Interesterified fat or palm oil as substitutes for partially hydrogenated fat in maternal diet can predispose obesity in adult male offspring.

Background & Aims: Palm oil (PO) and interesterified fat (IF) have been used to replace partially hydrogenated fat (PHF), which is rich in trans isomers, in processed foods. The purpose of this study was to investigate whether normolipidic diets containing PHF, IF, or PO consumed during pregnancy and lactation affect total body adiposity and adipose tissue morphology of adult offspring mice.

Methods: Four groups of female C57BL/6 mice were fed, during pregnancy and lactation, a control diet (control group, CG), a PHF diet (trans group, TG), a PO diet (PG group), or an IF diet (IG group).

Effects of protein restriction during gestation and lactation on cell proliferation in the hippocampus and subventricular zone: functional implications. Protein restriction alters hippocampal/SVZ cell proliferation.

There is no consensus about the effects of protein restriction on neurogenesis and behavior. Here, for the first time, we evaluated the effects of protein restriction during gestation and lactation, on the two major neurogenic regions of the adult brain, the subgranular zone (SGZ) of the hippocampal dentate gyrus and the subventricular zone (SVZ), simultaneously. We also assessed different types of behavior relevant to each region.
