title: Some consequences of the new UK 'recommended daily amounts of food energy and nutrients' for evaluating food consumption surveys.
abstract: The amounts of energy and nutrients which have been recommended by the Department of Health and Social Security in 1969 and 1979 are compared. For the nation as a whole, the recommendations for energy and protein have decreased by 6 per cent; thus, the adequacy of an otherwise unchanged diet will appear 6 per cent higher than before. The changes for iron, calcium and the three main B-vitamins are smaller, while vitamin C and vitamin A are virtually unaffected. Nevertheless, as the method of calculating retinol equivalents in the diet should now conform to worldwide practice, the amount of vitamin A in the average diet will appear to be about 6 per cent less than before. It will be no longer practical to evaluate dietary intakes of vitamin D, but there are now official recommendations for folic acid.
