"The dairy industry is asking the Food and Drug Administration to allow it to add artificial sweeteners to some milk and dairy products. But it does not want to advertise ”reduced calories” in a prominent place on the label of the product."
Sources? I would be dismayed, and even shocked to find out if milk had added sugar in it without consistent labeling.
At least in the United States, milk must be sold with pasteurization, homogenization, and no additives. If it is different in the U.K, please enlighten us.
This is one of those things that varies across the UK thanks to devolution: Scotland bans raw milk products, but England and Wales don't IIRC. Even in England, you can only buy raw milk / cream directly from the producer. Raw milk cheese is available in ordinary shops though.
I can go into my local small supermarket and buy pasteurised, unhomogenised milk from Jersey cattle which is very, very rich. Fantastic for making custard!
The definition of what you're allowed to sell as 'milk' is probably set by the EU somewhere, but I've never seen milk have added ingredients listed, unless it's something like chocolate milk.
