I put myself through college as a Sous Chef. I learned from a very good chef that salt is rarely needed in cooking. If you start with the items you don't realize that have salt you can slowly remove it from your diet. Salted butter can be replaced with non salted butter. Most items that you bake do not need it. Cookies, breads, bars etc. Secondly, you can always season to taste with salt. That means you can add salt at the table. My wife loves the shit. I don't use it. we purposely leave it out when we are seasoning and then each adds desired amount.
Some ways that I have found you can avoid adding salt. Spicier foods. for me more pepper needs less salt. When i marinate i use a dash of soy and Worcestershire sauce and skip salt for beef, and use an stronger herb for chicken, like lemon pepper or thyme. for me it's like sugar. The more you remove at once the more you miss it. but if you slowly tune it down you won't even notice it.
I ate corn on the cobb a couple days ago with no salt. My family thought it was crazy but it was actually good.
