Iodine is a necessary mineral found in some foods. Foods that contain iodine include: fish (such as cod and tuna), seaweed, shrimp, other seafood, dairy products, and iodized salt. Getting enough iodine is important for everyone, especially infants and women who are pregnant.

Processed foods, such as canned soups, almost never contain iodized salt. In addition, specialty salts, such as sea salt, kosher salt, Himalayan salt, and fleur de sel, are not usually iodized.
