Maererano nenhamba, vanopfuura 75% veRussia vanonwa soda inotapira nguva nenguva, uye kushandiswa kwekabhoni kunwa kunosvika 28 litres per capita pagore. Kana iwe dzimwe nguva ukasvika kune imwe cola uye zvinwiwa zvakafanana, zvinoreva kuti uri kuzviratidza kune 4-methylimidazole (4‑CHIVABVU) - inogona kuita carcinogen yakaumbwa panguva yekugadzirwa kweimwe mhando dzekarameli dhayi. Uye ruvara rwe caramel chinhu chinowanzoitika muCoca-Cola uye nezvimwe zvinwiwa zvine rima.
Vatsvagiri vehutano hweveruzhinji vakaongorora mhedzisiro pavanhu yechinhu chinogona kuita carcinogenic yemamwe marudzi ecaramel. Mhedzisiro yekutsvaga yakaburitswa mu PLOS One.
Yekufungisisa yekuongorora data 4‑CHIVABVU mune 11 zvinwiwa zvakasiyana zvakatanga kuburitswa mu Consumer Reports muna 2014. Kubva pane iyi data, boka idzva remasayendisiti rinotungamirwa nechikwata kubva Johns Hopkins pakati nokuti a Inogoneka Future (CFL) vakaongorora kukanganisa 4‑CHIVABVU kubva kune iyo caramel color inowanikwa mune zvinotonhorera uye yakateedzera ingangoita kenza njodzi dzinosanganisirwa nekungogara uchinwa macarbonated zvinwiwa muUnited States.
Zvakazoitika kuti vatengi vezvinwiwa zvakadaro vane njodzi isingaite yekenza nekuda kwechinhu chinowedzerwa pazvinwiwa izvi nekuda kwezvikonzero zvekushamisa. Uye iyi njodzi inogona kudzivirirwa nekungodzivirira yakadaro soda. Sekureva kwevanyori vechidzidzo ichi, kuratidzwa uku kune ngozi kune hutano hweveruzhinji uye kunomutsa mubvunzo wekugona kwekushandisa kara ye caramel muzvinwiwa zvine kabhoni.
Muna 2013 uye kutanga kwa2014 Consumer Reports muchibvumirana na CFL akaongorora kusangana 4‑CHIVABVU 110 sampuro dzechinwiwa chinotengwa kubva kuzvitoro zvekutengesa muCalifornia neNew York. Mhedzisiro yacho inoratidza kuti iwo mazinga 4‑CHIVABVU inogona kusiyanisa zvakanyanya zvichienderana nerudzi rwechinwiwa, kunyangwe pakati pemhando imwechete yesoda, semuenzaniso, pakati pemasampuli eDhi Coke.
Iyi dhata nyowani inosimbisa iko kutenda kwekuti vanhu vanodya yakawanda yakawanda yekabhabhoni zvinwiwa zvisina basa vanowedzera njodzi yekuva nekenza.
