Dietary Recommendations for Hyperthyroidism Management

Iodine Restriction and Nutrient-Rich Foods

  • The American Heart Association recommends consuming a diet rich in fresh fruits and vegetables, whole grains, and high-fiber foods to support overall health, while limiting iodine intake from foods such as seafood, especially shellfish, and dairy products, which are moderate to high in iodine content 1, 2
  • A diet rich in fresh fruits and vegetables, especially those low in iodine, whole grains, and high-fiber foods, as well as lean proteins, is recommended to support thyroid function management, according to the American Heart Association 3
  • Avoiding extreme iodine restriction is necessary, as some iodine is still necessary for normal bodily functions, and moderation rather than elimination should be aimed for, as suggested by Clinical Nutrition guidelines 1, 2
