When your thyroid isn’t functioning as it should, it doesn’t produce the right amount hormones you need. These hormones regulate your energy levels, metabolism, body temperature, mood, heart rate, and blood pressure. The most common thyroid problems are hyperthyroidism (high thyroid) and hypothyroidism (“low thyroid”) Certain foods help your thyroid function at peak efficiency if you’re worried about hyperthyroidism. They include the following. Low-Iodine Foods * Non-iodized salt * Coffee or tea (without milk or dairy- or soy-based creamers) * Egg whites * Fresh or canned fruit * Unsalted nuts and nut butters * Oats * Potatoes * Honey and maple syrup Cruciferous Vegetables * Broccoli * Brussels sprouts * Cauliflower * Collard greens * Kale * Mustard Foods That Contain Healthy Fats * Unsalted nuts and seeds * Avocado and avocado oil * Olive oil * Coconut oil * Sunflower oil * Safflower oil Spices Some spices and herbs like turmeric, green chilies, and black pepper have antioxidants and anti-inflammatory properties that protect and balance thyroid function. Foods that are good if you’re concerned about hypothyroidism include these. Baked fish Salmon, cod, sea bass, haddock, or perch are rich in omega-3 fatty acids and selenium, which both help the thyroid. Certain dairy products Frozen yogurt, ice cream, and milk contain iodine, which your thyroid needs to prevent the gland enlargement known as goiter. Low-fat servings help you get the iodine you need. Fresh eggs Eggs contain healthy amounts of both selenium and iodine. It’s best if you eat the whole egg, as the yolk holds most of the nutrients. Salted nuts Brazil nuts, macadamia nuts, and hazelnuts are excellent sources of selenium.
