The high TSH hormone indicates a state of subclinical hypothyroidism. The main foods that these patients should not eat are those that are particularly high in iodine, such as kelp and nori, because studies have confirmed that excessive iodine intake in hypothyroid patients can aggravate the damage to the follicular cells of the thyroid gland, leading to a worsening of the hypothyroid situation. Other than that, there is no special contraindication for other foods, including iodized salt, which can be consumed to supplement iodine, but not in excess. However, drugs with high iodine content, such as amiodarone, should not be taken for a long period of time, as they can also cause excessive iodine intake. The iodine content of seafood is relatively low, so patients with hypothyroidism or high TSH can eat it appropriately, there is no special contraindication.
