Abstract

A good diet during pregnancy is essential for the well-being of the mother and the development of a healthy baby. There is evidence that long-term problems for the baby may arise when the mother’s nourishment is less than ideal. Epigenetic processes are proposed as a key mechanism by which maternal nutrition influences offspring’s life-long health. In this chapter, we consider the evidence supporting this hypothesis. We review the literature describing the effects of extreme under-nutrition in pregnancy on the offspring, through studies of the long-term effects of unexpected famine. We consider the effects of over-nutrition in pregnancy, addressing the long-term outcomes of maternal obesity and diabetes during pregnancy on the offspring. We describe the evidence for the involvement of epigenetic mechanisms, particularly DNA methylation, as mediators of these effects. Finally, we suggest that paternal nutrition may also affect offspring outcomes through epigenetic changes in sperm and that these may affect the health of subsequent generations through the paternal lineage.
