INTRODUCTION
During pregnancy, essential immunometabolic adaptations occur to sustain pregnancy and promote foetal growth and development (Kalagiri et al., Maternal dietary intake is one potentially modifiable behaviour that might positively impact materno‐foetal immunometabolic markers (Martin et al., Further studies considering not only dietary habits but also diet quality during pregnancy, and their relation with both maternal and foetal immunometabolic serum markers, are required to provide more robust evidence on this relevant topic. Therefore, the aim of the present study was to analyze the associations of MD adherence during pregnancy and MD components, with maternal and cord arterial and venous glycemic, lipid and inflammatory serum markers.
