A low iodine diet, as the name suggests, means eating foods with less iodine content. Iodine is one of the important raw materials for the synthesis of thyroid hormones, and when patients with hyperthyroidism eat too much iodine, it will promote the secretion of thyroid hormones in the body, which will aggravate the condition. Therefore, these patients should strictly control the intake of iodine in their daily life. Common low iodine foods include chicken, duck, turtle, shrimp and eggs. In addition, oranges, bananas, papayas, mangoes and other foods are also low in iodine. However, it should be noted that kelp, sea vegetables and sea fish are high iodine foods. For patients with hyperthyroidism, it is also necessary to consult a doctor in a timely manner and carry out standardized treatment under the guidance of the doctor.
