What diet drinks don’t have aspartame in them?

A common sweetener, aspartame is to be labelled a possible carcinogen next month

A common sweetener used in a number of popular diet drinks is set to be declared a possible carcinogen by the World Health Organisation (WHO) next month.

The International Agency for Research on Cancer (IARC), an arm of the WHO, is poised to introduce the label from July, sparking concerns amongst consumers as to the content of the food and drinks they consume.

The IARC ruling was finalised earlier in June, and is intended to assess whether something is a potential hazard.

The ingredient set to be re-labelled is aspartame, a popular artificial sweetener found in an array of food products including Diet Coke, chewing gum and light yoghurt.

Discovered in 1965 by US chemist James Schlatter, it is approximately 200 times sweeter than regular table sugar.

A low-calorie sugar substitute, it was approved by the U.S. Food and Drug Administration (FDA) in 1974 to be used as a tabletop sweetener and additive in breakfast cereals, among other foods. It was first approved for UK use in 1982.
