Today sees the release of the Commons health select committee's report on obesity. Like all such reports almost no-one actually reads the thing itself, newspaper reports being easier to digest (if you excuse the pun). Anyway, the report apparently stops short of calling for regulation of TV advertising of junk food, instead arguing for voluntary controls. Nonetheless there are increasing calls for genuine, effective regulation. This has incited the usual moans about the "nanny state" from the free market fundamentalists, but this misses the point: we are talking about advertising deliberately targeting children and it is difficult to see what is wrong about nannying children. Surely that's exactly what they need?
