What You'll Learn
Iodine-rich foods: seaweed, seafood, dairy, eggs, and iodised salt
Iodine is a mineral that is naturally found in the sea and some soils. It is an essential micronutrient that the human body needs to function properly, but it cannot produce on its own. Therefore, iodine must be obtained through one's diet.
Iodine-rich foods include:
Seaweed
Seaweed is one of the best sources of iodine available. The iodine content varies depending on the species, with kombu kelp offering the highest amount. A 10-gram serving of dried nori seaweed provides up to 232 mcg of iodine, exceeding the daily required minimum by over 150%.
Seafood
Seafood is a great source of iodine. This includes certain types of fish, such as cod, tuna, and salmon. Seaweed and other seafood like shrimp, prawns, and oysters are also rich in iodine. It is recommended to eat seafood 2 to 3 times a week, but be mindful of the mercury content in certain fish like swordfish and tuna, especially if you are pregnant or breastfeeding.
Dairy
Dairy products like milk, yogurt, and cheese are major sources of iodine. An eight-ounce serving of nonfat cow's milk contains 85 mcg of iodine, contributing significantly to your daily iodine needs. Greek yogurt, due to its denser consistency, has an even higher concentration of iodine, providing up to 116 mcg per eight ounces.
Eggs
Eggs are another food item that contains iodine. They can be a good option for those looking to increase their iodine intake.
Iodised Salt
Iodine is commonly added to table salt, known as iodised salt. Using iodised salt is an important way to prevent iodine deficiency. However, it is recommended to consume salt in moderation, as excessive salt intake can increase the risk of heart disease and stroke.

Iodine supplements: 0.5mg or less daily is safe
Iodine is a mineral found in the earth that is essential to human health. It is not produced by the human body and must be obtained through diet. Iodine occurs naturally in seawater and is present in seafood such as seaweed, shrimp, and fish like tuna and cod. It is also found in dairy products like milk, yogurt and cheese, as well as iodized table salt.
Iodine is crucial for the proper functioning of the thyroid gland, a butterfly-shaped gland located in the front of the neck. Iodine deficiency can lead to an enlarged thyroid gland, a condition known as goiter, and hypothyroidism. However, excessive iodine intake, especially over long periods, can also negatively impact the thyroid, leading to similar issues as well as weight gain.
For adults, the recommended dietary allowance (RDA) of iodine is 150 mcg daily. During pregnancy, the RDA increases to 220 mcg, and while breastfeeding, it is recommended to consume 290 mcg daily. It is important to note that iodine intake above 1100 mcg daily for adults and 900 mcg for adolescents may be unsafe and could lead to thyroid problems.
To safely add iodine to your diet, consider the following:
- Include iodine-rich foods: Incorporate seafood like seaweed, shrimp, and fish; dairy products like milk, yogurt and cheese; and iodized salt in moderation into your meals.
- Take supplements cautiously: Iodine supplements can be taken, but it is crucial not to exceed the recommended dosage. Taking 0.5 mg or less daily is generally considered safe and unlikely to cause any harm. Always consult a healthcare professional before starting any supplement regimen.
- Seek professional advice: Discuss your specific needs and conditions with a healthcare provider. They can advise on the appropriate type of iodine product and dosage suitable for you.
In summary, while iodine is essential for health, it is important to maintain a balanced and varied diet that includes iodine-rich foods. By doing so, you can safely meet your iodine requirements without relying solely on supplements.

Iodine deficiency: rare in the US, common elsewhere
Iodine is a mineral found in the earth. It is not produced by the human body and must be obtained through diet. Iodine deficiency occurs when there is insufficient iodine in the diet. This can lead to an enlarged thyroid gland, a condition called goiter, and hypothyroidism. While iodine deficiency is rare in the United States, it is prevalent in other parts of the world, particularly in developing countries and specific regions.
In the United States, iodine deficiency used to be common in certain areas. However, since the introduction of iodized salt in 1924, the rates of iodine deficiency have dropped significantly. Iodized salt is table salt that has been fortified with iodine. It is important to note that not all salts are iodized, and some specialty salts such as sea salt, kosher salt, and Himalayan salt do not contain iodine. Therefore, it is recommended to use iodized salt when cooking or seasoning food to ensure adequate iodine intake.
In addition to iodized salt, iodine can be found naturally in some foods, especially seafood. Seaweed, shrimp, and other seafood are excellent sources of iodine. Certain types of fish, such as cod and tuna, are also good sources. Dairy products, including milk, yogurt, and cheese, can provide iodine as well. However, this depends on the diet of the dairy cows, as iodine content in dairy can be affected by the use of iodine-based disinfectants or the addition of iodine to cow feed.
Iodine deficiency is particularly common in regions far from water sources or at higher altitudes, where access to seafood and iodine-fortified dairy may be limited. Additionally, in some areas, iodine is not added to table salt, further contributing to iodine deficiency. Globally, it is estimated that iodine deficiency resulting in goiter affects approximately 187 million people, with certain regions severely affected, including the Western Pacific, Southeast Asia, and Africa.
To safely add iodine to your diet, it is important to understand the recommended daily intake, which is typically around 150 micrograms for adults. Pregnant and breastfeeding women have higher requirements, advised to take a prenatal vitamin containing 250 micrograms of iodine daily. Iodine supplements are also available, but it is important to consult a healthcare provider before taking any supplements. Including iodine-rich foods in your diet, such as seafood, dairy, and iodized salt, can help prevent iodine deficiency and ensure adequate iodine intake.

Iodine's role: thyroid health, metabolism, brain health
Iodine is a mineral found in the earth. It is not produced by the human body and must be obtained through diet. Iodine is necessary for the thyroid gland to produce thyroid hormones. These hormones are essential for regulating metabolism and ensuring the healthy functioning of the heart, brain, and other organs. An adequate amount of iodine in the body ensures that metabolic processes run smoothly.
The thyroid gland, located in the front of the neck, absorbs iodine from the bloodstream and incorporates it into the structure of triiodothyronine (T3) and thyroxine (T4). These hormones are key players in maintaining energy levels, growth, and a smooth-running metabolism. A lack of iodine means the thyroid cannot produce these hormones, leading to health issues.
Iodine deficiency is rare in the United States but common in developing countries and areas far from water or at higher altitudes. It can lead to an enlarged thyroid, hypothyroidism, and other thyroid-related issues. The best way to prevent iodine deficiency is to consume iodine-rich foods such as seafood, dairy, iodized salt, eggs, and certain plants from iodine-rich areas. Sea vegetables like kelp and nori are particularly good sources of iodine and are often recommended as supplements for those at risk of deficiency.
While iodine is crucial for thyroid health, excessive intake can lead to hyperthyroidism, autoimmune thyroiditis, and other thyroid issues. It is important to maintain optimal iodine levels by being aware of dietary habits and, if necessary, consulting a healthcare provider about iodine supplementation.

Iodine-fortified foods: bread, salt, dairy
Iodine is an essential mineral that must be obtained through one's diet as the body does not produce it on its own. Iodine is crucial for the proper functioning of the thyroid gland, which relies on it to produce thyroid hormones. Iodine deficiency can lead to health issues such as an enlarged thyroid, hypothyroidism, fatigue, muscle weakness, and weight gain.
One way to ensure adequate iodine intake is to consume iodine-fortified foods. Bread is one such example. While there is limited information on the specific iodine content of bread, it is included as a potential staple food vehicle for iodine fortification in public health programs. This suggests that consuming bread with added iodine may be a viable way to increase iodine intake.
Salt is another well-known example of an iodine-fortified food. Iodized salt has been widely used since the early 1920s to address iodine deficiency, particularly in the United States and Canada. Iodine fortification of salt has proven to be an effective strategy, as evidenced by the decrease in iodine deficiency rates. By adding iodized salt to your meals during cooking or at the table, you can significantly contribute to your daily iodine intake. However, it is worth noting that not all types of salt, such as sea salt, kosher salt, and Himalayan salt, are iodized.
Dairy products, including milk, yogurt, and cheese, are also sources of iodine. The iodine content in dairy can vary, but these foods are considered major providers of iodine in the American diet. Consuming dairy products can help maintain adequate iodine levels and prevent potential deficiencies.
In addition to these iodine-fortified foods, other natural sources of iodine include seafood (such as shrimp, tuna, and cod), seaweed, eggs, and certain fruits and beans. It is important to include these iodine-rich foods in your diet or consider taking iodine supplements to maintain optimal iodine levels and support thyroid health.
