Yup, I certainly get that some extra salt will aid in fending off dehydration. Probably why the daily bacon and jerky set me just about right. I too operate daily on low sodium. There is no salt shaker on the dinner table and I rarely season anything I am cooking unless someone else is going to eat it. As a kid growing up I can remember the salt shaker was passed around the table every meal! I can immediately tell when I have had too much such as when having dinner at a friends or a cookout. The MH meals left me feeling like I had a brick in my guts, that's why I am looking to find a happy medium.
