Kodi kununkhiza kwa ndudu zamagetsi kumawerengedwa ngati utsi wa fodya?

Kafukufuku wa nitrosamines mosakayikira ndiye gawo lofunikira kwambiri pamaphunziro ambiri.Malinga ndi mndandanda wa World Health Organisation wa carcinogens, nitrosamines ndiye carcinogenic primary carcinogen.Utsi wa ndudu uli ndi ma nitrosamines (TSNA) ambiri okhudzana ndi fodya, monga NNK, NNN, NAB, NAT… Pakati pawo, NNK ndi NNN zadziwika ndi WHO ngati zinthu zoyambitsa khansa ya m'mapapo, zomwe ndizomwe zimayambitsa khansa. za ndudu ndi zoopsa za utsi wa fodya."Wolakwa".

Kodi utsi wa e-fodya uli ndi ma nitrosamines enieni a fodya?Pofuna kuthana ndi vutoli, mu 2014, Dr. Goniewicz anasankha zinthu 12 zogulitsa kwambiri za e-fodya pamsika panthawiyo kuti azindikire utsi.Zotsatira zoyeserera zikuwonetsa kuti utsi wa ndudu zamagetsi (ziyenera kukhala za m'badwo wachitatu wa utsi wotsegula wa ndudu) unali ndi nitrosamines.

Ndikoyenera kudziwa kuti zomwe zili mu nitrosamines mu utsi wa e-fodya ndizochepa kwambiri kuposa utsi wa ndudu.Deta ikuwonetsa kuti zomwe NNN zili mu utsi wa e-fodya ndi 1/380 yokha ya NNN zomwe zili mu utsi wa ndudu, ndipo zomwe NNK zili ndi 1/40 chabe ya NNK zomwe zili mu utsi wa ndudu."Kafukufukuyu akutiuza kuti ngati osuta asintha ndudu za e-fodya, akhoza kuchepetsa kusuta kwa zinthu zovulaza zokhudzana ndi ndudu."Dr. Goniewicz analemba m’pepalalo.

Mu Julayi 2020, US Centers for Disease Control and Prevention idapereka chikalata chonena kuti mulingo wa nitrosamine metabolite NNAL mumkodzo wa ogwiritsa ntchito ndudu ndi yotsika kwambiri, yomwe ndi yofanana ndi kuchuluka kwa NNAL mumkodzo wa osasuta. .Izi sizimangotsimikizira zotsatira zochepetsera zovulaza za ndudu za e-fodya pamaziko a kafukufuku wa Dr. Goniewicz, komanso zimasonyeza kuti zinthu zamakono zamakono za e-fodya zilibe vuto la utsi wa fodya wochokera ku ndudu.

Kafukufukuyu adatenga zaka 7 ndipo adayamba kusonkhanitsa deta yokhudzana ndi matenda okhudzana ndi kusuta fodya mu 2013, kuphatikizapo machitidwe, machitidwe, zizoloŵezi, ndi zotsatira za thanzi.NNAL ndi metabolite yopangidwa ndi thupi la munthu pokonza ma nitrosamines.Anthu amakoka ma nitrosamines pogwiritsa ntchito fodya kapena utsi wa fodya, kenako amachotsa metabolite NNAL kudzera mkodzo.

Zotsatira za kafukufukuyu zikuwonetsa kuti kuchuluka kwa NNAL mumkodzo wa osuta ndi 285.4 ng/g creatinine, ndipo pafupifupi kuchuluka kwa NNAL mumkodzo wa osuta e-fodya ndi 6.3 ng/g creatinine, ndiko kuti, zomwe zili. wa NNAL mu mkodzo wa osuta e-fodya ndi wa osuta 2.2% ya chiwonkhetso.
