Findings from the latest National Diet and Nutrition Survey

Abstract

The National Diet and Nutrition Survey (NDNS) of adults aged 19-64 years, carried out in 2000-1, is part of the NDNS programme, a series of cross-sectional surveys aiming to provide detailed quantitative information on the diet, nutritional status and related characteristics of the British population. The programme is split into four surveys of different population age-groups, conducted at approximately three-yearly intervals. In the survey of adults food consumption data were collected from 1724 respondents using a 7 d weighed-intake dietary record. Other components included: height, weight, waist and hip circumference and blood pressure measurements; a 24 h urine sample; a blood sample; a record of physical activity. Results have been published in four volumes covering food consumption, energy and macronutrient intakes, micronutrient intakes and nutritional status, including physical measurements and physical activity. The results have shown that, based on a comparison of nutrient intakes with the UK dietary reference values, adults in Britain are generally getting sufficient nutrients from their diets. However, younger adults (particularly women) and those in lower socio-economic groups are more likely to have low micronutrient intakes and lower levels of some nutritional status indices. The proportion of food energy derived from total fat has fallen since the last survey of this age-group in 1986-7 and is close to the dietary reference value, while the proportion of energy derived from saturated fatty acids and non-milk extrinsic sugars exceeds the dietary reference values. The prevalence of overweight and obesity has increased since 1986-7 and physical activity levels are low.
