Nutrigenomics is a branch of the genetics science field. It deals with the effects that food and its ingredients has on the gene expression. This means that Nutrigenomics is a research field that focuses on identifying and understanding the interaction between foods and nutrients and the genome on the molecular level.
Additionally, this field of science tests the effects of genetics on the reception and absorption of different food types and their ingredients by adjusting the gene expression to specifics of absorption, metabolism, as well as biological and environmental effects. By doing so, Nutrigenomics will develop a rational tool to create an efficient diet based on the human genome.
By understanding the mechanism of nutritious substances or the influences dietary policies, Nutrigenomics attempts to define the causality or the relation between specific foods, specific dietary programs (diets) and the human health.
Ultimately, personal nutrition consultation will become a huge contribution to public health in the next decade. This science is expected become a main concept in the field of nutrition; delivering the information and conducting the tests will become easy and convenient for the wide public.
