Adding salt to you food is bad. All the salt your body needs can be obtained from a balanced diet. The desire for salt on your food is a learned taste. You can train yourself to reduce your desire for it and eliminate it altogether. I read a story about that when I was in secondary school . . . I tried it and proved it to be true. I have not wanted to add salt to my food ever since.
A couple days ago at a restaurant I saw a very fat woman at a table next to me receive food from a waiter. Before he even put the plate down in front of her she was reaching for the salt shaker. I watched her shake out 20-30 shakes onto the plate and this was before she even tasted one bite! Seeing that made me want to vomit. Clearly, it was a habit of hers and she probably does the same thing at home. Is that the direction you want to head in? Again, you can train yourself to go without salt very easily.
We have a combined salt and pepper shaker in the kitchen. The pepper part is used periodically while cooking, but the salt portion has never been used. I recoil when I go to a party and find heavily salted snack treats like chips. Lightly salted cashews or peanuts is all I can stand and even that has to be in small doses.
