selenium in salmon

Salmon is a popular fish that is consumed worldwide due to its delicious taste and numerous health benefits.

One of the essential minerals found in salmon is selenium.

Selenium is a trace element that plays a vital role in maintaining human health. It is a powerful antioxidant that helps to protect the body against oxidative stress and cell damage caused by free radicals.

Studies have shown that salmon is an excellent source of selenium.

Selenium in salmon is found in the form of selenoproteins, which are essential for the proper functioning of the body.

Selenium deficiency can lead to various health problems such as thyroid dysfunction, cardiovascular disease, and cancer.

Therefore, it is crucial to consume foods that are rich in selenium, such as salmon, to maintain optimal health.

In this article, we will discuss the importance of selenium in salmon and how it can benefit human health. We will also explore the recommended daily intake of selenium and the potential risks of consuming too much or too little selenium.

Whether you are a seafood lover or not, the information provided in this article will help you make informed decisions about your diet and overall health.

What is Selenium?

Selenium is a trace mineral that is essential for human health. It is found in soil, water, and some foods. Selenium is important for the proper functioning of the immune system, thyroid gland, and other organs in the body.

Recommended Daily Intake of Selenium

The recommended daily intake of selenium varies depending on age and gender.

According to the National Institutes of Health (NIH), the recommended daily intake of selenium for adults is 55 micrograms (mcg) per day. Pregnant and breastfeeding women require slightly more selenium, with recommended daily intakes of 60 and 70 mcg per day, respectively.

Consuming too much selenium can be harmful, so it is important to not exceed the tolerable upper intake level (UL) of 400 mcg per day for adults. High levels of selenium can cause selenosis, a condition that can lead to hair loss, brittle nails, and gastrointestinal upset.

It is possible to get enough selenium through a balanced diet that includes foods such as Brazil nuts, seafood, poultry, eggs, and whole grains.

However, some people may require selenium supplements if they are not getting enough through their diet. It is important to talk to a healthcare professional before taking any supplements, as too much selenium can be harmful.

Selenium in Salmon

Salmon is a popular and healthy food that is rich in various nutrients, including selenium. Selenium is an essential mineral that plays a crucial role in several bodily functions, such as metabolism, immune system function, and thyroid hormone production. In this section, we will discuss the benefits of selenium in salmon and the levels of selenium in different types of salmon.

Benefits of Selenium in Salmon

Selenium is a powerful antioxidant that helps protect cells from damage caused by free radicals. It also plays a crucial role in the body’s immune system, helping to fight off infections and diseases.

Additionally, selenium is essential for thyroid hormone production, which helps regulate metabolism and energy levels.

Research has shown that consuming selenium-rich foods like salmon may help reduce the risk of certain types of cancer, such as prostate, lung, and colorectal cancer. Selenium may also help improve heart health by reducing inflammation and oxidative stress.

Selenium Levels in Different Types of Salmon

The selenium content in salmon can vary depending on the type of salmon and its diet. Wild-caught salmon tends to have higher levels of selenium than farmed salmon, as wild salmon feed on a diet of nutrient-rich marine organisms.

Farmed salmon, on the other hand, are typically fed a diet of fishmeal and fish oil, which may not contain as much selenium.

According to a study published in the journal Aquaculture, the minimal selenium requirement for Atlantic salmon-fed plant-based feeds containing 0.24 ppm basal selenium level was found to be exceeded.

Another study found that the selenium content in different types of salmon ranged from 0.06 to 0.25 mg/kg. Chinook salmon had the highest levels of selenium, while sockeye salmon had the lowest.

Type of SalmonSelenium Content (mg/kg)

It is worth noting that the selenium content in salmon can also be affected by factors such as the salmon’s age, size, and geographic location. However, overall, salmon is a great source of selenium and can provide numerous health benefits when consumed as part of a balanced diet.

How to Cook Salmon to Retain Selenium

Salmon is a great source of selenium, which is an essential mineral that plays a vital role in many bodily functions. However, the way you cook salmon can impact the amount of selenium that remains in the fish. Here are some tips on how to cook salmon to retain selenium:

  • Cook salmon at a low temperature: High heat can cause selenium to break down and be lost. Cooking salmon at a lower temperature can help to retain more selenium.
  • Grill or bake salmon: Grilling or baking salmon is a great way to cook it while also retaining selenium. These methods help to lock in the nutrients and flavor.
  • Avoid frying salmon: Frying salmon can cause the selenium to be lost due to the high heat and oil used in the cooking process.
  • Season salmon with herbs and spices: Adding herbs and spices to salmon can not only enhance its flavor but also help to retain more selenium. Some herbs and spices that go well with salmon include dill, lemon, garlic, and black pepper.

By following these tips, you can ensure that you are getting the most out of your salmon in terms of selenium content. Remember to cook salmon at a low temperature, grill or bake it, avoid frying it, and season it with herbs and spices for maximum retention of selenium.


Research has shown that including a salmon fish protein supplement in the daily diet for 8 weeks can increase serum vitamin B12 and selenium concentrations. Selenium is an essential trace mineral that is needed in small amounts, and it comes from foods consumed. It is important to note that selenium toxicity can occur if consumed in excessive amounts.

Atlantic salmon and other fish species require selenium for proper growth and development. Changes in feed composition for Atlantic salmon may require additional selenium supplementation. Both selenium and vitamin E are necessary to prevent muscular dystrophy in Atlantic salmon and exudative diathesis in rainbow trout.

It is important to consider the potential risks and benefits of consuming salmon and other fish species in relation to selenium content. While selenium is essential for health, excessive intake can lead to toxicity. Consumption of fish species with high levels of selenium, such as swordfish and tuna, should be limited.
