Periconceptional maternal dietary patterns contribute to embryonic growth and development. No knowledge is available about the impact of periconceptional maternal ultra-processed food consumption on embryonic growth. Therefore, the aim of the present study is to investigate the impact of periconceptional maternal ultra-processed food consumption on embryonic growth using repeated crown-rump length (CRL) and embryonic volume (EV) measurements.

… Reduced embryonic growth during the first trimester is associated with adverse birth outcomes, such as an increased risk of preterm birth, low birth weight, and small for gestational age. Neonates born with these conditions often show catch up growth, which is associated with increased risks of obesity and early features of non-communicable diseases in early life.

… Interventions promoting healthy food practices during pregnancy could be beneficial for embryonic growth.
