Which foods contain iodine?

Seaweed is one of the best sources of iodine. Fish, seafood, dairy, eggs and iodized salt are also good sources.^[1]

Iodine per serving in some foods:

• cod, 3 ounces: 146 µg^[1]
• nori seaweed, 2 tablespoons (5 g): 116 µg^[1]
• oysters, 3 ounces: 93 µg^[1]
• plain Greek yogurt, 3/4 cup: 87 µg^[1]
• nonfat milk, 1 cup: 84 µg^[1]
• iodized salt, 1/4 teaspoon: 78 µg^[1]
• egg, 1 large: 31 µg^[1]
• cheddar cheese, 1 ounce: 14 µg^[1]

Most fruits and vegetables contain little iodine, and the amount depends on the soil.^[1] Sea salt, kosher salt and Himalayan salt are usually not iodized. In the US, most processed foods are made with salt that has no iodine.^[1]
