i've done alot of research on this type of thing...........i'm one of those people who crave salt & salty foods........all my life........it took me a very long time to find out that craving sodium is the adrenals way of trying to get what it needs to make many of the adrenal hormones.........without it, the adrenals suffer.......adrenal hormones also have alot to do with intestinal integrity.........excess sodium can cause the walls of the intestines to b non-porous........this causes the liquid from the chime that is made from the foods u eat, to b too thin..........it also causes the nutrients in that chime to go right thru..........potassium has to b in balance with sodium, for each person, according to their needs........if someone is eating low sodium & foods high in potassium, this can cause D.........but if there isn't enough potassium in ones body, then the intestinal walls r not porous enough..........causing the chime to pass thru too fast & very little in the way of nutrients & water getting into the body, thru those walls..........some potassium for those who do eat salty stuff, would help to balance the sodium & enable the intestinal walls to b more porous, letting alot of the liquid thur, into the system..........potassium has a lot to do with muscle contraction........if the intestines r to spastic, causing D, then potassium will slow & relax those intestines, which r nothing but muscles..........the thing is, to find out just how much potassium u need.........if u r consuming high potassium, then some sodium, in the way of sea salt, would help then, because too much of it can really cause D in a big way.........sodium gets a bad rap.........it's all about the balance..........
