Selenium is an essential nutrient that plays a vital role in many bodily functions. It is an antioxidant that protects cells from damage, regulates thyroid function, and supports the immune system.
In this article, we will discuss the benefits of selenium and the top food sources that you can add to your diet to ensure you are meeting your body’s needs.
The Benefits of Selenium
Selenium has many health benefits, including:.
1. Antioxidant Properties
Selenium is an antioxidant that helps protect cells from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to aging and chronic diseases such as cancer, heart disease, and diabetes.
Selenium helps neutralize these free radicals and protects cells from damage.
2. Regulates Thyroid Function
The thyroid gland produces hormones that regulate metabolism and other bodily functions. Selenium plays a role in the production and metabolism of thyroid hormones and helps protect the thyroid gland from damage.
A deficiency in selenium can lead to thyroid problems, such as hypothyroidism.
3. Supports the Immune System
Selenium is essential for the proper functioning of the immune system. It helps activate immune cells and enhances the body’s ability to fight off infections and diseases.
A deficiency in selenium can weaken the immune system and increase the risk of infections.
4. May Reduce the Risk of Certain Cancers
Selenium has been shown to have cancer-fighting properties. It can help prevent DNA damage and cell mutations that can lead to cancer.
Studies have shown that selenium supplementation may reduce the risk of certain types of cancer, including prostate, lung, and colorectal cancer.

The recommended daily intake of selenium for adults is 55 micrograms per day. Here are some of the top food sources of selenium:.
1. Brazil Nuts
Brazil nuts are one of the best sources of selenium. Just one ounce (6-8 nuts) provides more than 700% of the daily recommended intake of selenium.
However, it is important to note that Brazil nuts are high in calories and should be consumed in moderation.

Meat and poultry are good sources of selenium. One serving of beef, chicken, or turkey provides about 20-30% of the daily recommended intake of selenium. Other animal sources of selenium include pork and lamb.
4. Eggs
Eggs are a good source of selenium, with one large egg providing about 10% of the daily recommended intake of selenium.
However, it is important to note that most of the selenium in eggs is found in the yolk, so it is best to consume the whole egg to get the full benefits.
5. Grains
Grains such as rice, wheat, and oats are also good sources of selenium. One serving of cooked rice or pasta provides about 10-15% of the daily recommended intake of selenium.
In Conclusion
