摘要

Blanket health messages to lower red meat intakes are being communicated at present. These could have adverse implications on the micronutrient quality of women’s diets. The current paper evaluates the nutritional impact of lower red meat intakes on British women’s micronutrient intakes and status. A secondary analysis of the UK National Diet and Nutrition Survey was undertaken using data from years 2008/2009 to 2011/2012. This was comprised of dietary and blood analyte data from 1384 and 641 females aged 11 to 64 years. Females consuming less than 40 g total red meat daily were more likely to have micronutrient intakes below the Lower Reference Nutrient Intake (LRNI) for zinc, iron, vitamin B12 and potassium and have lower habitual vitamin D intakes than females consuming between 40 and 69 g daily. After adjusting data for energy intake, zinc (% below the LRNI) and vitamin D (μg/day) remained statistically significant (p < 0.001). No significant differences were observed for blood biomarkers. Females consuming diets lower in red meat, i.e., <40 g daily, appear to have reduced micronutrient intakes, especially in the case of zinc and vitamin D. This should be considered when giving blanket advice for whole populations to reduce red meat intakes.
