The diet of patients with Hashimoto (Hashimoto’s thyroiditis) should usually pay attention to eating less food with high iodine content, eating less and more frequent meals, eating high-fiber food appropriately, and paying attention to the reasonable combination of nutrients. 1. Eat less food with high iodine content: food with high iodine content, such as seaweed, nori and sea fish, should not be eaten more often. 2. Eat less and more meals: you should not overeat and drink to increase the burden on the gastrointestinal tract, so you should eat less and more meals. 3. Eat appropriate high-fiber foods: vegetables, coarse grains and other high-fiber foods help patients digest, but eating too much will lead to gastrointestinal peristalsis, which may cause diarrhea and other abdominal discomfort, so pay attention to moderate consumption. 4. Others: Pay attention to balanced nutrition, avoid spicy and stimulating foods, such as chili peppers, mutton, strong tea, coffee, etc.; pay attention to sleep and rest, maintain good mental health, and exercise appropriately. Consult your physician or dietitian for specific dietary combinations, and seek prompt medical attention if you have any uncomfortable symptoms.
