Yes, but perhaps not very well-informed.

Some health nuts get their health information from unreliable sources like newspapers and magazines.

[Skrej]

It's very common (at least in AmE) to tag 'nut' onto another noun to show that a person is very interested or enthusiastic about something, almost to the point of obsession. It can be used both as both a pejorative and as self-deprecation.

I suppose you could use any combination you want, but some of the more commonly heard ones are:

health nut
gun nut
car nut
baseball/soccer/sport nut

[Tdol]

In the US, do people use gun nut in anything other than a pejorative sense? I only hear it used negatively on this side of the pond, where things are very different on this issue.

I am afraid they do. That favourable usage even occurs here in Canada, where legal controls on guns are similar to those in Europe, and not like the US at all.

And Facebook. Misinformation flows around in circles, masquerading as real information that's backed up by science. If you actually follow the impressive-looking links, you will eventually get back to where you started.
