A six-year European study suggests that, while salt did cause "a slight uptick in systolic blood pressure" over time, their findings didn't really support a "society-wide cutback in salt intake." In fact, people on low-salt diets were more likely to die from a stroke or heart attack.

Eat salt at a moderate level and don't worry about it. i.e. don't actively bother trying to avoid salt, but don't go eating a whole bag of salt & vinegar chips.
