Genetics, Nutrition, and Health: A New Frontier in Disease Prevention.

Genetic differences among individuals affect the metabolism, gene regulation, and sensitivity of disease in response to diet therefore traditional nutrition research expands to integrate the influence of genetics on the dietary response of an individual.Nutritional genomics which includes the reciprocal and complementary field of nutrigenetics and nutrigenomics, studies the interactions between gene and dietary components.Nutrigenetics studies the genetic effect on the metabolism of nutrients while Nutrigenomics explores the impact of nutrients on genetic expression thus shaping personalized dietary requirements.A personalized dietary approach based on comprehensive genomic profiling (genomics, proteomics, metabolomics, transcriptomics) can help to promote health and prevent illness.
