Patients with calcified thyroid nodules need to be cautious about their diet. Firstly, they should avoid irritating foods such as chili peppers, ginger, garlic, strong tea, coffee, and alcohol. Secondly, they should not consume foods high in fiber as these can cause diarrhea. Instead, they should eat foods rich in carbohydrates and fats, which provide energy and reduce the consumption of proteins in the body, as proteins play an important role in physiological regulation. Additionally, these patients should consume foods rich in vitamins and minerals to aid physiological metabolism. Lastly, it is beneficial for patients with calcified thyroid nodules to include animal organs in their diet.
