Nutrigenomics- Developing Personalised Diets for Disease Prevention
Nutrigenomics focuses on the effect of nutrients on the genome, proteome, and metabolome. It is applying the sciences of genomics, transcriptomics, proteomics and metabolomics to human nutrition in order to understand the relationship between nutrition and health. In order to address the increasing incidence of these diet-related-diseases, the role of diet and nutrition has been and continues to be extensively studied. Nutrigenomics has been defined as the application of high-throughput genomic tools in nutrition research. The term high throughput tools in nutrigenomics refers to genetic tools that enable literally millions of genetic screening tests to be conducted at a single time. When such high throughput screening is applied in nutrition research, it allows the examination of how nutrients affect the thousands of genes present in the human genome.
Nutrigenomics involves the characterization of gene products and the physiological function and interactions of these products. This includes how nutrients impact on the production and action of specific gene products and how these proteins in turn affect the response to nutrients. In future, nutrigenomics may potentially help guide the development of customized diets based on an individual’s genetic make-up. Genetic disorders which cause pathological effects were described.
