Five nutrition moves to support thyroid health before World Thyroid Day 2026

Dr. Ramesh Kinha outlines five nutrition-based strategies to protect thyroid health ahead of World Thyroid Day (May 25, 2026): follow a Mediterranean (and Paleo-style unprocessed) diet rich in fruits, vegetables, whole grains, healthy fats and lean proteins while limiting large amounts of raw cruciferous vegetables; ensure iodine intake through iodised salt and foods like seaweed, dairy, seafood and eggs with caution for autoimmune thyroid disease; include selenium-rich foods (tuna, eggs, Brazil nuts, legumes, sardines, oats) in moderation to protect the thyroid from oxidative stress; optimize zinc intake (pumpkin seeds, oysters, nuts, lentils) with moderation; boost vitamins D and B12 and minerals iron and magnesium from sunlight, animal products and plant foods, pairing citrus with iron to improve absorption. Also avoid ultra-processed foods; for hyperthyroidism, moderate iodine, caffeine, soy and gluten as advised; combine good nutrition with regular exercise, sufficient sleep and stress management for better thyroid health.
