What is the study called that examines how food choices can alter genetic expression?

Nutrigenomics is the study that focuses on how food choices and dietary factors can influence gene activity and expression. This field combines aspects of nutrition and genomics, investigating how different nutrients can affect the body's genetic makeup and the way genes are expressed.

By understanding the relationship between diet and genetics, nutrigenomics aims to optimize health and wellbeing through personalized nutrition, addressing how specific dietary components can promote or inhibit various biochemical processes within the body at a genetic level.

In contrast, psychogenetics primarily concerns the influence of genetics on behavior and psychological traits, while epigenetics focuses on changes in gene expression that do not involve alterations to the underlying DNA sequence. Genetic profiling involves analyzing an individual's DNA to identify specific genetic characteristics but does not directly address the interaction between diet and genetic expression.
