title: Bioavailability of selenium in mushrooms, Boletus edulis, to young women.
abstract: The bioavailability of selenium (Se) in mushrooms, Boletus edulis, to young Finnish women was studied by giving them 150 micrograms Se as mushrooms for 4 weeks. The indicators of body selenium status were plasma and erythrocyte Se levels and plasma and platelet glutathione peroxidase (GSH-Px) activity. The Se level in erythrocytes increased significantly (26%), while only slight enhancement were found in plasma Se and plasma or platelet GSH-Px activity. The results indicate that the metabolism of mushroom-Se is different from that of wheat-Se or sodium selenate. However, by the criteria of plasma Se level or plasma and platelet GSH-Px activity the bioavailability of mushroom-Se is reasonably low.
