Future developments in the UK food composition tables

In man, one of the classical ways of assessing nutritional adequacy is by means of dietary surveys. Such surveys nevertheless have a number of limitations, including: (1) the groups available for study may not be ideal for the purpose, (2) even if a full 7 d weighed survey is done, the diet may not be properly recorded or it may have been altered by participation in the survey, (3) the nutritional value of the diet may be incorrectly assessed if inappropriate food composition tables are used, and (4) the yardsticks for assessing the results (e.g. recommended dietary allowances, heights and weights or biochemical indices) may be of limited relevance or too insensitive to be useful. The present paper addresses the third of these limitations. As the Ministry of Agriculture, Fisheries and Food (MAFF) has long used food composition tables for assessing its own policies and surveys, and is now expanding and updating the standard tables in this country (Paul & Southgate, 1978), we would like to describe the MAFF’s involvement in this work in some detail before outlining future developments.
