Seafood is one of the best natural sources of iodine. Fish like cod, tuna, and haddock, as well as shellfish such as shrimp and seaweed (kelp and nori), are particularly high in iodine.
Dairy foods like milk, yogurt, and cheese can be good sources of iodine, primarily because iodine is used to clean equipment in dairy processing, leading to its presence in dairy products.
One of the most common sources of iodine in the diet is iodized salt. This type of salt is fortified with iodine to prevent iodine deficiency, which can lead to thyroid problems.
Eggs contain a moderate amount of iodine, and they can be a part of a balanced diet to contribute to your iodine intake.
Seaweed, such as kelp, nori, and dulse, is incredibly rich in iodine, and it's often used in Asian cuisines. However, it's essential to consume seaweed in moderation due to its high iodine content.
Some fruits and vegetables grown in iodine-rich soils can also be good sources. Examples include potatoes, strawberries, and cranberries. The iodine content of these foods can vary depending on soil conditions.
Beans, especially navy beans, are a source of iodine, albeit in smaller amounts compared to seafood and dairy products.
Meat, such as beef and chicken, contains iodine, although the content is generally lower than in seafood and dairy products.
