There are no four so-called dietary contraindications for Hashimoto’s thyroiditis. It should be noted that Hashimoto’s thyroiditis should pay attention to reducing the intake of iodine-containing foods when symptoms of hyperthyroidism occur, as well as appropriately restricting foods high in dietary fiber in order to reduce the occurrence of diarrhea. When symptoms of hypothyroidism occur, reduce the consumption of fatty foods to avoid indigestion and other discomforts. Hashimoto’s disease, also known as Hashimoto’s thyroiditis, is an autoimmune disease, and dietary management can help patients recover from the disease after regular medication. Patients with Hashimoto’s thyroiditis usually need to know if thyroid function is affected, and if hypothyroidism is present, then treatment requires thyroxine supplementation as prescribed by the doctor. Patients with Hashimoto’s thyroiditis should reduce their intake of iodine-containing foods and iodized salt when they develop hyperthyroidism, consume high-energy, high-protein, high-vitamin diets, and limit foods that are high in dietary fiber. For more information about food, consult a nutritionist for scientific and rational consumption under the guidance of a physician.
