If you have an underactive thyroid (hypothyroidism), incorporating iodine-rich foods into your diet can help support thyroid function. Here are some foods high in iodine:

1. Seaweed: Particularly varieties like kelp, nori, and wakame.
2. Fish: Cod, tuna, sea bass, and haddock are good options.
3. Dairy Products: Milk, yogurt, and cheese.
4. Shellfish: Shrimp, lobster, and other shellfish.
5. Iodized Salt: Salt fortified with iodine is an easy way to increase your intake.
6. Eggs: Particularly the yolks.
7. Cranberries: These can be consumed fresh, dried, or as juice.
8. Navy Beans: These legumes are a good plant-based source of iodine.
9. Potatoes: With the skin, as it contains more iodine.
10. Turkey: Another good source of iodine.

It’s essential to maintain a balanced approach, as both too little and too much iodine can negatively impact thyroid health. Consulting with a healthcare professional before making significant dietary changes is advisable, especially if you have an underlying thyroid condition.
