We can now get a molecular understanding of human physiology due to better systems research and omics-based technology. Single omics technologies, such as metabolomics, proteomics, and transcriptomics, have led to the discovery of biomarkers for diseases and dietary intake, as well as a better understanding of disease pathophysiology and aetiology. They've also been used to investigate the impact of the environment on health. To properly capture the intricacy of human inter-individuality, however, methods that integrate these various technologies are required. The recent progress of technology and bioinformatic approaches has contributed significantly to the expanded usage of the omics approach in food research. Nutrigenomics, also known as nutritional genomics, nutritional omics, or nutri omics, is a food and nutrition study subject that employs comprehensive (omics) analysis of molecules or other physical phenomena.
