The epigenetic profiles at some loci depend on the parents’ nutritional states and to some extent also on nutritional factors after birth and later in life. This influence of nutritional factors on heritable epigenetic profiles is a rare instance where dietary exposure changes inherited traits. There is now good evidence that both starvation and overfeeding during pregnancy influence the likelihood of chronic disease later in life.
İt is not only the mother’s lifestyle that influences obesity risk and other outcomes in the offspring. Overeating changes the epigenetic profile of germline DNA of men, and some of these modifications appear to be transmitted to the children and by them in turn to later generations.
