The Claim
Ultra-processed food intake during pregnancy is not significantly associated with infant weight-for-length trajectories from birth to 1 year of age.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating ultra-processed foods during pregnancy does not change how infants grow in weight relative to their length during the first year of life.
See the scientific wording
Ultra-processed food intake during pregnancy is not significantly associated with infant weight-for-length trajectories from birth to 1 year of age, despite associations with maternal weight gain and inflammation, suggesting that infant growth may be influenced by different or additional factors.
When a pregnant person eats a lot of ultra-processed food, their body stores more fat and has more inflammation, but these changes do not change how the baby uses nutrients to grow in length and weight during the first year. The baby’s growth follows its own pattern, guided by genes and placental signals that are not affected by the mother’s diet-related changes.
What the research says
1 studyEven though moms who ate more ultra-processed foods gained more weight and had more inflammation, their babies didn’t grow faster or slower in weight compared to their length during the first year. So, what the mom ate didn’t seem to affect how the baby grew.
