Poor-quality prenatal dietary patterns are related to the mental health of mothers and children - could dietary improvement break the cycle?

[Extract] Poor-quality prenatal diets are related to antenatal depressive symptoms and stress in women.1 Likewise, prenatal depressive symptoms and unhealthy diets are both independently associated with higher levels of child emotional-behavioral dysregulation. Addressing diet may influence multiple interconnected pathways that are relevant to the pathogenesis of mental disorder, such as gut microbiota, inflammatory status, the hypothalamic-pituitary-adrenal axis, oxidative stress, and brain-derived neurotrophic factors. This raises the question: can dietary improvement in pregnancy prevent mental disorders in mothers and help prevent the intergenerational transmission of mental ill-health to children? If so, what dietary advice should be followed, and would this advice change based on the disorder?
