Just like you might eat certain foods for your brain or heart, there are specific foods that can support the proper functioning of your thyroid. Selecting the right foods for thyroid can go a long way in improving the general wellbeing of an individual.

One should ensure that one eats right to keep this small but essential gland in a good state.

Some people worry about soy and thyroid health. They think soy might change thyroid hormone levels. But a big 2019 study looked at many smaller studies about this. It found that eating soy didn't actually affect thyroid hormones.

So, while we're not completely sure, current research suggests soy is probably safe for most people's thyroids. When thinking about food good for thyroid, soy seems to be okay for most people.

2. Berries

Eating right for your thyroid isn't just about iodine, selenium, and vitamin D. Foods with lots of antioxidants are also good for your thyroid. Antioxidants are things in food that fight cell damage. A 2022 study found that antioxidants can help when your thyroid isn't working well.

So, when looking for food good for the thyroid, think about including antioxidant-rich foods in your diet too. These might include colorful fruits and vegetables, nuts, and certain herbs and spices. A balanced diet with a variety of nutrients can support overall thyroid health.

3. Eggs

Eggs are great for thyroid patients. One big egg has about 16% of the iodine and 20% of the selenium you need each day. These nutrients are important for your thyroid. Most of this goodness is in the yolk, so eat the whole egg unless your doctor says not to.

This makes eggs one of the best foods for thyroid patients. They're like a superfood for your thyroid health. Remember, always follow your healthcare provider's advice about what to eat.

4. Shellfish

Shellfish like lobster and shrimp are healthy thyroid food. They're rich in iodine, which your thyroid needs. Just 3 ounces of shrimp (about 4 or 5 pieces) gives you 10% of the iodine you need daily. But that's not all - shellfish are also good for zinc. 

For example, 3 ounces of Alaskan crab has 6.5 milligrams of zinc, while the same amount of lobster has 3.4 milligrams. Zinc is another nutrient that helps your thyroid work well. So, adding shellfish to your diet can be a tasty way to support your thyroid health. Remember, variety is key when choosing the best thyroid food.

5. Chicken and Beef

Zinc is very important for thyroid patients. Your body needs it to make thyroid hormone. Not getting enough zinc can lead to hypothyroidism, where your thyroid doesn't work well. Interestingly, having hypothyroidism can also make you low in zinc. This can cause problems like hair loss.

Good food for thyroid patients includes zinc-rich options. Beef is a great source - a 3-ounce beef chuck roast has 7 milligrams of zinc. A beef patty of the same size has 3 milligrams. Even dark chicken meat is good, with 2.4 milligrams in a 3-ounce serving. Adding these foods to your diet can help support your thyroid health. 

6. Milk

Milk and dairy products are great thyroid healthy food. They're packed with iodine, which your thyroid needs. One cup of low-fat milk gives you about one-third of your daily iodine needs. It's even better to choose milk with added vitamin D.

This is because people with an underactive thyroid often don't have enough vitamin D. Be aware that plant-based milk alternatives like soy or almond milk usually don't have much iodine. If you're looking for thyroid healthy food, regular milk can be a good choice. It supports your thyroid in two ways - with iodine and vitamin D.

7. Yogurt

Dairy products are good for your thyroid gland. They contain iodine, which your thyroid needs. On average, one cup of dairy has about 85 micrograms of iodine. But this can vary. For example, nonfat milk can have anywhere from 38 to 159 micrograms per cup.

This variation happens because farm animals get iodine supplements, and the milking equipment is cleaned with iodine-based products. When thinking about what food is good for thyroid gland, dairy is a safe choice.

You don't have to worry about getting too much iodine from regular foods like milk. Only seaweed products like kelp might give you too much.

8. Brazil Nuts

Brazil nuts are among the best food for thyroid patients. They're rich in selenium, a nutrient that helps control thyroid hormones. Selenium might protect your thyroid from long-term damage, especially if you have conditions like Hashimoto's or Graves' disease.

Just one Brazil nut has between 68 and 91 micrograms of selenium. That's a lot! But be careful not to eat too many. The daily limit for selenium is 400 micrograms. So, while Brazil nuts are great for your thyroid, stick to just a few per day. 

9. Fish

Fish is great food to support thyroid health. It's rich in iodine, which your thyroid needs to work well. Iodine is found in the sea, so seafood is naturally high in it. People who live far from the ocean and don't eat seafood can have thyroid problems.

A 3-ounce serving of baked cod has about 158 micrograms of iodine. That's enough to meet your daily needs if you're not pregnant or breastfeeding. Adding fish to your diet is an easy way to get this important nutrient. It's a tasty option when looking for food that supports thyroid.

10. Cruciferous Vegetables

Cruciferous vegetables like broccoli, cauliflower, kale, and Brussels sprouts are actually thyroid good food, despite some online claims. These veggies contain compounds called glucosinolates, which some worry might affect thyroid hormone production.

But eating normal amounts is safe and healthy. It would take eating huge amounts – like over 1 kg (2.2 pounds) daily for months – of raw kale, collards, or Brussels sprouts to cause any thyroid issues. Regular servings of these veggies are fine and can be part of a healthy diet for most people with thyroid conditions.

11. Avocado

What Foods to Avoid?

For a healthy thyroid, knowing what foods to avoid is just as important as knowing what to eat. Some foods can make your thyroid work less well. This guide will tell you about three types of foods that might not be good for your thyroid. If you have thyroid problems, or want to keep your thyroid healthy, it's smart to be careful with these foods.

Eating the right foods and avoiding others can help your thyroid work better, which is good for your overall health. Let's look at thyroid what foods to avoid to keep your thyroid working its best.

1. Gluten

This limitation primarily applies to people with celiac disease or gluten intolerance. Research from 2021 suggests a significant connection between celiac disease and autoimmune thyroid conditions like Hashimoto's thyroiditis and Graves' disease.

This relationship, known as the thyroid-gut-axis, indicates that gut microorganisms can influence the immune system, nutrient absorption, and thyroid function. While it's uncertain if a gluten-free diet alone can treat thyroid disease, those diagnosed with celiac disease should strictly avoid gluten to manage their symptoms effectively.

2. Processed Foods

Increasing your intake of salty, processed foods in an attempt to consume more iodine is not advisable. Manufacturers rarely use iodized salt in their products, meaning you may consume excess sodium without the benefits of iodine. High sodium intake can lead to health issues such as high blood pressure and heart disease.

3. Fast Food

Like processed foods, fast food chains are not required to use iodized salt. The American Thyroid Association (ATA) recommends avoiding restaurant foods as it's difficult to determine which establishments use iodized salt.

A study by the United States Department of Agriculture (USDA) found that fast food hamburger patties contain less iodine than non-fast food ground beef patties. Specifically, a fast food hamburger patty contained 3.3 mcg of iodine per 100g, while a non-fast food ground beef patty contained 8 mcg of iodine per 100g.
