==The benefits of Selenium are==
This mineral helps the body manufacture [[glutathione]], an enzyme required for proper detoxification of the body. Because toxic build-up in the body is linked to cancer, assisting your body with its natural, ongoing detoxification processes helps lessen your risk of cancer. In research, low dietary levels of selenium have been correlated with higher cancer incidence. Supplementation with selenium is a valuable cancer prevention tool.
*Nuts (Brazil Nuts) : Nuts, especially Brazil nuts, are a great source of selenium. Brazil nuts, which are also rich in [[magnesium]], provide the most selenium with 1917μg (2739% RDA) per 100 gram serving, 2550μg (3642% RDA) per cup, and 96μg (137% RDA) in a single kernel or nut. Mixed nuts by contrast provide about half as much selenium with 422μg (77% RDA) per 100 gram serving, 607μg (111% RDA) per cup, and 118μg (169% RDA) per ounce.
*Shellfish (Oysters, Mussels, Whelk): In addition to selenium oysters and shellfish are also a great source of iron, zinc, copper, and vitamin B12. Pacific oysters provide the most selenium with 154μg (220% RDA) per 100 gram serving, or 131μg (52% RDA) per ounce, and 38.5μg (55% RDA) per oyster. Other shellfish high in selenium include blue mussels and whelk which provide 90μg (128% RDA) of selenium per 100 gram serving, 76μg (109% RDA) per 3 ounce serving.
*Liver : The liver of most any animal is packed with nutrients like selenium. Often appearing on the culinary scene as pâté, liver can also be eaten in sausage (liverwurst), and prepared steamed or fried with onions and herbs. Lamb liver provides the most selenium with 116μg per 100g serving or 166% of the RDA. That is 99μg (141% RDA) of selenium in a 3 ounce serving.
