Thyroid nodules can eat broad beans, but need to be moderate.

Excessive or insufficient iodine intake can increase the prevalence of nodules, nodules with normal thyroid function should be suitable for iodine diet. If the thyroid nodule has autonomous function and leads to hyperthyroidism, an iodine-restricted diet is appropriate, i.e., consume non-iodized salt and avoid eating seafood.

The medication should be administered under the guidance of a doctor, and should not be used privately.
