Nutrigenomics (also known as nutritional genomics) is broadly defined as the relationship between nutrients, diet, and gene expression. The launch of the Human Genome Project in the 1990s and the subsequent mapping of human DNA sequencing ushered in the ‘era of big science’, jump-starting the field of nutrigenomics that we know today.

Nutrigenomics as a research field very much depends on the recent development of advanced technologies that allow us to process a large amount of data relating to gene variants. These so-called ‘-omics’ technologies: genomic, proteomic, metabolomic and transcriptomic, allow us to identify and measure many different types of molecules simultaneously.
