Nutrigenomics is a science that studies the relationship between genetic factors and nutrients that have a specific composition and are capable of inducing gene expression in the body. The composition of nutritional needs based on genotype profiles will provide knowledge about what types of food are suitable for consumption. shows what types of food we need and what foods we should avoid, based on a database of genes associated with a disease. The food we eat is composed of chemical molecules that are capable of inducing gene expression. Nutrigenomics is the application of genomics in the development of new technologies, such as transcriptomics, proteomics, metabolomics and epigenomics based on the analysis of gene function and expression. This knowledge is important for maintaining health and preventing potential chronic diseases that may attack so that the need for medication can also be reduced.
