Thyroid conditions affect the metabolism directly. Conditions such as hypothyroidism and hyperthyroidism are managed by your doctor, and the way you eat can be a supportive part of that care. Here are general nutrition points often discussed for people with thyroid conditions. Because the right choices differ greatly between conditions (for example, iodine needs differ), please agree your own plan with your doctor and dietitian:
1. Nutrients That Support Thyroid Health
The thyroid uses certain nutrients to work normally, and a varied diet helps provide them.
Foods Containing Iodine
- Seaweed (nori, wakame, kombu)
- Iodised salt
- Fish and seafood
- Eggs
Both too little and too much iodine can be a problem, so do not take iodine supplements or large amounts of seaweed unless your doctor has advised it.
Sources of Selenium
- Brazil nuts
- Sunflower seeds
- Salmon and tuna
- Wholegrains
Foods Containing Zinc and Iron
- Red meat and turkey
- Pumpkin seeds
- Dark green leafy vegetables
- Lentils
2. Foods to Moderate
Some foods may interfere with how the thyroid works when they are eaten in large amounts.
Foods Containing Goitrogens (Not to Be Eaten in Excess)
- Cabbage, broccoli, cauliflower
- Soya and soya-based products
- Turnip and radish
- Brussels sprouts
Refined and Processed Foods
- Refined flour and white bread
- Packaged snacks
- Sugary drinks
3. An Example Daily Eating Plan (to Review with Your Dietitian)
| Meal | Foods |
| Breakfast | Eggs, wholegrain bread, avocado, green tea |
| Snack | Brazil nuts and yoghurt |
| Lunch | Grilled salmon, quinoa pilaf, vegetables cooked in olive oil |
| Snack | Pumpkin seeds and a banana |
| Dinner | Chicken breast, lentil soup, spinach salad |
| Evening snack | Almond milk and cinnamon apple slices |
4. Extra Suggestions
- Drink water regularly: A commonly given guide is 2 to 3 litres a day, unless your doctor has advised otherwise.
- Limit caffeine: Too much coffee can affect how some people feel, and it can interfere with the absorption of thyroid medicine, so ask your doctor about timing.
- Stay active: Gentle walks and yoga support general wellbeing, once your doctor has said they are suitable for you.
- Manage stress: Meditation and breathing exercises may help you cope with stress.
A thoughtful eating plan can be a supportive part of caring for a thyroid condition. Eating foods that contain iodine, selenium, zinc and iron in sensible amounts, limiting processed foods and adopting a healthy lifestyle are often discussed as part of it. Results vary from person to person, and nutrition never replaces medical treatment, so please agree your own plan with your doctor and dietitian.
