n. the branch of genetics concerned with the study of genomes. It includes both the mapping of genomes – and ultimately producing a DNA sequence for any particular organism or individual – and understanding how gene expression is controlled and gene products change under different conditions, including disease states.
the study of the relationships between the human genome, nutrition, and health. There are two main branches of study: nutrigenetics investigates how an individual’s genes affect their response to certain dietary nutrients, whereas nutrigenomics investigates how nutrients ingested can modulate gene expression. In time, nutrigenomics may help to identify the aetiology of certain chronic diseases.... nutritional genomics
