With thyroid nodules, it is usually possible to eat small yellowtail. However, if combined with hyperthyroidism, Hashimoto’s thyroiditis, it is not recommended to eat small yellowtail. Yellow croaker, also known as yellow croaker, is a seafood food with high iodine content. For people with thyroid nodules, if they have normal benign thyroid nodules and normal thyroid function, they can eat yellowtail if they maintain a normal healthy diet. If there is a combination of simple iodine deficiency and simple goiter, you can also eat foods with high iodine content such as yellowtail. It is recommended not to eat too much at one time, so as not to cause gastrointestinal discomfort. If there is a combination of hyperthyroidism or Hashimoto’s thyroiditis, iodine-rich foods such as yellowtail should be avoided, as this may not be conducive to disease control. Consult your physician or dietitian for specific dietary combinations.
