Hypothyroidism is one of the most common types of thyroid disorders, which reduces the production of thyroid hormones. It’s also known as an underactive thyroid, and it can cause weight gain that you didn’t mean to, sensitivity to cold, constipation, tiredness, muscle weakness, dry skin, and even depression. Along with necessary medications, altering your diet can help manage hypothyroidism symptoms. You can improve this condition by adding certain foods to your daily diet, particularly foods rich in iodine.
Iodine is an essential mineral needed for the production of thyroid hormones triiodothyronine (T3) and thyroxine (T4). These hormones help with enzyme activity, the creation of proteins, and the regulation of metabolism. Hypothyroidism can happen if your body doesn’t get enough iodine. This is because iodine affects the way thyroid hormones work. Since your body can’t make iodine on its own, eating foods that are high in it is the best way to increase the production of thyroid hormones and treat hypothyroidism. However, you should talk to a doctor before making big changes to your diet, because too much iodine can also be bad for you.
Here is a list of the five best foods that are high in iodine that people with hypothyroidism can eat every day.
Shrimp is one of the most popular seafood items around the world. Known for its delicious taste versatile cooking applications, and impressive nutrition profile shrimp is a staple ingredient in cuisines from Asia to the Americas. But when it comes to shrimp, one question that often comes up is does shrimp contain iodine?
In this comprehensive guide, we’ll explore the iodine content in shrimp, the health benefits and risks of iodine, how shrimp compares to other dietary sources, and what it means for certain groups like pregnant women and people with seafood allergies. Whether you love shrimp scampi, shrimp tacos, or classic shrimp cocktails, read on to get the full scoop on iodine levels in this crustacean favorite.
Iodine Content in Shrimp
Iodine is an essential trace element that is vital for human health. It plays a crucial role in thyroid hormone production, metabolism, growth, and development. The thyroid hormones triiodothyronine (T3) and thyroxine (T4) both contain iodine.
Shrimp, along with other seafood, does contain iodine. This is because shrimp and other marine life absorbs iodine from seawater through their diet and environment. On average, a 3-ounce serving of shrimp provides around 23% of the recommended daily iodine intake for adults. This amounts to approximately 35 micrograms of iodine per serving.
So in short – yes, shrimp does contain moderate levels of the important trace mineral iodine. Adding shrimp to your diet a few times a week can help support healthy iodine status.
Iodine Content Differences Between Shrimp Varieties
There are many popular varieties of shrimp, including:
- White shrimp
- Pink shrimp
- Tiger shrimp
- Rock shrimp
- Royal red shrimp
However, there is no significant difference in iodine content between these different types. Since they all live in ocean environments, absorbing iodine from the seawater, their iodine levels remain fairly consistent. The preparation method also does not alter the iodine content. So whether you opt for grilled shrimp, sauteed shrimp, or shrimp cocktail, you’ll be getting a similar amount of iodine.
Other Dietary Sources of Iodine
While shrimp provides a sizable portion of your daily iodine needs, there are other good food sources as well. These include:
- Fish like tuna, cod, and salmon
- Dairy products
- Eggs
- Seaweed
- Iodized salt
- Fortified cereals and grains
Of these, seaweed is one of the most concentrated sources due to its high absorption from seawater. Just one gram of many seaweed varieties can provide over 100% of your daily iodine needs.
Iodine and Shrimp Allergies
Some individuals may experience adverse reactions after eating shrimp due to an allergy. However, shrimp allergies themselves are not caused by iodine. Rather, they are triggered by proteins found in the shrimp tissue. Some people with iodine sensitivity may have reactions to the iodine content in shrimp, but this is less common.
People with shellfish allergies do not necessarily need to avoid shrimp specifically due to its iodine. But consulting an allergist is recommended to pinpoint your exact allergen triggers.
Is It Possible to Consume Excess Iodine from Shrimp?
Eating moderate amounts of shrimp as part of a balanced diet is not a concern for iodine excess. While shrimp does contain iodine, the levels are not high enough that regular consumption would push you over the safe upper limit. Consuming a variety of iodine-rich foods in moderation is recommended for optimal health.
However, if your diet is very high in multiple iodine-rich foods it could lead to excess iodine intake over time. Symptoms of iodine overconsumption can include throat irritation, stomach pain, nausea, vomiting, diarrhea, headache, and mouth sores. Those with underlying thyroid conditions may also need to monitor their shrimp intake.
Can Pregnant Women Eat Shrimp for Iodine?
Iodine needs increase during pregnancy due to fetal development and growth. The recommended daily intake goes from 150 micrograms up to 220 micrograms while pregnant.
Shrimp can be a healthy part of a balanced prenatal diet and contribute safe levels of iodine for pregnant women. However, it’s always best to check with your doctor about specific dietary suggestions during pregnancy. Some may recommend prenatal vitamins with iodine as well.
Cooking Method and Iodine Levels
Cooking shrimp through methods like boiling, grilling, sautéing, or baking does not significantly change the iodine content. Iodine levels remain stable through the cooking process. This also applies to frozen shrimp – the freezing process itself does not lower the iodine levels either.
Health Benefits of Iodine in Shrimp
Getting adequate iodine from the diet provides many important health benefits. These include:
-
Thyroid hormone production – Iodine is needed to make T3 and T4 thyroid hormones. These regulate your metabolism.
-
Growth and development – Thyroid hormones support growth, especially in infants and children.
-
Cognitive function – Thyroid hormones play a role in the development and function of the central nervous system and brain.
-
Pregnancy and fetal health – Iodine supports healthy fetal neurological and brain development.
So while shrimp tastes delicious, it also provides us with real nutritional benefits thanks to trace minerals like iodine.
Iodine vs. Iodized Salt
Table salt is often fortified with iodine, creating iodized salt. The iodine content is much higher in iodized salt compared to shrimp. Just 1/4 teaspoon of iodized salt provides about 70 micrograms of iodine.
While shrimp contains iodine naturally, salt is artificially supplemented. Both can be part of an overall healthy dietary pattern that meets your daily iodine needs.
Yoghurt, Milk & Cheese
If you want to know where to find the most bioavailable iodine, just look at dairy products. Yoghurt, milk and cheese are all major sources of this trace mineral. In addition, they are also loaded with healthy fats and calcium. The level of iodine content present in dairy products varies greatly. However, when it comes to cheese, mozzarella and cheddar have the highest amount of iodine.
Another excellent source of iodine is eggs. A large egg can contain up to 24 mcg of iodine. Eggs are also full of many other good things for you, like protein, iron, riboflavin, folate, and vitamins B12, D, and E. Keep in mind that the majority of the iodine content found in eggs comes from the yolk. So, if you only eat egg whites, you probably won’t get the benefits of iodine or the other nutrients they contain.
Youll find that sea vegetables serve as one of the richest naturally occurring sources of iodine. Seaweeds come in many forms, of which the most popular are kelp, wakame, Nori and Kombu. For example, kelp is full of iodine and also has B vitamins like riboflavin and pantothenic acid, which are both very good for people who are depressed or anxious because their thyroid isn’t working right. Furthermore, seaweed is also low in calories and rich in vitamins, minerals and antioxidants.
Like other seafood, shrimp is a good source of iodine because it soaks up some of the iodine that is naturally in seawater. Two and a half ounces of shrimp contain almost three hundred micrograms of iodine, which is about 23 percent of the daily recommended amount. In addition to being high in iodine, it is also quite low in calories. Moreover, it provides several other key nutrients like protein, selenium, phosphorus and vitamin B12.
Besides the foods already listed, you can also eat sardines, prunes, iodized salt, squid, crab, fish, scallops, tuna, cod, turkey breast, bananas, strawberries, and canned corn. For expert advice,.

Lima Beans or Sem Phali
People who are vegan or vegetarian and want to find the best source of iodine should try lima beans or sem phali. The amount of iodine can vary depending on the variation of iodine in irrigation water, soil, and fertilisers. While this is true, a cup of cooked lima beans usually contains around 2016 mcg (micrograms) of iodine, which is 10% of the daily recommended amount. Also, lima beans are high in magnesium, folate and fibre, making them good for your cardiac health.
