Key Lecture Points
- Salt is one of the few minerals that are both abundant and useful. It is made up of sodium and chloride and is found all over the world. It is produced by mining and by solar evaporation. Salt is necessary for both human and animal life. It has thousands of uses but is most commonly used as a winter road deicer and as a food preservative and seasoning.
- Salt has been prized since ancient times for its ability to preserve food. It was also commonly used as an antiseptic. Through history salt has been a religious and ceremonial metaphor because of its ability to preserve, prevent decay and keep its essence—salt can be dissolved into a liquid and then evaporated back to crystals.
- Salt has played key roles in world history from the rise of Venice as the major trading city between Europe and Constantinople to the bitterly hated French salt tax that was a major grievance against the monarchy before the French Revolution to being a military strategy to defeat the South in the American Civil War and the spark that set off the Indian civil disobedience movement and the Indian fight for independence.
- For decades federal health authorities have advised Americans to cut their sodium intake. Although no one disputes that too much salt can raise blood pressure, new evidence raises the question: how much is too much?
