Ministry of Agriculture, Fisheries and Food iii Preface The National Food Survey has now been in existence for thirty years. Through out that period it has been an unrivalled source of information on household food expenditure and consumption as recorded by many thousands of house wives. The Committee is most grateful to them. From time to time it is suggested that the survey has outlived its purpose and should be brought to an end. We have, however, found no evidence that there is any lessening of interest in how different sections of the public are fed, or in the cost of food, or in standards of nutrition. Moreover, there is a considerable demand from the food trades, nutritionists and university research workers for information obtained from the survey. The Committee nevertheless is conscious of the need to review and improve wherever possible the conduct of the survey and the analysis of its results. Significant changes have therefore been introduced during the lifetime of the survey and the Committee has summarized in its reports the results of a number of special studies. In the present report there are the customary analyses and tabulations of Survey data according to income group, type of family, region and degree of urbanization. In addition the report gives the results of a study of the influence of the age of the housewife on household food expenditure, consumption and nutrition and, also, of the extent to which the influence of age is affected by the socio-economic grouping of the household as determined by the occupation of the head of the household. An appendix to the report presents a special analysis of garden, allotment and other supplies of food for which no direct payment was made and shows how these have declined over the past ten years. Another appendix presents data on household consumption of beverages and the extent to which they are sweetened with sugar or with other sweeteners. Some data on the growth in ownership of refrigerators in the different regions and types of family are also given. The nutritional section of the report contains estimates of the average energy value and nutrient content of the diet in various types of household. These estimates are compared with the new intakes recommended by the Department of Health and Social Security: for this purpose intakes of vitamins A & D are now expressed in units of weight and those of nicotinic acid are expressed as nicotinic acid equivalents which include the contribution from tryptophan. Estimates are also given of the concentration of nutrients in relationship to the energy value of average diets of various groups of households. Estimates of expenditure and consumption for the main food groups continue to be published in summary form as soon as they become available in the Monthly Digest of Statistics for all households, income groups and types of family. Estimates of consumption for all households are also published each quarter in the Board of Trade Journal, together with some nutritional data. Applications for unpublished analyses should be addressed to the National Food Survey Branch of the Ministry of Agriculture, Fisheries and Food, Tolcarne Drive, Pinner, Middlesex HA5 2DT. v Preface The Committee again wishes to record its appreciation of the work of the Secretaries and their staffs and also to thank Miss Hollingsworth for her part in preparing the sections on nutrition in the absence abroad of Dr. Greaves. The Committee also records its indebtedness to the officers of the Government Social Survey, and to the British Market Research Bureau for undertaking the fieldwork and coding of the Survey. As this Report goes to press, the Committee has learned with great regret of the death of Sir Norman Wright, C.B., M.A., D.Sc, Ph.D., LL.D., F.R.I.C., F.R.S.E., its first Chairman, to whose wise guidance from 1948 to 1959 the National Food Survey and all who make use of it owe so much.
