ABSTRACT
Dietary balance is among the major requirement to maintain the health of an individual. Many researchers have taken efforts to understand the impact of macro as well as micronutrients on the physiology of humans with the aim to avoid nutrients both in excess and shortage. However, conventional tools were not enough to maintain long-term health and wellbeing. Moreover, it also fails to consider that from person to person, the need of nutrition may vary which may also be genetic factor-dependent. There was a need of some novel tool that can focus on an individual need of nutrients. “Nutrigenetics and Nutrigenomics” is the recently developed tool that plays a key role in the study of how human genetic variation is responsible for different nutritional demands from every human being. This chapter provides overlook of the significance of Nutrigenetics and associated tools.
