I think the USRDA for salt is around 2000mg. Salt is an electrolyte. Not enough salt/sodium in your system means your body doesn't function correctly...nerve impulses don't transmit right. Can cause severe leg cramping if you don't have enough salt in the body...which is typically only possible when you're sweating a lot, and drinking a lot of water to replace it, but not taking in any sodium.
Survivalist hikers will take a bag of salt with them, and take a pinch every couple hours to replace what they sweat out. This is also the reason Gatorade can be better for you than water sometimes...its full of electrolytes.
Too much salt is bad for the cardiovascular system. So, salt in moderation, and cuz out processed foods since they are loaded with sodium.
