Effect of a maternal high-fat diet with vegetable substitution on fetal brain transcriptome.

Maternal dietary conditions play a major role in fetal growth and brain development. The primary aim of this study was to determine the effects of 5% of energy substitution by vegetables in a maternal dietary fat on placental and fetal weight and on fetal brain gene expression. Two-month-old female C57BL/6 mice were fed 16% (normal-fat, NF), 45% fat (HF), or HF substituted with vegetables (5% energy, HF+VS) diets for 12 weeks.
