I presume that the idea of the empowering impact of food content traffic lights comes from the same stable as the proposal to put warning messages on chocolate wrappers ("more than anything else this will liberate children from the threat of obesity"). We seem to be increasingly surrounded by such behaviour these days. You cannot watch a decent film without dire warnings that "the following film contains infrequent mild references to sexuality" or sit down in front of the six-o-clock news without a seriously-faced announcer saying "the following report may contain scenes that might upset some people". I even now find warnings when I try to download music from Napster (the other day I discovered a "Parental Advisory" warning label on a Tommy Dorsey record from the 1940s - as it was a non-vocal track I assume the warning related the the fact that the tune might be catchy!)
What would really represent a brave step forward in the general direction of civilisation would be if we could ban all such nonsense, and - while we were at it - limit the use of the word "empower" to consenting adults in the privacy of their own homes after the watershed.
