With the economic development and social progress, people’s work and life pressure are increasing day by day. The prevalence of thyroid diseases, especially hyperthyroidism, is increasing. Not only do hyperthyroid patients need timely formal treatment, but they should also pay attention to a diversified diet, develop a healthy lifestyle, maintain a good mood, enhance immunity, and actively prevent the disease from deteriorating. However, the dietary habits of many hyperthyroid patients are not scientific and reasonable. The general principle of diet for hyperthyroidism with high metabolic performance is to consume sufficient energy, ensure the quantity of staple food and increase the amount of high quality protein. 1. Hyperthyroidism patients should use more meat, eggs and milk, and food that is high in energy and rich in nutrients (see the table below). Avoid excessive one-time intake and increase the number of meals appropriately. In addition to the normal 3 meals, add 2-3 side meals. When clinical treatment is carried out, the supply of calories and other nutrients should be adjusted in a timely manner according to the condition. 2. Increase the supply of minerals and vitamins, especially potassium, calcium and phosphorus, etc. Use foods rich in vitamin B1, B2, B12, vitamin C, folic acid and niacin, etc. Eat more animal offal, liver and fresh green leafy vegetables, and supplement vitamin preparations when necessary. 3, hyperthyroidism patients are prone to goiter, so they should eat more food that can help dissipate the swelling, such as: rape, mustard, kiwi and so on. You should also eat foods that can improve your immune system, such as mushrooms, fungus, walnuts and red dates. 4, Chinese medicine believes that hyperthyroidism patients should eat less warm food, should nourish Yin, such as turtle, hold, duck meat, etc., to remember not to eat spicy, stimulating, excitatory food, common onions and ginger and pepper, coffee, etc., otherwise it may lead to aggravation or relapse of the disease, causing some harm to the health of patients. 5. The thyroid gland of hyperthyroid patients has an enhanced ability to synthesize thyroid hormones using iodine. Therefore, hyperthyroidism patients should avoid consuming higher amounts of iodine. Therefore, consume non-iodized salt, do not take nutritional supplements containing iodine, and health supplements and fortification, and do not eat foods containing more iodine. 6. Hyperthyroidism patients often have symptoms of increased bowel movements or diarrhea, so attention should be paid to limiting food fiber should be appropriately limited to foods containing more fiber. With the improvement of people’s health awareness, hyperthyroidism will also receive more and more attention. Strengthening the publicity and education of diet and other aspects will have positive significance in the prevention and control of hyperthyroidism.
