Nutrition and genetics both play an important role in human health as well as the development of chronic diseases such as cancer, osteoporosis, diabetes, and cardiovascular disease. Nutritional genomics, or nutrigenomics, is the study of how food and genes interact, and it aims to understand the effects of diet on an individual’s genes and health. It attempts to study the genome-wide influences of nutrition, to identify the genes that influence the risk of diet-related diseases on a genome-wide scale, and to understand the mechanisms that underlie these genetic predispositions (Muller and Kersten 2003). 84It describes a scientific approach that integrates nutritional sciences and genomics and includes the application of other high-throughput omics technologies, such as transcriptomics, proteomics, and metabolomics, to investigate the effects of nutrition on health.
