A nutritional analysis of food provided to Royal Naval personnel at sea.

The aim of this study was to determine the nutritional content of the foods provided to, and the confectionary purchased by, personnel serving at sea in British warships. Data were collected from the stores accounts of six ships over a period of 32,354 man-victualling-days. Analysis was carried out at the Nuffield Laboratories of Comparative Medicine. The food from the ships' gallies provided mean daily intakes of 3750 kcal, of which 42 per cent were derived from fats (17 per cent from saturated fats) and 9 per cent from added sugars. In taking account of confectionary purchased from NAAFI sources the total energy intake was raised to 4200 kcal of which 40 per cent were derived from fats (15 per cent saturated fats) and 12 per cent from added sugars. The results do not compare favourably with the recommendations of the reports of expert committees.
