Thyroid nodules are a common thyroid disorder, and many thyroid disorders can manifest as nodules. There are many causes of thyroid nodules, the more common being inflammation of the thyroid gland, autoimmune, genetic factors and neoplastic lesions. Thyroid nodules can be found in men and women of all ages, but are more common in middle-aged women. Thyroid nodules can be solitary or multiple, with multiple nodules having a higher incidence than solitary ones, while solitary nodules have a higher incidence of thyroid cancer compared to multiple nodules (the opinion of some doctors). Dietary precautions for thyroid nodules are as follows: 1. Iodine intake can be appropriately restricted and controlled: consuming large amounts of food high in iodine will increase damage to thyroid follicular cells and antibody production, which will aggravate the destruction of thyroid cells, so large amounts of seafood high in iodine should not be consumed. 2, should strictly avoid iodine: because iodine is one of the raw materials for the synthesis of thyroid hormones, too much iodine intake will increase the synthesis of thyroid hormones, thus aggravating the patient’s hyperthyroid symptoms, therefore, should not eat more iodine is also a contraindication to the diet of thyroid nodules. 3, non-functional nodules, diet can be less iodine based: it is recommended to eat less radish, cabbage and other foods, because these two foods will promote the growth of thyroid nodules, eat more is not beneficial to patients. 4, avoid smoking, alcohol: avoid spicy and stimulating food, such as onion, pepper and chili, cinnamon, etc..
