Sounds like everything is right on target! If your mom is craving chips, then she must be my soul mate! LOL! I LOVE salty things, and I eat them. I probably could take less blood pressure medication, if I reduced my salt intake. But for me, it is a quality of life issue - I take my BP medication and eat my salt!
Of course, if someone told me I would die if I kept eating salt, I would quit - but so far, so good!
