Selenium is a nutrient that’s needed in tiny amounts. Nevertheless, it’s vital we get enough for good health. Unfortunately, figures from the National Diet and Nutrition Survey reveal that nine percent of 4-10 year olds, 17 percent of 11-18 year olds, 38 percent of 19-64 year olds and 42 percent of over 65’s have very low intakes of this nutrient. This nutrient plays a role in maintaining normal hair and nails. It supports the immune system to work normally and is needed for normal thyroid function and spermatogenesis. It also plays a role in protecting cells from oxidative damage. Most fish – white, oily and shellfish – are rich in selenium so can make a significant contribution to our intakes of this nutrient.
