Maternal diets high in UPFs may influence children’s health years later

A narrative review of 84 publications links higher ultra-processed food intake during pregnancy and early childhood with poorer diet quality, maternal complications, childhood obesity, and potential immune, metabolic, and neurodevelopmental effects. The authors identify possible microbiome and biopsychosocial pathways but emphasize that the predominantly observational evidence cannot establish causality.
