Dietary Considerations for Hypothyroidism Management

Iodine Intake and Medication Interactions

  • Excessive iodine intake should be avoided as it can worsen hypothyroidism in iodine-sufficient individuals 1
  • Iodine-containing medications should be used with caution in hypothyroid patients 1
  • Ensure adequate but not excessive iodine intake, with adults needing approximately 150 μg/day, and an upper limit of 300 μg/day 1, 2

General Dietary Recommendations

  • Limit processed foods high in sodium, as hypothyroid patients may have increased cardiovascular risk 3
  • Focus on whole foods including fruits, vegetables, whole grains, lean proteins, and healthy fats 4, 5
  • Include iodine-rich foods in moderation, such as fish, dairy products, and iodized salt 2, 6
  • Consider milk and dairy products as they are important sources of iodine in many diets 6
  • Be aware that organic milk and plant-based milk alternatives typically contain less iodine than conventional milk 6
