Epigenetics Crosslink with Nutrition and Brain Function

Epigenetics is changing the gene expression without any modifications in the nucleic acid. Aging is a normal biological process, and it is associated with epigenetics. Previous studies have linked neuroepigenetics with nutritional epigenetics in studying epigenetics of the brain. This chapter introduced and explained epigenetics, including DNA methylation, its effect on the brain, how epigenetics affects brain function, and the relationship with nutrition and metabolism, including new technologies, challenges, and limits.
