Iodine Rich Foods

Iodine is necessary for the production of thyroid hormones, which are necessary for the regulation of metabolism as well as the performance of a wide variety of other tasks. In adults, a lack of it might cause mental cloudiness and a reduction in one’s capacity for logical thought. Is there a way to get out of this? Yes. Just making better food choices can be beneficial. For us to comprehend this, we need to take a look at how the thyroid gland works. This organ can be found in the front of the neck, directly beneath the voice box. The human body’s metabolism, as well as its expansion and growth, are all significantly impacted by its presence. This is accomplished through the gland’s secretion into the bloodstream of a constant quantity of thyroid hormones, specifically T3 and T4.

For the thyroid gland to perform at its best, it requires a proper amount of iodine. Its deficiency can result in an underactive thyroid, a condition in which the gland does not produce sufficient amounts of hormones. This results in effects that are not desirable. To make up for the lack of it, the thyroid gland will grow itself when it is deprived of it for an extended length of time, causing the condition known as goiter. Goiter is the medical term for this illness, which manifests itself in an unusually enlarged neck. Making sure you get enough of it in your diet is one method to reduce your risk of developing any of these conditions. Now, let’s take a look at the kinds of meals that are loaded with this nutrient.

We have put together a list of foods that are rich in iodine for you to peruse in this post.

What are Iodine rich foods?

It is really necessary to consume meals that are high in iodine. Its shortage can develop if one does not consume enough iodine daily; the most common issue that comes along with this condition is hypothyroidism. Hypothyroidism affects five out of every one hundred people in the United States, but the majority of instances are considered to be minor. Its shortage can become more prominent in more severe cases of the condition, which can lead to more obvious symptoms. In a situation like this, what options do you have? Iodine is required by the thyroid gland for it to be able to generate thyroid hormones, which are responsible for a variety of critical functions throughout your body.

For most adults, the amount of iodine that should be taken each day, according to the recommended daily intake (RDI), is 150 mcg. The standards are more stringent for women who are either pregnant or nursing mothers. One-third of the population is in danger of its deficiency. This is especially true for people who live in regions that have only a trace quantity of iodine in the soil, such as the countries in Europe. Iodine shortage can lead to goiter, also known as an enlarged thyroid gland, which can lead to discomfort, numbness or tingling, and excess weight. Goiter is the most common symptom of hypothyroidism. In this post, different food sources that are high in iodine and can help avoid its deficiencies are discussed.

Following are the Iodine rich foods


There are varying amounts of iodine in seaweed, but a single gram of it can provide anything from 11 percent to 1,989 percent of the recommended daily allowance. Supplementing with seaweed has been shown to improve iodine status, especially in iodine-deficient women. Thyroid hormone serum levels rose after treatment. In addition to being a good source of it, seaweed is tasty and can be eaten on its own. It just so happens that the Japanese have the highest iodine intake (from seaweed) per capita. Scientists think this explains why these people live so long and have such remarkably low rates of cancer.


Cod provides 66% of the recommended daily allowance for iodine with its 99 mcg per 3-ounce serving. It has a low fat and calorie content but a high iodine content. Contrarily, its content in cod varies depending on where it is caught. Omega-3s are particularly abundant in cod liver. Research suggests that it can assist avoid heart disease, however not as well as salmon or mackerel because of its lower omega-3 fatty acid content.


Iodine is an essential mineral, and one cup of milk provides 37% of the recommended daily allowance (RDA) of it. Milk is an important source of it. Research of 18 milk brands found that all of them had at least 88 mcg of iodine per eight ounces. Breast milk is a good source of it as well. It is supplied to infants by their mothers. Nutritional support for the maturation of the infant’s nervous system. Its concentration in 18 milk products commonly seen in the Boston area was analyzed in a recent study. There was at least 88 mcg in one cup (eight ounces) of milk across all 18 brands. To the tune of 168 mcg per cup, in the case of certain brands.

Iodine salt

The 71 mcg of iodine in just 1.5 g of iodized salt is enough to satisfy 47% of the recommended daily allowance. About 1920, governments around the world began iodizing their salt supplies. Iodine insufficiency was greatly reduced as a result of this. Iodized salt is now available to 90% of Americans. Today, iodizing salt is seen as a practical means of combating malnutrition. The maximum safe intake of it is 1,100 mcg, which is around four teaspoons (or 23 grams) of iodized table salt. Nonetheless, we advise against getting all your iodine from salt.


The iodine content in 3 ounces of prawn is 35 mcg, which is 23 percent of the recommended daily allowance. It is also abundant in this well-liked seafood.

Astaxanthin, a vital antioxidant that gives shrimp their signature red color, is also present in shrimp. Although beta-carotene is a powerful carotenoid, astaxanthin is more effective in neutralizing free radicals. Astaxanthin protects against heart disease when taken orally as a meal replacement. The iodine in seawater is absorbed by shrimp and other shellfish, making them a healthy supply of the mineral.


Tuna is a great source of it and protein while still being low in calories. It also contains beneficial nutrients like potassium, iron, and B vitamins. It is rich in omega-3 fatty acids, which have been shown to reduce cardiovascular illness risk. Generally speaking, fatty fish are not a good source of iodine. Tuna contains less of it than slimmer fish like cod because of its higher fat content. Despite this, tuna is still a rich source of it. Three ounces offer 17 mcg or roughly 11% of the RDI. Low-fat fish are the best source of iodine, scientists have found. Nonetheless, tuna is a fatty fish, thus having lower iodine than cod.


It is also found in sufficient amounts in eggs. One entire egg has less than 100 calories but is packed with protein, healthy fats, and a wide variety of micronutrients. Nevertheless, the yolk is where you’ll find the vast bulk of these nutrients, including iodine. It is added to chicken feed, so egg yolks are a terrific way to get your daily dose. However, the iodine concentration of eggs might vary from day to day due to variations in chicken feed. One large egg provides 16 percent of the RDI of it or 24 mcg. The egg’s yolk contains most of it. With one large egg, you can meet 16% of your daily needs. Eggs are among the healthiest foods available. Consuming eggs regularly was also proven to elevate “good” cholesterol. Research has shown that the egg yolk contains the vast bulk of the iodine in an egg.

In addition to this, they are an excellent source of iodine for vegetarians and vegans. The quantity of iodine that is found in soil, irrigation water, and fertilizers can all contribute to the variability in the iodine content that is found in veggies and fruits. On the other hand, one cup of cooked lima beans has an average of 16 mcg of iodine, which is equivalent to 10% of the daily intake.

The Bottom Line

The thyroid gland, which regulates growth and metabolism, requires enough levels of iodine to function properly. Because the human body is unable to produce iodine, it is crucial to consume iodine-rich foods. To prevent iodine deficiency, it is essential to include foods like seaweed, cod, dairy foods, iodized salt, prawn, mac n cheese, eggs, prunes, and lima beans in your daily diet.
