Of course, if government is declared as responsible for nutrition, then then naturally it must also be responsible for the effects thereof.
This is a significant reason why state control must always beget more state control: regulators must make an at least ostensible attempt to correct unintended effects that are the result of a given intervention. The domain of responsibility becomes effectively unbounded.
While devising a complex system by means of patches in ad infinitum can work (see, Linux kernel), but only if that system's usage is constrained by voluntary choice.
Sadly, this means that folks with a given expertise (say, medical), will say things like they do in TFA: the sort-sighted view that governments should generally increase or at least maintain spending in order to avoid the expected bad effects of backing out on a responsibility.
There can be no substitute for individual responsibility.
