$this->bbcode_second_pass_quote('pstarr', '')$this->bbcode_second_pass_quote('sameu', 'w')hy is salt so important?
Ever see a deer or a cow at a salt lick? We need it to live.

Humans and other animals need salt for normal metabolic function. It's useful as an antiseptic and for food storage, but just for life in general
we need salt. I was talking to someone recently who has veganish tendencies
and
was sure people don't need any salt in their diets. That person is wrong.
$this->bbcode_second_pass_quote('', '[')b]ECOLOGY
Natural salt licks have been available for as long as we know and have always provided a valuable source of minerals and trace elements to wildlife, especially herbivores.
Since the majority of plants do not provide sufficient amounts of sodium and may lack adequate chloride, salt licks are a necessary part of most free-range herbivore diets. In addition to sodium and potassium salts, vital minerals such as calcium, phosphorus, copper, cobalt, zinc, iodine, iron, manganese and selenium are found in salt licks. In essence the salt lick is a big Flintstones vitamin spread out over the forest floor, and you know that you have to take your vitamins to grow up big and strong! Large numbers of fossils have been found at salt mine sites around the US, as these huge salt licks were a natural meeting place for herbivores and fertile hunting ground for carnivores.

The distribution of local sources of sodium essentially determines the spatial and temporal structure of moose
populations. Salt licks play an important role in the ecology of moose as a factor promoting their regular distribution under conditions of the mountain-taiga landscape and also affecting breeding activity; i.e., increasing the probability of encounters of mating partners.

MEDICINEHuman HyponatremiaAn elecrolyte disorder which occurs when the sodium level in the blood drops below 110mEq/L (Normal is 135-145mEq/L).
Causes
* Excessive water intake.
* Inadequate sodium intake.
* Loss of sodium rich body fluids.
* SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion)
-------------------------------------------------------------------------------------------------
BIOLOGY AND NUTRITIONSodium and CL intakes can very tremendously within human populations. The range of habitual daily intakes of salt compatible with a normal life span is from less then 2 g (Yanamamo Intians of the Amazon Basin) to 35 g (Northern Island of Japan)...
Under most circumstances, approximately 0.5 g of NaCl daily would represent an adequate intake. However, the peoples of most world regions consume 10-35 times this amount...
(Dietary deficiency is uncommon)
However,
infants fed formulations with low NACL developed severe metabolic alkalosis because of CL deficiency. Sodium deficiency would only rarely be
expected and only
in populations that consume no salt and rely entirely on plant food grown in inland areas low in soil NA. Early signs and symptoms of a Na deficiency would be a progressive fall in urinary NA, and a dramatic reduction in work capacity and psychologic function...

NATIVE CULTURESNATIVE AMERICAN TRAILS
In some instances, buffalo trails, such as the ones
leading in
to the great
salt lick near the future Nashville, were up to four feet wide and worn as much as two feet below ground level...
...Shells were especially prized on the interior, while deerskins were desired on the coasts, and these were traded regularly. Salt was another
item of exchange, as noted by the earliest explorers.

HISTORY As a precious and portable commodity, salt has long been a cornerstone of economies throughout history. In fact, researcher M.R. Bloch conjectured that
civilization began along the edges of the desert because of the natural surface deposits of salt found there.
