4. Himalayan salt
If you are trying to avoid eating conventional table salt, but you want to increase your iodine intake, Himalayan crystal salt is another option. Unlike conventional table salt, which has to be fortified with iodine, Himalayan crystal salt contains iodine naturally. In fact, just half a gram contains about 250 mcg of iodine, which is more than 150 percent of the daily recommended intake. While it is so dense in iodine, you do want to use it sparingly, however; too much iodine can have adverse effects that are similar to not getting enough.
