I agree with Elly that you should try to use fresh and organic foods. However, if you must eat canned foods, draining the liquid will remove a lot of the salt. How much, I don't know. Better less salt than all the salt. I doubt you would lose a whole lot of nutrients. Being salt restricted, I would try to avoid processed foods. Even so called "reduced sodium" foods can be high in sodium. They're just reduced from their normal extremely high amounts of sodium. I would suggest making your own beans. Dry bean are are really easy. You just can't have them on the spur of the moment since they need at least couple of hours soak time. Don't use any included seasoning packet. Use a little bit of sea salt, and lots of your own seasonings. Good luck!
