Dietary Impact On Gene Expression

Dietary impact on gene expression studies how nutrients and diet can influence which genes are turned on or off in the body. This field is closely linked to epigenetics, where external factors like diet modify gene activity without changing the underlying DNA sequence. Nutrients such as folate, B vitamins, and omega-3 fatty acids play a crucial role in this process. For instance, methylation, a common epigenetic mechanism, can be influenced by dietary folate, affecting gene expression related to cellular growth and cancer risk. Understanding how diet modulates gene expression helps researchers develop targeted nutritional strategies for preventing diseases like cancer, cardiovascular disorders, and metabolic syndromes.
