Food is a part of our everyday lives, but not many people know that certain foods can change their epigenetics. Epigenetics is the study of heritable changes in gene function that occur without alterations to the DNA sequence; it regulates gene expression and determines the functional and structural development of cells, tissues, and organs. There are many factors that come into play with individuals' health, however, it all begins with pre-natal and postnatal nutrition that set out the blueprint to one's epigenetics and there are studies that prove so. Researches have conducted surveys and longitudinal studies on pregnant women and the health of their children. Agouti mice are huge part of analyzing how certain diets can effect our health and essentially find a solution for reversing diseases in future generations.
