Nutrigenomics studies how diets interact with our genes to influence our health. It's a branch of nutrition where molecular technologies like DNA tests are utilised to learn about people's food responses. Nutritional genomics, also known as nutrigenetics, is the discipline that investigates and describes gene variants linked to variable responses to specific nutrients, as well as linking this variation to diseases such as cardiovascular disease (CVD) linked to obesity. Nutrigenetics and nutrigenomics have a lot of potential for improving dietary guidance for the general population, genetic subgroups, and individuals. Because nutrigenetics and nutrigenomics necessitate a thorough understanding of nutrition, genetics, biochemistry, and ever-evolving 'omic' technologies, it can be difficult for even the most educated professionals to grasp their significance in the practise of preventive approaches for enhancing health, delaying disease onset, and reducing disease severity.
