Cadbury Schweppes has been sued for 'misleading' consumers by labelling its Snapple drinks as 'all natural'.

The US$100m suit, filed in Manhattan federal court, alleged that the drinks contained high fructose corn syrup (HFCS), not 'all natural' ingredients as the bottle suggested.

The law suit explained: "HFCS does not exist in nature and is not 'minimally processed.' Describing HFCS as an 'all natural' ingredient is deceptive and unfair to consumers and competitors."

Cadbury Schweppes were not immediately available for comment.
