I don't add any salt to anything except for a teaspoonful when I make bread, and I certainly don't put it on food either - freshly ground black pepper is a far nicer substitute. I have naturally high sodium levels and was told to avoid salt wherever possible, so I tend to avoid processed foods. If my sodium levels do drop, then I have a treat of a packet of mini-cheddars or a rasher of bacon with my breakfast. I also avoid sugar wherever possible. When I make porridge or rice pudding, I don't add any sugar at all and I have found a very nice "no added sugar" muesli which gets all its sweetness from the dried apples in it. I do like cake but even then I cut down the amount of sugar in them and once the cake has cooled I cut it into slices and put it in the freezer so one cake can last me a few weeks, a particularly useful back up if my sugar levels drop.
