The intersection of psychology and biology is a subject of much research and debate. By understanding the role that these two subjects play in one another, we can gain a better comprehension of the human body and mind. One area of significant exploration is that of epigenetics: the study of how environmental factors can alter gene expression and behavior. This field has advanced our understanding of how experience has an influence on our genes and our behavior, and has been fundamental in developing new treatments for a range of physical and mental conditions.
Epigenetics works by changing the structure of our DNA—not its sequence—to affect gene expression. This can be expressed through the addition or alteration of base pairs or methylation, the binding of proteins onto DNA strands. As a result, certain genes may become turned “on” or “off,” leading to changes in behavior, development or health. For instance, research has found that prenatal nutrition can affect obesity and cardiovascular disease risk in adulthood, suggesting that environmental factors
