Perhaps, but I came across an interesting comment in
_Much depends on dinner : the extraordinary history and
mythology, allure and obsessions, perils and taboos, of an
by Margaret Visser (McClelland and Stewart, Toronto, 1986)
Visser comments that the human craving for salt seems to
be correlated to the rise of agriculture and hence a
diet consisting largely of vegetable matter. Meat eating
peoples don't seem so concerned with salt. Also she
observes that carnivores aren't frequenters of salt licks
except to predate upon salt-licking herbivores.
Thus the need for salt may depend strongly on the diet.
I don't have the book with me, but I can probably find
a reference in the bibliography tonight if you are interested.
