It is evident that a multitude of lifestyle factors exert a considerable influence on the wellbeing of pregnant women and their foetuses. Of these factors, dietary behaviour is of particular significance. Despite the increased requirements for certain nutrients, such as iron and folic acid, during pregnancy, the fundamental principles of healthy eating remain consistent with those of the general population. A substantial body of research has established that an inadequate nutritional intake during pregnancy exerts a detrimental effect on perinatal outcomes, including complications during childbirth and suboptimal foetal development. Furthermore, this inadequate intake poses risks to the long-term health of the offspring. It is imperative to ensure an adequate intake of energy, protein, vitamins, and minerals in order to satisfy the needs of both the mother and the foetus.

The developmental origin of health and disease (DOHaD) model hypothesises that the intrauterine environment can induce epigenetic modifications and alter gene expression patterns in the foetus. These alterations have the potential to render neonates and children susceptible to a range of diseases later in life. The formulation of national and international nutritional guidelines is meticulous, informed by robust evidence regarding the benefits of adequate nutrient consumption and the risks associated with deficiencies.
