In many animal species, the mother's diet and the environment in which she lives affect the health of her future offspring, as well as subsequent generations. To a large extent, this is done through the so-called epigenetic inheritance. Environmental factors do not change the nucleic acid sequence in parents' cells, but they can modify the level of gene expression, for example by changing their methylation. As the latest research results say, information on the mother's state of health and nutrition can also be passed onto offspring directly - through fats, proteins and various metabolites. Scientists are still conducting research related to the impact of nutrients in food consumed by mothers on the development of the nervous system in future generations.
