The choice of iodized or non-iodized salt should be made on a case-by-case basis. The general public generally needs to consume iodized salt, but hyperthyroid patients need to consume non-iodized salt. Because iodine is a necessary raw material for thyroid cells to synthesize thyroid hormones, lack of iodine in the body will lead to a series of diseases called iodine deficiency disorders. Patients with iodine deficiency disorders have no obvious clinical symptoms in the early stages, and have mild to moderate diffuse goiter, which is soft and has no pressure pain. So the general public needs to consume iodized table salt to avoid iodine deficiency. Hyperthyroidism is caused by the body’s increased synthesis and secretion of thyroid hormones due to various causes. Iodized salt can contribute to thyroid hormone secretion, so hyperthyroid patients should choose non-iodized salt. Iodine is deficient in some areas of China, and adding iodized salt to daily consumption salt can reduce iodine deficiency. Different iodine supplementation strategies are chosen according to different regions to meet the body’s iodine needs. If you are not sure about your condition, it is recommended that you go to the hospital to have your thyroid hormones checked and choose your consumption salt under the guidance of your doctor.
