Food Sources

Dietary intakes depend on the content of the soil where plants are grown or where animals are raised. Good sources of selenium include organ meats and seafood.Because plants do not require selenium, concentrations of this antioxidant in plants vary greatly, and food tables that list average selenium content are unreliable for plant foods. In the United States and Canada, the food distribution system ensures that regions with low selenium concentrations in the soil do not have low selenium dietary intakes [6].
