Yes, there are lots of different kinds of salt: pink, iodized, kosher, sea, etc. They come from salt mines in the ground, or from evaporating the water out of salt water. What they all have in common is that infamous mineral that I’m going to talk about below: sodium.
In food, salt is used for both flavor, and as a preservative. Salt helps to preserve food by drawing out the water that bacteria and mold need to grow. Hence, preserving the food from spoiling as quickly.
Would you be surprised to know that 75% of our salt intake comes not from the salt shaker? It comes from processed foods. Snacks like chips, pretzels and salted nuts are included here. But so are canned foods, pickled foods, boxed foods, deli meats, restaurant food, and fast food.
