Due to high metabolism, the demand for nutrients in hyperthyroidism patients has increased significantly. If nutritional supplements are insufficient, weight loss will be more obvious, so diet is very important for patients with hyperthyroidism, and special attention should be paid to the reasonable collocation of nutrients. Diet should be based on the principle of high calorie, high protein, high vitamins, moderate fat and sodium salt intake. The daily calorie intake of men should be at least 2400 kcal and that of women should be at least 2000 kcal. Eat foods rich in calories, protein and vitamins, especially foods rich in potassium and calcium. Young patients also need to eat more foods with high fat content and fruits and vegetables rich in vitamins. Vitamins and inorganic salts can regulate physiological functions and improve metabolism, especially vitamin B and vitamin C. Sufficient calcium and iron should be supplemented to prevent deficiency. Because hyperthyroidism is caused by excessive secretion of thyroid hormones, it has a lot to do with iodine, so it is necessary to control iodine intake and fast foods with high iodine content such as kelp, laver, seaweed, kelp, marine fish, shrimp and jellyfish skin. When necessary, the iodized salt can be changed to non-iodized salt. Be careful or not to use warm supplements and dietotherapy products with high iodine content. Eat less and eat more, don't overeat. Eat less or no spicy food (such as pepper, onion, ginger, garlic, etc.). ), try not to smoke, drink, drink less or not to drink strong tea, coffee and other stimulating drinks, so as not to aggravate symptoms such as palpitation and shaking hands. Proper control of high-fiber food, hyperthyroidism patients often have diarrhea, such as excessive supply of fiber-rich food will aggravate diarrhea.
