Dietary intakes of selenium in the UK during the 70s were nearly twice the level we consume today! Moreover, official figures from MAFF show that the selenium intake for 80% of adults in the UK is now below the recommended daily intake. This situation is due in part to the reduction in imports of selenium-rich, high protein wheat used for bread making from North America, coupled with the wide usage of selenium-antagonistic artificial fertilisers & acid rain exposure. As a vital component of the bodys antioxidant defence system, a key player in thyroxine metabolism as well as an invaluable nutrient in reproductive health, falling dietary intakes are a real cause for concern.
