Iodine is an essential trace mineral crucial in the functioning of the thyroid gland, an organ that stores the minerals needed for the synthesis of our thyroid hormones. It is important to get adequate amounts of iodine in your diet to ensure the proper functioning of this vital gland which controls much of our metabolism, detoxification, growth and development.
Research has shown that a lack of iodine foods in your diet may lead to enlargement of the thyroid gland, lethargy, fatigue, weakness of the immune system, slow metabolism, autism, weight gain and possibly even mental states such as anxiety and depression.
The good news is that there are many popular foods with iodine, all of which are easy to incorporate into your daily diet.
The Recommended Daily Allowance (RDA) for iodine is 150 micrograms daily for everybody over the age of 14. The RDA for children ages 1-8 is 90/mcg every day, ages 9-13 is 120/mcg every day. If you’re pregnant or breastfeeding, it is recommended that you get 290/mcg every day.
The following list will discuss the top foods with iodine.
1. Sea vegetables
The ocean hosts the largest storehouse for iodine foods, including Kelp, Arame, Hiziki, Kombu, and Wakame. Kelp has the highest amount of iodine on the planet and one serving offers 4 times more than a daily minimum requirement. 1 tablespoon of Kelp contains about 2000/mcg of iodine, 1 tablespoon of Arame contains about 730/mcg of iodine, 1 tablespoon of Hiziki contains about 780/mcg of iodine, 1 one inch piece of Kombu contains about 1450/mcg of iodine, 1 tablespoon of Wakame contains about 80/mcg of iodine. I recommend sprinkling them in soups or on salads.
This antioxidant-rich fruit is another great source of iodine. About 4 ounces of cranberries contain approximately 400/mcg of iodine. I would recommend buying fresh organic berries or juice. If you buy cranberry juice from the store, be cautious of how much sugar is in it.
3. Organic Yogurt
A natural probiotic, yogurt is an excellent iodine food you should add to your diet. One serving holds more than half of your daily needs. 1 cup contains approximately 90/mcg of iodine. Other than yogurt, here is a list of probiotic foods you should think about incorporating into your diet for added health benefits.
4. Organic Navy Beans
Many beans are a great food source of iodine, but navy beans may top the list. Just 1/2 cup of these beans contain about 32/mcg of iodine. Beans aren’t just an iodine food, they are also incredibly high in fiber.
