The human body contains about 50 quarts of water. But this body fluid is not pure water. It is actually a salt solution. Why is this so?
According to one scientific theory, all land animals, including man, are descendants of organisms that once lived in the sea and arose from it. The body fluid of these sea creatures was sea water, and when they left their life in the ocean and moved to dry land, they retained the sea water as their body fluid. Thus, the body fluid you now have is salty.
Since your body cells must have salt in order to live and work and since your body loses a certain amount of this salty fluid every day, that salt must be replaced through plant foods and meats which contain those needed amounts of salt.
Many people living in tropical climates actually take “salt pills” to help their bodies retain the great amounts of salt and water lost through excessive sweating.
In Ancient Rome, salt was so valuable and so scarce that Julius Caesar paid his soldiers in salt instead of money. Our word “salary” comes from the Latin word sal meaning salt!
