What the research found
Study (observational cohort). Zacher, Vogel and Leipzig colleagues report in the European Journal of Clinical Nutrition (doi 10.1038/s41430-026-01817-z) on 1,404 pregnant women in Germany’s LIFE Child cohort (2011–2025; 1,196 newborns). Hierarchical clustering found four patterns: mixed, traditional bread-based, high ultra-processed, and vegetable-rich. The high-UPF cluster was younger, with lower socioeconomic status, higher pre-pregnancy BMI, and higher gestational weight gain; the vegetable-rich cluster was older, with lower BMI. Infant birth-weight and SGA/LGA differences were mostly non-significant; vegetable-rich infants had slightly higher gestational-age-adjusted length. Single diet recall; German cohort. Educational nutrition notes, not a pregnancy diet prescription.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
