Consumers are being exposed to an "avoidable and unnecessary cancer risk" from an ingredient being added to soft drinks, according to a new study.

Researchers, led by a team at the Johns Hopkins Center for a Livable Future (CLF) analysed the risk of 4-methylimidazole (4-MEI) - a possible human carcinogen formed during the manufacture of some types of colouring.

While they were unable to recommend one brand over another, or draw conclusions about specific brands, the results did show that levels of 4-MEI can vary greatly.

This unnecessary exposure poses a threat to public health and raises questions about the continued use of caramel colouring in soda.
