Is seafood high in iodine?

Seafood is a common food with high iodine content. For normal people, eating seafood in moderation can supplement nutrients for the body, and the body has a certain metabolic function, which usually does not cause the accumulation of iodine in the body. However, if you eat seafood in excess, it may lead to excessive iodine content, so you need to control your intake.

Iodine is necessary for the synthesis of thyroid hormones, which help regulate the body's metabolism and also promote the development of the nervous system. If the body is deficient in iodine, it may cause an enlarged goiter. However, for patients with hyperthyroidism, it is necessary to eat less or no food with high iodine content such as seafood as much as possible, otherwise it may stimulate the increase of thyroid hormone secretion, cause thyroid tissue to harden, and further worsen the condition of hyperthyroidism.

Common seafood with high iodine content in daily life mainly include scallops, sea cucumbers, lobsters, jellyfish, hairtail, etc. Patients with hyperthyroidism should avoid eating them. If it is an iodine-deficient population, the intake of the above foods can be appropriately increased, and the situation of iodine deficiency can be improved by supplementing iodine-containing edible salt.
