Hi there!

It’s time for me to talk about another nutrient that I think you need to know about.

It’s called selenium. Isn’t that a pretty name?


What is selenium?

Selenium is a trace mineral that has powerful antioxidant properties and may play a role in fighting cancer.

Why is selenium good for you?

  • Component of antioxidant enzymes
  • Helps with immune system functioning
  • Activates thyroid hormones

What are some selenium rich foods?

In general, the best sources of selenium are seafood, meats, cereals, and grains. However, the selenium content of food varies significantly based on the soil content where the plant was grown or the animal raised.

So with that in mind, let’s look at some food sources of selenium.

Food Micrograms (μg)
1 ounce Brazil nuts 543
4 ounces tuna (cooked) 53
4 ounces shrimp 43
1 cup crimini mushrooms 23
4 ounces turkey 36
RDA* for adults 55
UL** for adults 400

*RDA is the amount of a nutrient that meets the needs of most people of a specified age and sex. This is a good amount to aim for.
**UL is the maximum daily intake level that is unlikely to cause negative health effects for most people of a specified age and sex. Keep your intake below this level.

What’s your favorite way to get selenium?

  1. I love me some seafood. But I also love mushrooms and nuts. 🙂

  2. Yes I enjoy selenium foods too, it improves our mental outlook, making us happier.

    Please remember to warn others however that Selenium is actually toxic in large doses! You know the human mentality – “if some is good then more is better” and in this case it isn’t. Thanks,
