Whether to take iodized salt or non-iodized salt with thyroid nodules generally needs to be judged according to the functional status of the thyroid gland, and patients are advised to seek timely medical treatment. If patients with thyroid nodules are accompanied by hypothyroidism, they can take iodized salt, which can maintain the normal level of thyroid hormones to a certain extent. If the patient is accompanied by hyperthyroidism, he can eat non-iodized salt, so as to avoid the iodine content is too high to affect the level of thyroid hormones, if the thyroid function is normal, iodized salt and non-iodized salt can be consumed in moderation. Patients with thyroid nodules should pay attention to a balanced diet in their daily life and go to the hospital for regular checkups to understand the development of the disease.
