I've never been heavy handed with the salt. But, having to ration my daily salt intake (or pay for it later), has made me more aware of salt contents. As already said, processed foods are loaded with it.
I also salt my steaks, chicken and other meats up front... carefully. For things like stews, soups and chili, I wait until near the end of the cook to salt.It is my experience that too much salt too early in those cooks can leave you wishing you had been more careful when you get to the end of the cook. I also take into account the amount of salt in cured meats, like bacon or ham, if they are going into my cooking. When I make bean and ham soup, for example, I never add salt until the end of the cook -- and may not need to add any at all, depending on the saltiness of the ham.
I like potato chips, and have found the number of low salt and no salt chips on the store shelves are growing. Same with crackers. Having to ration my salt intake, I'm not going to waste my daily allowance on junk food. As I type, I am snaking on some "lightly salted" potato chips that have 66mg of sodium per 22 chip serving. After almost two years on this limited sodium diet regular full-salt chips taste way too salty to me.
BTW, what Kettle brand unsalted potato chips give up in salt, they make up for in depth of potato flavor. Whip up a little dip for them, and I don't miss the salt at all.
Everything is a tradeoff with my restrictions. Less salt in my snacks means I can go with a little more salt on my ribeye steak.
