I agree that varying the diet is important but canned soups are just so not worth there salt...pun intended
However If its soup you crave may I make a suggestion of a way to have it but do it more healthy?
Chicken Noodle Soup
-2 Can of low/no sodium chicken broth
-2 chicken breasts cooked (just 25-30 mins in the oven is all you need)
-3 full carrots cut into circle slices
-1 cup of green peas
-parsley,white pepper,rosemary to flavor
-Whole grain noddles of choice (cook and set aside when soup is almost done)
Just heat up the broth with the carrots, when they get close to desire texture add the chicken,spices and peas and let simmer for little longer. Add the noodles and there you go.
Still some sodium but not as much and whole grain noodles and good chicken meat. Also because its better and lower in badness you can have a little more
