Yes, it's daft to say the least. Here in Italy they spout it as a healthy breakfast food, together with bread and fruit juice. What they really mean to say is the bread and fruit juice are healthy. Apparently it's healthy because of all the nuts, but they omit to mention the vast amounts of fat and sugar.
Mind you, I have no faith in Italian advertising standards, Kinder is frequently pushed as being nourishing because it contains milk. Shame about all the other crap that's in it.
sorry about the rant, a bugbear of mine.
Can you not complain to advertising standards in the UK? Surely they're quite strict and this is misleading info imo.
