In 2014, the combined results from the Years 1, 2, 3 and 4 of the National Diet Nutrition Survey (NDNS) 2008/09 – 2011/12 were published. The NDNS rolling program aims to provide quantitative data on the food and nutrient intakes, sources of nutrients and nutritional status. The program is carried out in all four countries of the United Kingdom (UK) and is designed to be representative of the UK population. A random sample of 21,573 addresses from 799 postcode sectors was issued. Where there were multiple households at an address, a single household was selected at random. For each household, either one adult (aged 19 years and over) and one child (aged 1.5 to 18 years), or one child only were randomly selected to take part. The response rate for completion of the diary of food and drink consumption over four consecutive days was 56% for Years 1 to 4 combined.
- Adults aged 19 to 64 years on average consumed 4.1 portions of fruit and vegetables per day, while adults aged 65 years and over consumed 4.6 portions per day. Only 30% of adults and 41% of older adults met the “5-a-day” recommendation.
- Mean consumption of fruit and vegetables for children aged 11 to 18 years was only 3.0 portions per day for boys and 2.7 portions per day for girls. Only 10% of boys and 7% of girls in this age group met the “5-a-day” recommendation.
- The mean consumption of oily fish in all age groups was well below the recommended one portion (140g) per week. For example, mean consumption in adults aged 19 to 64 years was 54g per week (52g for men and 54g for women) and for adults aged 65 years and over mean consumption was 90g per week (103g for men and 81g for women).
- Intakes below the Lower Reference Nutrient Intake (LRNI) were found in a proportion of the 11 to 18 years age group for vitamin A, riboflavin and folate (girls only). Women aged 19 to 64 years also had intakes below the LRNI for riboflavin.
- There was evidence of an increased risk of vitamin D deficiency in all age/sex groups. Year-round, the proportion of children with a serum 25-OHD concentration below 25nmol/L ranged from 7.5% for children aged 1.5 to 3 years to 24.4% for girls aged 11 to 18 years and for adults this ranged from 16.9% for men aged 65 years and over to 24.1% for women aged 65 years and over. The proportion of participants with a serum 25-OHD concentration below 25nmol/L was higher in the winter months.
- For iron, both the dietary intake and biochemical status data indicated an increased risk of iron deficiency in girls aged 11 to 18 years and women aged 19 to 64 years.
- There was evidence of intakes below the LRNI in a substantial proportion of older children and adults for some minerals, particularly magnesium, potassium and selenium.
