It is hard to consider<unk>  extremely preventable because the only way to ensure that the individual is getting enough selenium would be to test the soil in the area. However, one way that selenium intake can be improved is to increase intake of foods that are rich with selenium. Examples include Brazil nuts, onions, canned tuna, beef, cod, turkey, chicken breast, enriched pasta, egg, cottage cheese, oatmeal, white or brown rice, and garlic. If the individual lives in an area that does not have selenium enriched soil, dietary supplementation should be considered. To determine whether or not an individual is selenium deficient, blood testing is performed.
