At 537 µg of selenium per 28 grams and 2,550 µg per 1 cup, Brazil nuts are the top food with the highest amount of this nutrient (4).
If you can’t find these nuts, don’t fret; just turn to other easy-to-find selenium sources such as tuna, sardines, and shrimp. These kinds of seafood are also good sources of omega-3 fatty acids, which can support weight loss. (31)
Organ meats such as liver and more common meats such as chicken, beef, pork, and turkey are also excellent sources of selenium.
