Nutritional genomics, also known as nutrigenomics, is a science studying the relationship between human genome, human nutrition and health. People in the field work toward developing an understanding of how the whole body responds to a food via systems biology , as well as single gene/single food compound relationships.
Nutritional epigenetics is a science that studies the effects of nutrition on gene expression and chromatin accessibility. [ 1 ] [ 2 ] It is a subcategory of nutritional genomics that focuses on the effects of bioactive food components on epigenetic events.
Nutriepigenomics. Nutriepigenomics is the study of food nutrients and their effects on human health through epigenetic modifications. There is now considerable evidence that nutritional imbalances during gestation and lactation are linked to non-communicable diseases, such as obesity, cardiovascular disease, diabetes, hypertension, and cancer.
Nutritional science. Nutritional science (also nutrition science, sometimes short nutrition, dated trophology[1]) is the science that studies the physiological process of nutrition (primarily human nutrition), interpreting the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism.
The American Nutrition Association (ANA) is a 501 (c) (3) charitable non-profit organization established to encourage the scientific investigation of nutrition and metabolism. The ANA publishes the Journal of the American Nutrition Association and hosts scientific conferences in the U.S. and in Europe. It is headquartered in Hinsdale, Illinois.
Metabolomics. The central principle of biology showing the flow of information from DNA to the phenotype. Associated with each stage is the corresponding systems biology tool, from genomics to metabolomics. Metabolomics is the scientific study of chemical processes involving metabolites, the small molecule substrates, intermediates, and ...
Genomics – applies recombinant DNA, DNA sequencing methods, and bioinformatics to sequence, assemble, and analyze the function and structure of genomes (the complete set of DNA within a single cell of an organism). [35] [36] The field includes efforts to determine the entire DNA sequence of organisms and fine-scale genetic mapping.
Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes. A genome is an organism's complete set of DNA , including all of its genes as well as its hierarchical, three-dimensional structural configuration.
