Most people vastly underestimate the amount of salt they will need in the survival scenario. This happens because all of our food is pre-salted right now by food manufacturers. So we don't think we need extra salt. But in the absence of processed, pre-salted food, an individual's need for real salt is surprisingly high.Salt is essential for life. That's why every land animal seeks out salt and craves it. It's why ocean creatures live in waters made out of salt. It's why human blood is fundamentally made with salt. Your body cannot retain water without salt, and when hospital drips and IV solutions into your bloodstream keep you alive, it's a salt solution! So keep several bottles of Himalayan Salt on the shelves of your kitchen.
