Five food groups—cruciferous vegetables, soy products, gluten-containing grains, excess iodine-rich foods, and processed sugary items—were flagged on World Thyroid Day 2026 as potential disruptors of thyroid management.
The advice varies by condition: goitrogens in broccoli, cabbage and kale may hinder iodine absorption in hypothyroidism, while seaweed, kelp and too much iodized salt can further stimulate hormone production in hyperthyroidism.
Soy foods such as tofu and soy milk may reduce thyroid medication absorption, prompting experts to recommend a time gap between eating them and taking treatment.
The awareness push also highlighted that gluten may aggravate autoimmune thyroid disorders like Hashimoto’s in sensitive people, reinforcing earlier guidance to pair treatment with careful diet management.
