Selenium and ageing

Selenium is a mineral that is vital for our brains, hearts, skin and bones and if we don’t get enough of this essential substance we might be up for cognitive decline, weakened muscles and premature skin ageing.  Selenium-rich foods include Brazil nuts, seven of these a day, and then a whole range of animal-based items such as tuna, sardines, oysters, salmon, ham, turkey, pork and eggs.  For those of us steering clear of these options supplementing with some extra selenium, not more than five drops a day of the liquid form of this mineral, would suffice.
