Ngokwezibalo, ngaphezu kwe-75% yabantu baseRussia baphuza i-sweet soda ngezikhathi ezithile, futhi ukusetshenziswa kweziphuzo ze-carbonated kusondela amalitha angama-28 ngonyaka ngamunye. Uma ngezinye izikhathi ufinyelela i-cola neziphuzo ezifanayo, kusho ukuthi uzichaya ku-4-methylimidazole (4-MAYI) - i-carcinogen engaba khona eyakhiwe ngesikhathi sokukhiqizwa kwezinye izinhlobo zedayi ye-caramel. Futhi umbala we-caramel uyisithako esivamile eCoca-Cola nezinye iziphuzo ezithambile ezimnyama.
Abaphenyi bezempilo bomphakathi bahlaziye imiphumela kubantu yomkhiqizo ongaba yi-carcinogenic wezinhlobo ezithile zombala we-caramel. Imiphumela yocwaningo ishicilelwe ku- I-PLOS One.
Idatha yokuhlaziywa kokuhlushwa 4-MAYI ngeziphuzo ezibandayo eziwu-11 ezaqala ukushicilelwa ngo Consumer Imibiko ngo-2014. Ngokusekelwe kule datha, iqembu elisha lososayensi eliholwa iqembu elivela UJohns Hopkins Centre ngoba a Iyathandeka Ikusasa (I-CLF) kuhlolwe umthelela 4-MAYI kusuka kumbala we-caramel otholakala kuziphuzo ezibandayo futhi ulingise izingozi zomdlavuza ezingaba khona ezihambisana nokusetshenziswa okungaguquki kweziphuzo ezine-carbonated e-United States.
Kuvele ukuthi abathengi beziphuzo ezinjalo ezibandayo basengozini engadingekile yomdlavuza ngenxa yesithako esifakwa kulezi ziphuzo ngenxa nje yezizathu zobuhle. Futhi le ngozi ingavinjelwa kalula ngokugwema i-soda enjalo. Ngokusho kwabalobi besifundo, lokhu kuvezwa kubeka engcupheni impilo yomphakathi futhi kuphakamisa umbuzo wokuthi kungenzeka yini ukuthi kusetshenziswe umbala we-caramel kuziphuzo ezine-carbon.
Ngo-2013 nasekuqaleni kuka-2014 Consumer Imibiko ngokubambisana nayo I-CLF ihlaziye ukuhlushwa 4-MAYI Amasampula eziphuzo eziyi-110 athengwe ezitolo ezidayisa ezitolo eCalifornia naseNew York. Imiphumela ikhombisa ukuthi amazinga 4-MAYI zingahluka kakhulu kuye ngohlobo lwesiphuzo, noma phakathi kohlobo olufanayo lwesoda, ngokwesibonelo, phakathi kwamasampuli eDiet Coke.
Le mininingwane emisha iqinisa inkolelo yokuthi abantu abaphuza kakhulu iziphuzo ezine-carbonated bandise ngokungadingekile ingozi yokuba nomdlavuza.
