1. Control iodine intake: Because most patients have thyroid nodules, it is caused by too little iodine intake. Therefore, patients can eat some foods with high iodine content in daily life, such as kelp, scallop, jellyfish, lobster, turtle and other seafood, but residents in coastal areas must pay attention to eating less seafood and controlling iodine intake to avoid diseases.

2, do not eat irritating food: patients should pay attention to avoid eating some spicy, irritating, greasy food, such as pepper, garlic and so on.

Patients should eat more light diet and some supplements as little as possible, otherwise it will increase the burden of thyroid and affect treatment.

3, taboo spicy food: pepper, raw onion, raw garlic. Avoid high-fat and fried foods. There is no strong tea, coffee, cigarettes and wine. Taboo seafood: kelp, shrimp and hairtail. Stay calm and avoid fatigue.
