Is Nutella healthy?

As part of my New Year Health Kick, I have started going to the gym and trying to eat more healthily. Well, I also have a fondness for Nutella and had a vague recollection that it might be "healthy". I checked my impeccable academic source, Google.com, and came up with this article:

Well, who knew? It turns out Nutella is not especially nutritious :-( Which is a bit galling, as I've just bought a 400g jar. But if this is the case, why is Nutella deliberately trying to engage its target consumers (children) with an attractive, interactive website?

Anyway, the point is about misleading claims in advertising and to what extent we, as consumers, should be naive and believe everything marketers tell us. Personally, I adopt a very robust sceptiscim about anything I read that tries to promote a product or service (or, indeed, a political party). Also, as marketers, it does renew the call for responsible and ethical marketing practice.
