I am on a sodium kick lately.   One thing that I have found to be incredibility hard is to get under the recommended daily allowance of  2400mg.  Take my V8 juice as an example.  I purchased a can of V8 juice from the vending machine. One would think its the healthiest option in there but upon close review of the back, I discover that this one can has nearly 700mg of sodium.  That is almost 1/3 of my total intake for the day!  Just goes to show how much the food industry has relied on sodium for the purpose of preservation.
