Dietary Modifications for Managing Hypothyroidism

Key Dietary Recommendations

Ensure adequate iodine intake of 150 μg per day, as iodine is essential for thyroid hormone production, and avoid excessive iodine consumption (>300 μg daily) as it can worsen thyroid function in some individuals, with common iodine sources including iodized salt, seafood, and dairy products 1
Include selenium-rich foods in your diet, such as Brazil nuts, fish, eggs, and whole grains, as selenium is important for thyroid hormone metabolism 2, 3
Follow an anti-inflammatory diet rich in fruits, vegetables, lean proteins, and healthy fats, and choose foods with high antioxidant content to reduce inflammation that may affect thyroid function, as recommended by the American Heart Association 4

Focus on a balanced diet with appropriate caloric intake (adjust based on metabolic needs), consume high-fiber foods to improve satiety and digestive function, and track weight, physical activity, and calorie intake to maintain healthy weight, as suggested by the American Heart Association 4

Limit intake of refined sugars and highly processed foods, and choose whole foods over processed options to reduce inflammation, as recommended by the American Heart Association 4
Include sources of omega-3 fatty acids (fatty fish, flaxseeds, walnuts), and use liquid vegetable oils instead of solid fats, as suggested by the American Heart Association 4

Consider vitamin D supplementation if levels are low, as vitamin D deficiency is common in hypothyroidism, according to the National Kidney Foundation 5, 6
Consider zinc supplementation (15 mg/day) if deficient, as zinc supports thyroid function, as recommended by the Clinical Nutrition society 7
Selenium supplementation (50-70 μg/day) may be beneficial for some patients with autoimmune thyroiditis, according to the Clinical Nutrition society 7

Always take thyroid medication on an empty stomach, at least 30-60 minutes before eating, as recommended by the American Medical Association 8
Be cautious with kelp and seaweed supplements, which can contain excessive amounts of iodine, as warned by the Clinical Nutrition society 1

Maintain consistent meal timing to help regulate metabolism, as suggested by the American Heart Association 4
Take thyroid medication at the same time each day, typically in the morning before breakfast, as recommended by the American Medical Association 8

Regular monitoring of thyroid function is essential when making dietary changes, and work with healthcare providers to adjust medication dosage as needed, as recommended by the American Medical Association 8
