Micronutrient intakes of British adults across mid-life: a secondary analysis of the UK National Diet and Nutrition Survey

Summary

This paper presents a secondary analysis of the UK National Diet and Nutrition Survey to characterise micronutrient intakes among British adults across mid-life. It likely identifies specific nutrients — potentially including magnesium, selenium, iodine, vitamin D, and folate — where a meaningful proportion of adults fail to meet recommended intakes. The findings contribute to the evidence base on nutritional inadequacy in the UK adult population and may have implications for dietary guidance and public health policy.

UK applicability

The study is directly applicable to UK conditions, drawing exclusively on nationally representative UK dietary data and interpreting findings against UK dietary reference values established by the Scientific Advisory Committee on Nutrition (SACN).

Key measures

Micronutrient intake levels (mg/day or µg/day); proportion of adults below Lower Reference Nutrient Intake (LRNI) or Reference Nutrient Intake (RNI); dietary reference value comparisons by age group and sex

Outcomes reported

The study examined dietary micronutrient intakes among British adults aged approximately 19–64 years using secondary analysis of the UK National Diet and Nutrition Survey (NDNS), assessing the prevalence of inadequate intakes relative to dietary reference values. It likely reported proportions of the population falling below recommended nutrient intakes for key vitamins and minerals.
