Salt
1 / 9

Salt

Your thyroid needs iodine to work well. Most people in the U.S. get enough of this element from their diet, usually through fish and dairy products. Make sure you’re using iodized table salt at home. You can tell by looking at the label.

Leafy Greens

Spinach, lettuce, and other leafy greens are great sources of magnesium, an all-star mineral that plays a huge role in your body processes. Fatigue, muscle cramps, and changes in your heartbeat could be signs that you're not getting enough.

Assorted nuts

Nuts

Cashews, almonds, and pumpkin seeds are excellent sources of iron. Brazil nuts help your thyroid in two ways. Not only are they a good source of iron, but they're also rich in selenium, another mineral that supports your thyroid. Just a few each day give you the selenium you need.

Seafood

Fish, shrimp, and seaweed are great sources of iodine. You need iodine for a healthy thyroid, but avoid large amounts of iodine-rich choices like kelp. That may make your condition worse.

fresh kale
5 / 9

Kale

Could kale, that superstar among superfoods, actually not be quite so awesome? Kale is a mild goitrogen -- in rare cases it prevents the thyroid from getting enough iodine. But kale shouldn't be a problem for you unless you get very little iodine in your diet and you’re eating large amounts of kale. This is also the case for cabbage, broccoli, cauliflower, and Brussels sprouts.

Soybeans

Soy

In rare cases, some of the chemicals found in soy products like soy milk or edamame could hurt your thyroid’s ability to make hormones, but only if you don't get enough iodine and eat large amounts. Just like with kale, if your iodine levels are OK, you probably don’t need to worry about soy.

Organ Meats

If you eat things like kidneys, heart, or liver, you might get a lot of lipoic acid. That's a fatty acid found in these and some other foods. You can also buy it as a supplement. But if you get too much, it could mess with the way your thyroid works. Lipoic acid could also affect any thyroid medicines you take.

Gluten and Your Thyroid

Gluten is a protein found in wheat, rye, and barley. Unless you've been diagnosed with celiac disease, it probably won’t affect your thyroid. Gluten can damage the small intestines of people with celiac disease. They can have other autoimmune disorders like Hashimoto’s disease (which leads to an underactive thyroid) and Graves' disease (which leads to an overactive thyroid). If you have celiac disease, a gluten-free diet may help prevent these thyroid diseases.

Thyroid Medication and Your Food

The foods you eat can affect your thyroid medicine. They can slow down how your body absorbs medicine. It can also affect how well it does it.

  • Take medicine on an empty stomach, preferably in the morning.
  • Some vitamins and antacids can also prevent your medicine from working.
  • Ask your doctor or pharmacist for more information about timing your food and other meds around your thyroid treatment.
