I've noticed that they've started to phase in the new star ratings on food. Don't know too much about it, just heard about it on the car radio a while ago. Food gets rated 1-5 stars depending on content and nutritional value. The rating appears on the packaging in a circle with the number of stars it's been graded at. Currently we've found it on cereals, yogurts and dessert pots (that's pudding pots in British!!). Not sure if it's being extended to all food stuff, but it would be extremely good if it was.
Hopefully it will at least, if only in a small way help people make better choices, especially if they don't understand food content, or are time poor, or have to drag their little darlings round the supermarket with them etc, making it difficult to examine food stuff properly.
