Nutrigenetics and nutrigenomics: A brief review with future prospects

Individual’s genetic makeup best describes the properties regarding its growth and development. It is stored and passed on to generations and is in dynamic equilibrium with the environmental and other non-living factors. The most predominant environmental stimuli are diet/nutrition.  Diet/nutrition interacts and modulates varying underlying molecular mechanisms central to various physiological functions basically at three different levels: genome, proteome, and metabolome. Advances in genomic studies are paving the way to the development of scientific insights into nutritional sciences. Nutrigenetics and nutrigenomics are closely associated but two different areas of nutritional research. Both the fields involved the study of the implication between nutrition, metabolism, and genetic mechanism. The primary goal is to pinpoint nutrient-dependent health characteristics and nutrition dependent diseases. Another important area connected to these sciences concerns food composition and performance of quality assessment by studying proteomics and metabolic pathways. Nutrigenomics explains how the nutrients influences or effects the expression of the, while the response of different gene variants to nutrients or different dietary components is called Nutrigenetics. A personalized based diet can help us to know the right nutrient to take or avoid those who may potentially harm overall health. The goals are intended to alter or decrease the impact of hostile dietary changes that have occurred in since past in the developed world and more recently in the developing countries.
