Best and Worst Foods for Thyroid Health
If you have a thyroid condition—such as Hashimoto’s, hypothyroidism, or hyperthyroidism—certain foods can support thyroid function, while others may worsen symptoms. Although this is not a complete list, the following guide highlights a few key foods that may help support thyroid health, as well as those that can interfere with it. Best foods for thyroid health: ✅ 1. Selenium-Rich Foods Selenium is essential for converting T4 → T3, the active thyroid hormone. Best sources: · Brazil nuts (1–2/day is plenty) · Tuna, sardines · Eggs · Sunflower seeds · Turkey ✅ 2. Iodine-Rich Foods Iodine is required for the thyroid gland to make hormones—but balance is key. Best sources: · Seaweed (kelp, nori, wakame) · Iodized salt · Eggs **Note: Excess iodine can worsen Hashimoto’s in some people. ✅ 3. Zinc-Rich Foods Zinc supports hormone production and immune function. Best sources: · Oysters · Beef, chicken · Chickpeas · Pumpkin seeds ✅ 4. Anti-Inflammatory Foods Great for autoimmune thyroid issues (Hashimoto’s). Best sources: · Fatty fish (salmon, mackerel, sardines) · Extra-virgin olive oil · Turmeric, ginger · Leafy greens · Berries ✅ 5. High-Fiber Foods Supports digestion and helps regulate metabolism. Best sources: · Oats, quinoa · Beans, lentils · Veggies and fruits of all kinds ✅ 6. Probiotic Foods Gut health strongly influences thyroid function. Best sources: · Yogurt (with live cultures) · Kefir · Sauerkraut · Kimchi ⚠️ Worst Foods for Thyroid Health ❌ 1. Excess Goitrogenic Foods (Raw Cruciferous Veggies) These foods can interfere with iodine uptake when eaten raw in large amounts. Examples: · Raw broccoli · Raw cauliflower · Raw kale, cabbage **GOOD NEWS: Cooking reduces goitrogens by ~70–80%, so cooked versions are totally fine for most people. ❌ 2. Gluten (for Hashimoto’s or suspected sensitivity) Gluten can increase inflammation and antibody activity in many people with autoimmune thyroid disease. Some notice improved energy, digestion, and antibody reduction after reducing or eliminating gluten.
