15 Iodine Rich Foods For Pregnancy

15 Iodine Rich Foods For Pregnancy

Iodine is a mineral directly responsible for proper thyroid functioning, which is critical for a healthy pregnancy. The thyroid produces hormones that help regulate metabolism, heart health, and fetal development during pregnancy. These thyroid hormones also repair damaged cells and influence bone and brain development in pregnancy. Believe it or not, this mineral is responsible for MANY functions in the body.

Pregnant women should strive to consume 220 micrograms of iodine every day. While iodine deficiency is rare in the US, pregnant women are advised to monitor their iodine intake. Iodine deficiency during pregnancy can result in severe problems for mother and baby, including underdeveloped thyroid and impaired neurodevelopment. As well as increased risk of miscarriage, prematurity, stillbirth, and low birth weight.

So, how can you ensure you’re consuming enough iodine during pregnancy? The best way to ensure you’re getting plenty of iodine during those nine months is to eat iodine-rich foods! You can also find well-rounded prenatal vitamin supplement options that include iodine in their list of nutrients.

However, before starting any new supplement, it’s essential to speak with your doctor or dietitian first. We review all the details on prenatal vitamins, including the pros and cons of specific brands inside The Prenatal Nutrition Library, to help you find the best option for you!

Because strawberries are ~91% water, they are excellent for helping expecting mothers stay hydrated, especially during the warm months.

Prunes

Dried prunes are a great snack during pregnancy and delicious addition to any snack plate or trail mix. While prunes contain a fair amount of iodine, they are most known for their rich fiber content. They can help expecting mothers ward off common pregnancy symptoms, such as constipation, irregularity, and hemorrhoids. That said, consuming prunes in moderation is essential to avoid an upset stomach and with plenty of fluids to prevent constipation.

Cranberries

Cranberries contain a TON of iodine, with over 100% RDA in just one cup or less. While they are mostly made up of healthy carbs and fiber, they also contain vitamin C and antioxidants.

Iodine content: 400 mcg/ 1 cup raw or ¼ cup dried

Baked Potato

Baked potatoes, or more specifically, the skin on baked potatoes, is a source of iodine. Surprisingly, baked potatoes are also a source of vitamin C, with around 12% RDA for pregnant women. Baked potato topping choices are endless, from beans to shredded chicken, butter, or salsa. Since iodine is found in dairy products and iodized salt, adding a bit of these two toppings can increase the iodine content.

Cod

Cod is a high-quality and low mercury fish choice making it a safe seafood option to consume during pregnancy as long as it is thoroughly cooked and sourced from a reputable distributor.

Add shrimp to your next pasta, stir-fry, salad, or soup. YUM!

The last fish on our list today is tuna. Canned or fresh, tuna is a good source of iodine. Keep in mind that there are a variety of types of tuna. Skipjack is a low mercury tuna option safe for pregnancy, whereas ahi tuna is a higher mercury choice and recommended to skip during pregnancy. Just three oz. of tuna contains about ten mcg of iodine and a whopping 24 grams of protein.

Plus, tuna is super versatile. You can add tuna to almost any salad, whip up a tuna salad sandwich, or serve tuna “cakes”/burgers with your favorite sides. We recommend asparagus and brown rice!

Seaweed

Seaweed is one of the most iodine-rich foods on Earth. The amount of iodine varies depending on the type of seaweed. Many types of seaweed are safe for consumption during pregnancy, including Nori. However, the seaweed variety that contains the most iodine is Kombu Kelp. Iodine is an essential nutrient, but it is possible to get too much. Besides iodine, some seaweed is rich in iron (spirulina), fiber, protein, calcium, and magnesium. Enjoy seaweed on your next salad or with sushi options safe for pregnancy.

Iodized Salt

As the name suggests, iodized salt (table salt) is an excellent source of iodine. While we don’t recommend getting your RDA of iodine solely through salt, it can be a great way to up your iodine levels quickly and easily, especially if you find that you regularly lack iodine. Sodium (salt) is essential for many reasons, including blood pressure regulation, fluid balance, and prevention of dehydration. Sprinkle salt over your next baked potato for iodine win-win!

Iodine content: 45 mcg/ 1 gram

Consuming plenty of iodine is vital for the health of both mother and baby.

Iodine is responsible for many bodily processes AND is involved in the proper growth and development of baby. So, add these foods to your pregnancy shopping list today to ensure both you and baby get the nutrients you need for a happy and healthy pregnancy.

Remember that just like an iodine deficiency can be dangerous, an excess can also be hazardous. While rare, excess iodine intake can cause nausea, vomiting, diarrhea, and in extreme cases, delirium, stupor, and shock. So, be sure to consume iodine-rich foods in moderation!
