The body said their inclusion reflected the growing popularity of non-dairy milk alternatives. Earlier this year farmers raised concerns about soya and almond "milk" being described as milk because it does not come from a cow.

The National Farmers Union said it had noticed several instances of milk alternatives being promoted in a way which does not make clear that they are non-dairy, therefore breaking EU rules.

EU rules state that certain names are reserved for dairy products, including "yoghurt", "milk", and "butter".

It comes after the Advertising Standards Agency banned an Arla advert which said organic dairy farming was "good for the land" for being "misleading".

This latest announcement by Arla appears to be the latest move to get more British consumers interested in milk again.

However its fizzy milk may prove more popular in the middle east, where fizzy dairy drinks are commonplace.

In countries including Iran, Turkey and Afghanistan a milky drink, which is often served fizzy, called Doogh is commonplace. It is made by mixing yoghurt and chilled or iced water and has been variously described as "diluted yogurt". It is sometimes carbonated and seasoned with mint.
