Nutrigenetics intends to recognize how genetic variation affects response to nutrients. This data can be applied to improve health and prevent or treat diseases. The ultimate aim of nutrigenetics is to offer individuals customized nourishment in light based on their genetic makeup.

A major goal for nutrigenetic scientists is to identify genes that make certain people more susceptible to obesity and obesity related diseases. The thrifty gene hypothesis is a example of a nutrigenetic factor in obesity. Future progressions in nutrigenetics research may conceivably demonstrate the presence of thrifty genes and in addition discover counter-impacts keeping in mind the end goal to prevent obesity and obesity-related diseases.

Main goal in nutrigenetics is to allow nutritionists and doctors to individualize health and diet suggestions. Therefore, preventive medicine, diagnostics and therapies could be optimized.
