The recommended daily limit for salt is 6 grams as far as I know. It's quite difficult to stay within that limit if you eat what is seen as a healthy diet. Breakfast cereals can have a surprisingly high salt content. Two slices of bread instantly take a gram of salt out of your allowance. Like soup? Most cans contain 2-3 grams of salt. Packaged meals can be packed full of salt, especially curry.
The only way to be healthy is a balanced and varied diet in my opinion. Keep your saturated fat levels down (> 20g a day), eat fruit and veg regularly, and at least keep an eye on your salt. And of course, combine it with some regular exercise.
