Patients with thyroid nodules will gradually reduce the secretion of thyroid hormones and slowly make the thyroid lose its regulatory function, so we must pay attention to the following two aspects in diet. First, patients with thyroid nodules should eat more foods with the function of eliminating nodules and reducing swelling, such as rapeseed, mustard greens and kiwifruit. You should also eat more foods that can enhance immunity, such as mushrooms, fungus, walnuts, coix seed, red dates, yams, fresh fruits and so on. Second, patients with thyroid nodules should be forbidden to eat spicy food, such as pepper, pepper, sesame pepper and so on. Eating high-fat fried foods, smoking and drinking should also be banned. Pay more attention to rest in daily life, don't stay up late, ensure adequate sleep, and develop good work and rest habits.
