According to a study conducted by the Consumer Reports on the effect of caramel colouring used in soft drinks, the daily consumption of fizzy drinks is more dangerous than we thought.
The laboratory tests on 11 different soft drinks revealed that one can a day could be enough to expose a consumer to potentially cancer-causing levels of the chemical 4-MeI, which is short for 4-methylimidazole. Surprisingly however, the levels of 4-MeI varied in samples of the same type of fizzy drinks. Tyler Smith, the lead author of the Johns Hopkins study, the team that led the Consumer Reports researchers, said that “For example, in diet drinks, certain samples had higher or more variable levels of the compound, while other samples had very low concentrations”.
