Got Salt?

With the advent of refrigeration, our salt consumption gradually reduced through the years.  Since salt up to the time of refrigeration the main way that we preserved food was with the use of salt.  In fact, it is interesting to note that prisoners of war, even on their meager and undernourished diets had on average 20 to 28 grams of salt per day.  Not prisoners of war, today Americans consume on average far less than the 20 to 28 grams.
