Abstract

The aim of this pilot study was to link habitual red meat consumption and protein intake to previously established urinary biomarkers, in a group of pregnant woman. Conventional chemical analyses and metabolomics were employed to assess the maternal urine fingerprint. The % of energy derived from meat intake was correlated with urea and creatinine levels, protein intake (g) with alanine and urea concentrations, while animal protein (g) with alanine levels. Maternal pre- pregnancy BMI was associated with alanine levels. There is a link between maternal dietary intake and urinary biomarkers.
