It analyzes how nutrients affect genes (influence on gene expression and function) and how genes affect diet (how an individual responds to nutrients). The individual genotypic variations can alter nutrient metabolism. Nutrigenomics has various benefits and applications as biomarkers, developing strategies for prevention of diseases, designing functional foods, identification of pathways and candidate genes, improving production and reproduction and make a pathway towards personalized nutrition. Nutrigenomics approaches promise to set new standards for nutritional research and will revolutionize the views of nutrient requirements and interactions.enVeterinary ScienceArticle
