Hypothyroidism Diet – Foods To Eat

Hypothyroidism can lead to a disrupted menstrual cycle, weight gain, constipation, goiter, depression, dry skin, hair fall, muscle fatigue, slow heart rate, high blood cholesterol, and a puffy face. Apart from medicines, you can consume these foods to boost your thyroid function.

1. Iodized Salt

According to the American Thyroid Association, iodine is needed for the production of the thyroid hormone. Iodine deficiency can lead to hypothyroidism and goiter. Since your body cannot produce iodine naturally, you should eat foods that contain a good amount of iodine. And the best way to do that is to consume iodized salt.

2. Brazil Nuts

Brazil nuts are a great source of the mineral selenium that helps catalyze the conversion of the inactive thyroid hormone to the active form. Scientists have found that Brazil nut supplementation improved thyroid hormone levels.

Selenium also helps reduce inflammation and inhibits cancer cell proliferation. You can consume up to 8 Brazil nuts per day. Do not eat too many as it may lead to nausea, diarrhea, and vomiting.

3. Fish

Fish are rich in omega-3 fatty acids and selenium. Omega-3 fatty acids help lower LDL cholesterol, and selenium keeps your thyroid hormone kicking. Consume salmon, sardines, and tuna to counteract hypothyroidism. You can have 3-5 oz fish every day. Make sure not to overcook the fish.

4. Bone Broth

Consume a cup of bone broth for lunch or dinner. Toss in some vegetables. Make sure to cook the vegetables properly. Raw cruciferous vegetables like cabbage, cauliflower, turnip, and brassica seeds contain goitrin, an active goitrogen that reduces thyroid hormone secretion . However, proper cooking destroys the goitrogen factor.

5. Vegetables And Fruits

Green leafy vegetables, colorful vegetables, and fruits are great sources of minerals, vitamins, antioxidants  , and dietary fiber. However, you should be careful if you have hypothyroidism because a few veggies and fruits can hinder the production of the thyroid hormones and are known as goitrogens.

Vegetables such as cauliflower, spinach, kale, broccoli, cabbage, radish, sweet potato, peach, avocado, and mustard greens are goitrogens. However, cooking these veggies and fruits properly can render the goitrogens inactive.

6. Seaweed

They help upregulate the thyroid hormone production, uplift mood, prevent lethargy, and improve brain function. You can have up to 150 mcg of seaweed per day.

7. Dairy

Low-fat milk, yogurt, and cheese are rich in iodine and selenium that help boost thyroid hormone production and activation. They are also rich in the amino acid tyrosine that helps combat the symptoms of hypothyroidism like depression and fatigue .

Have a glass of milk, half a cup of yogurt, and ⅙ cup of cheese per day to increase the thyroid hormone levels.

8. Beef And Chicken

Your thyroid function can also be accelerated by providing your body with the required amounts of zinc. It is mostly found in beef and chicken and can help convert triiodothyronine (T3) to thyroxine (T4). This conversion is of great importance because T3 is the inactive form while T4 is the active form of the thyroid hormone. Consume at least 3 oz of chicken breast or lean cuts of beef to boost thyroxine production. Zinc supplementation also improves the hormonal balance.

9. Eggs

Eggs, especially the yolk portion, are a great source of iodine and can help alleviate hypothyroidism. Include whole eggs 2-3 times in a week in your diet, depending on your lipid profile.

10. Shellfish

Shellfish like shrimp and lobster are packed with iodine and zinc. And, as you know, iodine and zinc can help boost the production of the thyroid hormone. Consume at least 3 oz shellfish to improve your thyroid levels.

11. Extra Virgin Coconut Oil

Virgin coconut oil contains high levels of lauric acid, a medium-chain triglyceride that is converted into monolaurin and has antimicrobial  and anti-inflammatory  properties and improves metabolism.

Add 1-2 tablespoons of extra virgin coconut oil to your smoothie or use it as a salad dressing.

12. Flax Seeds

Flax seeds are a great source of omega-3 fatty acids, zinc, selenium, and iodine. Flax seeds are also good for weight loss.

Add 2-3 tablespoons ground flax seeds to your smoothie or breakfast cereal, or use flax seed oil for cooking.

13. Legumes

Legumes are rich in iodine and zinc and are gluten-free . You can consume lentils, beans, bean sprouts, chickpeas, etc. to boost your thyroid gland hormone secretion.

14. Fiber-Rich Foods

Add fiber-rich foods to your diet because if you have hypothyroidism, chances are you also experience indigestion and constipation. Fiber helps improve bowel movement and digestion.

Include foods such as papaya, cooked green leafy veggies, and gluten-free whole grains to improve your digestion. Here’s a list of high-fiber foods for weight loss.

15. Water

Water helps hydrate your body and flush out toxins. Drink 3-4 liters of clean water per day to help your cells function properly. Though water may not directly help you tackle hypothyroidism, drinking enough of it can help your organs function properly.

These were the 15 foods you should consume if you have hypothyroidism. Here’s your diet chart.

Foods To Avoid To Treat Hypothyroidism

• Raw cruciferous vegetables like cabbage, cauliflower, turnip, etc.
• Gluten-containing foods.
• High-sugar foods as uncontrolled insulin spikes deteriorate the hypothyroidism condition.
• Junk food and processed foods, like deep-fried foods, batter-fried foods, potato wafers, French fries, etc. These foods have a truckload of sodium but no iodine or nutritional value. They will only increase the cholesterol levels and take a toll on your health.
• Green tea. There are many studies that have confirmed that green tea possesses anti-thyroid properties and consuming excessive green tea can cause hypothyroidism.

If you have an overactive thyroid, you must go on a hyperthyroidism diet. Here’s a list of foods you can eat:

Hyperthyroidism Diet – Foods To Eat

Hyperthyroidism leads to weight loss, increased heart rate, anxiety, irritability, irregular periods, bulging eyes, insomnia, difficulty in concentrating, increased hunger, and moist skin . Apart from your doctor prescribed medicines, certain foods can also help treat hyperthyroidism. Here’s the list.

1. Raw Fruits And Vegetables

Raw cruciferous vegetables or leafy greens are goitrogens, i.e., they inhibit the production of the thyroid hormones. This is exactly what you need as your thyroid is overactive.

Consume broccoli, spinach, kale, bok choy, cabbage, lettuce, Chinese cabbage, carrot, cauliflower, radish, collard greens, rocket spinach, Brussels sprouts, bell pepper, tomato, apple, berries, kiwi, orange, lemon, grapefruit, etc.

2. Millets And Brown Rice

Millets and brown rice also have high goitrogenic activity. They are a great source of dietary fiber, vitamins, and minerals. You can consume ½-1 cup brown rice or millets per day to suppress the overproduction of the thyroid hormone.

3. Lean Proteins

Have chicken breast, fish, mushroom, soy chunks, and legumes to help build lean muscle mass. Hyperthyroidism leads to an increased appetite and rapid weight loss. Since proteins take much longer to digest, they will keep you full for a longer duration.

4.  Herbs

Basil, oregano, and rosemary are anti-inflammatory in nature and can help alleviate the problem of hyperthyroidism.
