Cod
Cod is a white fish that has a mild flavor and soft texture. It has low fat and calorie quantities, but provides a wide range of nutrients and minerals, such as iodine. According to the Icelandic Food Content Database, fish that contain low fat levels have the highest iodine level.
For example, 85 grams of cod has approximately 63-99 mcg, or 42-66% of the recommended daily amount. The level of iodine in cod depends on if the fish was raised in a farm or caught in the wild. It also depends on the region where the fish was caught. Lean fish usually contain about 66% of daily iodine value.
