Hashimoto’s hypothyroidism refers to Hashimoto’s thyroiditis combined with hypothyroidism. It is recommended to avoid long term consumption of foods with goitrogenic effects in large quantities, e.g., cabbage, kale, cassava. If hypothyroidism is caused by iodine overdose, iodine intake needs to be restricted. Hashimoto’s thyroiditis is an autoimmune inflammatory disease of the thyroid gland that may be associated with hypothyroidism. There are no foods that can’t be eaten in hypothyroidism, but there are some foods that need to be limited in intake and the way they are consumed. For example, cruciferous vegetables such as white radish can be eaten cooked and avoided with dipping sauces; and high-fat, high-cholesterol foods such as cream and animal offal should not be eaten as much as possible. It is recommended that patients with Hashimoto’s thyroiditis combined with hypothyroidism go to the hospital in time and follow the doctor’s instructions for treatment to avoid delaying their condition.
