Yes Randy I agree, human body can't do without sodium, I think the limit can't exceed more then 2300ml that equals to a table spoon for a healthy diet. The minimum sodium a human required daily is 500mg, I take that in a meal, the rest of the meals I try to avoid it.I used to work in a medical clinic for about 7 years at night when I went to college to help pay the bills. They had posters on the wall about high blood pressure and sodium so I got the not so bright idea to virtually eliminate it from my diet. Trust me, DON'T EVER DO THAT!!!! One night I went to work as usual and the next thing I knew I got probably the worst cramp in my leg that I've ever had before or since, the pain was severe and I promptly passed out. Fortunately that place had an E.R. They took blood test and found one thing and one thing only. My blood sodium levels were below the normal for MINIMUM. Long story short, stay within the dietary guidelines for sodium intake especially if you sweat a lot on the job.
I understand you can get too much sodium, but you can't live w/o it either so I'm just trying to give a warning to be moderate, but don't eliminate it. I do have high blood pressure and the doctors can't tell me why and honestly they don't know why. If they do they're keeping that info to themselves. All most doctors know how to do is prescribe this pill for that problem and charge a bundle for doing it. I eat moderately and limit sodium to well within dietary guidelines.
