I salt to taste, preferably during cooking rather than at the table, but there are certain things I'd always salt at the table (e.g. poached eggs). I tend not to eat pre-processed foods, so am confident I'm controlling my salt intake adequately. It's an excess that's bad for you, not "any at all".
I'm noticing more and more people obsessing about salt. Don't get me wrong, it's good that the issue has been raised and is in people's minds, but I do despair at the constant fight and self-denial people manage to get themselves into when it comes to food. It just seems rather sad when the first question is always "how much x does it have in it?" rather than "how does it taste?"
