What is a low iodine diet? ”Iodine deficiency can cause many diseases, so is it better to eat more iodine? In fact, iodine intake can be harmful to the body, the most common being iodine-induced goiter and hyperthyroidism, which can also have a negative impact on intelligence. In particular, iodine intake should be strictly limited in the diet of patients with hyperthyroidism. So, why should hyperthyroidism patients not eat more iodine-containing foods? What kind of harm can be caused by eating them? Iodine is one of the important raw materials for the thyroid gland to synthesize thyroid hormones. The amount of thyroid hormones in the body of hyperthyroid patients is already higher than that of normal people, and if iodine-containing food is given, the hyperactive thyroid gland will synthesize more hormones, which will aggravate the condition. Moreover, the bioavailability of iodine in the thyroid gland of hyperthyroid patients is significantly higher than that of normal people. Even if they are given a small amount of iodine-containing food, the sick thyroid gland may produce more thyroid hormones than normal, thus aggravating the condition. We normal people will excrete excess iodine from the body after the organism has consumed too much iodine-containing food to avoid producing excess thyroid hormones. However, in hyperthyroidism, the thyroid gland is abnormally hyperfunctional and its own protection mechanism is dysfunctional. Instead of removing the excess raw material, the patient will overuse this iodine and synthesize a large amount of thyroid hormones, which will worsen the condition. This is why it is important to strictly control patients to adopt a low iodine diet at this time, so what is a low iodine diet? A low iodine diet is a food that contains little iodine. The highest iodine content in our daily life is seafood, such as our common kelp, nori, scallops, shrimp, dried ark, dried clam, dried scallop, light vegetable, sea cucumber, jellyfish, lobster, etc. are included. In addition to these foods, like iodized salt, soy sauce and other condiments iodine content is also very high. In addition, there are many other “iodine” products that are not easily found in our mouths, such as pickled vegetables, canned food and even cough medicines. For these foods, hyperthyroidism patients should not eat them.
