I'm somewhat confused why salt is usually avoided on a paleo diet.

From what I have read it's done because too much salt isn't good for you
which is not in dispute by anyone. Also because there's no 'known' evidence
it was used by people earlier than 8500 years ago (in Austria, a landlocked
country).

Except I was thinking, wild animals do seek out salt licks. Salt occurs
naturally in deposits and can be found all over in rock form (usually where
ancient seas used to be). Salt can also be found in salt flats where it
just builds up, I think one well known place for this is in Florida.

So ancient people would have observed the behavior of the animals, and
tried it out themselves. Maybe they did the same thing. Why not? And people
who lived on coastlines that caught fish and stuff would also have been
aware of the taste of salt.

I did some reading about salt, and it seems as if there is a big difference
between UNREFINED sea salt which is full of minerals and trace elements,
and refined salt which is considered a poison. Apparently unrefined sea
salt is very good for the body according to one web page I looked at. It's
also very hard to get.

It is not in debate that the body absolutely does need some salt to
function optimally. We will die if our salt intake becomes 0. The question
is how much is appropriate.

From what I am reading, the discussion about salt in North America is
talking about 'grams' of salt per day. Except, where am I going to get all
that salt from? it sure isn't part of any food I buy/make (since for now
I'm doing it strict). I don't really have any salt cravings, but when I eat
something that tastes utterly bland without salt I'm like 'what a boring
lifeless meal I wish it had just a bit more flavour'.

Thoughts?

Best,
P.
