Fresh Versus Tinned Tuna

The Importance of Selenium

Selenium is an essential mineral that plays a crucial role in our bodies. It helps boost our immune system, maintains a healthy thyroid function, and protects our cells from damage. One of the best sources of selenium is seafood, particularly tuna.

The Amount of Selenium in Tuna

Tuna contains varying amounts of selenium, depending on the type of tuna and where it was caught. On average, fresh tuna contains approximately 70 micrograms of selenium per 100 grams. Canned tuna, on the other hand, contains slightly less, with an average of 45 micrograms per 100 grams.

Why Selenium Levels Vary

The selenium content in tuna can vary depending on several factors. For instance, tuna caught in certain areas may have higher levels of selenium due to the selenium-rich environment. Also, the age and size of the tuna can also impact the selenium content.

The Health Benefits of Selenium in Tuna

Selenium plays a vital role in maintaining good health, and consuming tuna is an excellent way to ensure you get enough of this essential mineral. Selenium can help reduce the risk of heart disease, boost your immune system, and improve thyroid function.

The Risks of Consuming Too Much Selenium

While selenium is essential for good health, consuming too much of it can be harmful. The recommended daily intake of selenium is 55 micrograms per day for adults. Consuming too much selenium can lead to selenosis, which can cause symptoms such as hair loss, skin rash, and nausea.

The Best Ways to Consume Tuna

Tuna is a versatile fish that can be consumed in several ways. You can enjoy it grilled, baked, or raw as sushi or sashimi. Canned tuna is also a convenient option for quick and easy meals. However, it’s essential to choose high-quality, sustainably caught tuna to ensure you get the most nutritional benefits.

The Bottom Line

Tuna is an excellent source of selenium, which is essential for good health. Consuming tuna in moderation as part of a balanced diet can help boost your immune system, improve thyroid function, and reduce the risk of heart disease. However, it’s crucial to be mindful of the risks of consuming too much selenium and choose high-quality, sustainably caught tuna.
