What are the health benefits of selenium?

Howard S. Smith

Selenium is a trace mineral that may hold the key to staying disease-free as it helps to keep the immune system working optimally and is important for a healthy thyroid gland. Selenium is an important part of the antioxidant enzyme as it helps to fight free radicals that cause damage to healthy tissue. There are some studies on rheumatoid arthritis patients, indicating that they have reduced selenium levels in their blood. This may be because these people have a low intake of selenium through foods. Current findings are preliminary and no recommendations for selenium supplements are available. The Recommended Daily Intake (RDI) is 70 micrograms. The best food sources are Brazil nuts, beef, tuna, turkey, chicken, walnuts, cheese, eggs, cottage cheese, and enriched grain products. One three and one-half ounce serving of tuna gives you a full day’s requirement of selenium.
