Until recently, the nutrition researchers were interested mainly in the nutrient deficiencies or excess and, consequently, in their harm on health or production characteristics of organisms. The turning point came with the sequencing of various mammalian genomes. The sequencing brought forth a lot of useful information about the genome's structure, which can facilitate the study about the impact of the interaction between genes and various factors from the environment. Consequently, new technologies have been designed, and are continually developing, to enable the studies of how the nutrition relates to a state of health or disease. For example, 'transcriptomics' monitor the activity of multiple genes simultaneously at the level of the RNA, or 'proteomics' which research the genes' activities at the level of the proteins. Further on, the genome information encouraged the studies of the role of genetic variations to explain individual's responses to nutrition. These new areas of science, referred to as 'nutrigenomics' and 'nutrigenetics', will increase our fundamental knowledge of the interplay between life processes and our diet, or specific components of them. In the future, we can expect the development of novel functional food, which might improve the health status of general population, and also prevent the food related disorders in genetically predisposed individuals.
