A low-iodine diet is prescribed before diagnosticradioactive iodineuptake (RAIU) tests and before radioactive iodine treatments.

The RAIU test is an imaging scan used to check thyroid health.

The low-iodine diet is a special diet that limits the amount ofiodineyou can consume through foods and beverages.

It does not naturally occur in the body, so it needs to come from these foods or supplements.

Thethyroid glanduses dietary iodine to produce thyroid hormones that regulate metabolism.

Too little or too much iodine can cause or worsen thyroid disease.

A low-iodine diet is necessary when preparing for a radioactive iodine uptake (RAIU) test or treatment.

This diet is required to “starve” the thyroid of iodine and reduce the amount of resident iodine.

Lowering amounts of resident iodine makes the thyroid “iodine hungry.”

RAI uptake into the thyroid cells allows them to be visualized on a diagnostic imaging scan.

It can also destroy tumor cells when this therapy is used for thyroid cancer treatment.

But it requires some planning.

Instead, you could use non-iodized and kosher salt because they do not contain iodine.
