Did you ever stop to think about how much salt is used in our foods? Almost any foods you buy from the store including, canned, mixes, sauces and most everything except fresh foods are already salted for us. If you store foods for emergency such as dried, dehydrated or even frozen foods, you will need some kind of salt for all of them. So will everyone else. You can also use salt for other things like preserving meats and fish. It will also be in demand if ever the stores would be closed for any length of time. Natural news tells us why we should be storing Himalayan salt.
