Gluten is found in:
Wheat, barley, rye
Many breads, pastas, baked goods
What to do instead: If you suspect gluten sensitivity, talk with a healthcare provider and consider testing. A gluten-free diet may improve symptoms for some individuals.
5. Caffeine and Alcohol
Coffee and other caffeinated beverages can interfere with the absorption of thyroid medication if taken too close to your dose. Alcohol can also disrupt hormone production and metabolic balance.
When to consume: Wait at least 30–60 minutes after taking thyroid medication before drinking coffee or caffeinated tea.
6. High-Iodine Supplements and Seaweed When Overdone
Iodine is essential for thyroid hormone production, but too much iodine—especially from supplements or seaweed—can worsen thyroid disorders.
Examples of high-iodine sources:
Kelp or seaweed supplements
Certain marine foods in very large amounts
Excessive iodized salt
Why it matters: Both hypothyroidism and hyperthyroidism can be negatively affected by too much iodine intake.
What to do instead: Aim for balanced iodine consumption through food and check with your doctor before using supplements.
Final Thoughts
Food doesn’t cause thyroid disease on its own—but certain eating patterns can make symptoms harder to manage or interfere with treatment. Always talk with a healthcare provider or registered dietitian before making big changes to your diet, especially if you take medications or have an autoimmune thyroid condition.
