What can deficiency look like?
- Deficiency is uncommon in well-nourished populations

FOOD FIRST
Food sources
A varied diet is the first place to look for nutrients. Availability and nutrient content can vary by food, preparation and country.
Brazil nuts
Tuna, sardines and other seafood
Meat and poultry
Eggs
Whole grains and cereals
Food-source note: The selenium content of plant foods depends strongly on the soil in which they were grown.
Absorption & practical context
Dietary selenium is generally well absorbed, although chemical form influences metabolism and retention.
