Some salty facts
• The amazing Salar de Uyuni (the world’s largest salt flat at 4,000 square miles) in Bolivia becomes mirror-like when a thin layer of water lies on top. This reflectivity makes it a very useful tool in calibration scientific equipment from outer space. This amazing salt flat also contains half of the world’s supply of lithium.
• Salt is so essential to the body that if you drink too much water it can flush it out of your system and cause fatal hyponatremia.
• Consumption of too much salt can be deadly — you need to take about one gram of salt per kilogram of weight to die and this was used as a method of ritual suicide in China — especially amongst the nobility as salt was so expensive.
• Good quality sea salt contains many essential minerals for the body. The best type of sea salt should be slightly wet from the sea it was taken from.
