzi banomngcipheko ophantsi wezifo ezininzi zesibindi, izifo zentliziyo, uhlobo lwesifo seswekile se-XNUMX, ukudakumba, kwaye kubaluleke kakhulu kulo mzekelo kunye nomhlaza, onokuthi ube nomhlaza. ingozi.
