Why is that a candy bar has lower sodium than a meal that's supposed to be good for you?

I was appalled to discover a breakfast bowl had 1590mg of sodium. It was so salty I could barely eat it. Then I looked at the soup I planned to have today and yegads! 850mg in one serving! My miniature Hershey bar has 25mg spread out between 5 mini bars (5mg each). Anyone have a good low sodium split pea soup recipe?
