Age and gender variation in food energy and nutrient intakes, 1974-1998

The National Food Survey (NFS) is unique in providing a long continuous record of British household food acquisitions for home supplies and it is frequently used to give an overview of changes in British diet, see [1] for a recent example. In contrast the National Diet and Nutrition Survey (NDNS) programme provides detailed crosssectional information on the diets of groups of the population at widely spaced intervals of time.
