There are no known means of preventing the onset of hyperthyroidism.
For those individuals diagnosed with Graves' disease, it is important that medication be taken as directed and for as long as necessary to achieve the greatest chance of permanent remission from disease. Patient compliance in this is essential.
Although lack of iodine in the diet is associated with hypothyroidism, growth retardation and intellectual disability, it has been shown that in areas of low iodine intake there is an increased incidence of nodular toxic goiter, especially in elderly women. Only a few places in the world ensure adequate dietary iodine intake through natural foods (seaweed, kelp and other seafood) and most of the world's population relies on iodized salt for its source. In areas where there is no national supplementation program, it is important to ensure that supplemental iodine is taken, especially during pregnancy and in young children, to maintain a healthy thyroid.

Although no other dietary precautions are necessary in hyperthyroidism, a well-balanced diet, adequate rest and moderate exercise will help maintain general good health and guard against symptoms of the disease being provoked or exacerbated.
