Objective: To examine dietary selenium intake and indices of selenium status (plasma and red blood cell selenium and glutathione peroxidase activities) in apparently healthy Scottish individuals.
Design and subjects: One hundred subjects, aged between 40 and 60 y, completed a seven day weighed food; intake and provided blood samples for selenium status analysis.
Setting: Inverurie, Aberdeenshire, Scotland,
Results: Average reported selenium intake was low (43 mu g/d). A significant number of subjects had reported intakes below the RNI. Low levels of plasma selenium were also found but no subject had values below 40 mu g/l. Red blood cell selenium was within the reference range established for a healthy UK population. Smoking status had no consistent effect on selenium status.
Conclusions: The results of the present study suggest that selenium status of certain Scottish individuals may be compromised and that further studies are warranted.
