Don't have a specific advise, but generally I don't consume nor trust news articles about given country, from given country. So I read about my central European homeland from neighboring news, or BBC/Guardian for example.

Its more difficult with US since every fart affects rest of the world, sometimes massively, but some sort of averaging in my mind does it for me. Or at least I think it does, what is truly objective is a goal worthy of maybe academic discussions, I don't think individual can easily even get to it and realize 'this is it'.
